| Abstract: | Frequent occurrence of failures in the back airbrakes of a type of aircraft, such as beam fracture, skin crack, etc., during their use in the air force had resulted in a modified back airbrake structure. The modified airbrake with holes and additional shapes has proved to be useful in flight test. In order to define the operational life of the modified structure, a vibration comparison test of the original and modified ones has been conducted. This paper presents the ground vibration test of the back airbrakes. |
