Book excerpt: Tests have been conducted to measure the aerodynamic characteristics of a spinning model of a 105mm shell fitted with canard control surfaces. The tests covered an incidence range of -2 deg. to 15 deg., a Mach number range of 0.70 to 0.95, and a control deflection range of zero to 30 deg. The effectiveness of the canards as pitch and yaw controls and for generating manoeuvring forces is discussed. The conclusion is reached that available manoeuvring forces would be small, and an example is given for a typical trajectory in which a maximum shift of 90 m from the unguided impact point could be obtained.
