Abstract

The invention discloses an air-breathing lifting body aircraft which comprises an aircraft body, a front aircraft wheel, a rear aircraft wheel, a vertical tail wing, a rudder, wings, ailerons, wherein the top part of the aircraft body is provided with an cambered-surface shell, a negative pressure cavity is arranged below the cambered-surface shell, an air inlet is arranged on the cambered-surface shell and is communicated with the negative pressure cavity, a power machine is arranged on each of the left side and the right side below the middle part of the aircraft body, an output shaft of each power machine is connected with a centrifugal vane wheel above the output shaft, the centrifugal vane wheels are arranged in a volute, one end of the volute is communicated with the negative pressure cavity, the other end of the volute is an air jet hole, and an inner air guide plate and an outer air guide plate are arranged at the two sides of the air jet hole of the volute. According to the air-breathing lifting body aircraft, flowing air generates lifting force above the cambered-surface shell at the top, extra strong lifting force is generated near the air jet hole due to the Coanda effect. The air-breathing lifting body aircraft has much higher efficiency in lifting generation than a common airplane, is safe and reliable, economical, and has strong adaptability and short flight distance in take-off and landing.

Description

technical field [0001] The invention belongs to an air-breathing lifting body aircraft. Background technique [0002] Small and medium-sized manned aircraft have been widely used and developed rapidly in the civilian field in recent years because of their lightness, small size and flexibility, and they only need to park and take off and land at small airports. Light and small aircraft represent an important development direction of future transportation tools. Among various small-scale manned aircraft solutions such as light aircraft, ultra-light aircraft, and flying cars, aircraft with short-distance take-off and landing capabilities have relatively large advantages. However, there are still many unsatisfactory parts and some shortcomings in the use and flight of existing small aircraft, such as high noise, long take-off and landing distance, and short flight range. Contents of the invention [0003] The object of the present invention is to provide an air-breathing lift...
