- Abstract
- The goal of this Phase 1 program was to evaluate several fire protection schemes with the objective of developing a method of protecting advanced composite drive shafts, such as on the V-22, from any possible exposure to fire or extreme heat. Figure 1 is a schematic of a tilt rotor craft similar to the V-22 Osprey where the threat of fire in the critical drive components area could compromise the performance of the aircraft. This program did successfully evaluate two protection methods, the incorporation of an intumescing agent into the composite piles and a low-density ceramic insulation wrap, that could prevent the shaft from failing due to extreme heat. In addition, these two protection methods could be applicable to a variety of other composite structures.
