Abstract
There is described an aircraft configured to be able to hover, comprising a fuselage; and a support element adapted to support a load, made of elastically deformable material and constrained to said fuselage; the support element being movable in an operating position in which it is arranged at least partially outside said fuselage and supports said load; the aircraft comprises a sock surrounding the support element arranged in said operating position; the sock is configured to contain the elastic return of the support element, in case the support element arranged in said operating position is sheared off.
Claims6
An aircraft comprising:
- a fuselage;
- a rotor assembly configured to permit the aircraft to hover;
- and
- a support element adapted to support a load, made of elastically deformable material and constrained to said fuselage;
- said support element being movable in at least one operating position in which it is arranged at least partially outside said fuselage and supports said load;
- said support element being a rope comprising first ends opposite to each other and directly connected one to a first connector connected to said fuselage and the other one to a second connector connected to said load, so as to maintain said load at a fixed distance from said fuselage when said rope is arranged in the at least one operating position;
- said aircraft further comprising a sock surrounding said support element, when said support element is arranged, in use, in said at least one operating position;
- wherein said sock comprises, in turn, second ends opposite to each other and directly connected one to said first connector and the other one to said second connector independently of the respective said first ends of said support element;
- said sock being configured to contain an elastic return of said support element, in case said support element arranged, in use, in said at least one said operating position is sheared off;
- said sock having a first length greater than a second breaking length of said support element in a presence of a load parallel to a first extension axis of said support element in said at least one operating position, so that when said support element in use breaks, said sock remains intact at said second breaking length;
- said second breaking length being a maximum breaking length reached, in use, by said support element under the action of said load;
- wherein said sock has a breaking section at one of its ends arranged on a side of said fuselage and opposite to said load.
