Démonstration du Soukhoi Su 35 au salon du Bourget.
Le Soukhoï Su-35 (Flanker Plus dans le code OTAN) est un chasseur russe. Il a été créé dans le but d’accroître les capacités offensives du Su-27 et de lui donner la possibilité de détruire tant les cibles aériennes que de surface.
Le Su-35 est le premier chasseur au monde à avoir deux radars, un N-011 multimode à balayage électronique à l’avant et un N-012 dans le cône de queue. Le N-011 est capable d’acquérir 15 cibles et d’en engager eight, sa portée est de plus de 100 km pour un objectif d’une SER de ,01 m2.

The Sukhoi Su-35 (Russian: Сухой Су-35 NATO reporting name: Flanker-E) is designation of two distinct heavily-upgraded derivatives of the Su-27 ‘Flanker’. Both are single-seat, twin-engine supermaneuverable multirole fighters, developed by Sukhoi and constructed by Komsomolsk-on-Amur Aircraft Production Association (KnAAPO).
The very first variant was made throughout the 1980s, when Sukhoi was hunting to upgrade its high-efficiency Su-27, and was initially known as the Su-27M. Later re-designated Su-35, this derivative incorporates aerodynamic refinements to improve manoeuvrability, enhanced avionics, longer variety, and a more strong engine. The very first Su-35 prototype, converted from a Su-27, created its maiden flight in June 1988. Far more than a dozen of these were built with some used by the Russian Knights aerobatic demonstration team. The 1st Su-35 style was later modified into the Su-37 with thrust-vectoring engines and utilized as a technology demonstrator. A sole Su-35UB two-seat trainer was built in the late 1990s that, despite its name, shares a sturdy resemblance to the Su-30MK household.
In 2003, Sukhoi embarked on a second modernization of the Su-27 to make what the business calls a four++ generation fighter that would serve as an interim fighter prior to the arrival of the Sukhoi PAK FA. This derivative incorporates a reinforced airframe, improved avionics and radar, thrust-vectoring engines, and a lowered radar signature from the front, while omitting the canards and air brake. In 2008 the revamped variant, erroneously dubbed the Su-35BM by the media, began its flight test programme that involved four prototypes, 1 of which was lost in 2009.
The Russian Air Force has ordered 48 production units, designated Su-35S, of the newly-revamped Su-35. Each Su-35 models have been supplied to many countries, such as Brazil, China, India and South Korea, but so far have not attracted any export orders. Sukhoi originally projected that it would export much more than 160 units of the second modernized Su-35 worldwide.
North American P-51D Mustang

History: A single of the most successful, well-known and beautiful fighter aircraft of WWII, the P-51 was created to fulfill a British requirement dated April 1940. Since of the rapidly-mounting clouds of war in Europe, the UK asked North American Aircraft to style and build a new fighter in only 120 days. The NA-73X prototype was made in record time, but did not fly till 26 October 1940. The initial RAF production models, designated Mustang Mk Is, underwent rigorous testing and evaluation, and it was located that the 1,one hundred-hp Allison engine was nicely suited for low-altitude tactical reconnaissance, but the engine’s energy decreased dramatically above an altitude of 12,000 feet, creating it a poor selection for air-to-air combat or interception roles. Simply because of this, the RAF left its eight machine guns intact, but also fitted the Mustang with cameras. In this configuration, it served in at least 23 RAF squadrons, beginning in April 1942.
At the identical time, the US Army Air Corps ordered a tiny number for tactical reconnaissance evaluation as the F-6A. Right after the RAF found the aircraft’s overall performance lacking, they tested a new engine, the 12-cylinder Rolls-Royce Merlin. This gave much-enhanced functionality, and led to the USAAF fitting two airframes with 1,430-hp Packard-built Merlin V-1650 engines. These aircraft were re-designated XP-51B. Practically overnight, the aircraft’s potential started to grow.
Because the RAF had had good success with the Mustang in a ground attack part, the USAAF bought 500 aircraft fitted with dive brakes and underwing weapons pylons. These had been initially designated the A-36A Apache, but later retained the name Mustang. Almost simultaneously, they ordered 310 P-51As with Allison engines. Some of these have been delivered to the UK as Mustang Mk IIs, and some became F-6B reconnaissance aircraft for the USAAF.
The initial Merlin-engine versions appeared in 1943 with the P-51B, of which 1,988 had been constructed in Inglewood, California, and the P-51C, of which 1,750 have been constructed in Dallas, Texas. Both new versions had strengthened fuselages and four wing-mounted 12.7-mm machine guns. Numerous of these new Mustangs had been delivered to the UK as Mustang Mk IIIs, and others went to the USAAF as F-6Cs. The Merlin-powered Mustangs were specifically what the Allied bombers in Europe desperately necessary, and they became popular for their extended variety and potent higher-altitude escort capability. The most important variant, the P-51D, featured a 360-degree-view bubble canopy, a modified rear fuselage, and six 12.77-mm machine guns. 7,956 have been built, and as soon as once again, many went to the UK as Mustang Mk IVs and others became USAAF F-6D reconnaissance aircraft. Next came the P-51K, which was generally similar. A third of these became RAF Mustang IVs also, and over a hundred became F-6Ks. Really late in the war, the P-51H appeared, though only 555 of 2000 have been completed prior to V-J Day triggered the cancellation of the order. US production totaled 15,386, but at least 200 far more were built by the Commonwealth Aircraft Corporation of Australia with imported parts and designated Mustang Mk 20/21/22/23. None of these saw service ahead of the end of the war. Below the Lend-Lease plan, 50 P-51s have been supplied to China, and 40 more were supplied to the Netherlands in the Pacific theater.
Right after the war, the P-51 remained in US service with the Strategic Air Command till 1949, and with the Air National Guard and Reserves into the 1950s. It became a single of the very first fighters to see combat in the Korean War. The RAF’s Fighter Command utilized them till 1946. In addition, over 50 air forces around the planet acquired and utilised the Mustang for numerous more years, some as not too long ago as the early 1980s. When the US Air Force realigned their aircraft designations in the 1950s, the Mustang became the F-51.
In the final 40 years, surplus Mustangs have been modified and utilized extensively as civilian air racers, but the newest trend is for private owners to restore them to almost best, historically-precise situation. As public appreciation for the Mustang has grown, the monetary worth of the handful of remaining examples has skyrocketed. War-surplus P-51s, once auctioned from storage for much less than (US) 00, are now typically valued at 3-quarters of a million dollars or a lot more. The restoration of existing airframes has turn into a small market in the US, UK and Australia, and the total number of flyable examples, despite one particular or two accidents every year, is developing. A number of Mustangs have been or are at present being restored as two-seat, dual-control TF-51s, a trend which promises to guarantee that today’s operators are better-trained than any previous generation of Mustang pilots.
