A Control System for the Wind Tunnel Model of a Reverse-Blowing Circulation Control Rotor (RB-CCR)

Abstract

A pneumatic valving system has been developed to provide cyclic and collective control inputs for a circulation control type rotor over an advance ratio range of 0 to 2.0. The design method and experimental techniques utilized in developing the control system for a wind tunnel model of the reverse-blowing circulation control rotor (RB-CCR) are discussed and a tradeoff is presented between two control systems which have potential for the necessary requirements. A cam-collector nozzle system is considered a better choice for the model rotor configuration than a cam-collector ring control system. It was concluded that a system to control the RB-CCR wind tunnel model can be designed by employing the proper area relationships and adhering to a simple design procedure.
