Description

Novel three-dimensional omnidirectional control structure

Technical Field

The utility model relates to a coaxial two rotor aircraft accessory technical field specifically is a novel three-dimensional omnidirectional control structure.

Background

The coaxial double-rotor aircraft has a more obvious volume advantage compared with a single-rotor helicopter. Since the rotor of a single-rotor helicopter rotates in the opposite direction, a moment in the horizontal direction is generated, and in order to counteract the moment, a tail rotor is required to balance the moment in the horizontal direction of the helicopter. The previous experience of the scovy in combat afghanistan has shown that 30% of the scovy helicopters lost in combat are associated with the tail rotor. The coaxial double-rotor aircraft does not have a long tail rotor behind a single-rotor helicopter, so that the structure of the coaxial helicopter is more compact. Compared with the Su-Union twin-rotor helicopter, namely the card-50, the speed is higher, the fuselage is smaller, the operation is more flexible, the endurance is longer, and no tail slurry is needed. However, the coaxial helicopter has a complex mechanical structure and high maintenance requirements, and has higher requirements on a flight control system. In this context, we want to design a coaxial twin-rotor aircraft with a simpler mechanical structure than a coaxial helicopter and with a relatively easy flight control system. However, the tilt disk control structure of the coaxial twin-rotor helicopter or single-rotor helicopter which is mature in the market at present has no way to realize stable and reliable application directly on the coaxial twin-rotor helicopter. Therefore, it is necessary to design a new three-dimensional omnidirectional control structure.

SUMMERY OF THE UTILITY MODEL

To the above situation, for overcoming prior art's defect, the utility model provides a novel three-dimensional omnidirectional control structure, the utility model discloses novel structure thinks about ingeniously, and the rotatory outer ring of swash plate links together through bulb pull rod or connecting piece with the above-mentioned screw installing frame limit apart from part, realizes that the equiangular velocity is rotatory, can not only guarantee that the screw can be very in the same direction as smooth realization cycle displacement, adopts the structure of four paws moreover, can use on single swash plate or the coaxial two rotor crafts of two swash plates etc. to can realize stronger commonality and modular design.
