Test flight task planning and data playback method and system based on STK design

Abstract

The invention relates to a test flight task planning and data playback method and system based on STK design, and belongs to the field of system simulation research. The method comprises the followingsteps: loading test area terrain and texture data of a to-be-tested aircraft from a scene environment database, and configuring local hydrological environment, electromagnetic environment and atmospheric environment parameters; completing configuration of parameters of the aircraft to be tested and parameters of the load sensor, and configuring trajectory and attitude data of the aircraft to be tested according to two conditions of task planning and data playback; executing simulation operation on the to-be-tested aircraft model configured with the parameters and tasks, viewing position and attitude information in the simulation process from the scene in the simulation process, and controlling the simulation process; and analyzing the relative position, oil consumption, sensor visibilityand communication condition of the aircraft in the flight process, and outputting a simulation result report.

Description

technical field [0001] The invention relates to a method and system for flight test mission planning and data playback based on STK design, belonging to the field of system simulation research. Background technique [0002] As a costly and risky project, flight test needs to fully consider the flight test site, weather conditions, flight critical envelope and other factors. This therefore imposes strict requirements on the planning of the flight mission. However, due to many coupling factors, flight test is a systematic project, and it is very difficult to plan the test flight task by mathematical calculation method, and the workload is too large. The stage puts forward indicator requirements, but lacks the ability to visualize task planning. [0003] STK (Satellite Tool Kit, Satellite Simulation Toolkit) is a leading commercial analysis software in the aerospace field. At the heart of STK is a geometry engine that is used to determine the temporal dynamic position and po...

Problems solved by technology

[0004] However, due to the relatively large functions of the STK software, the software volume is large only for the purpose of flight test mission planning, the learning cost for designers is high, and it also lacks the ability to template and quickly plan flight test missions; on the other hand, STK software does not support The import of airborne test flight data lacks the ability to replay and re-analyze real data
