Trimming Aircraft on the Ground Based on the Hybrid Genetic Algorithm

概要

Trimming aircraft on the ground is an absolutely necessary for flight simulators. In order to carry out this task, the aircraft-runway dynamic model is analyzed, and then an elite re-optimized hybrid genetic algorithm for trimming the model is designed, which combines the merits of a genetic algorithm and pattern search. It does not only avoid being trapped by a local optimum, but also improves the precision of results and saves on the time for trimming. Because this trim method requires only in-out information of the dynamic model, it is a universal tool and can be used on different trim works of different simulated aircraft. Its efficiency is then validated in a flight simulator, which reveals its engineering significance.
