Main wing retractable type fixed wing airplane

Abstract

The invention provides a main wing retractable type fixed wing airplane which is a transportation vehicle capable of flying in the air. In order to solve the problems that an existing airplane cannot fly and descend in an economical and energy-saving manner, the design is carried out. The main wing retractable type fixed wing airplane is structurally characterized in that a specially-designed outrigger box and a fuselage cross beam are connected in a fastened manner and straightly stretch out of the two sides of a wing; a cantilever is used for bearing acting forces of sliding wing sections in all directions; the sliding wings on the two sides freely retract and slide in an outer sleeve wing on the surface of the outrigger box due to control and limitation of action cylinders; the wing expansion and the wing shape can be changed by flying speeds; a semi-driving type vertical fin is also designed to retract up and down to adjust the control area, so that the flying resistance of the whole airplane is reduced, and the adapting thrust is reduced; the main wing retractable type fixed wing airplane is economical, environment-friendly and safe, and the navigability also can be improved; in order to be adapted to the gravity center change caused by the speed change of the airplane, a gravity center adjusting vehicle mounted on a guide rail is designed, and a trimming power vehicle is controlled to move forwards and backwards to adjust the gravity center; and the part construction is shown as a figure of the specification in detail, and an airplane designing and manufacturing enterprise can produce the applicable product according to the design.

Description

Technical field: [0001] A means of transportation in the air. [0002] In 2014, 2013, 2012, and 2011, no similar products were found in the "China Intellectual Property Office Patent Application Publication (Announcement) Index", and no similar products were found in the materials and magazines published at home and abroad. There is no product with the same effect in the air vehicle. Background technique: [0003] (Main wing retractable fixed-wing aircraft) is designed to solve the contradictory problem of high-speed flight and low-speed take-off and landing that existing fixed-wing aircraft at home and abroad cannot realize economical and energy-saving. [0004] In order to reduce the flight resistance when flying at high speed, the existing aircraft wings at home and abroad can only adopt a compromise solution when the aircraft wings have enough lift when flying at low speeds. The wing area is designed so that it will not generate Too much excess lift can take off and la...

Problems solved by technology

[0003] (Main wing retractable fixed-wing aircraft) is designed to solve the contradictory problem that existing fixed-wing aircraft at home and abroad cannot achieve economical and energy-saving high-speed flight and low-speed take-off and landing.

[0004] In order to reduce the flight resistance when flying at high speed, the existing aircraft wings at home and abroad can only adopt a compromise solution when the aircraft wings have enough lift when flying at low speeds. The wing area is designed so that it will not generate Too much excess lift can take off and land safely at low-speed take-off and landing, while at high-speed flight the excess lift will generate excess resistance, which will increase the extra economic cost of flight, and at low-speed take-off and landing the wing The lift is insufficient, so it has high requirements for the airport conditions, so its airworthiness is greatly restricted
