The method of installing the driving mechanism under the plate wing to enhance lift and realize vertical take-off and landing

Abstract

The invention discloses a method for installing a drive mechanism under a plate wing to enhance lift and realize vertical take-off and landing, which belongs to the field of aviation technology. For the aircraft with a large-area plate-shaped wing, a driving device is provided at the front lower part of the leading edge of the plate wing, and the driving device blows high-speed airflow to the lower part of the plate wing along the chord direction. Exhaust from the bottom, so a negative pressure area is formed above the wing, and a positive pressure area is formed under the wing, and the vertical take-off and landing can be realized by using the pressure difference lift formed by the negative pressure area and the positive pressure area; at the same time, the wing can be designed as The combined type further improves the vertical take-off and landing capability and flight efficiency. When flying horizontally, the wings are folded into a fixed-wing shape with little resistance. The forced reflection is vertically downward, and the effect of increasing lift and reducing drag is obviously enhanced, which well takes into account the different requirements of horizontal flight and vertical take-off and landing.

Description

technical field [0001] The invention relates to a method for realizing vertical take-off and landing of an aircraft, in particular to a method for installing a driving mechanism under a plate wing to enhance lift and realize vertical take-off and landing, which belongs to the field of aviation technology. Background technique [0002] Manned aircraft can be divided into two categories: fixed wing and rotary wing. Fixed wing is commonly used in horizontal take-off and landing aircraft (such as jet airliners), while rotary wing is commonly used in vertical take-off and landing aircraft (such as helicopters). As far as the current technical level is concerned, fixed-wing aircraft can fly at high speed and are easy to operate, but they need to rely on runways to take off and land. Rotary wing aircraft can take off and land vertically without relying on runways, and has strong adaptability, but the mechanism is out of balance, the control is complicated, the flight speed is slow,...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the flight efficiency of the existing vertical take-off and landing aircraft is low, the thrust-to-weight ratio is generally less than 1, the control is complicated, the safety is poor, the conversion between the horizontal flight mode and the vertical take-off and landing mode is not smooth and natural, and the existing board-wing aircraft Due to problems such as excessive wing resistance, insufficient vertical lift and divergence of chord-wise blowing airflow, a method of installing a drive mechanism under the wing to enhance lift and achieve vertical take-off and landing is proposed. After increasing the lift to achieve vertical take-off and landing, it can be Reduce resistance to achieve high-speed flight, making the board wing aircraft safer, more efficient, more compact, more stable and more reasonable
