Sukhoi Su-9 (1946)

The Sukhoi Su -9 (Russian Сухой Су -9, Project designation K, NATO reporting name "Type 8") was a Soviet fighter aircraft for the front section. She was the first developed by OKB Sukhoi jet aircraft.

This machine resembled some views of the optically Messerschmitt Me 262 had with this but only the engines mean. She was a twin-engine low-wing monoplane with an oval fuselage and consisted of metal, had trapezoidal wings and a braking parachute. The nose wheel was twice frosting.

History

The Su -9 was 1945/46, at the request of the armed forces from the year 1945. Goal was to reduce the backlog of aircraft as quickly as possible with TL- drive. Since our own engines were not yet available, the planes were designed for replicas German engines. Yakovlev built into an established Jak -3, an air jet engine RD -10 ( Jumo 004) instead of the piston engine in the nose section and thus created the Jak - 15th The MiG -9 was a redesign and two RD -20 ( BMW 003) had in the fuselage nose. Sukhoi decided to look at the short service life of the engines RD- 10 for maintenance- friendly installation under the wings. So there was also enough space for large fuel tanks for the fuel-intensive engines in the fuselage. Also Messerschmitt, Heinkel or Gloster went the same way in the development of its first jet fighter, the Me 262, the He 280 or the meteor.

The seating position on the wings leads to a certain visual similarity with the Me 262 The Su -9 has on closer inspection, however, nothing to do with this. Thus it possesses, for example, the absence of Soviet experience in aerodynamics at high speeds only trapezoidal and no swept wing as the Me 262 ( the He 280 and the British Meteor had no swept wing yet). But the hull shape and the chassis distinguish the machine significantly. The Me 262 has a triangular fuselage cross-section, the Su -9 a circular.

Amazingly, dismissed the Su -9 in spite of the high speeds rather unsuitable wings better flight performance than the Me 262 In almost identical in weight ( the Su -9 was with an unladen mass of 4060 kg 300 kg lighter ), it was slightly smaller, but flew 100 km further and 600 feet higher than the Me 262, the maximum speed was also higher and amounted to 885 km / h at 8000 meters (Me 262 869 km / h in 6000 meters height).

The Su -9 was quite heavily armed with a 37 mm gun NR -37 and two 23 -mm cannons NS -23 and was able to destroy itself with individual hits big bombers.

The prototype had an ejection seat, a drag chute and a hydraulic control, which was a groundbreaking novelty for a hunter. The fuselage was a metal half-shell construction. The prototype first flew on 13 November 1946 and was presented on August 3, 1947 during the air parade in Tushino the population.

For the series production of the machine was too late. When she was ready for the end of 1947, the MiG -9 and Yak- 15 have already been built in series. Once started, a license built more modern British engines made ​​it possible now to provide aircraft with more powerful engines and was stronger than the now-obsolete replicas German engines. This led to the development of the Su -9 on the Su -11 to Su- 13th As the successor model Su -11 (Project KL), not to be confused with the NATO code Fishpot supporting Sukhoi Su -11, with its developed in the Soviet Union engines Ljulka TR-1 promised better services, the project Su -9 was set. The development of the Su -11 was then Derwent not pursued RD -500 engines due to the aerodynamic now collected evidence and the unreliability of the engines in favor of the improved Su -13 with a replica of the British Rolls- Royce. The Su- 13 again was not tested because of the incipient production of the MiG -15, Yak- 23 and Il -28. Also, the Sukhoi design bureau was quite arbitrarily dissolved in November 1949, so that a trial could no longer take place.
