Aircraft is a vehicle that can fly by being supported by the air. But have you seen an unmanned aerial vehicle that can be able to stay in the air for five years at a time? It is known as Vulture as a Pseudo-Satellite, one of the recent inventions of world.
Defense Advanced Research Projects Agency (DARPA) of United States headed by Daniel Newman is working to develop an unmanned aerial vehicle. It is known as Vulture due to its persistent pseudo-satellite capability in an aircraft package which means that this aircraft will be able to fly over a single area, communicating or performing analysis for years without refueling or any other maintenance at a time.
While developing this project the company encounters serious problems or you may say an obstacle. One of the major obstacles is how would the designer figure out the way to supply power to such an aircraft during the long missions. Second, the aircraft will carry a 1000 pound (450 kg) payload in winds at an altitude of 60,000 to 90,000 feet. In addition to this, the designer has also to sort out the problems regarding Deterioration of Materials during their long-time exposure to stratospheric flight.
Vulture will be used as a surveillance and communications aircraft, which can be repositioned on an area of interest. It operates in the stratosphere and not on the Earth's orbit. This would provide a 65 dB upgrading in communications capability and will increase onboard sensor resolution.
