Problems solved by technology

[0006] In the history of aviation, there has also been a semi-ring wing (Half ring wing) aircraft, which has a semi-ring appearance, which is equivalent to half of the ring wing, and is placed on both sides of the aircraft. Good lift, short take-off and landing advantages are very obvious, but due to various reasons, this semi-ring wing aircraft has not been widely used
[0007] In recent years, with the rise of the U.S. V22 Osprey tilt-rotor aircraft, countries are strengthening the research on tilt-rotor aircraft. V22 not only has the ability of ordinary helicopters to take off and land and hover in the air, but also has the ability of high-speed cruise flight of fixed-wing aircraft. Capability, the advantage is quite obvious, but the disadvantages of the V22 are also quite obvious, the structure is complex, the maintenance cost is high, the wing load is high, and the surplus power is insufficient during vertical take-off and landing, resulting in frequent failures

Embodiment 1

[0042] Example 1: Takeoff

[0043] 1. Slide mode

[0044] Utilize the landing gear to take off on the runway, when the angle of the rotating device 2 is at 0°, the steering gear 10 controls the flaps 9 to turn down to increase the lift, and the thruster 4 produces a backward thrust. When the semi-ring wing 3 When there are 2 rows of four sets, the power of the front row propellers (4-1, 4-2) is controlled to be greater than the power of the rear row propellers (4-3, 4-4), and the corresponding front row semi-ring wings (3 -1, 3-2) The lift force generated is greater than the lift force of the rear semi-ring wings (3-3, 3-4), thus generating a nose-up moment, the aircraft lifts off the ground, and as the flight speed of the aircraft gradually increases, adjust the front The power of the propellers in the row (4-1, 4-2) is less than that of the propellers in the rear row (4-3, 4-4), and the lift generated by the corresponding front row semi-ring wings (3-1, 3-2) Less than the ...

Embodiment 2

[0050] Example 2: Attitude in the air

[0051] 1. Hover

[0052] The angle of the rotating device 2 is adjusted by the controller. At this time, the rotating device 2 is in the 90° position, and the thrust produced by the propeller 4 is vertically downward. When the control thrust is the same as the weight of the aircraft, the aircraft is in a hovering state.

[0053] 2. Somersault in the air

[0054] In the hover attitude, by increasing the thrust of the left propeller (4-1, 4-3) of the aircraft, while reducing the thrust of the right propeller (4-2, 4-4), the power difference on both sides of the aircraft will affect the aircraft. A yaw moment to the right is generated, and vice versa, a yaw moment to the left is generated, and it can also turn back and forth.

[0055] 3. Normal flight

[0056] Same as the roll take-off, the rotation device 2 angle of the aircraft is at the 0° position, and the propeller 4 produces a backward thrust, and the aircraft is in a level flight ...

Embodiment 3

[0062] Example 3: Landing

[0063] 1. Vertical landing

[0064] By adjusting the angle of the rotating device 2, the rotating device 2 is at a position of 90° at this time, and the thrust produced by the propeller 4 is vertically downward, and by reducing the thrust, the thrust is gradually smaller than the weight of the aircraft, so that the vertical landing of the aircraft is realized.

[0065] 2. Short-distance landing

[0066] Adjust the angle of the rotating device 2 through the controller, usually between 0° and 90°. At this time, the thrust generated by the propeller 4 is obliquely backward, and the thrust can be decomposed into two directions: forward and upward, and then gradually lower the propeller. 4 thrust to realize short-distance landing of the aircraft.

[0067] 3. Rolling and landing

[0068] At this moment, the angle of the rotating device 2 is at the 0° position, and the propeller 4 produces a backward thrust, which gradually reduces the power of the prop...

Abstract

The invention discloses a half ring wing aircraft which comprises propellers, an aircraft body and half ring wings connected with the aircraft body, wherein the propellers control the flight attitudethrough a controller, four sets of half ring wings are arranged and are symmetrically mounted at two sides of the aircraft body, ailerons are respectively arranged at the edges of the half ring wingsat the front row, the propellers are correspondingly mounted above the half ring wings through rotating devices, and the controller controls the angles of the propellers through the rotating devices so as to control the flight attitude. The aircraft provided by the invention is simple in structure; the lifting force generated by the half ring wings is further greater than the lifting force generated by the wings of a helicopter; the aircraft also has the characteristics of large carrying capacity, high flight speed, long voyage, small noise, low energy consumption and the like; and the aircraft provided by the invention cancels the traditional tail wings, is simpler in structure and more flexible in attitude, and improves the operating efficiency.

Description

technical field [0001] The invention relates to an aircraft, in particular to a semi-circular wing aircraft. Background technique [0002] An aircraft is a device that can fly in the atmosphere or outside the atmosphere (space). Aircraft mainly include rotors and fixed-wings, such as helicopters, fixed-wing aircraft, and multi-rotor aircraft. [0003] Because helicopters can take off and land vertically, they have very low requirements for takeoff and landing conditions, especially runways, so they are widely used, such as sightseeing, fire rescue, sea first aid, anti-smuggling and anti-drug, fire fighting, commercial transportation, medical assistance, communication and spraying Pesticides and insecticides are used in various sectors of the national economy such as eliminating pests and detecting resources. However, the disadvantages of helicopters are also obvious, such as small load capacity, low practical ceiling, and especially low speed, which also limits its range of...
