Helwan HA-300

History
The Egyptian Helwan (also Haluan or Heluan) HA-300 lightweight jet fighter is an exotic and enigmatic aircraft. It is quite unique by being the lightest Mach 2 fighter ever built (at a take off weight of 3.200 kg for the first prototype and 4.500 kg for the planned series version). It was the last jet fighter conceived under the direction of Willy Messerschmitt, and in its later stage (after Messerschmitt dropped out of the project) the development team was actually headed by Kurt Tank, that other famous German designer. And it was truly cosmopolitan from its conception onward.

The development actually started in 1952 in Spain, based on late WW2 developments undertaken in Oberammergau. With declining Spanish interest, Messerschmitt must have been quite happy when Egypt signed a contract in 1959 to continue the development of this fighter.

The final development resulted in a tailed delta configuration, not unlike the MIG 21. Power for the small and light delta fighter came from a Bristol Orpheus 703 engine in the first two prototypes, whereas the third prototype and the series were planned for the locally developed Brandner/EGAO E-300.

The project team consisted of Egyptian, German, Swiss, Spanish and Austrian members. As they did not have any experienced local test pilots, Egypt sought and found help from another non-aligned country: India provided Kapil Bargava for the flight tests.

The first prototype flew for the first time on March 7, 1964, the second prototype (depicted in the model) on July 22, 1965. While the prototypes displayed pleasing handling characteristics not unlike the similar (but lower performance) Folland Gnat, there was little doubt about its inferiority to the MIG 21, which had at that time already entered service with the EAF. This, combined with the very slow development process and economic problems in Egypt finally led to the cancellation of the whole project. The third prototype (powered by the Brandner engine) was completed and ground tested, but never flew. In May 1969 - 17 years after the development had started! - the curtain finally fell for Messerschmitt´s last fighter.
The second prototype has actually survived the cancellation. It was transferred to Germany in the early 90's and found its place in the Oberschleissheim Air Museum just outside of Munich.

Remarks
After the Second World War, Professor Willy Messerschmitt for some years worked in Spain where he designed the HA-200 jet trainer, which first flew in 1955. Even two years before, design studies were started on a small Mach 2 interceptor, designated P 300. This led to the construction of a glider as proof of concept vehicle (HA-300P). As Spanish interest in the project vaned and funds dried up, the whole programme was transferred to Egypt.
There the first prototype HA-300 made its maiden flight on 7 March 1964, with Indian test pilot Kapil Barghava at the controls. The second prototype followed on 22 July 1965. With the Orpheus engine, the aircraft was severely underpowered, but development of the planned Brandner E-300 did only progress slowly. Finally, the programme was cancelled in 1969, even though a third protoype with the E-300 had started taxi test already​

Helwan HA-300

Development
The Helwan HA-300 was orginally designed in Spain by Professor Willy Messerschmitt, who headed a German-Spanish design team, to meet a Ejercito del Aire (EdA) (Spanish Air Force) requirement. The development was initiated by the Spanish Hispano-Aviacion concern who produced a full-scale glider model, designated HA-23P, before the programme was transferred to Egypt in 1960. The United Arab Republic (UAR), consisting of Egypt, Syria and Yemen, assumed the sponsorship of the programme and it was controlled by the Egyptian General Aero Organisation (EGAO). Test facilities and workshops for the development of the fighter and the powerplant were built at Helwan.
The HA-300 was orginally conceived as a tailless delta, powered by one Bristol Siddeley Orpheus B.Or.12 turbojet, rated at 3,057 kg dry and 3,706 kg with reheat. The maximum speed should be Mach 1.5. Before the programme was transferred to Egypt, a swept tailplane was introduced at the base of the rear fuselage, so a similar configuration to the Mikoyan-Gurevich MiG-21 'Fishbed' was adopted, and considerable developemnt of the basic design was then undertaken by German, Spanish and Egyptian engineers, who adapted the design for the E-300 turbojet and for speeds in the order of Mach two.


Structure
The HA-300 was a very small aircraft, roughly comparable with the Fiat G.91 and the Northrop F-5A/B Freedom Fighter, and had a mid-mounted delta wing with a thickness/chord ratio of about four per cent and a leading edge sweep of 57.5 degrees. In view of the moderately large approach incidences associated with highly loaded deltas such as the HA-300, the pilot of the HA-300 would appear to suffer an exceptionally poor view for landing, and it is therefore possible that in the production variant some form of mechanical nose dropping would have been used.

Powerplant
The Bristol Siddeley Orpheus turbojet was initially planned to power the HA-300, but it was not powerfull enough for the HA-300 to reach supersonic speeds. The E-300 turbojet was developed by a team headed by Dr. Ferdinand Brandner, who came from Austria to Egypt to assist in the development of the E-300 turbojet.
During a visit to Egypt in early 1963, the Vice President of India, Dr. Zakir Hussain, was asked by the Egytian Air Force Chief, M. Sidky Mahmout, for help with the HA-300 programme. In fact, Egypt wanted only help for the development of the E-300 engine and an Indian test pilot.

A test rig for the E-300 turbojet was build at Military Aircraft Factory Number 36 at Helwan, where Indian engineers assisted in the development of the E-300 turbojet, which ran for the first time in July 1963. The HA-300 had lateral intakes, possible derived from the intakes of the Lockheed F-104G Starfighter, for the E-300 turbojet.

To test the E-300 turbojet, an example was fitted to the left inboard position of an Egyptian Air Force (EAF) Antonov An-12 'Cub', where it replaced the Ivchyenko Al-20K turboprop. This An-12 was damaged on 5 June 1967 by IDF/AF Sud-Ouest SO.4050A Vantours at Helwan.

India supported the development programme for the E-300 turbojet, because India planned to use the E-300 on the Hindustan Aircraft Limited (HAL) HF-24 Marut. A modified HF-24 Mk IBX was loaned, and later given, to Egypt for engine trails with the E-300 turbojet. Thirty engineers from HAL were send to Egypt to maintain the aircraft.


Armament
The planned armament for the intercept mission consisted of two to four infra-red (IR) homing air-to-air missiles, such as the Russian AA-2 'Atoll', and two 30 mm Hispano cannon or four 23 mm Nudelmann-Suranov NS-23 cannon would have been used for the ground attack role, although the high loaded delta configuration offered serious shortcommings in the latter role.

Flight Trails
The Egytian Air Force Chief, M. Sidky Mahmout, was invited by HAL in early 1963 and he asked Group Captian Kapil Bhargava of the Indian Air Force (IAF) to became the testpilot for the HA-300. He came to Egypt in June 1963 and flew more than 100 flight hours with aircraft powered by the E-300 turbojet.
Two Egyptian pilots were send to India in 1964 where they attended the Indian Air Force test pilot school to prepare for the flight development of the HA-300. Major Zohair Shalaby was a pilot of exceptional ability and Major Sahby al-Tawail was both a pilot and an engineer. Both of these officers completed the course succesfully.
The first prototype made its first flight on 7 March 1964, piloted by Group Captian Kapil Bhargava. The first HA-300 was powered for the initial trails by a 2,200 kg Bristol Siddeley Orpheus 703-S-10 turbojet. In the initial form, the aircraft was intended for relative slow speed trails, having subsonic engine air intakes and a non-powered rudder.
The second prototype, which joined the test programma on 22 July 1965, had the same powerplant as the first prototype, but had supersonic intakes and a power control for the rudder. With the Orpheus 703-S-10 turbojet, the HA-300 attained Mach 1.13 .
The third prototype, which was the first with the E-300 turbojet, began taxi trails in November 1969, but the programme was cancelled without flight testing being undertaken with the third prototype.

Cancellation
The HA-300 programma was cancelled in 1969, due to the limited exceptions of the E-300 turbojet and thus the lack of a suitable powerplant and the Six Day War of June 1967. After the HA-300 was cancelled additional Soviet aircraft were ordered.
At the start of the HA-300 programme, it was planned to built additional prototypes and pre-production aircraft to join the flight programme during the course of 1965, and that the delivery of production aircraft would have been started before the end of 1966 or early 1967. Later, this date was set at 1968. The production of the HA-300 would have taken place at Military Aircraft Factory Number 36 at Helwan.
