"Yes, where does the wind come from? How is the wind formed in nature?

“In areas with higher temperatures, the volume of air expands, the air pressure increases, and it flows to areas with lower air pressure, which is wind.

"The future engine I envision is to apply this principle.

"Make a cavity in front of the turbine, spray fuel into the cavity and ignite it. This cavity can be called a combustion chamber.

“The air in the cavity combustion chamber is heated, expands, and is ejected rearward at high speed, driving the rear turbine to rotate.

“It is still an internal combustion engine, but instead of a piston internal combustion engine, it is a turbine internal combustion engine.

"No more reciprocating piston motion.

"The fuel in the combustion chamber will continue to burn, hot air will continue to spurt backward, and the gas turbine will continue to rotate.

"In order for the turbine to continue operating, we must continually replenish fresh air and oxygen into the combustion chamber.

“So I opened the duct in front of the combustion chamber and installed a built-in fan that blows air and pressurizes it into the combustion chamber.

“The fan should be driven directly from the turbine drive spindle.

"In this way, the engine structure itself is ready, and the next step is the actual application.

"A small gas turbine is used to drive the main shaft, and an external aircraft propeller is installed in front of the main shaft. The propeller drives the aircraft forward.

"This kind of engine can be called: gas turbine propeller engine.

“You can also enlarge the combustion chamber and the jet nozzle, and rely on the reaction force of the rear jet to push the aircraft forward.

"This can be called: gas turbine jet engine.

“You can also combine propellers and jets to give the aircraft two sources of driving force.

"This can be called: gas turbine fan engine.

“You can also use the spindle to drive wheels or even propellers on ships.

"This kind of thing can be directly called: gas turbine engine."

Zhu Jingyuan entered a state of gushing.

Direct gas turbine technology spoilers turned upside down.

The three forms of jet engines of later generations, as well as the forms of gas turbines for vehicles and ships, are all directly explained.

The craftsmen around him were all surprised when they heard this.

This principle is very simple, but it is also very feasible.

And it is conceivable that the engine structure will be very simple, without a crankshaft and a piston, and the continuous performance will be very good.

In terms of mechanical and power design, the simpler the better.

Because the simpler the design, the higher the power can be obtained.

No one will actively pursue complexity unless they have to.

Zheng Fuguang imagined it in his mind, and then instinctively asked Zhu Jingyuan:

"Your Highness, this idea is very subtle. Why not design it immediately instead of just using it as a future direction?"

Zhu Jingyuan smiled and asked:

"Gong Zheng thinks carefully about how difficult it is to make this thing and how difficult it is to achieve the desired effect."

Zheng Fuguang reacted quickly:

"This is equivalent to an open internal combustion engine, allowing high-temperature gas to directly blow the turbine stage blades. This..."

Zheng Fuguang paused:

"This requires very high materials..."

Zhu Jingyuan nodded slightly and said:

"It may be possible to do it with the current materials, but to get the ideal effect... it's very difficult as you can imagine.

“So it is the direction of future research and development and exploration, first to verify whether the principle is feasible.

“Then… it’s about constantly optimizing the design and improving material performance at the same time.

"This may take a long time, starting in ten years, not even twenty years..."

Contrary to what many people believe, jet engines appeared very early in history.

It is also a product of the second industrial revolution.

In 1903, before the construction of the dreadnought began, and the Wright brothers were still flying their own planes, it had already appeared.

In 1921, before the world's first purpose-built aircraft carrier was launched, the French applied for a jet engine patent.

By the early 1930s, the Soviet Union and the United Kingdom had already produced engine prototypes.

By the late 1930s, the Soviet Union, the United Kingdom, and Germany all began to conduct experiments on aircraft.

Then World War II came.

War, in some cases, will indeed promote the maturity of technology.

But more often than not, it hinders technological innovation.

The war forced the participating countries to focus mainly on existing models and the design and production of conservative and mature models.

Unless we are at the end of our rope like Germany in the late war, we will not try new and uncertain technologies.

Without World War II, those doomsday piston propeller fighters in history may not have appeared.

The early 1940s was supposed to be the era of the "turboprop."

Of course, jet engines are still a bit premature for the current technical level of Zhu Jingyuan and Daming.

Therefore, it is still classified as exploratory and confirmatory research.

Zhu Jingyuan finished arranging the tasks and divided Zheng Fuguang and the craftsmen into groups.

Among the three laboratories, the piston laboratory is the most important and has the most people assigned to it.

Next is the machine laboratory, which needs to complete the application design of aircraft and automobiles, which are relatively independent but urgent tasks.

Finally, there is the turbine laboratory. There are only three people in total, so it can only be regarded as a team.
