Embodiment 1

[0036] A retrievable high-speed flying rocket, comprising a mission load compartment 1, a transition section 2, a rocket body 3, a cabin structure 6, wings 8, a tail section 9, an air rudder system 10, a gas rudder system 11, a landing buffer device 12, Parachute system, airbag system, connection mechanism, radar altimeter; the rocket body includes recovery cabin 4 and main engine 5.

[0037] The task load compartment 1 is in the shape of a lifting body, and the transition section 2 is used to connect the task load compartment 1 and the recovery compartment 4; the recovery compartment 4 is connected to the main engine 5; the nacelle structure 6 Installed on the main engine 5 through the connecting mechanism, the connecting mechanism is a hoop 7 in this embodiment; the wings 8 are installed on both sides of the nacelle structure 6; The main engine 5 is connected to the nacelle structure 6; the air rudder system 10 and the gas rudder system 11 are both used for flight control, a...

Embodiment 2

[0044]The recyclable high-speed flying rocket of this embodiment adopts a single-stage solid engine (ie, the main engine 5), has a symmetrical large lifting surface aerodynamic shape, and has a low-altitude and sharp-turning trajectory to meet the needs of low-altitude and high-speed flight tests. The solid engine is replaced directly after recovery, without maintenance and confirmation work process, which simplifies work and improves product reliability; adopts gliding deceleration and parachute + airbag recovery methods to realize the recovery of accurate landing points of recoverable high-speed flying rockets, reducing the impact on the ground runway The dependence of landing gear and other landing gear improves the adaptability of the recovery system. The task load adopts a unified interface to meet the task load requirements of different dimensions and weights.

Description

technical field [0001] The invention relates to a recoverable high-speed flying rocket and a recovery method, belonging to the technical field of reusable rockets. Background technique [0002] With the continuous development of the aerospace field at home and abroad, how to reduce the cost of space launch is one of the main challenges faced by the entire space industry, especially for some low-altitude high-speed flight test launches, realizing the recovery and reuse of the vehicle and its payload is the key to reduce important measure of cost. Since the middle of the last century, the major aerospace countries in the world have continued to carry out research and experiments on reusable space transportation systems. From the perspective of configuration and technical characteristics, reusable vehicles can be divided into two categories: horizontal recovery and reuse vehicles and vertical recovery and reuse launch vehicles. The premise of conducting research on vertically...
