Rotary Balance Data for a Typical Single-Engine General Aviation Design for an Angle-of-Attack Range of 20 to 90 Deg. 3: Influence of Control Deflection on Predicted Model D Spin Modes

摘要

The influence of control deflections on the rotational flow aerodynamics and on predicted spin modes is discussed for a 1/6-scale general aviation airplane model. The model was tested for various control settings at both zero and ten degree sideslip angles. Data were measured, using a rotary balance, over an angle-of-attack range of 30 deg to 90 deg, and for clockwise and counter-clockwise rotations covering an omegab/2V range of 0 to 0.5.
