摘要

A team of UK experts has successfully flown the first ever large-scale aircraft powered by variable-buoyancy propulsion. The Phoenix uses the concept of variable-buoyancy propulsion already used for underwater remotely-operated-vehicles but which has not previously been used successfully for the propulsion of a large-scale aircraft. The vehicle is designed to repeatedly transition from being lighter-than-air to being heavier-than-air, so that thrust is generated to propel the craft forward. The team behind the Phoenix project includes representatives from academia and industry led by Andrew Rae, Professor of Engineering at the University of the Highlands and Islands. Applications for a variable-buoyancy vehicle could include high-altitude psuedo satellite (HAPS) missions, such as persistent surveillance, communications or science missions.
