The possibility of utilizing the entrained secondary air in a thrust augmenting ejector for thrust control purposes was examined in a series of experiments using high pressure unheated air as the primary jet. Four control concepts, namely duct venting, axially deployed spoilers, radially deployed tabs and duct swivelling, were investigated and results have shown that all systems provide some degree of thrust vector and thrust magnitude control. Maximum Thrust Vector Control (TVC) in yaw/pitch mode was available with duct swivelling, while radial tabs provided maximum Thrust Magnitude Control (TMC).
