| Abstract: | Acceleration measurements in gusty air have been accumulated over a period of years in order to determine the loads to which airplanes may be subjected. Most of these data have been obtained with the V-G recorders that have been installed in Army, Navy, and commercial airplanes. Theoretical studies of the load variation while flying through various types of gusts have indicated that the effective gust velocities, as obtained from the V-G records, must be supplemented by data on gust gradients. Consequently, some tests have been made on two airplanes, the Martin XBM-1 and the Aeronca C-2N, in gusty air to gain some information of the gradients to be expected. Although the number of flying hours in these tests is small as compared with the V-G total, they were sufficient to indicate that the critical gust gradient depended upon airplane size, a factor which had been given no particular consideration at that time. |
