A similarity comparison method of flight test points

Abstract

Civil aircraft flight test has the characteristics of high risk, tight time, and huge cost. How to optimize the flight test task and make it more efficient has become a major concern for major civil aircraft design and manufacturing companies in the world. However, it is difficult to get specific information about related technologies from public references. A similarity comparison method for flight test points was proposed in this paper. The probability of coincidence between different flight test points can be calculated by this method, and the results were used to evaluate the similarity of flight test points, thereby providing a criterion for flight test task optimization. The proposed method was applied to solve a preliminary optimization problem of a flight test task for flight simulator data collection, satisfactory results were obtained. A useful exploration of the digitization and intelligent construction of civil flight test task management system was made also.
