Ballistic design method and system for multi-light source laser aircraft

Abstract

The invention provides a ballistic design method and system for a multi-light source laser aircraft, which is applied to a target laser aircraft. The target laser aircraft is a laser aircraft that provides at least two light sources with laser beams, and the model of the target laser aircraft is a Myrabo light boat configuration; the method; Including: determining the structural model parameters of the target laser aircraft; determining the position information of the light source that provides the laser beam for the target laser aircraft, and determining the initial pitch angle of the target laser aircraft; based on the structural model parameters, calculating the dynamic model of the target laser aircraft during the acceleration process parameters, and calculate the aerodynamic parameters of the target laser aircraft in the air-breathing mode; based on the position information of the light source, dynamic model parameters, aerodynamic parameters and initial pitch angle, the ballistic calculation of the target laser aircraft is performed. The invention alleviates the technical problem that the ballistic design method of the traditional chemical powered launch vehicle in the prior art is not suitable for the ballistic design of the multi-light source laser aircraft.

Description

technical field [0001] The invention relates to the technical field of laser aircraft, in particular to a ballistic 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 a power source, so that the laser aircraft can generate thrust to complete the satellite launch mission. [0003] The launch plan of the laser aircraft involves multi-disciplinary design of structure, power, aerodynamics and ballistics. There are few ballistic design methods related to domestic laser aircraft, most of which are single-ground-based laser station design, and most of the existing design methods are to design and integrate each discipline separately. The coupling variables existing between disciplines require multiple iterations, and the time cost is relatively high. Large, it is inconvenient to optimize the overall ...

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
