This is the premise on which the Challenge is based:
"Higher speeds, increased efficiency, elegant designs are the focus of new VTOL X-Plane
One of the greatest challenges of the past half century for aerodynamics engineers has been how to increase the top speeds of aircraft that take off and land vertically without compromising the aircraft's lift to power in hover or its efficiency during long-range flight.
The versatility of helicopters and other vertical take-off and landing (VTOL) aircraft make them ideal for a host of military operations. Currently, only helicopters can maneuver in tight areas, land in unprepared areas, move in all directions, and hover in midair while holding a position. This versatility often makes rotary-wing and other VTOL aircraft the right aerial platform for transporting troops, surveillance operations, special operations and search-and-rescue missions.
Compared to fixed-wing aircraft, helicopters are slower-leaving them more vulnerable to damage from enemy weapons. Special operations that rely on lightning-quick strikes and medical units that transport patients to care facilities need enhanced speed to shorten mission times, increase mission range, reduce the number of refueling events and, most important, reduce exposure to the adversary."
Here is the actual "FedBizOpps" description and LINK: http://www.fbo.gov/i...b=core&_cview=1
"The DARPA Tactical Technology Office is soliciting proposals on the design, development and demonstration of a vertical takeoff and landing (VTOL) experimental aircraft (X-Plane) with exceptional performance in vertical and cruise flight, and operational capability through transition from vertical to forward flight. The purpose of the program is to champion the design and development of sub-system technologies and integrated air vehicle configurations that will enable radical improvements in VTOL flight. The program will demonstrate an aircraft capable of sustained flight at high speeds, improved hover and cruise efficiencies that are significantly greater than contemporary rotary-wing aircraft, and increased useful load fractions and aircraft functionality.
See the attached file "DARPA-BAA-13-19" for the full text of the solicitation. The attached Broad Agency Announcement (BAA) is not a draft and represents the FINAL solicitation for the VTOL X-Plane effort."
It is important to note that Vectored Thrust (such as the Harrier) and "In Wing Rotors" will not meet the requirement - so some serious re-thinking of the whole VTOL concept is required. This is, and always has been, one of the greatest challenges in Aeronautics
I am thinking of a Helium assist descent and take off (NOT Balloons!!)
I really wish MID was still with us (God Rest his Soul) but I know 747-400 is here.
This is a LIVE challenge, are YOU up for it?
