| Keywords: F-8EFN Prototype NAN5-64.jpg The prototype for the French Vought F-8E FN Crusader This aircraft was originally a U S Navy F-8D BuNo 147036 which was used as the test airframe It flew for the first time on 27 February 1964 but already crashed on 11 April 1964 The first production F-8E FN flew on 26 June 1964 and this aircraft was then assigned the task of completing the test program The F-8E FN had to be modified so that it could operate safely aboard French aircraft carriers Foch and Clemenceau In order to reduce the approach speed the maximum angle of incidence of the variable-incidence wing was increased from five to seven degrees The drooping wing leading edges were separated into two sections in order to increase the amount of camber that could be achieved when they were extended A boundary layer control system was added which blew pressurized air from the engine compressor through adjustable air vents that exhausted over the trailing edge wing flaps The airflow pressure automatically increased with the angle of flap deflection The maximum angle of deflection of the trailing-edge flaps was increased The surface area of the tailplane was increased The aircraft was also equipped with an AN/APQ-104 radar to guide French radar-guided Matra R530 missiles <br>Original caption Prototype F-8E FN Crusader which tested new features of the F-8E's which Ling-Temco-Vought built for the French Navy made its first flight on February 27 The plane shown here taxiing out for its initial flight was flown by Test Pilot Robert Rostine Major differences between the French Crusader and the standard F-8E built for the US Navy are in the wing These provide slower landing and takeoff speeds to permit operation from smaller French Carriers The wing has two degrees less angle of incident in the French plane when in the up position It also incorporates double droop leading edges on the wings and boundary layer air blown over the ailerons which will droop to 40 degrees double that of the U S versions The double-drooop feature was used in the F8U-3 Crusader U S Navy Naval Aviation News May 1964 http //www history navy mil/nan/backissues/1960s/1964/May64 pdf; http //collections naval aviation museum/emuwebdoncoms/pages/doncoms/AdvQuery php U S Navy National Museum of Naval Aviation photo No http //collections naval aviation museum/emuwebdoncoms/pages/doncoms/Display php irn 47918 QueryPage 2Femuwebdoncoms 2Fpages 2Fdoncoms 2FAdvQuery php 1996 253 7360 007 1964-02-27 USN PD-USGov-Military-Navy F-8 Crusader in service with France | ||||
