Modifications were made to the Avrocar based on tunnel testing results at N.A.S.A. Ames Research Center to improve control systems for hovering, transition, and forward flight.
The modifications included deploying the peripheral jet sheet from the wing tip for transition and forward flight, with changes mainly focused on diverting the annular jet aft for increased thrust and better aerodynamic and control characteristics.
The control system was tested through static and flight tests at Avro and Ames Research Center, with additional terrain tests over various obstacles to demonstrate the vehicle's ability to operate over unprepared terrain.
The Avrocar faced challenges during flight testing due to stability and control issues resulting from the modifications, requiring adjustments to the hovering control system and central jet configuration.
Despite some difficulties like ingestion of low-density material causing engine issues, the Avrocar successfully demonstrated its capability to operate over different terrains, paving the way for further development to increase thrust for vertical takeoff and forward flight transition.
