aircraft speed, fuel consumption data.
The data simulation unit 20 comprises a plurality of data pre-simulation modules 201 for simulating the flight condition data of the aircraft in the space environment according to the original data, wherein the output ends of the plurality of data pre-simulation modules 201 are connected with an aircraft condition prediction module 202, the aircraft condition prediction module 202 predicts the actual flight condition of the simulated aircraft in the space environment according to the flight condition data, and the specific state information of the aircraft when the aircraft is sailed in the space environment can be simulated according to the space environment information and the aircraft state information acquired by the environment acquisition module 101 and the aircraft state acquisition module 102, so that the simulation prediction of the flight condition of the aircraft in the space environment is realized; the simulation prediction of the aircraft in the space environment is obtained by taking a plurality of groups of original data as a reference, namely, the simulation is performed by referring to the information of the original data, and the simulation prediction situation is attached to the flight state of the aircraft when the aircraft actually sails in the space environment; wherein, for the case of simulating and predicting the actual operation of the aircraft in the space environment.
Next, the aircraft condition prediction module 202 predicts the aircraft flight condition by an interval prediction algorithm, which is as follows:
；
wherein ,Pfor the range of travel of the aircraft,xthe above prediction determination of the fuel consumption of the aircraft is performed for the fuel consumption, and the aircraft speed is determined according to the space environment, for example: when the aircraft judges that the obstacle exists in the flight track in the flight process, the navigation speed of the aircraft is reduced, the offset heading is changed, the reduction of the speed of the aircraft can be judged according to 8km/s, and further, the prediction analysis of the flight condition of the aircraft in the space environment is realized.
The avoidance analysis unit 30 performs analysis of: the avoidance analysis unit 30 comprises an abnormal environment analysis module 301 for acquiring space garbage information in a space environment, and the abnormal environment analysis module 301 establishes space garbage position coordinates, the output end of the abnormal environment analysis module 301 is connected with an avoidance path generation module 302, the avoidance path generation module 302 is used for generating an aircraft avoidance travel route according to the space garbage position coordinates, the avoidance travel route takes an aircraft starting point and a destination as standards, a route deviating from the space garbage is planned between the avoidance travel route and the avoidance travel route through the avoidance path generation module 302, and when the avoidance travel route is formed, the aircraft sails in the space environment according to the calibrated avoidance travel route, so that accidents caused by accidental collision of the aircraft sailing in the space environment can be reduced through the acquired space garbage position coordinates, and the simulation of the real sailing scene of the aircraft in the space environment is facilitated.
Since the generated evasive route is a route that the aircraft gives and risks low for the presence of space debris in the space environment for the actual course of the aircraft in the space environment, but since the scenes in the space environment are not controllable, a series of effects resulting from collisions of the aircraft with space debris in the space environment are simulated accurately, and countermeasures are taken after the collisions:
when the position coordinates of the space garbage are determined, the position coordinates of the space garbage are changed to simulate the collision scene of the aircraft and the space garbage, and the output end of the avoidance path generation module 302 is connected with the route control module 303 for changing the avoidance travel route when the aircraft collides with the space garbage, namely, the position coordinates of the space garbage are deviated into the avoidance travel route by changing the position coordinates of the space garbage in the space environment, so that the collision scene of the aircraft and the space garbage is simulated, the direction track deviated by the aircraft and the space garbage can be simulated, the coordinate range deviated when the aircraft collides with the space garbage is judged due to the small resistance of the space environment, and a plurality of avoidance travel routes exist for the aircraft and the avoidance travel route, so that the route control module 303 can make the other avoidance travel routes collide according to the deviation coordinate range caused by the collision of the simulated aircraft and the space garbage, and the route control module 303 can redetermine the travel routes of the other aircraft so as to avoid the influence of the avoidance travel route on the following aircraft on the avoidance travel route caused by the collision of the aircraft in the space environment and the avoidance travel route;
