Description
[technical field]
The utility model relates to unmanned plane art field, is specifically related to the twin-engined device of a kind of fixed-wing unmanned plane series type.
[background technology]
Along with development in science and technology, unmanned plane highlights day by day in dual-use effect, and the power mode of current fixed-wing unmanned plane is two kinds, and one is front pull-type power, and two is back-pushed power.There are the following problems for traditional single-shot unmanned plane: traditional unmanned plane is owing to using single-shot life as propulsion source, thus its power mode does not have aerial restarting ability substantially, driving engine long working probably breaks down speed of turning round, or directly stop working, driving engine puts out suddenly aircraft and to run out of steam crash, cause the loss of airborne equipment, serious thing of also likely hurting sb.'s feelings, poor reliability, particularly High aititude operating environment, engine off probability is higher, and the safety of unmanned plane can not get ensureing.
[utility model content]
The purpose of this utility model is defect for prior art and deficiency, there is provided a kind of structure simple, the twin-engined device of a kind of fixed-wing unmanned plane series type reasonable in design, easy to use, it adopts the power mode pulled in front and others push behind, use coaxial series type two-engined layout structure, when an engine off, another driving engine also can ensure normal flight operation, greatly improves the safety and reliability of unmanned plane operation.
The twin-engined device of a kind of fixed-wing unmanned plane series type described in the utility model, it is made up of F/F, rear-mounted engine, front engine mounting bracket, rear engine mounting bracket, front pull-type screw propeller and pusher propeller; Described front engine mounting bracket and rear engine mounting bracket horizontal symmetrical are arranged on front part of a body and afterbody; Described front engine mounting bracket and rear engine mounting bracket are respectively arranged with F/F and rear-mounted engine; Described F/F and rear-mounted engine are separately installed with front pull-type screw propeller and pusher propeller; The both ends horizontal that described F/F and rear-mounted engine are arranged on body is opposed.
After adopting said structure, the utility model beneficial effect is: the twin-engined device of a kind of fixed-wing unmanned plane series type described in the utility model, it adopts the power mode pulled in front and others push behind, use coaxial series type two-engined layout structure, when an engine off, another driving engine also can ensure normal flight operation, greatly improves the safety and reliability of unmanned plane operation.

Accompanying drawing described herein is used to provide to further understanding of the present utility model, forms a application's part, but does not form improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is the utility model structural representation;
Description of reference numerals:
1, front pull-type screw propeller; 2, F/F; 3, front engine mounting bracket; 4, body; 5, rear engine mounting bracket; 6, rear-mounted engine; 7, pusher propeller.
[detailed description of the invention]
The utility model is described in detail, illustrative examples wherein and illustrate and be only used for explaining the utility model below in conjunction with accompanying drawing and specific embodiment, but not as to restriction of the present utility model.
As shown in Figure 1, the twin-engined device of a kind of fixed-wing unmanned plane series type described in this detailed description of the invention, it is made up of F/F 2, rear-mounted engine 6, front engine mounting bracket 3, rear engine mounting bracket 5, front pull-type screw propeller 1 and pusher propeller 7; Described front engine mounting bracket 3 and rear engine mounting bracket 5 horizontal symmetrical are arranged on body 4 front portion and afterbody; Described front engine mounting bracket 3 and rear engine mounting bracket 5 are respectively arranged with F/F 2 and rear-mounted engine 6; Described F/F 2 and rear-mounted engine 6 are separately installed with front pull-type screw propeller 1 and pusher propeller 7; The both ends horizontal that described F/F 2 and rear-mounted engine 6 are arranged on body 4 is opposed.
In the utility model, there are front engine mounting bracket and rear engine mounting bracket body both ends horizontal is opposite disposed, front engine mounting bracket and rear engine mounting bracket are separately installed with F/F and rear-mounted engine, this F/F, rear-mounted engine adopt coaxial inline configuration layout, and it is flat opposed structure that this F/F, rear-mounted engine are arranged on body two ends.
Principle of work of the present utility model is as follows: twin-enginedly when taking off provide power, significantly shorten take off distance, cruise in the air operation time, monomotor work can meet job requirements, another is standby, at operation engine breakdown or when stopping, can start at any time and be switched to the continuation operation of standby driving engine or make a return voyage.Increase substantially the safety and reliability of unmanned plane operation.
The utility model and single-shot unmanned plane layout structure contrast as follows:
Compared to the layout structure of single-shot unmanned plane, take off distance of the present utility model is shorter.Adopt the fixed-wing unmanned plane of single-engined same specification, for meeting equal take off distance, need to adopt high-performance driving engine, the monomotor mode of operation compared to two, also just mean and need higher oil consumption aloft, had a strong impact on the cruise duration of unmanned plane; And be reduce oil consumption, promote cruise duration, by the power reduction of driving engine, just mean farther take off distance and less mission payload.The utility model adopts the problem that the two layout sent out of coaxial series type then efficiently solves take off distance, continuation of the journey oil consumption, take-off weight can not be taken into account simultaneously.
Feature of the present utility model is as follows:
1) safe and reliable, an aerial engine off, another can work on;
2) effectively take off distance is shortened;
3) mission payload is larger;
4), while ensureing take off distance, reduce aerial oil consumption, add cruise duration.
The twin-engined device of a kind of fixed-wing unmanned plane series type described in the utility model, it adopts the power mode pulled in front and others push behind, use coaxial series type two-engined layout structure, when an engine off, another driving engine also can ensure normal flight operation, greatly improves the safety and reliability of unmanned plane operation.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
