Walrus Hula (Paperback)

High Quality Content by WIKIPEDIA articles The Walrus HULA was a proposed Hybrid Ultra Large Aircraft. The goal was to create an airship capable of traveling up to 12,000 nautical miles (about 22,000km) in range, while carrying 500-1000 tons of cargo. In distinct contrast to earlier generation airships, the Walrus HULA would be a heavier-than-air vehicle and would generate lift through a combination of aerodynamics, thrust vectoring, and gas buoyancy generation and management. As of April 2006, the project was in danger of termination. The 2007 Budget request from DARPA called for the termination of work on WALRUS after completion of the current Phase I contracts.
