Thrown type anti-stabilizing wing mechanism for sounding rocket

Abstract

The invention relates to a thrown type anti-stabilizing wing mechanism for a sounding rocket and belongs to the technical field of sounding rockets. The anti-stabilizing wing mechanism comprises a pinpushing device, a nut, an airfoil and a spring. The airfoil is fixedly installed on the outer wall of a sounding rocket body through the pin pushing device and the nut. The spring is put between theairfoil and the rocket body in a compressed state. Under control of a time schedule controller of the sounding rocket, the pin pushing device pushes out a hinge pin and the nut, and the airfoil is separated from a rocket body under the thrust action of the spring. Through the anti-stabilizing wing mechanism, the static stability level of the sounding rocket at the flight low-speed stage can be lowered effectively, and thus the influence of environmental wind on the rocket initial stage is reduced greatly. The anti-stabilizing wing mechanism is thrown away after the flight to preset time, thusthe sounding rocket recovers to the original aerodynamic configuration state, stability of the flight process of the sounding rocket is ensured, and precise control over a sounding rocket trajectory is achieved.

Description

technical field [0001] The invention relates to a throwable anti-stabilizer mechanism of a sounding rocket, which belongs to the technical field of sounding rockets. Background technique [0002] Sounding rockets are mostly uncontrolled rockets, and the trajectory of the rocket (especially the flight trajectory of the active section) is greatly affected by the ambient wind. In the case of wind, the position vector and velocity vector of the end point of the active section of the rocket will deviate from the nominal value. value. [0003] "Sounding Rocket Design" (Aerospace Press, first edition in December 1993) introduces that by adjusting the rocket launch elevation angle and launch azimuth angle, the velocity direction at the end of the active section is compensated for the influence of the actual wind field. "Sounding Rocket Wind Field Compensation and Equivalent Ballistic Wind Conversion" (Journal of National University of Defense Technology, 2000, Vol. 22, No. 6) intro...
