gust loads

gust loads

The loads on an aircraft structure caused by vertical gusts, which are calculated in terms of the “equivalent sharp-edged gust.” The airplane is assumed to fly from still air instantaneously into a vertical current equal to the maximum vertical speed of the gust; the buildup of the load on the structure is instantaneous.
