| Originally conceived to meet a Spanish Ejercito del Aire
requirement for a small M=1.5 interceptor and the design
responsibility of a Germano-Spanish team supervised
by Prof Willy Messerschmitt, the HA-300 programme
was transferred to Egypt. Here development
and construction was undertaken in Factory No 36 at
Helwan, this being controlled by the Egyptian General
Aero Organisation (EGAO). Originally designed for the
proposed afterburning Orpheus BOr 12 turbojet, the
HA-300 was modified for the Brandner-designed E-300
with a calculated afterburning rating of 4800kgp. The first prototype, powered by a
2200kgp Orpheus 703-S-10, was flown on
7 March 1964, a similarly-powered second prototype
flying on 22 July 1965. The definitive third prototype
with the E-300 engine commenced taxi trials in November
1969, but the HA-300 programme was then terminated
without flight testing of this prototype being
undertaken. It was anticipated that the E-300-powered
HA-300 would be capable of attaining 12000m and M=2.0 within 2.5 min of take-off. The
Orpheus-powered prototypes achieved approx M=1.13
during flight test.

www.e-sac.org /articles /scripts /article.php?id=13&tit=Helwan-300%3A+The+Egyptian+Interceptor+Project&cat=avart reply | | Marc, e-mail, 19.02.2008 14:21 I liked this fighter, a nice effort by Egypt with its foreign partners to bring it to the fore. Mind you, I don't think it's fair to say France took its inspiration from it - more the other way around, as the Mirage III started development in the mid 1950's reply | | Mohamed Bahaa, e-mail, 15.11.2007 03:03 I also have a very confusing contradiction, nearly all references state that the first maiden flight for HA-300 was on 1964, but the indian test pilot who flew the aircraft says the flight was on 1963, so where's teh truth ??

HELWAN is a premier traning plane with front engine
but ALQAHIRA was have 2 versions :
1- ALQAHIRA-200 FOR essintial traning with 2 seats
2- ALQAHIRA-300 for ground support reply | | Mohamed Bahaa, e-mail, 27.08.2007 17:33 I have visited the no. 36 factory in Egypt myself, i heard this aircraft was something to be proud of in its times, i even heard that the French took their ispiration for Mirages fromthis aircraft, the question is: Why was the program terminated??? with no resumes after ???? reply |
