Embodiment 1

[0025] The aircraft has coaxial twin rotors.

[0026] A composite single row rotor tilting aircraft includes a fuselage, wings and an empennage. The aircraft has a frame, and a fixed wing is connected to both sides of the frame. The wingtips of the fixed wing have two electric propellers arranged side by side and connected to a short rod. The short rod connected to the electric propeller is connected to the fixed wing. On the top, the short rod connected to the electric propeller is also connected to the output end where the steering gear is installed on the fixed wing.

[0027] There is an empennage behind the frame, and the empennage is connected with the ducted oars whose rotating shaft is vertically installed with the empennage design as one.

[0028] A rotor frame 11 is arranged in the center between the fixed wings on both sides of the frame, and the rotor frame 11 is connected with a first tilting shaft 3 and a second tilting shaft 4, and the first tilting shaft 3 and ...

Embodiment 2

[0035] The front blade and the rear blade of the coaxial dual rotor can also be connected to the rotor frame 11 by a support member.

[0036] A support tube set on the outer shaft of the rotor shaft 12 is fixedly connected to the rotor frame 11. The front end of the support tube is connected to a branch tube set on the support tube. Fixed on the branch pipe, the front propeller hub is keyed to the inner shaft, and the branch pipe is keyed to the outer shaft.

Embodiment 3

[0038] The aircraft may also have a rotor.

[0039] Rotor is connected on the rotor shaft 12. Alternatively, a set of support tubes sleeved on the rotor shaft 12 is fixedly connected to the rotor frame 11 , the rotor is connected to the support tube, and the rotor hub and the rotor shaft 12 are keyed.

[0040] Rotor shaft 12 is connected on the rotor frame 11 through the axis of the tilting shaft that rotor frame 11 is connected, and rotor shaft 12 can tilt back and forth between horizontal and vertical directions under the drive of tilting mechanism. Rotor shaft 12 connects a 3rd bevel gear 9 or the 4th bevel gear 10 at its rear end, the 3rd bevel gear 9 or the 4th bevel gear 10 and the first bevel gear 7 that the first power rotating shaft 1 is connected and the second power The second bevel gear 8 connected to the rotating shaft 2 is meshed and connected.

Abstract

The invention discloses a combined type single-row rotor wing tilting aircraft, and belongs to the technical field of aircrafts. The aircraft is provided with a rack, fixed wings are arranged on the two sides of the rack, and electric propellers are arranged at wing tips. An empennage is arranged behind the rack and is provided with a ducted paddle. A rotor frame is arranged in the middle between the fixed wings on the two sides of the rack, and the rotor frame is connected with a tilting shaft and a tilting mechanism which are connected to the rack. The rotor frame is provided with a coaxial double rotor or a rotor of which the rotor rotating shaft tilts back and forth between the horizontal direction and the vertical direction. A power rotating shaft for transmitting torque is sleeved in a tilting shaft connected with the rotor frame; and the shaft end of the power rotating shaft in the rotor frame is in shaft connection with the rotor rotating shaft. One or two cabins with relatively independent spaces are constructed on the rack. The aircraft has the characteristics of simple structure and light wings. Only one row of rotor wings tilt, so that the tilting operation is easier, safer and more reliable compared with two or more rows of rotor wings. The aircraft is suitable for scenes of light aircrafts or unmanned aircrafts.

Description

(1) Technical field [0001] The invention relates to an aircraft, in particular to a tiltable rotorcraft. (2) Background technology [0002] A tiltrotor is a unique aircraft. It can not only cruise at high speed like an airplane, but also take off and land vertically like a helicopter, and has a wide range of uses. [0003] Existing tiltrotors have two rows of rotors or multiple rows of rotors, and the components of the rotor tilting system are installed on the wings. Such an arrangement will inevitably complicate the structure of the entire system, and the wings are bulky, which limits its advantages. play and application. [0004] In the conception of the present invention, it is considered whether only one row of rotors can be used to tilt to realize the take-off, landing and cruise of the aircraft, so that the structure of the system can be greatly reduced and the weight of the fuselage can be reduced. Considering that the rotary shaft of the rotor cannot be set very l...
