Vulture - Unmanned Aircraft

Defense Advanced Research Projects Agency (DARPA) of United States is working to develop an unmanned aircraft that is able to stay in air for a period of 5 years at a time. It is one of the most recent inventions of world.



Officials of DARPA has revealed that this aircraft will be known as VULTURE due to its Persistent Pseudo-Satellite Capability . It means that this aircraft will be able to fly over a single area, communicating or performing analysis for years at a time.


Even this project looks appealing to many of you, but there are some serious problems or you can say obstacles in achieving this project.



1) First challenge in front of designers is to figure out some Way to Supply Power to this aircraft during long missions.


2) Another problem is that this aircraft will carry a 1000 pound (450 kg) payload in winds at an altitude of 60,000 to 90,000 feet.

3) Designers have also to sort out the problems regarding Deterioration of Materials during their long-time exposure to stratospheric flight.

Network interfaces are assigned a zone to dictate the behavior that the firewall should allow. For computers that might move between networks frequently (like laptops), this kind of flexibility provides a good method of changing your ru...
