Embodiment Construction
[0010] Such as figure 1 As shown in the schematic diagram of the overall layout, the electric low-noise short take-off and landing wing aircraft according to an embodiment of the present invention includes a fuselage (1), a front wing (2), an end plate (3), a rear wing (4) and Vertical tail (5). The front wing (1) is a straight trapezoidal wing positioned above the fuselage, and the rear wing (4) is a forward-swept upper anti-wing wing positioned below the fuselage. The wingtips of the front wing (2) and the rear wing (4) are connected together by the end plate (3) to form a box-shaped structure, which has good structural strength and the overall structure is light in weight. In addition, this arrangement also makes the motor ( 10) and the propeller (11) are placed high, so that the layout can be used as an amphibious layout, and the lower blade of the fuselage (1) is correspondingly changed to the bottom form. The control surface of the aircraft includes: a rudder (6) posit...

The invention provides a motor-driven low-noise short-distance taking-off and landing wing-connected aircraft. The motor-driven low-noise short-distance taking-off and landing wing-connected aircraft is characterized by comprising an aircraft body (1), front wings (2), rear wings (4), end plates (3) and vertical fins (5), wherein the front wings (2) are flat and straight ladder-shaped wings, and are positioned on the upper part of the aircraft body; the rear wings (4) are sweep forward upper reverse aircraft wings, and are positioned below the aircraft body; and the end plates (3) are used for connecting wing tips of the front wings (2) and the rear wings (4) together so as to form a case-shaped structure. The motor-driven low-noise short-distance taking-off and landing wing-connected aircraft provided by the invention has the advantages and beneficial effects that the excellent structure performance of a wing-connected-type aircraft is inherited; the short-distance taking-off and landing capabilities are realized through slide flow deviation power; a motor-driven airscrew thrust device and a power generating unit arranged in the tail of the aircraft lower the whole noise level of the aircraft effectively; and the backup design of a power system enables the aircraft to have extremely high reliability, and the safety in short-distance taking-off and landing and cruising is ensured. Each technique adopted by the invention has high maturity, and is integrally simple, and easy to achieve, and the construction and using costs are low.
Description
technical field [0001] The invention relates to an electric low-noise short-distance take-off and landing wing aircraft, which belongs to the technical field of fixed-wing aircraft design in aviation aircraft. Background technique [0002] There are obvious advantages in aerodynamics and structure of the aircraft with wing layout. In terms of aerodynamic characteristics, the layout of the wings effectively reduces the induced drag of the aircraft, and often has a high lift-to-drag ratio, so it can obtain efficient cruise performance, save fuel or increase the range. From a structural point of view, the box-shaped structure of the wing layout has good overall strength, which reduces the requirements for local structural strength, greatly saves the structural mass, and thus increases the payload. However, for conventional aircraft, the aerodynamic and structural performance can be improved in other ways, but for the more important take-off and landing performance and noise co...
