Method for achieving vertical taking-off and landing and horizontal flying by means of subsection bottom drive type plate fins

Abstract

The invention discloses a method for achieving vertical taking-off and landing and horizontal flying by means of subsection bottom drive type plate fins, and belongs to the technical field of aerospace. A large-area plate-shaped wing is transversely cut into a plurality of sections of movable strip-shaped plate fins and fixed strip-shaped plate fins, the fixed strip-strip-shaped plate fins and anaircraft body are in rigid connection, no motion component is adopted, the movable strip-shaped plate fins are connected with the aircraft body through transverse hinges, and longitudinal tilting canbe achieved; the lower portions of the movable strip-shaped plate fins are fixedly connected with drive devices and tilt and rotate like window shades, the large-area plate-shaped wing is combined when converted into the horizontal state, the drive devices are connected in series in a front-back mode, high-speed airflow is blown from the lower portion of the wing in the chord direction to achievehorizontal flying, strip-shaped air inlets are opened when converted into the vertical state, the drive devices are connected in parallel in a front-back mode, air is sucked from the upper portion ofthe wing, an air is exhausted to the lower portion of the wing, so that perpendicular taking-off and landing are achieved; the different requirements for horizontal flying and vertical taking-off andlanding are met, the vertical taking-off and landing capability and flying efficiency are improved, stable conversion between flight modes is achieved, and the method is stable in working, visual in operation, safe, reliable and simple and easy to implement.

Description

technical field [0001] The invention relates to a method for realizing vertical take-off and landing and flight of an aircraft, especially a method for installing a driving mechanism under a plate wing and dividing the plate wing into multiple sections so as to open the air intake channel to enhance the lift force of the vertical take-off and landing and take into account the horizontal flight method , belonging 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 ...

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 small, 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 wings of the existing plank wing To deal with problems such as excessive resistance, insufficient vertical lift, and divergence of the chord-wise blowing airflow, a method of using a segmented bottom-driven plate wing to achieve vertical take-off and landing and horizontal flight is proposed. The plate wing is divided into multiple sections to open the air intake channel and enhance the vertical The lift of take-off and landing takes into account the horizontal flight. After the movable strip-shaped wing rotates to open the intake channel to increase the lift to realize vertical take-off and landing, the movable strip-shaped wing can be rotated and closed, and it can be closed with the fixed strip-shaped wing to form a whole. plate wing, so as to reduce resistance and achieve high-speed flight, making the plate wing aircraft safer, more efficient, compact, stable and reasonable
