2.75-Inch FFAR Large Yaw Dynamics

Abstract

Dynamic tests were conducted in the 24-inch Subsonic Wind Tunnel at the Notre Dame Aero-Space Department to investigate primarily the large yaw dynamic characteristics of the 2.75-inch FFAR, utilizing a unique model support system which provides single degree of freedom motion. From the free pitching motion the stability coefficients were obtained for the 2.75-inch FFAR at low subsonic Mach numbers, and at angles of attack up to 60 degrees by fitting the motion to the Linear Theory utilizing the Method of Differential Corrections. Nonlinear effects due to variations in free oscillation frequency are considered. Static test results are also included from tests conducted at the Arnold Engineering Development Center.
