Problems solved by technology

Foreign manpower adopts the glider layout, that is, by increasing the aspect ratio to reduce the induced resistance and increase the lift-to-drag ratio, this brings about a problem. The design of the wing is narrow and long, and the reduction of the chord length makes the structure The height is very limited, so ultra-light materials with very high specific strength must be used, and the requirements for the manufacturing process are very high, so it is more expensive to manufacture a human-powered aircraft without any power and on-board equipment than a normal light aircraft much more difficult
[0004] On the other hand, the wingspan of a human-powered aircraft according to this layout is usually about 30 meters, so it can only be used for verification experiments, and it cannot be used as a commodity to provide flight experience for aviation enthusiasts, and it does not have market promotion value

Embodiment

[0029] The human-powered aircraft with tailless ground effect wing layout of this embodiment is mainly composed of wings, end plates, fuselage, rudder, landing gear, propeller and other components. A pilot sits in the fuselage in a riding posture, The way to drive the propeller to rotate to generate pulling force to drive the aircraft forward. The wing adopts S airfoil to ensure longitudinal stability. The installation angle α between the chord line and the horizontal reference plane of the fuselage is taken as 6-7 degrees, and the aspect ratio of the wing is taken as 2. Will exceed 20. An adult can continuously produce 360w power of about 5kg pulling force. The designed aircraft has a span length of 8m and a chord length of 4m. It flies at a speed of 5m / s at a height of 2m and generates a lift of 100kg. Assuming that the human body weighs 65kg, the aircraft is empty The weight must be controlled within 35kg. Except for chain gear bearings, the transmission system and propel...

Abstract

The invention relates to a man-powered aircraft with a non-tail wing-in-ground layout, which comprises a fuselage, wings, a pair of end plates, a propeller, a rudder, a landing gear and a man-powered take-off running system. The wings are fixed on the upper part of the fuselage, the end plates are respectively suspended on the outer ends of the two sides of the wings, the propeller, the rudder and the landing gear are respectively arranged on the front end, the rear end and the lower part of the fuselage, and the man-powered take-off running system is respectively in transmission connection with the propeller, the rudder and the landing gear. Compared with the prior art, the invention has the advantages of high lift-drag ratio, small and light structure and simple and practical use.

Description

technical field [0001] The invention relates to a human-powered aircraft and an ultra-low-altitude powered aircraft, in particular to a human-powered aircraft with tailless ground-effect wing layout. Background technique [0002] Successfully flying human-powered aircraft usually use a pedal crankshaft to drive the propeller. In order to match the power that an adult can provide, the empty weight of the aircraft is usually about 30kg, the wingspan is about 30m, and the aspect ratio is more than 20 times. In order to control the weight, The aircraft is manufactured using high-grade carbon fiber materials. A human-powered aircraft can fly continuously below 3m at a speed of less than 10m / s. [0003] At present, there are no successful reports of human-powered aircraft in our country. The reason is that the power that humans can provide is too small, only about 360W. Therefore, the aircraft must be light enough and must have a large enough lift-to-drag ratio and lift surface....
