Problems solved by technology

[0005] At present, the single-wing tilting aircraft is still mainly traction type, and it is mainly an upper wing. Although there is a large adjustment margin in avoiding the threat range of the high-energy rotor, its high main wing makes the propeller on it vertically The take-off state hangs high above the whole machine, and the utilization rate of the ground effect is not ideal, which indirectly leads to greater energy consumption in the take-off state

Embodiment Construction

[0026] The present invention will be described in further detail below through the embodiments in conjunction with the accompanying drawings.

[0027] A traction propulsion combined power-tilt wing vertical take-off and landing manned aircraft, such as Figure 1-3 Shown, comprise fuselage 1, landing gear 2, tiltable front wing 3, tiltable rear wing 4, empennage 5, rotor system 6, rotor ring 7; Both sides of the front end of the body 1 are driven by a tilting motor, and the tiltable rear wing 4 is arranged on both sides of the rear of the fuselage 1 and driven by a tilting motor; Two traction-type front propellers carried by the tiltable front wing 3, and two push-type rear propellers arranged on the tiltable rear wing 4 and respectively located on both sides of the fuselage 1; the empennage 5 is arranged on the fuselage 1 The tail has the function of a conventional empennage; the fuselage has room for at least two passengers and control systems.

Abstract

The invention discloses a traction-propulsion type tilt wing vertical take-off and landing manned aircraft, which is characterized in that tiltable front wings are arranged on the two sides of the front end of a fuselage, and tiltable rear wings are carried on the two sides of the rear portion of the fuselage; a rotor wing system comprises a traction-type front propeller which is arranged at the front end of the fuselage and is carried by a tilting front wing, and propulsion-type rear propellers which are arranged on a tilting rear wing and are respectively positioned on two sides of the fuselage; an empennage is arranged at the tail of the fuselage; and the fuselage has a space for accommodating at least two passengers and an operating system. According to the empennage of the aircraft, the stability and the maneuverability of the aircraft in the tilting transition stage and the cruising process are improved; the multi-point symmetrical power layout formed by the multiple propellers enables the aircraft to have enough pitching and rolling balance redundancy in the vertical take-off and landing state and the hovering state, and the safety redundancy of the whole aircraft is improved; a relatively independent tilting mechanism enables the aircraft to have stronger maneuvering characteristics in vertical take-off and landing and hovering states; and the rotor ring way improves the propeller efficiency and the safety of the high-energy rotor.

Description

technical field [0001] The invention belongs to the field of tilting-wing aircraft, and in particular relates to a traction-propulsion type tilting-wing vertical take-off and landing manned aircraft. Background technique [0002] With the rapid development of battery energy density and power density and the application of related products, as well as the further increase of motor output power, the conditions of the era for the development and application of distributed electric power manned aircraft have become increasingly mature. As far as the field of distributed electric vertical take-off and landing manned aircraft is concerned, four types of layouts are currently known: multi-rotor, tilt-rotor, tilt-wing and compound. For multi-rotor aircraft such as patent CN206087301U, which need to adjust the flight attitude by controlling the propeller pitch, its attitude control efficiency is far inferior to that of aerodynamic rudder surfaces or even type vector power units.
