Multi-light-source laser aircraft trajectory design method and system

Abstract

The invention provides a multi-light-source laser aircraft trajectory design method and system which are applied to a target laser aircraft. The target laser aircraft is a laser aircraft providing laser beams for at least two light sources, and the model of the target laser aircraft is a Myrabo light ship configuration. The method comprises the steps of determining structure model parameters of a target laser aircraft; determining position information of a light source for providing a laser beam for the target laser aircraft, and determining an initial pitch angle of the target laser aircraft; based on the structural model parameters, calculating dynamic model parameters of the target laser aircraft in an acceleration process, and calculating aerodynamic parameters of the target laser aircraft in an air suction mode; and performing trajectory calculation on the target laser aircraft based on the position information of the light source, the dynamic model parameters, the aerodynamic parameters and the initial pitch angle. The technical problem that in the prior art, a trajectory design method of a traditional chemical power carrier rocket is not suitable for trajectory design of a multi-light-source laser aircraft is solved.

Description

technical field [0001] The invention relates to the technical field of laser aircraft, in particular to a trajectory design method and system for a multi-light source laser aircraft. Background technique [0002] Laser propulsion is a new type of aircraft propulsion technology, which can use the laser beam emitted by the ground laser base station as the power source, so that the laser aircraft can generate thrust to complete the mission of satellite launch into orbit. [0003] The launch plan of laser aircraft involves multidisciplinary design such as structure, power, aerodynamics, and ballistics. There are few ballistic design methods related to domestic laser aircraft, most of which are single-ground laser station design, and most of the existing design methods are to design and integrate each discipline separately. The coupling variables between disciplines need to be iterated multiple times, and the time cost is relatively high Large, inconvenient for overall design op...

Problems solved by technology

There are few ballistic design methods related to domestic laser aircraft, most of which are single-ground laser station design, and most of the existing design methods are to design and integrate each discipline separately. The coupling variables between disciplines need to be iterated multiple times, and the time cost is relatively high Large, inconvenient for overall design optimization

[0004] Since the way of laser propulsion to generate thrust is different from that of traditional chemical propulsion (the laser beam is provided by the laser source to act on the working medium to generate thrust), the special requirement for the laser incident angle (the angle between the laser beam and the axis of the laser aircraft) to be zero makes The ballistic design method of traditional chemical launch vehicle is not suitable for the ballistic design of target laser vehicle
