Chapter 361 (1/2)

Wang Bin and sun Lao first came to the laboratory for the research and development of pulse detonation engine. At the same time, this technology is also the research and development focus of Tiangong technology in terms of new technology.

After all, compared with ion engine and atomic engine, it is easiest to realize this technology with the current material technology of Tiangong technology.

Moreover, when Tiangong technology develops a real manned aircraft, it is necessary to start the research and development of aerospace aircraft, and the research and development of aerospace aircraft must use engines that can be used both in the atmosphere and in space. Pulse detonation engine is definitely the best choice for Tiangong technology at present.

Of course, they can also choose other aspects of engine R & D work, such as variable cycle ramjet, but these engines have complex technology and high technical difficulty, and have very high requirements for processing equipment. The most important thing is that in terms of safety, they are far inferior to pulse detonation power generation, as well as the requirements for materials, It is not lower than that of pulse detonation engine.

Therefore, now that they have made great achievements in pulse detonation engine, it is not necessary for them to re develop variable cycle ramjet. In this regard, the government has also been developing and achieved good results. If Wang Bin and their Tiangong technology re develop, it will undoubtedly waste funds and scientific research resources.

You know, with the official approval of the deep space star chain plan of Wang Bin and Tiangong technology, the funds and scientific research resources that Wang Bin and Tiangong technology will invest in the future are very huge, a little waste, which is a great damage to Tiangong technology.

As Wang Bin, sun Lao and others came to the laboratory, the first thing to see was that there were many pulse detonation engines in the laboratory.

The diameter of these engines is generally small. The largest diameter of the smallest engine is only less than 50 mm, while the nozzle of the engine is smaller, only less than 20 mm. At the same time, the self weight of this engine is only a few kilograms.

However, although the diameter and weight of this engine are small, the length of this engine is not short, with an overall length of more than one meter. At the same time, although the nozzle of this engine is also small, its thrust is not small, reaching hundreds of kilograms. It can be said that this engine also has certain practicability, especially when used in small Aerospace unmanned aerial vehicles, Even more so.

After all, when the ramjet is used in the atmosphere, when the speed reaches Mach 2.2 or above, its fuel consumption will be much less than that of engines of the same level. As for the universe, its fuel consumption is several levels less than that of rocket engines of the same level.

In addition, there are many types of pulse detonation engines in the whole laboratory. These engines are not the same in size and shape, ranging from large to small. However, the largest of them has a maximum diameter of no more than 1200 mm, and the nozzle diameter is no more than 500 millimeters.

At the same time, among these pulse detonation engines, the thrust and specific impulse are also large and small. The thrust ranges from hundreds of kilograms to several tons. In terms of specific impulse, there are about ten times that of ordinary aviation engines, and there are also engines that reach more than ten times that of ordinary aviation engines.

Of course, in addition to these successfully developed engines, there are more failed products in the whole laboratory. After all, even with good materials, it is impossible to develop a pulse detonation engine with excellent performance at one time.

However, fortunately, with the increase of R & D time for pulse detonation engine, R & D personnel have a more in-depth grasp of various data of pulse detonation engine, and the success rate of its R & D has greatly increased. Until now, they have rarely failed and the engine can not work.

These engines, except for a few engines, are considered to be truly successful in research and development, such as the five ton pulse detonation engine that has just been successfully developed.

Other engines, seen by these people in the laboratory, are actually just experimental products.
