Chamber A
high precision engineering
Image by James Webb Space Telescope
NASA’s &quotChamber A&quot thermal vacuum testing chamber famous for becoming 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 designed, engineers had to guarantee there was a spot large enough to test it, thinking about it really is as massive as a tennis court. That honor fell upon the famous &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 created popular for testing the space capsules for NASA’s Apollo mission, with and without 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 three 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 correctly together in the cold temperatures of space. Additional test support gear involves mass spectrometers, infrared cameras and television cameras so engineers can hold an eye on the Webb while it’s being tested.

&quotSome of the items we’ve accomplished is upgraded our helium system, our liquid nitrogen method, and air flow management,&quot mentioned 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 mentioned Ryan Grogan, Webb Telescope Chamber A project engineer at NASA Johnson.

A extremely large clean room 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 very first 30 days will consist of cooling the chamber down. The next couple 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 space temperature.

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

Lengthy Description:
Whether or not it was the Tomahawk, Warhawk, or Kittyhawk, the Curtiss P-40 was a profitable and versatile fighter aircraft throughout the first half of World War II. The shark-mouthed Tomahawks that General Claire Chennault led against the Japanese stay amongst the most well-liked airplanes of the war. In the Phillipines, Lt. Boyd D. Wagner became the 1st American ace of Globe War II although flying a P-40E when he shot down six Japanese aircraft for the duration of mid-December 1941. P-40s had been 1st-line Army Air Corps fighters at the start of the war but they quickly gave way to more sophisticated styles such as the Republic P-47 Thunderbolt and the Lockheed P-38 Lightning (see NASM collection for each aircraft). The P-40 is not ranked amongst the best all round fighters of the war but it was a rugged, successful design and style obtainable in massive numbers early in the war when America and her allies urgently required them. The P-40 remained in production from 1939 to the finish of 1944 and a total of 13, 737 were built.

Design and style engineer Dr. Donovan R. Berlin layed the foundation for the P-40 in 1935 when he developed the agile, but lightly-armed, P-36 fighter equipped with a radial, air-cooled engine. The Curtiss-Wright Corporation won a production contract for 210 P-36 airplanes in 1937-the largest Army airplane contract awarded given that Planet War I. Worldwide, fighter aircraft designs matured swiftly during the late 1930s and it was quickly obvious that the P-36 was no match for newer European styles. High altitude efficiency in distinct became a priceless commodity. Berlin attempted to enhance the P-36 by redesigning it in to accommodate a turbo-supercharged Allison V-1710-11 inline, liquid-cooled engine. The new aircraft was designated the XP-37 but proved unpopular with pilots. The turbo-supercharger was not trustworthy and Berlin had placed the cockpit also far back on the fuselage, restricting the view to the front of the fighter. Nonetheless, when the engine was not providing trouble, the much more-streamlined XP-37 was much more quickly than the P-36.

Curtiss attempted once more in 1938. Berlin had modified one more P-36 with a new Allison V-1710-19 engine. It was designated the XP-40 and very first flew on October 14, 1938. The XP-40 looked promising and Curtiss presented it to Army Air Corps leaders who evaluated the airplane at Wright Field, Ohio, in 1939, along with several other fighter proposals. The P-40 won the competition, following some modifications, and Curtiss received an order for 540. At this time, the armament package consisted of two .50 caliber machine guns in the fuselage and four .30 caliber machine guns in the wings.

After production began in March 1940, France ordered 140 P-40s but the British took delivery of these airplanes when Paris surrendered. The British named the aircraft Tomahawks but found they performed poorly in high-altitude combat more than northern Europe and relegated them to low-altitude operations in North Africa. The Russians purchased much more than two,000 P-40s but details of their operational history stay obscure.

When the United States declared war, P-40s equipped several of the Army Air Corps’s front line fighter units. The plucky fighter at some point saw combat in nearly every theater of operations being the most successful in the China-Burma-India (CBI) Theater. Of all the CBI groups that gained the most notoriety of the complete war, and remains to this day synonymous with the P-40, is the American Volunteer Group (AVG) or the Flying Tigers. The unit was organized right after the Chinese gave former U. S. Army Air Corps Captain Claire Lee Chennault virtually 9 million dollars in 1940 to acquire aircraft and recruit pilots to fly against the Japanese. Chennault’s most critical assistance inside the Chinese government came from Madam Chiang Kai-shek, a Lt. Colonel in the Chinese Air Force and for a time, the service’s general commander.

The cash from China diverted an order placed by the British Royal Air Force for 100 Curtiss-Wright P-40B Tomahawks but buying airplanes was only a single essential step in producing a fighting air unit. Trained pilots were necessary, and rapidly, as tensions across the Pacific escalated. On April 15, 1941, President Franklin D. Roosevelt quietly signed an Executive Order permitting Chennault to recruit straight from the ranks of American military reserve pilots. Within a couple of months, 350 flyers joined from pursuit (fighter), bomber, and patrol squadrons. In all, about half the pilots in the Flying Tigers came from the U. S. Navy and Marine Corps although the Army Air Corps supplied 1-third. Factory test pilots at Bell, Consolidated, and other firms, and commercial airline pilots, filled the remaining slots.

The Flying Tigers flew their first mission on December 20. The unit’s name was derived from the ferocious fangs and teeth painted on the nose of AVG P-40s at either side of the distinctive, huge radiator air intake. The thought is stated to originate from photos in a magazine that showed Royal Air Force Tomahawks of No. 112 Squadron, operating in the western desert of North Africa, adorned with fangs and teeth painted around their air intakes. The Flying Tigers have been the initial genuine opposition the Japanese military encountered. In significantly less than 7 months of action, AVG pilots destroyed about 115 Japanese aircraft and lost only 11 planes in air-to-air combat. The AVG disbanded on July 4, 1942, and its assets, like a few pilots, became a element of the U. S. Army Air Forces (AAF) 23rd Fighter Group in the newly activated 14th Air Force. Chennault, now a Brigadier Common, assumed command of the 14th AF and by war’s finish, the 23rd was one particular of the highest-scoring Army fighter groups.

As wartime experience in the P-40 mounted, Curtiss produced numerous modifications. Engineers added armor plate, greater self-sealing fuel tanks, and more potent engines. They modified the cockpit to enhance visibility and changed the armament package to six, wing-mounted, .50 caliber machine guns. The P-40E Kittyhawk was the very first model with this gun package and it entered service in time to serve in the AVG. The final model created in quantity was the P-40N, the lightest P-40 constructed in quantity, and considerably faster than prior models. Curtiss built a single P-40Q. It was the quickest P-40 to fly (679 kph/422 mph) but it could not match the performance of the P-47 Thunderbolt and the P-51 Mustang so Curtiss ended development of the P-40 series with this model. In addition to the AAF, many Allied nations bought and flew P-40s which includes England, France, China, Russia, Australia, New Zealand, Canada, South Africa, and Turkey.

The Smithsonian P-40E did not serve in the U. S. military. Curtiss-Wright constructed it in Buffalo, New York, as Model 87-A3 and delivered it to Canada as a Kittyhawk IA on March 11, 1941. It served in No. 111 Squadron, Royal Canadian Air Force (RCAF). When the Japanese navy moved to attack Midway, they sent a diversionary battle group to menace the Aleutian Islands. Canada moved No. 111 Squadron to Alaska to assist defend the region. Soon after the Japanese threat diminished, the unit returned to Canada and ultimately transferred to England without its P-40s. The RCAF declared the NASM Kittyhawk IA surplus on July 27, 1946, and the aircraft ultimately returned to the United States. It had a number of owners before ending up with the Explorer Scouts youth group in Meridian, Mississippi. For the duration of the early 1960s, the Smithsonian began browsing for a P-40 with a documented history of service in the AVG but discovered none. In 1964, the Exchange Club in Meridian donated the Kittyhawk IA to the National Aeronautical Collection, in memory of Mr. Kellis Forbes, a regional man devoted to Boys Club activities. A U. S. Air Force Reserve crew airlifted the fighter to Andrews Air Force Base, Maryland, on March 13, 1964. Andrews personnel restored the airplane in 1975 and painted it to represent an aircraft of the 75th Fighter Squadron, 23rd Fighter Group, 14th Air Force.

Quoting from Wikipedia | Curtiss P-40 Warhawk:

The Curtiss P-40 Warhawk was an American single-engine, single-seat, all-metal fighter and ground attack aircraft that very first flew in 1938. It was utilized by the air forces of 28 nations, including those of most Allied powers throughout Planet War II, and remained in front line service until the end of the war. It was the third most-developed American fighter, right after the P-51 and P-47 by November 1944, when production of the P-40 ceased, 13,738 had been built, all at Curtiss-Wright Corporation‘s major production facility at Buffalo, New York.

The P-40 design and style was a modification of the preceding Curtiss P-36 this reduced development time and enabled a speedy entry into production and operational service.

Warhawk was the name the United States Army Air Corps adopted for all models, making it the official name in the United States for all P-40s. The British Commonwealth and Soviet air forces utilized the name Tomahawk for models equivalent to the P-40B and P-40C, and the name Kittyhawk for models equivalent to the P-40D and all later variants.

The P-40’s lack of a two-stage supercharger created it inferior to Luftwaffe fighters such as the Messerschmitt Bf 109 or the Focke-Wulf Fw 190 in higher-altitude combat and it was hardly ever used in operations in Northwest Europe. Amongst 1941 and 1944, however, the P-40 played a essential role with Allied air forces in 3 main theaters: North Africa, the Southwest Pacific and China. It also had a important part in the Middle East, Southeast Asia, Eastern Europe, Alaska and Italy. The P-40’s efficiency at high altitudes was not as critical in these theaters, exactly where it served as an air superiority fighter, bomber escort and fighter bomber.

P-40s 1st saw combat with the British Commonwealth squadrons of the Desert Air Force (DAF) in the Middle East and North African campaigns, in the course of June 1941. The Royal Air Force‘s No. 112 Squadron was among the first to operate Tomahawks, in North Africa, and the unit was the 1st to feature the &quotshark mouth&quot logo, copying comparable markings on some Luftwaffe Messerschmitt Bf 110 twin-engine fighters. [N 1]

Even though it gained a post-war reputation as a mediocre design and style, appropriate only for close air help, more recent analysis such as scrutiny of the records of person Allied squadrons indicates that the P-40 performed surprisingly properly as an air superiority fighter, at times suffering serious losses, but also taking a really heavy toll on enemy aircraft. The P-40 presented the added advantage of low expense, which kept it in production as a ground-attack fighter extended after it was obsolete in the air superiority part.

As of 2008, 19 P-40s were airworthy.

Present Situation of Abrasive Belts Grinding & Major Application

Present Situation of Abrasive Belts Grinding & Major Application


Zhengzhou, China (PRWEB) November 12, 2014

With the continuous improvement of modern day machining and the emergence of all sorts of new components as well as the rising demand for machining precision and surface roughness, corresponding sophisticated grinding strategies and abrasives goods, specifically coated abrasives, are establishing towards higher efficiency, longer service life, and super precision. Abrasive belt grinding techniques have stepped into an era of modernized development. Industrial created nations in Europe and America attach fantastic value to the R&ampD and application of grinding techniques. Even though the abrasive belts’ working life has been improved, the application fields are expanding: abrasives belts can be utilized in wet grinding, dry grinding, high-speed grinding, and higher precision components polishing. The powerful, higher-speed, higher-effective, and precision abrasive belts are not restricted to higher-method coated abrasives products, but far more of products with high added worth. The high quality and regular of abrasive belts is a symbol of a nation’s comprehensive level of coated abrasives and can bring high economic benefits.

&#13

Current Scenario of Abrasives Belts

&#13

The worldwide developing trend of abrasive belts is speedy. Given that 1960s, the development of electrostatic abrasive grain dispensing and coated abrasives technologies have helped industries developed nations, such as some European nations, America, and Japan, made enormous achievements. With the emergence of special coated abrasives (ceramic abrasives, abrasive compound, grouped abrasives, etc), all varieties of abrasive belts produced of diamond, CBN, zirconia alumina, ceramic abrasives, abrasive compound, and grouped abrasives sprang up. Diamond abrasive belts developed by Japan are successful in processing some supplies of higher hardness, such as monocrystalline silicon wafer. Internationally known brands of abrasive belts contain 3M, Norton, Hermes, VSM, Klingspor, DEER, and so on. Abrasive belt grinders exist in a variety of types. With the development of automation technology, CNC abrasive belt grinder and robot abrasive belt grinding center have been applied.

&#13

As a kind of elastic grinding, abrasive belt grinding is a compound method that has the functions of grinding, lapping, and polishing. Considering that the abrasive grains on abrasive belts have a far more potent grinding force than the grinding wheels, the grinding efficiency is really higher in three aspects: removal rate, grinding ratio, and abrasive belt machine tool power availability. Abrasive higher-price grinding has been applied in foreign nations to attain high removal price of metal. So far, the recognized abrasive belt removal rate of steel has exceeded 700cm3/cm•s. Abrasive belt grinding ratio is far beyond the grinding wheels, and abrasive belt machine tool energy availability reached 80% early in the preliminary period. The figure is as higher as 96% presently. For that reason, abrasive belt grinding technique has turn out to be an important approach for industrial developed nations to gain high economic rewards.

&#13

Use of Abrasive Belt Grinding

&#13

Abrasive belt grinding has formed a full and systematic processing approach soon after 3 decades’ development. It is popular among users thanks to its higher grinding efficiency, wide application fields, strong adaptability, low charges, and simple-to-deal with characteristics. In foreign countries, abrasive belts are capable of processing all kinds of engineering components. Elastic and higher efficiency cold cutting abrasive belts have been extensively used in massive flat thick and thin sheet materials, metal and nonmetal workpieces, complex workpiece forming grinding and polishing, metal tube cylindrical grinding and internal grinding, and so on. Dry grinding disc can replace polishing wheels in polishing approach and be utilized in chip removing and rust removing of massive boxes, ships, and bridges.

Baymard Institute Study Finds Major Troubles with Search on Major E-Commerce Sites

Baymard Institute Study Finds Major Troubles with Search on Major E-Commerce Sites


BURLINGTON, MA (PRWEB) November 12, 2014

A recent study by the Baymard Institute (http://www.baymard.com), an independent web investigation institute with a focus on e-commerce usability and optimization, discovered that numerous of the leading 50 U.S. e-commerce internet sites are lacking essential e-commerce search capabilities which is hindering existing on the internet sales. In response, EasyAsk (http://www.easyask.com), the major provider of e-commerce search options for e-retail, mobile commerce and B2B commerce, has released a white paper detailing how e-commerce organizations can improve their website search with unique functions to increase their e-commerce sales and prepare for the mobile commerce wave.

&#13

The Baymard Institute performed a usability study on user search behavior and benchmarked the top 50 grossing U.S. e-commerce sites primarily based on 60 distinct usability recommendations. The report released by the Baymard Institute, E-Commerce Search Usability, explained these recommendations and showed the final results of the benchmark tests on the top U.S. e-commerce sites.

&#13

“When e-commerce search functions, it’s quickly, practical and effective. It is no wonder that so a lot of users prefer searching more than clicking categories. Sadly, our recent massive-scale usability study and leading-50 benchmark of e-commerce search finds that search typically does not perform very effectively,” stated Christian Holst, Baymard Institute co-founder.

&#13

The Baymard Institute study identified main issues in e-commerce search usability at the top 50 U.S. e-commerce internet sites. Part of the study focused on the kind of searches typically performed by visitors, classifying diverse searches into 12 groups. When benchmarking the major U.S. e-commerce sites, the study discovered generally poor test final results for selection of search capabilities, like the following:&#13

&#13
64% of internet sites did not adequately support solution sort searches and required the user to use the precise internet site jargon for items, solution types or categories,&#13
60% of internet sites didn’t assistance supply assistance for thematic searches such as “spring jacket” or “living room rug,”&#13
Only 46% of internet sites totally supported searches employing product characteristics such as colour or other item qualities,&#13
34% of websites had no tolerance for incorrect spelling, generating poor or no benefits when a visitor misspelled even a single character in a search term.

The EasyAsk white paper, Enhancing E-Commerce Search to Meet the Wants of the Modern Shopper, identifies certain solutions for the problems identified in the Baymard Institute Study.
