A UAV HELICO, WHY?

The helicopter is the aircraft which has the most complete flight envelope. As a monitoring UAV, it is the unique aerial vehicle, capable of accomplishing a task being in stationary flight, possessing nevertheless enough of dynamism to be able to move fast.

Whirling winds issue

One of the biggest advantages of a machine with rotary wings (helicopter for example) is its little sensibility to the whirling winds, which can be very strong in urban area or close to the works of art.

It is clear that in such conditions neither plane nor dirigible can be used. It is necessary to employ a machine with stationary flight which would have enough dynamism in order to quickly respond in the case of a violent wind. Only the rotary wings principle combines these two requirements, that’s why our UAV Eyesfly is inspired by the helicopter.

A particular choice: inverted rotary wings

Despite the UAV Eyesfly was inspired from the helicopter, it does not have one of its major disadvantages: tail rotor. Having chosen two inverted rotors, the tail was removed, what makes the machine much compacter (it gave to the machine a purely circular structure).

The inverted structure of the UAV Eyesfly represents originality in comparison with all its competitors: it is not built around an axle but around a cylinder, what allows to clear the internal volume in the center of the UAV (the volume which can hold the client’s payload).
