The graph carries eddy gush engine to play
Aviation engine is called the bright phearl on industry, this word a bit truly. The biscuit in an engine contained hundreds lamina, minutely rotate speed is as high as thousands of to turn on 10 thousand turn, it is the high temperature that wants on 1000 degrees to bear more. Make sure below so harsh environment successive movement counts a hour even, reach thousands of service life of on 10 thousand hours, its difficulty cans be imagined.
And be in recently, transmit a good news however. An enterprise achieves a breakthrough one after another, released a series of eddy gush / eddy fan engine, its product thrust covered 1000 kilograms of stage all the time from 60 kilograms of class, can say very rich, this enterprise is institute of hot physics of project of Chinese Academy of Sciences. Probably somebody is met sniff, not be big contain path engine of for military use of bigger perhaps than eddy fan engine thrust, it doesn't matter is very curious. Actually we lack this kind of engine likewise urgently.
The graph is homebred medium or small eddy fan engine
Cite a very simple case, tens of kilogram the eddy fan engine of level can be used in missile above, at present Chinese cruise missile perhaps flies boat type missile, as long as it is jet-propelled dynamic, great majority still is using eddy gush motor. Eddy gush engine has an advantage, make namely simple, the demand is not very high. But eddy gush engine has a defect to be highlighted likewise, this is excessive consumption of fuel and oil. And the advantage of eddy fan engine is rather, the province is oily but complex. If missile uses eddy fan motor will huge raises range, immediate even change fights means.
The engine with heating power at present newest place is 190 kilograms of class take engine of gush of thrust augmentation eddy, this has specific aim very. Engine of general thrust augmentation is without an accident basically is used to opportunity for combat, in where can be the engine that can you be so small thrust used? The answer is supersonic speed target drone. Present target drone great majority is subsonic speed, although ultrasonic also has, but mark of basic Shanghai Airline is inflexible, can use only should do target drone fire, unmanned aircraft is being changed to accompany experienced respect China in intelligence is a blank from beginning to end. One can undertake subsonic speed motor-driven holds the target drone that has capacity of supersonic speed flight concurrently to be opposite the sense is great for China.
The graph is machine of small-sized jet-propelled official business, future plaza of motor of a ton of class cannot set limit to
There also is contribution on the eddy fan engine that heating power is in a ton of class in addition, this demand is bigger. Man-machine is not had when checking boat of dozen of one body length at present basically give priority to with piston engine, cruise speed does not exceed 200 kilometers commonly horary. Such speed makes his extremely easy by intercept, and the time that hurries to war zone to also want to expend monitor, cannot answer a few time sensitive model target. If change engine of the fan that do eddy, its cruise rate can rise 800 kilometers to control, huge improves its tactics performance.
In addition engine of a ton of class is above civil aviaton also have huge demand, machine of official business of a few small-sized jet-propelled basically is this thrust grade. Besides heating power is in axis of small small-sized eddy and gas turbine respect to also have quite make a contribution. Finished early or late much model the development of form a complete set of small-sized eddy axis of unmanned helicopter, the development that launched 30MW gas turbine works. As persistent investment, place of prospective heating power is sure to become one of industry of Chinese aviation motor dazzling star.
