Chapter 72： Aircraft engine

"Can it be activated?" Cyric asked.

"Of course you can!" Fritz stepped forward, turned the start lever over, unscrewed the switch, and then gave him a hard kick.

Cyric can ride, but Cyric will not start. In the later generations, all of them are electrically activated. This way of pedaling is tricky.

The exhaust pipes on both sides of 　　, light blue smoke came out, following the sound of the humming engine, it sprayed out backwards.

Cyric twisted the accelerator twice, and the engine roared, then, pinching the left clutch, Cyric's foot stepped on the gearshift lever.

slowly loosened the clutch, followed by twisting the accelerator with his right hand, and the R-75 motorcycle started booming!

Colonel Cyric is simply an all-rounder. No one has taught Cyric how to ride a motorcycle, especially this kind of three-wheeled motorcycle with a sidecar. Cyric can actually drive around!

is very cool, right? In later generations, as an absolute fan of World War II, Cyric once rode the Yangtze 750. Although the prototype is not R75, but R71, after all, there are still many similarities.

And now, riding on this kind of motorcycle, Cyrenk has completely integrated into this era. German military production capacity is absolutely strong enough. The only factor that limits them is resources!

Now, Cyric has passed through and became Hitler's most trusted subordinate. Of course he wants to change all of this!

Now, many revelations have changed. This kind of motorcycle should have been produced in 40 years, but now, it has been several years in advance!

stepped on the brake and pinched the front brake, a huge force came, and the BMW R75 stopped quickly.

The front wheels of this car are mechanically braked, and the rear wheels are hydraulically assisted brakes, which is quite easy!

Looking at Cyrek back in a circle, everyone at BMW knows that there is absolutely no problem with this type of motorcycle in finalized production! In this way, BMW will also usher in the peak of development!

"Performance is good." Cyric got off the car and said, "When the test is completed and it is handed over to the military for acceptance, the military can first order one thousand."

One thousand is only an initial number. In the entire World War II, there were 16,000 motorcycles of this model alone. Other models and motorcycles from other companies were active on the front lines of World War II.

"Colonel Cyric, we have another idea about this kind of motorcycle." Fritz said: "Take this kind of motorcycle as a prototype, and then change it to a tracked chassis for better performance."

half track structure! The front is the wheel and the back is the track. This structure was once quite popular in the German army!

Cyric of course knows that this kind of structure is actually not very advanced. It is an example that this kind of structure will be eliminated in future generations. But now, only a small amount of improvement is needed to have better performance, and of course it can be tried.

"We agree in principle, but this is not the model proposed by the military, so don't think about the military's research and development expenses." Cyric said very clearly.

"Okay, we, BMW, bear the R&D expenses ourselves." said Franz Joseph Papp, the head of BMW.

As long as it receives a steady stream of orders from the military, BMW will be able to have a good financial income and expenditure, and it will be quite easy to develop new models on its own.

Then Cyric's words made BMW even more overjoyed.

"As a professional aircraft engine manufacturer, BMW must continue the previous tradition and design better and more powerful aircraft engines." Cyric said: "Empire needs BMW aircraft engines."

Aircraft engine! This has always been the main business of BMW!

BMW has never given up on aero engines in these years! They have been developing, but unfortunately, they can only be pre-researched, or sold abroad, such as the Soviet Union, island countries, etc., but in Germany, there are almost no orders.

Now, Germany is finally going to vigorously develop its military! It is conceivable that in the future, there will be a large number of orders, rolling in!

"We will definitely work hard." Papp said.

"Also, in a few days, the company will send some people to go out with me." Cyric said.

"Where to go?" Papp was taken aback.

"When we go to the UK, we will negotiate with Rolls-Royce. If the price is right, we will buy their Merlin engine. Mercedes-Benz will also send someone, and we will go together." Cyric said.

Merlin engine!

The World War II in history is also an era of continuous eruption of various technologies!

When it comes to aero engines, the United States stepped aside, and Germany and the United Kingdom were quite advanced in the early stages.

DB600 series liquid-cooled engine can be described as a classic Mercedes-Benz, 601 is installed as the queen engine of 109 on various 109 models, and BF110 also uses this engine.

The most advanced engine of this kind is direct fuel injection With its powerful power, compact structure and Zenith Star technology, it is in the leading position in Europe.

Unfortunately, due to the limitations of resources and materials, the second-stage supercharger of the German engine could not be made. By the end of World War II, there was a big gap in high-altitude performance.

At the same time, BMW's 801 series air-cooled engine is also quite advanced, especially the BMW 801, as the 190's queen engine, is powerful, and it also uses direct injection technology and a supercharger similar to the 601.

Moreover, with a large number of cylinders and a large displacement, the 801's explosive power is quite powerful. The powerful engine and powerful firepower have made the Butcher Bird FW190.

The battle between liquid cooling and air cooling during the Second World War also occurred in Germany, but Germany produced both engines at the same time.

In the United Kingdom, there is also an advanced engine, the power of the Spitfire, the Merlin engine! This engine has advanced performance. Even later, even the United States introduced patented production of this engine. At the beginning of World War II, American aviation engines were not advanced and there were many technical problems.

In this era, Rolls-Royce is also a veteran of aero engine development. When they realized that the 21-liter Kestrel engine could no longer meet the requirements of future aircraft development, they decided to raise funds to develop a 27-liter displacement. The engine is named Merlin engine.

This is a 820-kilowatt 12-cylinder engine. It was only installed and tested for the first time in October 33 in history.

The reliability of the original Merlin was not high. It was plagued by cracked cylinders, coolant leakage, cam wear, and bearing failure. After careful modification, it was improved one by one. With excellent performance, this engine started It is widely adopted by the Royal Air Force aircraft.
