The F-18 High Alpha Research Vehicle: A High-Angle-of-Attack Testbed Aircraft

摘要: The F-18 High Alpha Research Vehicle is the first thrust-vectoring testbed aircraft used to study aerodynamics and maneuvering available in poststall flight regime provide data for validating ground prediction techniques. includes a flexible research control system full instrumentation. capability vehicle at angles of attack up 70 degrees also included. This was modified by adding pitch yaw system. No significant problems occurred during envelope expansion phase program. has demonstrated excellent wing rock region increased rolling performance high attack. Initial pilot reports indicate that desirable although some difficulty judging size timing inputs observed. aircraft, preflight testing tests are described.
