Abstract : The possibility of utilising the entrained air in a thrust augmenting ejector for thrust control purposes has been 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, have been investigated and results have shown that all systems provide some degree of thrust vector and thrust magnitude control. Maximum TVC in yaw/pitch mode was available with duct swivelling, while radial tabs provided maximum TMC.
