Two-stage injection aircraft back rapid separation device and method

Abstract

The invention discloses a two-stage injection aircraft back rapid separation device and method, and the device comprises a jet flow generator which is formed on a carrier aircraft and is used for providing upward jet flow for a separation surface of a secondary aircraft connected with the carrier aircraft so as to offset partial gravity of the second-stage aircraft. The device can provide upward jet flow for the secondary aircraft to form upward thrust, so that the secondary aircraft can rotate relative to the carrier aircraft to do head-up motion to form a first target inclination angle, the pitch angle of the secondary aircraft is increased, the local attack angle is increased, and lift force generated by the secondary aircraft is rapidly increased, and thus, the secondary aircraft can quickly rise to a certain height to avoid collision with the empennage of the aerial carrier. The jet flow generator does not have complex mechanical motion during working, so that the starting speed is high, jet flow can be provided for the secondary aircraft after starting, and the time required for the secondary aircraft to reach the safe height can be greatly shortened.

Description

technical field [0001] The invention relates to the technical field of separation of two-stage orbiting aircraft, in particular to a rapid separation device and method for the back of a two-stage orbiting aircraft. Background technique [0002] The two-stage orbiter is a reusable space shuttle tool in the future. The carrier aircraft carries the second-stage aircraft (launch vehicle, space shuttle, orbiter, etc.) to a certain height and separates at a certain speed, and then the orbiter accelerates. Climb into orbit, and the carrier plane lands horizontally. The two-stage orbit vehicle provides a low-cost, high-reliability, and high-flexibility solution for future space launches. During the launch process, the separation technology of the carrier aircraft and the secondary aircraft is the key to the success of the launch. [0003] During the separation process, there is a strong aerodynamic interference between the carrier aircraft and the secondary aircraft, which is mani...

AI Technical Summary

Problems solved by technology

[0004] The patent document with the application number 201921714836.2 records the "two-stage orbital aircraft back separation device". Although this device can solve the above problems, the jacking mechanism it uses has a complicated structure, a large additional weight, and requires more energy. During the separation process, the jacking mechanism will generate large aerodynamic resistance and aerodynamic heating, which makes the overall design of the carrier aircraft and the realization of flight engineering more difficult

In addition, the process of jacking up and separating takes a long time, and the rapid separation of the carrier aircraft and the back of the secondary aircraft cannot be achieved
