Embodiment Construction

[0045] Attached below Figure 1-5 And examples illustrate the present invention in detail.

[0046] A desktop hardware-in-the-loop simulation device for hypersonic vehicle navigation guidance control system, such as figure 1 As shown, it is composed of six parts: guidance assembly, steering gear, power supply, simulation computing lower computer (abbreviated as lower computer), simulation computer upper computer (abbreviated as upper computer) and ground test control computer. Among them, the guidance assembly is connected with the lower computer of the simulator and the test control computer through a serial port to form a closed real-time simulation loop; at the same time, the upper computer of the simulator and the lower computer are connected through a network cable to realize the control and test of the lower computer.

[0047] The data display and recording functions of the present invention are respectively realized by the ground measurement and launch control computer...

Abstract

The invention discloses a semi-physical simulation system and method of a hypersonic flight vehicle navigation and control system. The system comprise a guidance combination body, a steering engine, apower supply, an upper computer, a lower computer and a test control computer; before the simulation is started, the upper computer establishes a flight simulation model according to a current simulation object, and is compiled and downloaded to the lower computer; and the guidance combination body is initialized. During simulation, the test control computer sends a launching instruction to the lower computer and the guidance combination body; the lower computer performs flight simulation calculation after being controlled by the launch instruction, so that the aircraft attitude and positioninformation at the current moment are obtained and sent to the guidance combination body; the guidance combination body conducts navigation and control calculation according to a time-of-flight sequence after receiving the launching instruction, a control instruction of the steering engine is obtained, then the steering engine is controlled to deflect, the actual position and the control instruction of a rudder shaft are sent to the lower computer, and closed-loop simulation is achieved; and meanwhile, the rudder shaft information and the navigation control result information are sent to the test control computer. After the simulation is finished, precision analysis is carried out.

Description

technical field [0001] The invention relates to a hypersonic aircraft control system simulation technology device, in particular to a desktop semi-physical simulation technology device for a hypersonic aircraft navigation, guidance and control integrated system, belonging to the technical field of hypersonic aircraft navigation and control. Background technique [0002] Hypersonic aircraft refers to aircraft with a flight speed higher than 5 times the speed of sound. Hypersonic aircraft technology is the highest and newest aircraft technology, which is of great engineering significance for improving national defense technology and enhancing civilian access to space.
