METHOD FOR PREDICTING STABILITY IN STRONG WIND ROTOR START AND STOP

摘要

Provided is a method for predicting stability during rotor start and stop in a strong wind. The method for predicting stability during rotor start and stop in a strong wind includes a step in which one strong wind generating device is used to measure the speed of the strong wind that is reached every time the distance from the strong wind generating device is changed and a range having the same speed; a step in which the number of strong wind generating devices is determined in view of the diameter of a rotor of a test object helicopter so that the strong wind of the same speed can reach the entire rotor of the test object helicopter; a step in which the fixed number of strong wind generating devices are arranged horizontally; a step in which the speed of the strong wind that is reached every time the distances from the arranged strong wind generating devices are changed is measured again; and a step in which the strong wind of the arranged strong wind generating devices is used to perform a rotor start and stop test in the strong wind that is required in helicopter design.
