An experimental study on aerodynamics of a roll-controllable rocket
Abstract
The rolling motion induced by misalignment of the front fins of a sounding rocket (such as the NASDA TT-500A) and its control via the aerodynamic forces on the tail fins are investigated analytically and experimentally. The results of wind-tunnel tests at freestream Mach numbers 0.5-2.5 and angles of attack 0-8 deg are shown to be in good agreement with the predictions of strip theory and with theoretical simulations, demonstrating the feasibility of this control approach.
