DARPA (the Defense Advanced Research Projects Agency) has announced a competition for ANCILLARY (AdvaNced airCraft Infrastructure-Less Launch And RecoverY eVTOLs), or electric Vertical Take Off and Landing vehicles.  (That’s about as tortured an acronym as we could cram into a lead paragraph.) The goal, to develop a Class 3 unmanned VTOL aircraft capable of flying all-weather missions from ships or land, has been responded to by several industry leaders.  These have been winnowed to six “finalists” who will craft demonstration models of their respective designs. DARPA’s announcement includes the following: “The UAS would be able to launch and recover from ship flight decks and small austere land locations in adverse weather without additional infrastructure equipment, thus enabling expeditionary deployments. Unlike large VTOL systems, the small UAS size would allow many aircraft to be stored and operated from one ship creating a tactical beyond-line-of-site (BLOS) multi-intelligence sensor network capability.” The Six Finalists Phase Ia of the competition reduced the number of …

QinetiQ, a British aerospace manufacturer, launched its unmanned, solar-powered twin-motored aircaft from the Yuma, Arizona Proving Grounds on July 9, 2010 and landed it today, July 24. According to QinetiQ’s press release, ” Zephyr successfully landed after 14 days (336 hours) and 21 minutes flying over Arizona and is now awaiting official confirmation of its world record status.” http://www.youtube.com/watch?v=CT-DYeEP8dg “An official from the Federation Aeronautique Internationale (FAI), the world air sports federation, has been monitoring progress at the Yuma Proving Ground and when Zephyr is back on the ground he looks set to be able to confirm a number of new world records. This includes quadrupling its own unofficial world record for longest duration unmanned flight (82 hours, 37 minutes set in 2008) and surpassing the current official world record for the longest flight for an unmanned air system (set at 30 hours 24 minutes by Northrop Grumman’s RQ-4A Global Hawk on 22 March 2001). Zephyr will also have flown longer, non-stop …
