This project began with specification E6/41, dated November 1941 In her Ministry of aviation industry of great Britain has offered the firm “de Havilland air craft company” to explore the issues of creating a jet fighter and engine for it. By that time, the company proactively developed an experimental twin-boom DH’s car.99. It was a single-engine monoplane of all-metal construction with a tricycle landing gear with nose wheel. The development of the engine in April 1941 did the firm “Halford”, headed by Frank Halford, simplifying the design of the turbojet engine with centrifugal compressor and through the location of the combustion chamber between the compressor and the turbine.
REACTIVE “FRAME” DE-HAVILLAND
The weakness of the Navy of the USSR in the prewar years, tried to compensate by creating flying cruisers – multi-engined and heavily armed seaplane, able to deal with both surface and underwater ships, ground targets, and engage in mine production. As a result, in July 1931, the air force issued TSAGI reference for the development of seaplane MK-1 (ANT-22) with a lifting capacity of six tons. The plane had to fly at a speed of 300 km/h and have a radius of 1000 km. the Defensive armament was raised from four to five machine guns and two or three guns.
April 23, 1968 carrier rocket 11А511 was launched into orbit a new spacecraft 7K-OK, called the “Union”. The ship was piloted by pilot-cosmonaut, hero of the Soviet Union Vladimir Komarov. During the flight revealed a lot of failures due to the imperfections of design, what was the reason for the reduction program. On April 24th, during the descent from orbit, the crash occurred — refused recovery system of the lander. He was broken from hitting the ground, and an astronaut, unfortunately, died. It was the first victim of manned spaceflight.
During the Second world war, 15 oil refineries of Romania gave Germany more than 7% of petroleum products supplied dependent countries and satellites. The aircraft long-range and frontline aviation periodically attacked the oil-bearing regions of Romania. However, the transportation artery connecting them with the port of Constanta, continued to operate. The most vulnerable were considered section of the pipeline laid on the bottom tier of Chernovetskogo bridge over the Danube river. 
In the summer of 1932 on the initiative of H. H. Polikarpov, who worked at the Central design Bureau began development of a promising fighter-monoplane with retractable landing gear. In may next year, the BBC confirmed their interest in the car and gave Polikarpov for the task. Six months later, the client approved the layout of the aircraft, designated the TSKB-12, and in the same month, the Council of labor and defense (STO) of the USSR adopted a decision on starting the machine received the designation I-16, in serial production.
This slogan was the basis of the life and work of one of the founders of Russian space engineer Friedrich Arturovich Tsander, who developed the 20-ies of the last century one of the first projects of the spacecraft for flight to Mars. However, he was not only a dreamer — in the early 30-ies took an active part in the development of the first domestic liquid-propellant rocket engines and rockets in the famous gird.
(Bomber-torpedo bomber Nakajima B5N). The first mention of the Japanese torpedo bombers appeared almost a hundred years ago – in April 1916, when at an aircraft factory Naval Arsenal in Yokosuka, was designed by the first aircraft of this type. In its development, took an active part Navy Lieutenant Chikuhei Nakajima, the future head of the eponymous Japanese company. However, the domestic aircraft do not generate interest from the Navy, which chose to seek the assistance of foreign experts.
The first mention of the project landing version of the aircraft, biplane, future of the An-2 is dated 1944. Then his traces are lost and emerge a year later.
