Patent ID: 7350746

Claim:
Aircraft with aerostatic lift, comprising a structure, which includes at least two non-rigid spindle-shaped elements side by side ( 11 ), joined by at least one connecting element ( 12 ), said aircraft also being provided with a movement and attitude control system with a set of several electric motors, of which at least one is adjustable with rotation around an axis perpendicular to the rotation axis of said motor, each of which drives a propeller ( 13 ) with fixed or variable pitch, wherein at least one of the propellers ( 13 ) is mounted on a vertical arm ( 14 ) extending from the connecting element ( 12 ) and disposed at a distance from the whole body centre of gravity, and wherein the aircraft consists of an airship ( 10 ), which can be piloted or radio-controlled, without deflecting aerodynamic control surfaces and sustained by helium, said movement and attitude control system being solely of the propulsive type, with a ballonets system wherein for each hull during the climbing phase, ballonets deflate progressively, from the outer to the central sector and during the descent phase, ballonets inflate progressively from the central to the outer sectors.
