Some would appear to be out of this world, but a number of them will undoubtedly make it to operational status. Without a doubt, there will be many more proposals and studies of new UAVs in the first decade of the 21 st century. Many, of course, will never make it beyond the paper design phase, while others might reach the prototype stage, and a miniscule percentage will make it to operational status. A number of the more prominent efforts are covered here: USA Future Micro UAV Concepts/Systems Background The UAVs that fall under this category could be the wildest, and demonstrate the highest technologies of any of the many different concepts that are being investigated.
The jet engine intake was located far forward on the fuselage. Finally, the low-mounted main wing was a delta design. The concept also considered the carrying of either 500 or 1,000 pound JDAM munitions. In March 2001, the fog cleared as to the configuration of the Northrop version of the Navy UCAV. The Pegasus was certainly quite different from the earlier configurations con- sidered. From the top view, the UCAV appears kite-like with a rear width of about 27 feet and a length of a similar dimension.
As the speed continues to increase, the jet exhaust valve begins to open, with a majority of the craft's weight now being borne by the canard surface and the tail. When a speed of about 150 miles per hour is reached, the rotor is brought to a stop in a normal wing position perpendicular to the fuselage. Its maximum top speed is estimated to be about 375 knots. There is also the possibility that the UAV could be used to escort manned aircraft, such as the V-22 Osprey. Whether the Dragon Fly, or some variant of the UAV, will ever reach operational status is uncertain.
