Sunderland has a remarkable history of innovation in shipbuilding and marine engineering. From the improvement of turret ships in the 1890s and the production of Doxford opposed piston engines following the Initial Planet War via to the styles for Liberty ships in the 1940s and SD14s in the 1960s. Sunderland has much to be proud of.

Tyne &amp Put on Archives cares for tens of thousands of photographs in its shipbuilding collections. Most of these concentrate on the ships – in distinct their construction, launch and sea trials. This set looks to redress the balance and to celebrate the perform of the males and women who have played such a important element in the region’s history. The pictures show the human side of this great story, with several relating to the globe popular shipbuilding and engineering firm William Doxford &amp Sons Ltd.

The Archives has developed a brief weblog to accompany these pictures.

Chamber A
precision engineering
Image by James Webb Space Telescope
NASA’s &quotChamber A&quot thermal vacuum testing chamber well-known for getting utilized in the course of Apollo missions has now been upgraded and remodeled to accommodate testing the James Webb Space Telescope.

When the next-generation space telescope was getting made, engineers had to make certain there was a place large sufficient to test it, thinking about it’s as massive as a tennis court. That honor fell upon the renowned &quotChamber A&quot in the thermal-vacuum test facility at NASA’s Johnson Space Center in Houston, Texas.

Chamber A is now the biggest high-vacuum, cryogenic-optical test chamber in the globe, and made renowned for testing the space capsules for NASA’s Apollo mission, with and without having the mission crew. It is 55 feet (16.8 meters) in diameter by 90 feet (27.four meters) tall. The door weighs 40 tons and is opened and closed hydraulically.

For 3 years, NASA Johnson engineers have been creating and remodeling the chamber interior for the temperature needed to test the Webb. Testing will confirm the telescope and science instrument systems will carry out effectively collectively in the cold temperatures of space. Added test assistance gear consists of mass spectrometers, infrared cameras and television cameras so engineers can preserve an eye on the Webb whilst it really is becoming tested.

&quotSome of the issues we’ve completed is upgraded our helium technique, our liquid nitrogen system, and air flow management,&quot said Virginia Rivas-Yancy, project manager, Air Flow Management Program at NASA Johnson. Temperatures in Chamber A can now drop farther than ever — down to -439.9 Fahrenheit (-262.1 Celsius or 11 degrees Kelvin) which is 11 degrees above absolute zero.

&quotThe air in the chamber weighs 25 tons, about 12 1/2 Volkswagen Beetles when all the air is removed the mass left inside will be the equivalent of half of a staple,&quot stated Ryan Grogan, Webb Telescope Chamber A project engineer at NASA Johnson.

A very big clean area is also being ready close to Chamber A exactly where the observatory will be prepped for testing. The test itself will take 90 days. The 1st 30 days will consist of cooling the chamber down. The subsequent handful of weeks will incorporate tests on the Webb’s operating systems, and the remainder of the time will be spent warming up the chamber to area temperature.

Test articles are usually inserted into the chamber by implies of a precision mobile crane, but the Webb is so huge, it will be folded up and wheeled in.

Traction Avant monocoque

Front torsion bar suspension

The Traction Avant, French for &quotfront wheel drive&quot, was made by André Lefèbvre and Flaminio Bertoni in late 1933 / early 1934. Although not the initial production front wheel drive car – Alvis constructed the 1928 FWD in the UK, Cord made the L29 from 1929 to 1932 in the United States and DKW the F1 in 1931 in Germany – it was the world’s initial front-wheel drive steel monocoque production vehicle. Along with DKW’s 1930s models, the Traction effectively pioneered front-wheel drive on the European mass automobile market place.

The Traction Avant’s structure was a welded monocoque (unitized physique). Most other vehicles of the era had been based on a separate frame (chassis) onto which the non-structural body (&quotcoachwork&quot) was built. Monocoque building (also called Unit Physique or &quotUnibody&quot in the US nowadays) benefits in a lighter car, and is now employed for virtually all vehicle building, even though body-on-frame building remains appropriate for bigger autos such as trucks.
This method of construction was viewed with wonderful suspicion in many quarters, with doubts about its strength. A sort of crash test was conceived, taking the type of driving the auto off a cliff, to illustrate its wonderful inherent resilience.

The novel design and style created the car really low-slung relative to its contemporaries – the Traction Avant usually possessed a distinctive appear, which went from appearing rakish in 1934 to familiar and somewhat old fashioned by 1955.

The suspension was really sophisticated for the car’s era. The front wheels were independently sprung, using a torsion bar and wishbone suspension arrangement,[3] where most contemporaries utilised live axle and cart-sort leaf spring styles. The rear suspension was a easy steel beam axle and a Panhard rod, trailing arms and torsion bars attached to a 3-inch (76 mm) steel tube, which in turn was bolted to the monocoque.

Because it was significantly lighter than traditional styles of the era, it was capable of one hundred km/h (62 mph), and consumed fuel only at the rate of ten litres per one hundred kilometres (28 mpg-imp 24 mpg-US).

Traction Avant rears. The boot was lengthened and its volume doubled in Autumn 1952.[four]
The original model, which was presented on 18 April 1934, was a tiny saloon with a 1,303 cc (79.five cu in) engine. This model was known as the 7A, which was succeeded in June 1934 by the 7B with a higher-power engine of 1,529 cc (93.3 cu in). The 7B in turn, was succeeded in October 1934 by the 7C with an even greater-output 1,628 cc (99.3 cu in) engine. Later models have been the 11 (launched in November 1934), which had a 1,911 cc (116.six cu in) four-cylinder engine, and the 15 (launched in 1938), with a two,867 cc (175. cu in) six. The numbers refer to the French fiscal horsepower rating, or CV. The 11 was an 11 CV, but curiously the 15 was truly 16 CV. The 11 was constructed in two versions, the 11L (&quotlégère&quot, or &quotlight&quot), which was the identical size as the 7 CV, and the normal model 11, which had a longer wheelbase and wider track.

Citroën planned two variants that by no means entered production, given that there was not enough funding available to develop them, except as running prototype automobiles. 1 was an automatic transmission-equipped model, based on the Sensaud de Lavaud automatic transmission, the other a 22 CV model with a three.8 liter V8. The transmission (which was really initially created for the Citroen) was a &quotgearless&quot automatic, employing the torque-converter alone to match engine revolutions to the drivetrain revolutions, significantly like the Dynaflow Transmission introduced later in the USA. The vehicle was supposed to have a much less spartan interior than the other Traction Avants and it was to function Citroën’s own new V8 engine. About twenty prototypes have been produced, but when the project was canceled in 1935 due to Michelin’s takeover they were most likely all destroyed.[citation required]

In addition to the 4-door physique, the auto was also produced as a two-door coupé with a rumble seat, as a convertible and as an extended length Familial model with 3 rows of seats. There was even a hatchback-kind Commerciale variant, in 1939, well ahead of its time, in which the tailgate was in two halves, the reduced of which carried the spare wheel with the upper opening up to roof level. A one-piece leading-hinged tailgate was introduced when the Commerciale resumed production in 1954 soon after being suspended during World War II.
Wartime disruption[edit]

In September 1939 France declared war on Germany and in June 1940 the German army quickly invaded and occupied Northern France.[1] The war years were characterised by a desperate shortage of raw components for civilian market and of petrol,[1] but these variables have been not apparent quickly. The Paris Motor Show scheduled for October 1939 was cancelled at quick notice, but Citroën’s personal planned announcements had involved the forthcoming 2CV model rather than any significant adjustments to the Traction.[1] For the Traction, the final “normal” year in terms of production levels was 1939, and eight,120 of the 2910mm wheelbase 1628cc engined 7C models have been developed.[1] This tumbled to 1,133 in 1940, which was the initial year when the plant suffered severe air-raid damage – on this occasion caused by a German attack – on three June 1940. Production of the vehicles was suspended in June 1941, by when a further 154 had been produced in the six-month period just ended. The 7C would continue to seem in Citroën price-lists until March 1944, but production of this smaller engined “7CV” version of the Traction was not resumed soon after the war.[1] For the a lot more powerful 1911cc engined 11 B-light models, the equivalent figures were 27,473 units created in 1939, 4,415 in 1940 and two,032 for 1941, even though for this model production in 1941 ended only in November 1941 so the figure for that year represents 11 months of production.[1]

In 1945 production restarted only slowly: the 11 B-light reappeared really tiny changed from the 1941 automobiles except that headlight surrounds were now painted rather than finished in chrome. By the end of December 1945 the year’s production had reached 1,525.[1] Currency depreciation is evident from the car’s listed cost which had been 26,800 francs in January 1940, and had risen to 110,670 francs in October 1945.[1] In 1945 the auto was the only model accessible from Citroën, and as one more sign of the instances, customers not in a position to supply their own tires were charged an extra 9,455 francs for a set of five.[1] In May possibly 1946, presumably reflecting an easing of the war-time tire shortage, the auto could at last be bought with tires at no added cost, but by now the all round price tag of an 11 B-light had risen to 121,180 francs.[1]

The 11 B-normal model, differentiated from the 11 B-light by its 3090mm wheelbase, knowledgeable a comparable drop off in volumes between 1939 and 1941, with just 341 cars produced for the duration of the first seven months of 1941.[1] Right after the war, a single 11 B-normal was developed in 1946, in time to be presented at the October 1946 Paris Motor Show: production constructed up throughout 1947, but for the duration of the car’s ten-year post-war period the shorter 11 B-light would, in France, continue to outsell the 11 B-normal.

Initially the French army lacked enthusiasm for the Citroën Traction, believing that it presented insufficient ground-clearance for their needs.[1] Nonetheless, by September 1939 roughly 250 had found their way into military service. With losses of automobiles at the frontier mounting, Citroën supplied a further 570 to the army in between February and Could 1940, and subsequent deliveries almost certainly took location just before military defeat intervened.[1] In the course of the war many of the automobiles were reregistered with &quotWH…&quot (Wehrmacht Heer/Army command) license plates, obtaining been requisitioned by the German Army.[1] These gave reliable service each in France and further afield, notably in Libya and Stalingrad. Tractions have been also favoured by the Resistance, and as occupation gave way to Liberation they turned up all more than France with FFI inscribed proudly on their doors. Less gloriously, the automobiles were identified as favourites among gangsters such as the then infamous Pierrot le Fou, and his Traction gang.

UK built automobiles[edit]

Left-hand drive versions had been built in Paris, in Forest, Belgium, in Copenhagen, Denmark for the Scandinavian market place, and correct-hand drive cars in Slough, England. The Slough version of the 11L was named the Light Fifteen and the long wheelbase 11 was referred to as the Large Fifteen. This confusing terminology referred to the British fiscal tax rating of the time, which was greater than the French, so the 11CV engine was 15HP in England. The 15CV model was known as &quotBig Six&quot in reference to its six-cylinder engine. They have been equipped with the leather seats and wooden dashboards popular in the UK, had a 12-volt electrical method and had been distinguished by a diverse radiator grille and distinct bumpers. Some models also had a sliding sunroof.
A 1,911 cc (116.six cu in) Light Fifteen tested by the British magazine The Motor in 1951 had a leading speed of 72.6 mph (116.eight km/h) and could accelerate from 0–60 mph (97 km/h) in 29.7 seconds. A fuel consumption of 25.two miles per imperial gallon (11.2 L/one hundred km 21. mpg-US) was recorded. The test car cost GB£812 including taxes.[five]

A two,866 cc (174.9 cu in) six-cylinder model was tested by the very same magazine in 1954 and for this vehicle the best speed found was 81.1 mph (130.five km/h), acceleration from 0–60 mph (97 km/h) 21.2 seconds and fuel consumption 18.six miles per imperial gallon (15.two L/100 km 15.five mpg-US). The test vehicle expense GB£1,349 like taxes.[six]
Engineering[edit]

Citroën 11 CV Légère

The Traction Avant used a longitudinal, front-wheel drive layout, with the engine set effectively within the wheelbase, resulting in a really favourable weight distribution, aiding the car’s sophisticated handling qualities. The gearbox was placed at the front of the automobile with the engine behind it and the differential among them, a layout shared with the later Renault four and 16 and initial generation Renault five but the opposite way round to numerous longitudinal front-wheel drive vehicles, such as the Saab 96 and Renault 12 and 18 and most Audi models. The gear alter was set in the dashboard, with the lever protruding through a vertical, H-shaped gate.[7] Due to the fact this vertical orientation could have resulted in the auto dropping out of gear when the lever was in the upper positions (i.e., second or reverse gears), the gear shift mechanism was locked when the mechanical clutch was engaged and released when the clutch pedal was depressed. The outcome of this layout, along with pendant pedals, umbrella-sort handbrake handle and front bench seats, was a very spacious interior, with a flat and unobstructed floor. The low-slung arrangement also eliminated the want for running boards to step into or out of the car. These features created them ideal for use as limousines and taxi cabs, and they were quite well-known among drivers and passengers alike. Until 1953, black was the only color offered.

Effect on Motorsport[edit]

Another technical significance of Tranction Avant was the cast aluminium alloy transaxle, which was pioneered by Hans Ledwinka in the early 1930s for Tatra V570 utilised in front of the engine positioned in the rear, but was really radical at the time.

As well as being a considerable component of the weight savings, the manufacturing facility for this transaxle contributed to the under talked about financial crisis. But when John Cooper looked for a light transaxle case for Formula 1 rear engine revolution, Traction Avant unit was about the only candidate, as Volkswagen magnesium alloy transaxle was a lot smaller and lacking the space needed to property heftier gears needed for Formula 1. The Traction Avant transaxle was utilised on Cooper T43 which won a F1 championship race as the very first mid-mounted engine automobile to do so in 1958, and on its successors Cooper T45, T51 and T53. Cooper T51 won the GP World Championship in 1959.

Unlike the Volkswagen alloy case used by Hewland, the Traction Avant case could not be utilized up side down, as the input shaft height was much larger in relation to the output shaft axis so that the oil level needed to lubricate the gears would exceed the then-unreliable input shaft oil seal height if employed upside down. So the engine necessary to sit higher above the ground with the oil sump space beneath, which was not necessary by dry-sump racing engines. But the French transaxle was used by numerous racing automobile constructors in the late 1950s to 60’s with various levels of success.

In the case of Jack Brabham, who personally visited the ERSA foundry in Paris to discuss a possibility to strengthen the case ,[eight] the transaxle became known as &quotERSA Knight&quot with an further spur-gear set mounted in the bellhousing spacer (engine to transaxle adapter) recommended by Ron Tauranac, named for Jack Knight who designed the modification and produced the straight-reduce gears. The height offset produced by the spur gear set enabled the engine to sit lower, and became the reason why Cooper T53 was known as the ‘Lowline’, which not only made Brabham the World Champion in 1960 but also became the precursor to the establishment of Brabham as a Formula A single constructor.

Effect on Citroën[edit]

Traction Avant as modern wedding car

The development charges of the Traction Avant, combined with the redevelopment of its factory, had been extremely high and Citroën declared bankruptcy in late 1934. The biggest creditor was Michelin, who then owned Citroën from 1934 till 1976. Beneath Michelin, Citroën was run as a study laboratory, a test bed for their radial tires and new automotive technologies.
In 1954 Citroën’s experiments with hydropneumatic technologies produced its first result, the &quot15H&quot – a variant of the 6-cylinder model 15 with a self-leveling, height-adjustable rear suspension, a field trial for the revolutionary DS released the following year.

Directly soon after the introduction of the Citroën ID, a simplified and much more competitively priced version of the nonetheless revolutionary DS, production of the Traction Avant ended in July 1957. Over 23 years, 759,111 had been built, such as 26,400 assembled in Slough in England, 31,750 assembled in Forest near Brussels and 1,823 assembled at Cologne in Germany. The total reflects the production stoppage for the duration of World War II.

The Traction Avant nowadays[edit]

In 2006, the oldest surviving 7A has production quantity (&quotcoque nr&quot) AZ 00-18, and is displayed in partly dismantled shape (engine and front wheels detached) in the Citroën Museum in Paris. The oldest operating 7A is possibly number AZ-00-23, which was, till 1 September 2006, in possession of a Dutch owner and is now with a Slovenian owner.
Traction Avants are fairly robust autos even by contemporary requirements nevertheless, they are prone to leaking water inside the cabin and care requirements to be taken when acquiring one. Each few years, Traction Avant enthusiasts ship their autos to an exotic location for a rally. In 2002, for example, a group of more than 30 Traction Avants drove from Los Angeles to New York with no incident. [1]

For also lengthy the engineers of the Kingdom’s navy laughed at the engineers of the air force, and for excellent purpose the Sky Ram produced by Meloa Industries was a disastrous tiny plane and paled in comparison to the Neustrasian’s Maelstrom supply.

But no more soon after the -ahem- &quotperfectly legal&quot &quotacquisition&quot of the subsequent generation jet engine prototype developed by the MURICANs, a secret project was contracted with Piccolo Aircraft. The majority of Meloa Industries personnel left to make naval versions of the Maelstrom for the major naval designers, but a handful of crazy, stubborn determined people joined the struggling engineers of Neustrasia’s Mayenne and a Georgian firm, founding Piccolo Aircraft which worked beneath the radar (literally, in some situations) to create the Piccolo G-92 &quotKrut&quot to outdo all other jet fighters ever created up to that point. After 92 diverse design and style prototypes (most of them dying as wooden models in air tunnels) primarily based of the Manchot, Direwolf and possibly a handful of stolen Germanikan fighters, the design and style team went through forty six pounds of coffee beans, five of some of Neustrasia’s best pilots, a few water blessings to purge demon spirits, and a certain wealthy man’s life savings going to charity after losing a bet the fighter flies, and it flies nicely! So properly, in truth, that many of its elements are classified. :^)

Also, unknown to most of the globe, but very perplexing to the military leaders of Neustrasia, all their ideal pilots not already out for active duty were mysteriously re-assigned. This is why the ideal pilots of Terra get to fly the greatest fighter of Terra. 8^)

In 1945, the group of gliding enthusiasts decided to re-activate the Silesian Glider Workshops, which had been established ahead of the Second World War. As a outcome of this initiative, the Gliding Institute was established in 1946. Its objective was to design and style new gliders, utilizing Polish encounter in this field.
The Sęp (vulture) was the very first after-war Polish building made at the Gliding Institute in Bielsko Biała. The initial style was carried our by engineers: Józef Niespał and Władysław Nowakowski. Despite hard occasions the prototype was flown on 2nd June 1947and currently in July of the very same year, the Sęp flown by Adam Ziętek represented Poland on the International Gliders Competitors in Samedan, Switzerland. It came eight. The Polish glider was the only new construction there. The other participants flew the pre-war or the captured German gliders To the subsequent examples a few minor adjustments (in the wings building and the cockpit equipment) have been introduced. The modified version bore the &quotSęp bis&quot designation.
The total production quantity (collectively with prototypes) was six gliders, the last 1 was nonetheless flying at the starting of 1960’s Flying the Sęps, the Polish glider pilots set many domestic and planet records.
The IS-1 Sęp bis, displayed, bearing the SP-552 markings, was in service from 1948 till 1960, and took part in several different championships. In 1949, Irena Kempówna established two speed records. In 1964, the glider was handed over to the museum.&quot

Quoting Smithsonian National Air and Space Museum | Vought OS2U-3 Kingfisher:

The Kingfisher was the U.S. Navy’s main ship-primarily based, scout and observation aircraft for the duration of World War II. Revolutionary spot welding strategies gave it a smooth, non-buckling fuselage structure. Deflector plate flaps that hung from the wing’s trailing edge and spoiler-augmented ailerons functioned like additional flaps to permit slower landing speeds. Most OS2Us operated in the Pacific, where they rescued numerous downed airmen, like World War I ace Eddie Rickenbacker and the crew of his B-17 Flying Fortress.

In March 1942, this airplane was assigned to the battleship USS Indiana. It later underwent a six-month overhaul in California, returned to Pearl Harbor, and rejoined the Indiana in March 1944. Lt. j.g. Rollin M. Batten Jr. was awarded the Navy Cross for generating a daring rescue in this airplane below heavy enemy fire on July four, 1944.

Quoting Smithsonian National Air and Space Museum | Boeing B-29 Superfortress &quotEnola Gay&quot:

Boeing’s B-29 Superfortress was the most sophisticated propeller-driven bomber of Planet War II and the first bomber to property its crew in pressurized compartments. Though created to fight in the European theater, the B-29 discovered its niche on the other side of the globe. In the Pacific, B-29s delivered a variety of aerial weapons: traditional bombs, incendiary bombs, mines, and two nuclear weapons.

On August 6, 1945, this Martin-constructed B-29-45-MO dropped the very first atomic weapon used in combat on Hiroshima, Japan. Three days later, Bockscar (on display at the U.S. Air Force Museum close to Dayton, Ohio) dropped a second atomic bomb on Nagasaki, Japan. Enola Gay flew as the advance weather reconnaissance aircraft that day. A third B-29, The Wonderful Artiste, flew as an observation aircraft on both missions.

Aérospatiale-BAC Concorde is a retired turbojet-powered supersonic passenger airliner or supersonic transport (SST). It is a single of only two SSTs to have entered commercial service the other was the Tupolev Tu-144. Concorde was jointly developed and created by Aérospatiale and the British Aircraft Corporation (BAC) beneath an Anglo-French treaty. First flown in 1969, Concorde entered service in 1976 and continued industrial flights for 27 years.

Among other destinations, Concorde flew typical transatlantic flights from London Heathrow and Paris-Charles de Gaulle Airport to New York JFK, Washington Dulles and Barbados it flew these routes in significantly less than half the time of other airliners. With only 20 aircraft built, the development of Concorde was a substantial economic loss Air France and British Airways also received considerable government subsidies to buy them. Concorde was retired in 2003 due to a basic downturn in the aviation sector following the type’s only crash in 2000, the 9/11 terrorist attacks in 2001, and a decision by Airbus, the successor firm of Aérospatiale and BAC, to discontinue upkeep assistance.

A total of 20 aircraft had been built in France and the United Kingdom six of these were prototypes and development aircraft. Seven each and every were delivered to Air France and British Airways. Concorde’s name reflects the improvement agreement in between the United Kingdom and France. In the UK, any or all of the type—unusually for an aircraft—are identified just as &quotConcorde&quot, without having an write-up. The aircraft is regarded by a lot of men and women as an aviation icon and an engineering marvel.
