Abstract

The invention belongs to the field of overall design of single-stage injection aerospace vehicles, and particularly relates to an aerospace vehicle mass estimation method. Comprising the steps of 1, obtaining a general equation of an aircraft acceleration process; 2, constructing a mass ratio estimation model of a rocket propulsion mode according to the general equation of the aircraft acceleration process; 3, according to the general equation of the aircraft acceleration process and the mass ratio estimation model of the rocket propulsion mode, constructing a mass ratio estimation model of an air-breathing propulsion mode; and 4, constructing a mass estimation model of the single-stage injection aerospace vehicle according to the mass ratio estimation model of the rocket propulsion mode and the mass ratio estimation model of the air-breathing propulsion mode. According to the method, estimation of the total mass of the single-stage injection aerospace vehicle is completed, the dynamic mode conversion point, the aircraft structure mass fraction, the law between the injection load and the total mass of the aircraft can be rapidly obtained, and the convergence speed of the scheme is increased.

Description

technical field [0001] The present application belongs to the field of overall design of a single-stage orbital aerospace vehicle, and particularly relates to a method for estimating the mass of an aerospace vehicle. Background technique [0002] A single-stage orbital aerospace vehicle is a reusable space-to-earth shuttle vehicle used to deliver orbital loads into orbital space. At present, there is still a lack of research on conceptual design methods suitable for single-stage orbiting vehicles at home and abroad, let alone a realistic single-stage orbiting vehicle for reference. The research work on the single-stage orbiting aerospace vehicle scheme mainly focuses on the scale evaluation of the whole system and the selection of aerodynamic layout. In the aspect of aircraft quality assessment research, the research work that has been carried out is mainly divided into two categories: one is to obtain the relationship between the size and mass of the aircraft through the s...
