| Abstract: | Back airbrake failures, such as beam fracture, skin crack, etc., due to vibration in the operation of a certain combat aircraft occurred frequently. A design analysis has resulted in an improved anti-vibration fatigue, holed, T-profile reinforced structure. Satisfactory results have been obtained from a flight test. The anti-vibration damage design philosophy and technique for the back airbrakes are presented in this paper. |
