Flight-tests of NASA's McDonnell Douglas F-18 High Alpha Research Vehicle (HARV), with experimental nose strakes for yaw control, are due to begin on around, 24 May.
The conformal vortex flow-control strakes will be used both in conjunction with, and without, the HARV's thrust-vectoring system, to assess yaw control at high angles of attack. Better pointing ability is seen as being essential to the successful tactical use of post-stall manoeuvring in air-to-air combat.
