Fokker/Republic Aviation D-24 Alliance
Supersonic V / STOL fighter plane In the early sixties.
NATO the Basic Military Requirement 3.
There was organized a competition for a supersonic V / STOL fighter aircraft for the AC / 169 specification.
Served in January 1962, four manufacturers submit their design to NATO.
Dassault with the Mirage IIIV, BAC with Model 584, Hawker with Model P.1154 and Fokker-Republic with the D.24 Alliance.
It soon turned out that the P.1154 was technically superior to the other participants.
NATO itself was unable to develop any of these designs financially and left this to the relevant person governments.
Partly because of this, the development of all models was soon discontinued and NATO BMR3 was never implemented.
history: The Fokker-Republic Project Team was stationed at Schiphol and became led by Alexander Wadkowsky from Republic Aviation.
The project team was established to design a fighter aircraft that would comply with NATO BMR-3 program.
This program called for a tactical attack aircraft with V / STOL capacity.
From the start of the collaboration, there was a lot rivalry between the employees of Fokker and Republic.
Played here nationalistic feelings play a major role, but both partners also saw each other as competitors.
Ultimately this led to an unworkable situation and became the collaboration ended.
construction: wing: The wing had a variable arrow position and consisted of a fixed delta-shaped wing combined with an adjustable wing.
The adjustable wing slid over the delta wing.

tail: Due to the special wing construction, the Alliance had no horizontal tail surfaces needed.
Single conventional rudder.
landing gear: Retractable.
engine: The Alliance was to be equipped with the Bristol Siddeley BS.100 / 3.
The Bristol had a thrust of 17 500 kg.
The BS.100 was related to the famous Pegasus jet engine which was later used in the Harrier.
Unlike the Pegasus, the BS.100 was equipped with an afterburner, the so-called Plenum Chamber Burning (PCB)
