Abstract

Abstract

The numerical value integral algorithm of aircraft take-off running distance was studied by numerical value calculation theory, and an improvement algorithm was put up.The calculation method of engine instantaneous thrust and take-off aerodynamics data was improved by interpolation method.The liftoff speed was calculated by iteration method.Aircraft take-off running distance calculation was programmed based on the improved algorithm.In order to test the improved algorithm, the take-off running distances of 5 aircrafts were computed when their engine thrust curves were offered.The average error of the former algorithm is 55.6 m, while the one of the improved program is 23.4 m.Furthermore, 12 kinds of take-off running distances of a certain aircraft were computed when its engine thrust curve wasn't offered.The average relative error between computation result and actual running distances is 2.9%.The results indicate that the computation precision of the improved algorithm is higher than the former algorithm.
