Fixed Wing VTOL UAV - StealthOsprey

Fixed Wing VTOL UAV - 100 Km Range

Fixed Wing VTOL UAV (as opposed to ‘multi-rotor’, i.e. helicopters) use a wing like a normal aeroplane to provide the lift and has vertical lift rotors. Because of this they only need to use energy to move forward, not hold themselves up in the air, so are much more efficient.

For this reason they are able to cover longer distances, map much larger areas, and loiter for long times monitoring their point of interest. In addition to the greater efficiency, it is also possible to use gas engines as their power source, and with the greater energy density of fuel many fixed-wing VTOL UAVs can stay aloft for 16 hours or more.

The main downside of a fixed-wing aircraft is obviously their inability to hover in one spot, which rules them out for any general aerial photography work. This also makes launching and landing them a lot trickier, as depending on their size you can need a runway or catapult launcher to get them into the air, and either a runway, parachute or net to recover them safely again at the end. However our new Fixed Wing VTOL UAV solves all of the issues.
