Description

ring wing vertical takeoff and landing aircraft

technical field

The utility model relates to a propeller aircraft, in particular to a circular-wing vertical take-off and landing aircraft capable of stably and safely vertically taking off and landing, staying and flying without the propeller whirling against surrounding objects.

Background technique

Known propeller vertical take-off and landing aircraft such as helicopters, model airplanes (or toy) propeller aircraft, etc. include organisms, control devices, power units and propellers. The control device and the power unit are installed in the body, and the propeller is installed above the body. There are two types of vertical take-off and landing aircraft with multiple propellers and a small rotor with single propeller and tail rudder. All rely on the rotation of the propeller, so that the air on the upper and lower surfaces of the propeller produces a pressure difference to bring lift to the aircraft, and then adjust the flight attitude of the aircraft by controlling the pitch of each blade of the aircraft or controlling the small rotor of the tail rudder of the aircraft. direction. Because the aircraft will have enough lift to lift off, the diameter of its propeller is relatively large. The propeller is easy to spin against the surrounding objects when the aircraft is flying and staying, which makes the operation of the aircraft and the requirements for the terrain very harsh, and constitutes a potential and continuous threat to the safety of the aircraft. This is its shortcoming.

Contents of the invention

Aiming at the shortcomings of the propellers of the existing propeller aircraft, the purpose of this utility model is to provide such a ring-wing vertical take-off and landing aircraft, the propeller of the aircraft will not spin against the surrounding objects, so that the operation of the aircraft and the requirements for the terrain are changed. The invention is simple, and at the same time, the annular wing also has the effect of increasing the lift force of the aircraft, and has the effects of safety and energy saving.

The technical scheme adopted by the utility model to solve its technical problems is: including the body, the control device, the power device and the propeller, the control device and the power device are installed in the body, and the propeller is installed on the top of the body. It is characterized in that: it also includes a ring Wing, the shape of the annular wing narrow at the top and wide at the bottom is in the shape of a ball table (spherical ring) or a truncated cone, and surrounds the propeller, and is at the same level as the propeller.

The beneficial effects of the utility model are: the annular wing can not only protect the propeller from spinning against objects close to the aircraft during take-off, landing, flight and stay, but also prevent the horizontal wind from directly blowing on the propeller to affect the normal operation of the aircraft . And it can generate a certain lifting force, which plays the role of safety and energy saving. Simplify the operation of the aircraft and the requirements for the terrain. In particular, a rectifying device is added in its embodiment, which can convert most of the lateral torsion force generated by the rotation of the propeller into a downward thrust, so that the aircraft will not produce left and right torsion during take-off and landing, flight and air stay, and can stably Vertical take-off and landing, flying and making air stops.

Detailed ways

Referring to the accompanying drawings, the utility model comprises a body 1, a control device, a power device and a propeller 2, the control device and the power device are installed in the body 1, and the propeller 2 is installed above the body 1, and is characterized in that: it also includes an annular wing 4, This ring-shaped wing 4 is the spherical zone ring shape (that is, the shape of a ball table) or the shape of a truncated cone that is narrow above and wide below, and surrounds the outside of the propeller, and is on the same horizontal band as the propeller.

In the embodiment of the present utility model, the rectifying device in "Propeller VTOL aircraft with rectifying device" which the applicant applied for patent protection on the same day is installed, so that the utility model also includes a rectifying device 3, which rectifying device 3 includes at least two rectifying plates 31, 32, the plates of the rectifying plates 31, 32 are perpendicular to the rotating surface of the aircraft propeller 2, and the rectifying plates 31, 32 are placed crosswise. Connected in the shape of "well", "feng", and "m", the rectifying plates 31, 32 are connected into a whole through connecting members 33, 34; the machine body 1 is installed on the rectifying plates 31, 32.

The bottoms of the rectifying plates 31, 32 are linear, so that the bottoms of the rectifying plates 31, 32 can be in a plane after crossing, so that the whole aircraft can be parked on the ground smoothly. The rectifying plates 31 and 32 can change the lateral torsion force formed by the rotation of the propeller 2 into a downward thrust, so that the aircraft will not produce torsion.
