Rocket for realizing gliding range extension and accurate control by adopting coiled arc wings

Abstract

The invention discloses a rocket overall scheme for realizing gliding range extension and accurate control by utilizing a control cabin section, and realizes range extension and accurate control of a drop point. The control cabin section is additionally arranged in the middle of a rocket, a pair of coiled arc type lift wings which can be folded and unfolded and have reverse installation offset angles can generate aerodynamic force in the direction perpendicular to the wing surface in flight, the direction of the aerodynamic force is controlled by controlling the rolling angle of a wing seat of the control cabin section relative to a ground coordinate system, and range extension of the rocket and accurate control of the drop point are realized; and a pair of coiled arc type anti-rotation wings which can be folded and unfolded and has same-direction installation offset angles provides rotation reduction torque, and rotation reduction of the wing seat of the control cabin section and balance of control torque of a control motor of the control cabin section are realized. The lift wings and the anti-rotation wings in a coiled arc form are adopted, so that the pneumatic shaping effect of the rocket in a folded state and an unfolded state is effectively improved, and the flight resistance can be reduced to the maximum extent. According to the rocket overall scheme, accurate control of the drop point is realized on the basis that the flight distance is effectively increased.

AI Technical Summary

Problems solved by technology

[0005] Traditional gliding range-extending rockets mainly control the gliding range-extending by using steering gears with different aerodynamic layouts. The structure and control mechanism of the rocket are relatively complicated, and the general gliding range-extending and the precise control of the landing point cannot be realized by a single control method, which greatly increases the structure. Mass and Structural Complexity

On the other hand, due to the change of the aerodynamic layout of the traditional gliding extended range rocket, it is not suitable for the information transformation of the traditional stock uncontrolled rocket

[0006] Since the design of the rocket needs to meet the size constraints of the launch platform, under the limited envelope size constraints, the lift-to-drag ratio during the flight of the rocket should be maximized to achieve a better gliding range extension effect, which restricts the gliding to a certain extent. The development of extended-range rockets
