A method for enhancing lift and realizing vertical take-off and landing by mounting a drive mechanism under a panel wing

Abstract

The invention discloses a method for enhancing lifting force and realizing vertical take-off and landing by installing a driving mechanism under a plate wing, and belongs to the aeronautical technicalfield. For aircraft with large plate wings, a drive device is provided at the front lower portion of the leading edge of the panel wing, as that drive device sucks air from above the plate we and exhausts the air under the plate wing, a negative pressure region is formed above the plate wing, a positive pressure region is formed below the plate wing, and vertical take-off and landing are realizedby utilizing the pressure difference lifting force formed by the negative pressure region and the positive pressure region; at that same time, the panel we can be designed as a combination to furtherimprove the vertical take-off and landing capability and flight efficiency, in horizontal flight, the wing is folded into a fixed wing with little drag during in vertical take-off and landing, the left and right sides and the rear part of the combined wing reflect the flow direction from horizontal direction to vertical downward, which enhances the effect of increasing lift and reducing drag, andgives good consideration to 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
