The '''Brandner E-300''' was an Egyptian [[turbojet]] engine, developed for the [[Helwan HA-300]] light jet fighter.
==Development== Austrian engineer [[Ferdinand Brandner]], who had worked in the [[Soviet Union]], leading the development of the [[Kuznetsov NK-12]] [[turboprop]], the powerplant of the [[Tupolev Tu-95]] bomber, moved to Egypt to lead a team to design an engine to power the [[Helwan HA-300]] jet fighter that was simultaneously being designed by a team of Germans led by [[Willy Messerschmitt]].
The new engine underwent bench testing in 1963, and was flight tested under the wing of an [[Antonov An-12]], before being installed in a [[HAL HF-24 Marut]] for high speed testing, in which form it flew on 29 March 1967.<ref name="Janes 69 p671">Taylor 1969, p. 671.</ref> The E-300 was installed in the third HA-300 prototype (the first two were powered by [[Bristol Siddeley Orpheus]] engines), but testing stopped in the taxi-test stage before flight tests. The programme of HA-300 was abandoned in May 1969.<ref name="Info">{{cite web | url = http://www.bharat-rakshak.com/IAF/History/1960s/Kapil-HA300.html | title = Messerschmitt's HA-300 and its Indian Connection | publisher = Indian Air Force | author = Group Captain Kapil Bhargava | work = Memoirs | accessdate = 2008-08-08 | url-status = dead | archiveurl = https://web.archive.org/web/20080705050530/http://www.bharat-rakshak.com/IAF/History/1960s/Kapil-HA300.html | archivedate = 2008-07-05 }}</ref>
