Tupolev SB aircraft was conceived as a bomber, overtaking fighters. It was natural to create a heavy fighter, designed primarily to combat the bombers. Total produced three prototypes of the SB. According to the decision of the meeting of February 14, 1934, one of them got American motors “Cyclone”, another French Hispano-Suiza, and the third was going to keep in reserve in the form of a set of units. Three days later appeared a decree of the Council of labor and defense (STO), which stated that the third prototype of SB should be equipped with the type of engine, which is better to manifest themselves on tests.

Four-engine passenger turboprop aircraft L-188 was created under the requirements of the airline “American airlines”. In June 1955 the project was chosen from among submitted various aircraft manufacturing firms in the USA. New car interested in other airlines. The prototype of the “Electra” took to the skies on 6 December 1957, the serial production at the plant of the company “Lockheed” in Baer Bank began in October, 1958 January 12, 1959 the aircraft, “Eastern air lines” made the first flight from new York to Miami.
Sweden was and remains one of the few countries in the world, able to create a world-class aircraft. Combat aircraft of that Scandinavian countries have always been some kind of “twist”, they should not be confused with similar machines from other countries. In a world quite similar to each other planes, but similar to the Swedish fighter, perhaps, could not be found. The explanation, in my opinion, is simple: since its inception in the late 1930-ies the Swedish aviation industry is not copied already built foreign aircraft, designed and built their own samples. And the fact that in a short time the Scandinavian engineers to develop could not (for example, modern jet engines and electronic equipment) purchased abroad, including a license for their production. The result of this competent technical policy was the fact that in the postwar “jet race” Sweden is practically not inferior to the world’s leading aviation powers, and in some cases even ahead of them.
The second of may 1952 from London Heathrow airport and went to the first commercial flight to Johannesburg, the world’s first passenger jet airliner “Comet” created by the British firm “De Hevilend”. Subsequent accidents and disasters that accompanied its operation, did not stop the desire of the world’s leading aviation powers to progress and the creation of new reactive machines.
In 1933, the designers of the American company “Starman” designed the training aircraft, with a motor 215 l,p, called the “model 70”. It was an all-metal biplane with fabric covering, which had fixed landing gear with cantilever main legs and tailwheel. After successful prototype tests launched it into production.
Experimental aircraft D-558-I. In late 1944 the Douglas firm received an order to develop an experimental aircraft with a turbojet engine. The main goal of this project was to obtain information about the aerodynamic loads, stability and controllability of the aircraft at transonic speeds. These data were to complement the information obtained in the course of implementation of the programme of tests of a supersonic aircraft X-1. In accordance with the specification developed by NACA (national Advisory Committee for Aeronautics) the aircraft was to take off from the aerodrome, to gain height from 6000 to 10,600 m, within 10 minutes to fly at transonic speeds and then return to the airfield.
Training U-2 aircraft – single-engine biplane of wooden construction with fixed landing gear, was designed at the factory number 1 in Moscow under the leadership of H. H. Polikarpov. His first version took off in the beginning of 1927, the Basis for the series was the second option, took to the air July 1, 1928
An Italian bomber FIAT BR.20 Cicogna. Italian aircraft FIAT BR.20 Cicogna (Italian. — AIST), created in the prewar years, engineer, Celestino Rosatelli, differed from the other two-engine bombers in service with the Italian air force. He had a successful design was completed with the most modern equipment and could carry an impressive bomb load. Combat patrol bomber began in the skies of Spain and ended with the end of world war II on the allied side of Germany, the Italian air force.
Developing the concept of training plane DH.60, John. De Havilland has created a new aircraft of the same class – DH.60T. He was distinguished by a reinforced airframe, a modified biplane gearbox and motor “Gypsy” lll (120 HP). After releasing a small series of DH.60T went into production DH.82 with the increased chord of the lower wing. The first flight of a machine called “tiger moth”, was held on 26 October 1931
HISTORY OF PS-35 (ANT-35). At the end of 1930-ies in the Soviet air force began to penetrate American airliner DC-3, launched in Khimki under designation PS-84. Later this machine became widely known as Li-2. “American” quickly moved “in the shadow” of the passenger aircraft of national design, including the Tupolev PS-35. The history of the past is very interesting. Almost all know that A. N. Tupolev managed to significantly speed up the creation of the first Soviet passenger jet Tu-104, using units of long-range bomber Tu-16. But such a trick the designer had done in the past – a shining example of this was the PS-35. The basis for it was the famous high-speed bomber SB.
