British Aerospace EAP
The British Aerospace ACA or EAP was a prototype fighter aircraft developed as a private venture in the 1980s and which eventually formed the basis for the Eurofighter.
In 1982, British Aerospace exhibited the ACA (Agile Combat Aircraft) at the Farnborough Air Show as well as the Paris Air Show in May 1983. The ACA was a result of several years of private venture research by BAe, costing around £25 million.
The British Government announced it would make a financial contribution to the EAP (Experimental Aircraft Programme), which would be based on the ACA and would first fly on August 8 1986. The Ministry of Defence would eventually invest almost £80m on the EAP, the rest funded by BAe.
The Experimental Aircraft Programme was designed to research components technology to be used in a future project, named EFA (European Fighter Project, later to become the Eurofighter).
The EAP was fitted with a variety of advanced electronic equipment, including three CRT displays and a HUD similar to the F-16's. The EAP's engines were a pair of Turbo-Union RB199-104 afterburning turbofans, powerplant of the Tornado Air Defence Variant.
After several years of research by the EAP, the Eurofighter project was initiated. Without the research from the ACA/EAP projects, the Eurofighter would not have been possible. While the similarity between the EAP and the Typhoon is striking there are some importants differences; the cranked wings of the EAP have been replaced with a straight delta, the size of the tail plane has been reduced dramatically and the straight intakes of the prototpye have been replaced with a "smiling" configuration.
