The world's first ramjet-powered airplane flight took place in December 1940, using two DM-2 engines on a modified Polikarpov I-15. That August, he developed the first ramjet engine for use as an auxiliary motor of an aircraft, the DM-1. In 1939, Merkulov did further ramjet tests using a two-stage rocket, the R-3. These shells may have been the first jet-powered projectiles to break the speed of sound. The GIRD-08 phosphorus-fueled ramjet was tested by firing it from an artillery cannon. To simulate supersonic flight, it was fed by air compressed to 20,000 kilopascals (200 atm), and was fueled with hydrogen. The first engine, the GIRD-04, was designed by I.A. Yuri Pobedonostsev, chief of GIRD's 3rd Brigade, carried out a great deal of research into ramjet engines. In the Soviet Union, a theory of supersonic ramjet engines was presented in 1928 by Boris Stechkin. The patent was granted in 1932 after four years of examination (German Patent No. In an additional patent application, he adapted the engine for subsonic speed. After World War I, Fonó returned to the subject of jet propulsion, in May 1928 describing an "air-jet engine" which he described as being suitable for high-altitude supersonic aircraft, in a German patent application. Fonó submitted his invention to the Austro-Hungarian Army, but the proposal was rejected. In 1915, Hungarian inventor Albert Fonó devised a solution for increasing the range of artillery, comprising a gun-launched projectile which was to be united with a ramjet propulsion unit, thus giving a long range from relatively low muzzle velocities, allowing heavy shells to be fired from relatively lightweight guns. His patent FR290356 showed a piston internal combustion engine with added 'trumpets' as exhaust nozzles. Attempts to build a prototype failed due to inadequate materials. The ramjet was conceived in 1913 by French inventor René Lorin, who was granted a patent for his device. Arthur C Clarke credited this book with conceiving of the ramjet, and being the first fictional example of a rocket-powered space flight. L'Autre Monde: ou les États et Empires de la Lune ( Comical History of the States and Empires of the Moon) (1657) was the first of three satirical novels written by Cyrano de Bergerac that are considered among the first science fiction stories.
