Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0044] In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specifying the quantity of indicated technical features. Thus, a ...

Abstract

The invention is suitable for the field of manned vehicles, and provides a low-altitude composite aircraft. The low-altitude composite aircraft comprises an unpowered rotor mechanism, a four-rotor mechanism, a tilting-rotor mechanism and a rack used for fixing the mechanisms. The unpowered rotor mechanism is used for providing raising force for the low-altitude composite aircraft, the four-rotor mechanism comprises a left front rotor, a right front rotor, a left rear rotor and a right rear rotor with rotating shafts arranged in parallel and with the same rotating speed, the left front rotor and the right front rotor are arranged left and right and opposite in rotation direction, the left rear rotor and the right rear rotor are opposite in rotating direction, and the tilting-rotor mechanismis used for driving the left front rotor, the right front rotor, the left rear rotor and the right rear rotor at the same time to be subjected to tilting-rotor operation forwards or backwards. The low-altitude composite aircraft achieves vertical ascending and descending and is beneficial to improving of landing safety of the low-altitude composite aircraft, energy consumption is reduced, meanwhile, design is simplified, the producing and manufacturing cost is reduced, and the operation difficulty is reduced.

Description

technical field [0001] The invention belongs to the field of manned aircraft, in particular to a low-altitude composite aircraft. Background technique [0002] The existing tilting quadrotor aircraft includes a fuselage, a first wing, a second wing, a tilting unit and four sets of rotors; The two rods on the surface, and the four rotors are respectively fixed on the four ends of the two rods. The axis of rotation of the rotor is perpendicular to the rod. When the bar is in a horizontal state, the four rotors rotate to provide forward propulsion for the aircraft; when the bar is in a vertical state, the four rotors rotate to provide upward lift for the aircraft. The speed difference between the first rotor and the following two rotors is realized. The first wing and the second wing are respectively arranged on the left and right sides of the fuselage to provide lift when the aircraft is flying. That is, the take-off and landing flight of the aircraft requires the operatio...
