Description

A human-powered variable-wing aircraft

technical field

A human-powered variable-wing aircraft belongs to the technical field of aviation, and in particular relates to a variable-wing aircraft.

Background technique

Traditional human-powered aircraft fly entirely by human power, and the flying distance is not far enough. And it takes more effort to take off and requires a longer runway.

Contents of the invention

The purpose of the present invention is to overcome the above-mentioned deficiency of traditional manpower plane, invent a kind of manpower variable-wing plane that does not need long runway to take off, can fly longer distance.

A human-powered variable-wing aircraft comprises a fuselage, a folding propeller, a movable left wing, a movable right wing, an empennage, a landing gear, an air storage tank, a control system and a manpower transmission system. The driver is located in the front section of the fuselage, and the gas storage tank is placed in the middle section of the fuselage. Before take-off, the air storage tank is filled with high-pressure gas, and the gas used is air or nitrogen. The movable left wing and the movable right wing have the same left-right symmetrical arrangement on the left and right sides of the symmetrical longitudinal section of the fuselage, and are placed on the top of the fuselage. Empennage includes vertical empennage and horizontal empennage. The vertical stabilizer is composed of a fixed vertical stabilizer at the front and a movable rudder at the rear; the horizontal stabilizer is composed of a fixed horizontal stabilizer at the front and an elevator movable at the rear. The elevator is deflected up and down under the control of the control system, and the upward deflection will cause the aircraft to raise its head to achieve pitch-up; the downward deflection of the elevator will cause the aircraft to bow its head to achieve pitch-down. The rudder deflects left and right under the control of the control system, making the aircraft yaw left or right. The landing gear adopts three-point wheeled landing gear. The driver manipulates the control system to control the opening and closing of the movable left wing and the movable right wing, as well as control the turning and pitching flight attitude of the aircraft. The launch pad used for the air launch of the aircraft is fixedly installed on the ground. The included angle between the table top of the launch pad and the horizontal plane is between 14° and 46°, and the table top is equipped with three positioning piles for supporting the wheels of the aircraft landing gear.

The flight mode of the manpower variable-wing aircraft of the present invention is: adopt jet gas mode to take off, earlier this aircraft that movable left wing and movable right wing are gathered is carried on the launch pad, and three wheels of landing gear are respectively placed in three positions on the launch pad table top. pile above. The driver turns on the injection switch of the gas storage tank through the control system, and the gas in the gas storage tank is sprayed backward and downward at a high speed. Under its reaction, the aircraft flies forward and upward at high speed. After the air pressure in the gas storage tank is equal to the external pressure Due to inertia, the aircraft continues to fly forward and upward with an approximately parabolic trajectory. After the aircraft reaches the apex of the parabola, the driver manipulates the movable left wing and the movable right wing to gradually open simultaneously, and then uses the pedal manpower transmission system to rotate the folding propeller to start the manpower flight mode. The driver realizes the turning and pitching flight attitude of the aircraft by manipulating the empennage. Finally landed on a relatively flat land.

The outstanding advantage of this invention is a kind of manpower variable-wing aircraft: energy saving, high efficiency and environmental protection. Since the movable left wing and the movable right wing are in a closed state during the process of taking off to the highest point, the resistance is small, the energy loss is small, the efficiency is high, and it can fly farther.

The manpower variable-wing aircraft of the invention is suitable for sports entertainment and aerial photography.

Now in conjunction with accompanying drawing 1～3, the present invention is described in detail: a kind of manpower variable-wing aircraft, comprises fuselage 1, foldable propeller 2, movable left wing 3, movable right wing 4, empennage 5, landing gear 6, gas storage tank 7, Control system and human transmission system. The driver is located in the front section of the fuselage 1, and the gas storage tank 7 is placed in the middle section of the fuselage 1. Air storage tank 7 is full of high-pressure nitrogen before taking off. The movable left wing 3 and the movable right wing 4 have the same structure and are symmetrically arranged on the left and right sides of the symmetrical longitudinal section of the fuselage 1, and placed on the top of the fuselage 1. Empennage 5 comprises vertical empennage and horizontal empennage. The vertical tail is made up of a fixed vertical stabilizer 51 at the front and a movable rudder 52 at the rear; the horizontal tail is made up of a fixed horizontal stabilizer 53 at the front and an elevator 54 that is movable at the rear. The elevator 54 is deflected up and down under the control of the control system, and the upward deflection will cause the aircraft to raise its head to achieve pitching up; the downward deflection of the elevator 54 will cause the aircraft to bow its head to achieve pitching down. Rudder 52 deflects left and right under the control of the control system, making the aircraft yaw left or right. Landing gear 6 adopts three-point wheel type landing gear. The driver manipulates the control system to control the opening and closing of the movable left wing 3 and the movable right wing 4, and controls the turning and pitching attitude of the aircraft. The launching platform 8 that is used for this aircraft starting air is fixedly installed on the ground 9. The angle between the table top and the horizontal plane of launch pad 8 is 45 °, and the table top is equipped with three positioning piles 81 in order to support the wheels of this aircraft landing gear.

The driver opens the injection switch 71 of the gas storage tank 7 through the control system, and the gas in the gas storage tank 7 sprays out at a high speed backward and downward, and under its reaction, the aircraft flies forward and upward at a high speed. After the external air pressure is equal, the aircraft continues to fly forward and upward with an approximate parabolic trajectory due to inertia. After the aircraft reaches the apex of the parabola, the driver manipulates the movable left wing 3 and the movable right wing 4 to gradually open simultaneously, and then uses the pedal manpower transmission system to make the folding propeller 2 rotate to start the manpower flight mode. The driver realizes this aircraft turning and pitching flight attitude by manipulating empennage 5. Finally landed on a relatively flat land.
