====Albert Fonó====

In 1915, Hungarian inventor [[Albert Fonó]] devised a solution for increasing the range of [[artillery]], comprising a gun-launched projectile 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. Fonó submitted his invention to the [[Austro-Hungarian Army]], but the proposal was rejected.<ref name="Gyorgy">{{cite journal |last1=Gyorgy |first1=Nagy Istvan |title=Albert Fono: A Pioneer of Jet Propulsion |journal=[[International Astronautical Congress]] |publisher=[[International Astronautical Federation|IAF]]/[[International Academy of Astronautics|IAA]] |year=1977 |url=http://iaaweb.org/iaa/Studies/history.pdf}}</ref> After World War I, Fonó returned to the subject. In May 1928 he described an "air-jet engine" as suitable for high-altitude supersonic aircraft, in a German patent application. In an additional patent application, he adapted the engine for subsonic speed. The patent was granted in 1932 (German Patent No. 554,906, 1932-11-02).<ref>{{cite book |last=Dugger |first=Gordon L. |title=Ramjets |publisher=[[American Institute of Aeronautics and Astronautics]] |year=1969 |page=15}}</ref>
