Low-Cost Approaches to Proving of High-Risk Fast VTOL Designs

A September 1991 industry-government workshop was held under the auspices of the United States Army Research Office. This meeting, together with some subsequent discussions, examined impediments and opportunities relating to new, versatile, high-performance vertical aircraft for Army or other users. It was concluded that the technology elements that could enable free-wheeling yet economical flight proofing of risky design concepts, without jeopardizing human life, are generally available.
