In Russia create a pulsating jet engine

Scientific and Technical Center of Cradles, a subsidiary of the scientific production association "Saturn" is developing a pulsating jet engine. On this, as reported by ITAR-TASS news agency, said the managing director of "Saturn" Ilya Fedorov. Development is carried out in parallel with the project long-term engine of the second stage ("Article 129") for the fighter T-50 (PAK FA). Fedorov said he "Saturn" is working "on prospective aircrafts next phase," which may be unmanned.

On the development of which kind of pulse motor in question, Fedorov did not elaborate. At present there are three types of pulsating engines — valve, valveless and detonation. Operation of the power plant is periodically supplied to the combustion fuel and oxidant which ignites the fuel mixture and the outflow of combustion gases from the nozzle to form a jet thrust. It is believed that the pulsating engine is simple and cheap to manufacture.

Pulsating air jet engine was invented in the late XIX century, the Swedish engineer Martin Wiberg. The new power plant has been developed during the Second World War and the standard used by the German cruise missiles V-1. These missiles installed engine Argus As-014 manufactured by Argus-Werken. The power plant is inferior to the already existing at the time of aircraft engines, but it was cheap and easy to manufacture.

Currently, several major defense companies in the world are engaged in research in the field of high-performance pulse jet engines. In particular, the work of leading French company SNECMA and U.S. General Electric and Pratt & Whitney.
