Embodiment Construction

[0024] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0025] Such as Figure 1-3 As shown, they are the side view, top view, and front view of the light aircraft respectively. Since the main view reflects the characteristics of the aircraft most comprehensively, the figure 1 Explain for the master. This light aircraft comprises fuselage 1, and as traditional aircraft, fuselage front end is cabin 11, and the rear end of fuselage is provided with empennage 2, and aircraft also comprises a power plant (figure not shown) and a propeller 5 connected with it . Different from traditional aircraft, the tail of this aircraft uses a V-shaped tail ( figure 2 , 3 is clearly shown in ), and in cooperation with it, a propeller 5 is erected above the nacelle 11 through a connecting part, and the specific height from the nacelle should ensure that the...

Abstract

The invention discloses a light airplane. The airplane comprises an airplane body, a first power device and a first propeller connected with the first power device, wherein the front end of the airplane body is provided with a cabin; the rear end of the airplane body is provided with a tail wing; the tail wing is V-shaped; the first propeller is arranged above the cabin through a first connecting part; and airflow which is generated when the first propeller rotates can penetrate through the middle airspace of the V-shaped tail wing. According to the airplane, the power devices which are serially arranged forward and backward are arranged on a wing platform higher than the axis of the airplane body, and the propellers are only arranged at front and back ends of a streamline body connected with the power devices which are serially arranged forward and backward, so that the airflow obstructed region of the front propeller of the airplane body is greatly reduced, and the push-and-pull efficiency is improved; and simultaneously, the interference resistance of the airplane body and the wing are reduced, the wing efficiency is improved, and the influence of operation sensitivity on a control plane in the process of changing the power of the propellers is reduced.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a light aircraft. Background technique [0002] There are several types of traditional light aircraft at present. One is that the power unit and the propeller are arranged on the front end of the fuselage, so that most of the propeller airflow is in the shadow anti-condensation area of ​​the fuselage, which reduces the propulsion efficiency of the propeller and increases the resistance of the fuselage. The other is that the power units are symmetrically arranged on the wings on both sides of the fuselage. If one of the power units is damaged and cannot output power, it will inevitably cause the overall power distribution of the aircraft to be uneven, which will increase the difficulty of control and affect the quality of the aircraft. normal flight. [0003] There is also a light aircraft whose tail is horizontal or vertical, mostly in the tail of the propeller airflow. Because the rot...
