Description

Technical Field

[0001] The present invention relates to the technical field of rotorcraft structure and flight control, and in particular to a jellyfish aircraft. Background Art

[0002] With the introduction of low-altitude economy policies, drone applications are expanding. Some regions have even begun experimenting with drones for food delivery, daily necessities, and agricultural supplies. Common drones can be categorized as rotary-wing, fixed-wing, and flapping-wing. Rotary-wing drones offer advantages such as vertical takeoff and landing, hovering capabilities, high maneuverability, excellent flexibility, ease of operation, and low cost. These advantages have made them a dominant force in the low-altitude economy.

[0003] Most traditional single-rotor drones use a tail rotor to offset the anti-torque, and their directional control is mainly controlled by the cyclic pitch and speed of the main rotor and the thrust of the tail rotor. Multi-rotor drones mainly rely on differential adjustment of the speed of symmetrical rotors to control the flight direction. These two types of rotors mainly fly in a vertical posture and are inconvenient to carry due to their specific structure. Summary of the Invention

[0004] The purpose of the present invention is to provide a jellyfish aircraft, which can be folded when it is not needed and unfolded when it is needed. It can fly in a vertical posture and a horizontal flight posture, and has the technical effects of simple structure, convenient control, and maneuverability.

[0006] Furthermore, the motor is arranged below the rotor and fixed to the top of the sleeve. When the aircraft needs to be used, the vertical plates I and II are crossed, and the shaft ring III and the shaft ring I, and the shaft ring IV and the shaft ring II are fixed by pins. When the aircraft is not needed, the pins can be removed and the two vertical plates can be combined into one plate.

[0007] Furthermore, the jellyfish aircraft has a control mode. By controlling the three rudders to deflect at a small angle through a program, the aircraft can be controlled to move forward and turn in a vertical posture. The rudders I and II can also be controlled to deflect forward at a large angle at the same time to rotate the aircraft to fly in a level flight posture. When the aircraft is flying in a level flight posture, the aircraft can be controlled to raise its head, lower its head and turn by controlling the three rudders to deflect at a small angle.

[0008] In summary, the beneficial effects of the present invention are: The jellyfish aircraft of the present invention uses a double-bladed rotor that can be easily folded when the aircraft is not in use. The coaxial twin rotors offset torque. The rotors are fixed to the top of a sleeve II. When the aircraft is in use, two vertical plates are cross-crossed, and axle rings III and I, and axle ring IV and II are fixed with pins. When the aircraft is not in use for takeoff, it is folded and folded for easy carrying. When it is needed for takeoff, it can be unfolded crosswise. No drop or runway is required for takeoff, and the aircraft can take off vertically, fly in a vertical attitude, or in a level flight attitude, and can be monitored at a fixed point. The jellyfish aircraft of the present invention can be controlled by program-controlled small-angle deflection of three control surfaces to control the aircraft to advance and turn in a vertical attitude.

The vertical plate I21 is fixedly connected to the shaft ring II 23. The shaft ring III 31 is located at the upper end of the shaft ring I22. The shaft ring III 31 and the shaft ring I22 are fixed by pin 3. When the pin 3 is pulled out, the shaft ring III 31 can rotate around the sleeve I1. The shaft ring IV 32 is located at the upper end of the shaft ring II 23. The shaft ring II 23 and the shaft ring IV 32 are fixed by pin 3. When the pin 3 is pulled out, the shaft ring IV 32 can rotate around the sleeve II 2. The middle part of the vertical plate I21 is equipped with a steering gear III 24. The steering gear III 24 is connected to the shaft ring I22. Connected to tie rod III 25, the other end of tie rod III 25 is connected to control surface III 26. Rotor 41 uses a coaxial two-blade dual rotor to offset torque. Servos I 33 and II 34 are fixed to the middle of vertical plate II 39. Servo I 33 is connected to tie rod I 35, and servo II 34 is connected to tie rod II 36. The other end of tie rod I 35 is connected to control surface I 37, and the other end of tie rod II 36 is connected to control surface II 38. Motor 42 is located below rotor 41 and fixed to the top of sleeve II 2. Rotor 41 uses a coaxial two-blade dual rotor to offset torque. Rotor 41 is fixed to the top of sleeve II 2. When the aircraft is in use, the two vertical plates are crossed, and pin 3 is used to secure collar III 31 to collar I 22, and collar IV 32 to collar II 23. When the aircraft is not in use, pin 3 can be removed, and the two vertical plates can be combined into a single plate.

[0014] The jellyfish aircraft has a control mode. By controlling the three control surfaces to deflect at small angles through program control, the aircraft can be controlled to move forward and turn in a vertical attitude. The control surfaces I37 and II38 can also be controlled to deflect forward at large angles simultaneously to rotate the aircraft to fly in a level flight attitude. When the aircraft is flying in a level flight attitude, the aircraft can be controlled to raise, lower, and turn by controlling the three control surfaces to deflect at small angles. In one embodiment, the jellyfish aircraft includes a controller.

[0015] The working principle of the jellyfish aircraft includes: Power control: Design a program to make the motor 42 control the rotation of the two rotors 41, thereby providing lift for the aircraft; Direction control: three servos control the deflection of three rudder surfaces to control the direction; Flight attitude control: Controlling the rudder surfaces I37 and II38 to deflect in the same direction at large angles can change the flight attitude of the aircraft.

[0016] The jellyfish aircraft controls the motor 42 through a program to rotate the rotor 41 to generate lift. At this time, the aircraft is in a vertical attitude. When it is to fly forward, the control surfaces I37 and II38 are deflected forward at the same time. The airflow generated by the rotor 41 acts on the control surfaces I37 and II38, and the aircraft generates a forward-leaning moment to make the aircraft fly forward. When the aircraft needs to move forward in the left direction, the control surface III26 can be controlled to deflect to the left. The airflow generated by the rotor 41 acts on the control surface III26, and the aircraft generates a left-leaning moment to make the aircraft fly to the left. When the aircraft needs to rotate, the control surface I37 deflects forward and the control surface II38 deflects backward. The airflow generated by the rotor 41 acts on the control surface I37 to generate a forward-leaning moment. The moment generates a backward tilting moment on the control surface II 38. At this time, the left end of the aircraft is subjected to a forward force and the right end is subjected to a backward force, and the aircraft rotates counterclockwise. When the control surfaces I 37 and II 38 are deflected forward at a large angle at the same time, the flight attitude of the aircraft can be changed from a vertical attitude to a level flight attitude. When flying in a level flight attitude, the vertical plate II 39 can generate some additional lift, and the role of the rotor 41 is equivalent to the thrust generated by the propeller. At this time, controlling the control surfaces I 37 and II 38 to deflect upward at the same time can control the aircraft to raise its head, and deflecting the control surfaces I 37 and II 38 downward at the same time can control the aircraft to lower its head. Deflecting the control surfaces I 37 and II 38 downward and upward at the same time can control the aircraft to roll and yaw. Deflecting the control surface III 26 left and right can control the aircraft to yaw left and right.

[0017] The jellyfish aircraft of the present invention uses a double-bladed rotor that is folded when the aircraft is not in use. A coaxial pair of rotors is used to offset torque. The rotors are fixed to the top of a sleeve II. When the aircraft is in use, two vertical plates are cross-connected, and axle rings III and I, and axle ring IV and II are fixed with pins. When the aircraft is not in use for takeoff, it is folded and folded for easy carrying. When it is needed for takeoff, it can be unfolded crosswise. No drop or runway is required for takeoff, and the aircraft can take off vertically, fly in a vertical attitude, or in a level flight attitude, and can be monitored at a fixed point. The jellyfish aircraft of the present invention can be controlled by program-controlled small-angle deflection of three control surfaces to control the aircraft to advance and turn in a vertical attitude. Control surfaces I and II can also be controlled to deflect in the same direction at large angles to rotate the aircraft to fly in a level flight attitude. When in a level flight attitude, the aircraft can be controlled by controlling the small-angle deflection of the three control surfaces to control the aircraft to rise, fall, and turn.
