Abstract

The B-1 vertical stabilizer has been redesigned taking advantage of the unique properties of advanced composite materials to realize weight as well as cost savings. The advanced composite vertical stabilizer has been designed to meet all of the physical and functional-interfaces as well as the service environment. The more significant design trade studies leading to selection of the final structural configuration and testing to verify structural integrity are discussed. Evolution of the tooling required to fabricate the advanced composite substructure is presented, beginning with the original concept and rationale for selection. Various refinements which have been initiated either to improve the producibility of the composite parts or increase the longevity of the tooling are also discussed.
