Abstract

One of the factors that greatly affects the flight safety of airships is weather conditions and in particular, discrete gust with a speed equivalent to the speed of the airship. This article presented a method of numerical simulation of discrete gust according to flight safety standards. The discrete gust is considered from the bottom up with velocity in two forms: rectangular velocity distribution and variable velocity as a function of cosin. Research shows that in order for the velocity distribution to be most similar to the flight safety standards, it is recommended to choose a calculated area of size 25L × 10L × 2.5L. This simulation method can be used to study other discrete gust according to flight safety standards in the actual operation of airships.
