Abstract
The utility model provides an aircraft. The utility model comprises an aircraft body of which the bottom part is provided with forward flow chord waves, and the cross section of each forward flow chord wave forms a sine wave shape. The bottom part of the aircraft body is also provided with a concave balance chamber in which balance wings are arranged, and an air inlet of an engine is arranged at the side part of the balance chamber. The utility model has the characteristics of simple structure, stable takeoff and landing and small energy consumption. The utility model is suitable for low speed aircraft with short range takeoff and landing.
Description
Technical field
The utility model relates to a kind of aircraft of low speed short take-off and landing (STOL).
Background technology
Traditional vertical takeoff and landing or short take-off and landing aircraft as helicopter, short take-off and landing fixed wing aircraft etc., are to utilize driving engine to make air-flow downward, thereby realize vertical or short take-off and landing, and this mode need consume bigger energy, and complex structure; Simultaneously on on-fixed landing platform, during landing, often form bigger wind sand and dry sound.
The utility model content
The utility model is at the deficiencies in the prior art, and a kind of simple in structure, landing is steady, energy consumption is little a kind of aircraft is provided.
The purpose of this utility model is achieved in that a kind of aircraft, comprises body, and wherein: be provided with following current string ripple at organism bottom, the cross sectional shape of this following current string ripple is a sinusoidal waveform; Also be provided with the balance thorax of a concavity at organism bottom, in the balance thorax, be provided with balance wing; The admission port of driving engine is arranged on balance thorax sidepiece.
The wave height of the following current string ripple described in the utility model is good with 2% of body width.
Balance thorax in the utility model can adopt circle or stream line pattern.
The utility model is owing to adopt said structure, utilizes air-flow to down and the aircraft effect of float makes steadily landing of aircraft, simplified the structure of aircraft, reduction landing energy consumption, be particularly suitable for low speed (less than 300 kms/hour) aircraft.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the utility model is described in further detail.
Fig. 1 is wherein a kind of structural representation of specific embodiment of the utility model;
Fig. 2 is the upward view of Fig. 1;
Fig. 3 is the right elevation of Fig. 1.
The specific embodiment
As shown in Figure 1 to Figure 3, a kind of aircraft of the present utility model comprises body 1, is provided with following current string ripple 2 in body 1 bottom, and the cross sectional shape of this following current string ripple 2 is a sinusoidal waveform; The wave height of following current string ripple 2 is 2% of body 1 width; Also be provided with the balance thorax 3 of a concavity in body 1 bottom, balance thorax 3 is circular; In balance thorax 3, be provided with balance wing 4, be used for the flight balance of controlling aircraft.The admission port of two driving engines is arranged on balance thorax 3 both sides.
Claims (3)
1. an aircraft comprises body (1), it is characterized in that: be provided with following current string ripple (2) in body (1) bottom, the cross sectional shape of this following current string ripple (2) is a sinusoidal waveform; Also be provided with the balance thorax (3) of a concavity in body (1) bottom, in balance thorax (3), be provided with balance wing (4); The admission port of driving engine is arranged on balance thorax (3) sidepiece.
2. a kind of aircraft according to claim 1 is characterized in that: the wave height of described following current string ripple (2) is 2% of body (a 1) width.
3. a kind of aircraft according to claim 1 and 2 is characterized in that: balance thorax (3) is circle or stream line pattern.
