Research on Test Aircraft Quantitative Analysis Model during Flight Test Planning

Abstract

The process of civil aircraft development is a complex system, where flight test is an extremely important process of the project. In the top-level planning of flight test, it is particularly important to determine the quantity of test aircraft, which is closely related to the total flight test period, cost, and resources. This paper analyzes and studies the number of test aircraft performing flight test missions, analyzes the related factors of the number of test aircraft, and proposes a reasonable calculation model with engineering operability based on flight test period and cost. It provides numerical data reference for overall planning of civil aircraft flight test during multi-objective optimization.
