Abstract:

An analysis is presented of some aspects of the full scale wind tunnel tests of the Avrocar vehicle. Methods used to analyze force and pressure data are formulated and results are compared with theory and small scale model tests. Aerodynamically, the performance demonstrated by the first Avrocar vehicle in its initial configuration was disappointing in that a low lift curve slop, a large nose-up pitching moment and insufficient jet vectoring capability precluded flight in free air and in the ground cushion above about 35 mph. Modifications to the aircraft based on these and other test results have been made, the major change being in the redesign of the trailing edge region where a rearwardfacing nozzle, containing a pitch control vane to provide adequate jet vectoring control, has been incorporated. The jet flap effect thus obtained is expected to allow flight in free-air as well as at higher speeds in the ground cushion. Author
