Hybrid Air Vehicles Ltd. is developing the SkyCat, a new class of lighter-than-air vehicles which are highly maneuverable using ducted fans, and able to take off and land vertically on any surface. HAV envisions designs with up to 1,000 tons payload for strategic airlift, humanitarian rescue, and service in the oil and gas industries.
HAV recently won a major role in a $500 million contract with the US Army, partnering with Northrop-Grumman to develop the LEMV (Long Endurance Multi intelligence Vehicle), a long-duration surveillance platform.
Rocketeer comments: I note that the projected dimensions of the internal payload bay on the SkyCat 200 are almost large enough to accommodate an assembled Falcon-9 stack including payload. One could envision a modified SkyCat capable of carrying two EELV-class stacks underslung side by side. The vehicle would pick them up from the assembly plant, fly to the launch site, and lower them directly onto launch erectors.
CUTE (Cranfield University Titan Explorer) was a multiprobe mission to Titan including aerobots and landers, designed by MSc students in Astronautics and Space Engineering at Cranfield University in 2009.
