Problems solved by technology

At present, the aircraft used in cities is mainly helicopters. Although it solves the problem of vertical take-off and landing, it has complex structure, difficult maintenance, poor reliability and high cost, and the large rotor reduces the efficiency and cruising speed of the forward flight stage.

[0027] figure 1 -3 represents a single-person aircraft with vertical take-off and landing (VTOL) capability according to the first embodiment of the present invention, which includes a fuselage 1, wings 2, side wings 3, engines 4, variable-pitch rotors 5, linkage Shaft 6, elevon 7, landing gear 8, parachute 9, parachute compartment 10 and canopy 11. The one-man flying vehicle according to this embodiment works as follows:

[0028] - In the vertical take-off and landing phase, the head of the aircraft is facing upwards, and it takes off and lands in a tail position. The engine 4 drives two variable-pitch rotors 5 to rotate to generate lift to overcome gravity and realize vertical take-off and landing. At this stage, the heading stability is maintained by adjusting the pitch difference of the variable-pitch rotor 5, and the stability and control of roll and pitch are realized through the deflection of the elevon 7, since the elevon 7 is in the slipstream region of the variable-...

[0036] Figure 4 A single-person aircraft with vertical take-off and landing (VTOL) capability representing the second embodiment of the present invention, which includes a fuselage 1, wings 2, side strip wings 3, electric motors 12, fixed-distance rotors 13, small vortex Fan engine 14, elevon 7, landing gear 8, parachute 9, parachute compartment 10, canopy 11 and battery 15 ( Figure 5 ). The one-man flying vehicle according to this embodiment works as follows:

[0037] - In the vertical take-off and landing phase, the tail-sitting method is also used to take off and land, and the battery 15 ( Figure 5 ) to supply power to the motor 12, and the motor 12 drives the two fixed-distance rotors 13 to rotate to generate lift to overcome gravity and realize vertical take-off and landing. At this stage, the heading stability is maintained by adjusting the rotational speed difference of the fixed-pitch rotor 13, and the stabilization in other directions is the same as in the first...

Abstract

The invention provides a single aircraft with vertical take-off and landing capacity. The single aircraft comprises a body (1), wings (2), rotor wings (5 and 13) which are arranged on the wings (2) on two sides, and elevons (7) which are arranged at the rear edges of the two wings (2), wherein rolling and pitching can be stabilized and controlled through deflection of the elevons (7); in a vertical take-off and landing period, the head of the aircraft is upward; the aircraft takes off and / or lands in a tail seat manner; the gravity is overcome through elevating force generated by rotation of the rotor wing (5); vertical take-off and landing can be realized. The single aircraft has the advantages that (1) through a tailless layout, the air resistance is effectively reduced, and the flight speed is increased; (2) the advantages of a helicopter and a fixed wing aircraft are taken into consideration, and high efficiency can be maintained in both high-speed level flight and low-speed hovering periods; (3) a rotary mechanism is eliminated, and the single aircraft is simple in structure, high in reliability and low in cost; (4) the aircraft can be stabilized and controlled under low-speed and large-incidence conditions, and is applied to city airspace; (5) an emergency is handled in an engine connecting shaft and full-aircraft parachute-opening manner, and the aircraft is high in safety.

Description

technical field [0001] The invention relates to a single-person aircraft capable of vertical take-off and landing, and belongs to the technical field of fixed-wing aircraft design in aviation aircraft. Background technique [0002] As the urban ground traffic becomes more and more crowded and busy, people pay more and more attention to how to use the urban airspace to alleviate this phenomenon. Due to the high-rise buildings in the city and the long distance from the airport to the destination, there are great limitations to conventional fixed-wing aircraft that can only take off and land by taxiing. [0003] Aircraft with vertical take-off and landing capabilities can use the open space in the city to complete take-off and landing, and can easily shuttle between buildings, so they are more adaptable to urban airspace. At present, the aircraft used in cities is mainly helicopters. Although it solves the problem of vertical take-off and landing, it has complex structure, dif...
