Abstract

The invention relates to the technical field of aircraft design and especially relates to an aircraft effectiveness sensitivity analysis method. The aircraft effectiveness sensitivity analysis method comprises following steps: 1. establishing a preset operational effectiveness requirement set of different air combat superiorities; 2. establishing a combat tactics set corresponding to the different requirements in the preset operational effectiveness requirement set; 3. performing large sample optimization on aircraft tactical index values to obtain an optimized interval of the aircraft tactical index values; step 3 comprises following steps: 3.1 setting an initial aircraft tactical index value as simulation input; 3.2 using the combat tactics set as a simulation scheme to carry out simulation experiment; 3.3 using the preset operational effectiveness requirement set as the evaluation criteria of simulation results. By means of the tactical index effectiveness sensitivity analysis method of the invention, aircraft optimized design is guided and combat effectiveness is increased, the related cost of development stages is reduced and technical risk is reduced.

Description

technical field [0001] The invention relates to the technical field of aircraft design, in particular to an aircraft performance sensitivity analysis method. Background technique [0002] Aircraft combat effectiveness (referred to as "efficiency") research is a very important overall specialty in aircraft research and development. Each node of the aircraft's full life cycle must also meet the constraints of combat effectiveness indicators, and the combat effectiveness professionals will participate in the evaluation and review. With the requirements of future aircraft design, combat effectiveness majors will take on more challenging tasks, no longer just a situation of "combat effectiveness evaluation", but will shift from the back-end work of the task chain of "analysis + evaluation" to "asking questions + The front-end work of the "combat effect design" task chain has been fully expanded. [0003] At present, there is still a huge gap between the research level of combat...
