A vibration filter mechanism between a fuselage and a piece of equipment of the aircraft. The filter mechanism comprises a pair of filter members, each secured with a first structure that is to be connected to the fuselage and with a second structure of the piece of equipment. Each filter member is secured with the first structure via a first pivot type connection having one degree of freedom to move in rotation and with the second structure via a second pivot type connection having one degree of freedom to move in rotation. The filter mechanism includes resilient return means for deforming during relative movement in rotation between at least one of the filter members and the first structure. The resilient return means presents a predetermined stiffness suitable for generating a return force opposing the relative movement in rotation between at least one of the filter members and the first structure.

Vibration filter mechanism for arranging between a piece of equipment and an aircraft fuselage, and a seat fitted with such a mechanism

The invention relates to a compound helicopter comprising a fuselage, at least one engine and a main rotor driven by said at least one engine. At least one pair of fixed wings are mounted in an essentially horizontal plane on a left hand and a right hand side of the fuselage and horizontally oriented propulsion devices are mounted to each of the fixed wings, the fixed wings encompassing each a drive shaft from the at least one engine. Each fixed wing comprises a lower main wing and an upper secondary wing being connected to each other within an interconnection region. The propulsion devices include pusher propellers arranged at the interconnection region and the upper secondary wing houses the drive shaft from the at least one engine.

Compound helicopter

The present invention is related to a compound helicopter with a main rotor providing lift, a pair of additional propulsion devices providing thrust and anti-torque and a fixed wing structure on each side providing additional lift during horizontal cruise flight. The propulsion devices are arranged at each side of a fuselage body with two tail booms, one arranged at each side of the fuselage body, each of both tail booms having one of both propulsion devices arranged at its boom rear end. Each of the two tail booms houses an engine and a drive shaft driving the corresponding propulsion device.
