Herbst 机动中的摇滚运动试验研究

A wind tunnel device simulating Herbst maneuver and the related motion/flow synchronous measurement technology are developed. By the device, the roll oscillation of the chined-body configuration undergoing the Herbst maneuver is studied. The device is used to study the roll oscillation of the chined-body configuration during the Herbst maneuver. The main stage form the rolling motion is revealed and the influence of motion parameters on the rolling motion is analyzed. Results show that the roll oscillation in the Herbst maneuver mainly comes from the pitch-up stage, and the conical motion stage has little effect on the rolling motion. In the pitch-up stage, the rolling motion can be divided into the quasi-static region, transition region and sine-like region. As the reduced pitch rate is 0.01, the curves of the rolling motions undergoing pitch up coincide each other before the pitch angle of 50°, and after that pitch angle the curves are dispersed. The reduced pitch rate can be used as a dimensionless parameter for the rolling motion of the chined-forebody configuration undergoing pitch up within a certain range of pitch angle. The rolling motion of the chined-forebody configuration undergoing pitch up within a specific range of pitch angle can be described by the reduced pitch rate, which can be employed as a dimensionless parameter.
