The Moscow-based Group for the Study of Reactive Motion was a Soviet research bureau founded in 1931 to study various aspects of rocketry

A rocket is a missile, spacecraft, aircraft or other vehicle which obtains thrust from a rocket engine. In all rockets, the exhaust is formed entirely from propellants carried within the rocket before use. Rocket engines work by action and reaction...

History

GIRD was created on September 15, 1931. There were a number of amateur groups and solitary researchers in existence, but GIRD was the world's first large professional rocketry program. The group was organized as four brigades and ten projects to study rocket engines and also winged and wingless missiles. Sergey Korolev, the future leader of the Soviet space program

 headed the GIRD's 1st Brigade, which comprised Tsander's research team, transferred from the Institute of Aircraft Engine Construction (IAM). Tsander had begun to consider rocket-powered interplanetary flight as early as 1907 and was one of the founding members of the Society for the Study of Interplanetary Communication in 1924

Tsander had begun work on the OR-1 experimental engine in 1929 while still at the IAM; this subsequently became GIRD Project 01. It ran on compressed air and gasoline and Tsander used it to investigate high-energy fuels including powdered metals mixed with gasoline. The chamber was cooled regeneratively by air entering at the nozzle end and also by water circulating through a coil.

Project 02, the OR-2 engine, was designed for Korolev's RP-1 rocket-powered glider. It burned oxygen and gasoline, and its nozzle was made from heat-resistant graphite. The engine was later modified to burn alcohol, which generated less heat than gasoline, and its thrust was increased. After cooling the engine walls, the compressed oxygen entered the top end of the chamber in a swirling pattern. Fuel was injected through an atomizer at the center, to create efficient mixing and combustion.

GIRD-X

In January 1933 Tsander began development of the GIRD-X missile. It was originally to use a metallic propellant, but after various metals had been tested without success it was designed without a metallic propellant, and was powered by the Project 10 engine which was first bench tested in March 1933. This design burned liquid oxygen and gasoline and was one of the first engines to be regeneratively cooled by the liquid oxygen, which flowed around the inner wall of the combustion chamber before entering it. Problems with burn-through during testing prompted a switch from gasoline to less energetic alcohol. The final missile, 2.2 metres (7.2 ft) long by 140 millimetres (5.5 in) in diameter, had a mass of 30 kilograms (66.1 lb), and it was anticipated that it could carry a 2 kilograms (4.4 lb) payload to an altitude of 5.5 kilometres (3.4 mi).

Tsander died unexpectedly from an illness on March 28, 1933, and his engineer, Leonid Konstinovich Korneev, became the new leader of his Brigade. An exact copy of the GIRD-X can be found on Tsander's headstone in Kislovodsk.

GIRD-9

The first Soviet rocket launch was the GIRD-9, on 17 August 1933, which reached the modest altitude of 400 metres (1,312.3 ft)

It was never completed, but its design formed the basis of the later Aviavnito rocket, powered by Leonid Dushkin's 12-K engine and fueled by liquid oxygen and alcohol, which was first launched in 1936 and achieved an altitude of 3000 m (9,842.5 ft) in 1937.
