EXPERIMENTAL-STUDY OF TAIL-SPAN EFFECTS ON A CANARD-CONTROLLED MISSILE

An experimental investigation was conducted on a cruciform canard-cont rolled missile configuration to determine the effects of tail span/can ard span ratio on controllability. The investigation was conducted at Mach numbers from 1.75 to 3.50. Reductions of tail span/canard span ra tio produced lower static margins and higher trim angle of attack. Res ults show that canard controls can provide pitch and yaw control as we ll as roll control by proper selection of the tail span/canard span ra tio.
