Chapter 72 Aero Engines (Clicks, Recommendations, Collections)
"Can it be started?" Ciric asked. Pen "Fun" Pavilion www.biquge.info
"Absolutely!" Fritz stepped forward, flipped the starter lever over, unscrewed the electric door, and kicked it hard.
Ciric can ride, but Ciric can't start, in later generations, all of them are electric starts, this way of pedaling, is skillful.
Pale blue smoke came out of the exhaust pipes on both sides, spewing backwards with the sound of the humming engine.
Ciric twisted the throttle twice, and the engine roared, and then, pinching the left clutch, Ciric's foot stepped on the gear lever.
Slowly release the clutch, follow the right hand to tighten the throttle, and the R-75 motorcycle rumbles into action!
Colonel Ciric is simply an all-rounder, no one has taught Ciric how to ride a motorcycle, especially this three-wheeled motorcycle with a sidecar, and Ciric can actually drive away!
Pretty stylish, right? In later generations, as an absolute fan of World War II, Ciric once rode the Yangtze River 750, although the prototype was not R75, but R71, after all, there are still many similarities.
And now, riding this motorcycle, Ciric has fully integrated into this era, Germany's military production capacity is absolutely strong enough, and the only factor limiting them is resources!
Now that Cirek has crossed over and become Hitler's most trusted subordinate, of course he wants to change all that!
Now, a lot of revelations have changed, this motorcycle, which was supposed to be produced in 40 years, is now, years ahead!
Stepping on the brakes, pinching the front brake, a huge force came, and the BMW R75 came to a rapid stop.
The front wheels of this car are mechanically braked, and the rear wheels are hydraulically assisted brakes, which is quite easy!
Watching Ciric come back in a circle, everyone in BMW knows that there is absolutely no problem with the finalized production of this motorcycle! In this way, BMW will also usher in the peak of development!
"Good performance." Ciric got out of the car and said: "When the test is completed and handed over to the military for acceptance, the military can order a thousand units first." ”
One thousand, just an initial number, in the entire World War II, there were sixteen thousand motorcycles of this model alone, and there were other models, as well as motorcycles of other companies, which were active on the front lines of World War II.
"Colonel Ciric, we have another idea about this motorcycle." "It was a prototype of this motorcycle, and then it was changed to a tracked chassis for better performance," says Frieze. ”
Half-track construction! Wheels in the front, tracks in the back, this structure, which was once quite popular in the army of Germany!
Of course, Ciric knows that this structure is not actually very advanced, and later generations have eliminated all this structure, which is an example, but now, with only a small number of improvements, it can have better performance, and of course it can be tried.
"We agree in principle, however, this is not a model proposed by the military, so there is no need to think about the military's research and development expenses." Ciric made it clear.
"Okay, we, BMW, bear the R&D costs ourselves." Said the head of BMW, Franz Josef Pap.
As long as it gets a steady stream of orders from the army, BMW will be able to have a good financial balance and develop new models on its own, which is also quite easy.
And then Ciric's words made BMW even more overjoyed.
"As a professional aircraft engine manufacturer, BMW must continue the tradition of designing better and more powerful aircraft engines." "The empire needs BMW's aero engines," Ciric said. ”
Aero engines! This has always been BMW's main business!
BMW has never given up on aero engines over the years! They have been developing all the time, but unfortunately, they can only be pre-researched, or sold abroad, such as the Soviet Union, island countries, etc., and 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'll definitely work hard." Papu said.
"Also, in a few days, the company will send a few people to go out with me." Ciric said.
"Where to go?" Papu was stunned.
"When we go to the UK, we negotiate with Rolls-Royce, and if the price is right, we will buy their Merlin engines, and Mercedes-Benz will also send people, and we will go together." Ciric said.
Merlin Engine!
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, while Germany and Britain were quite advanced in the early days.
The DB600 series liquid-cooled engine is a Mercedes-Benz classic, and the 601 is installed on various 109 models as the queen engine of the 109, and the BF110 also uses this engine.
The most advanced of this engine is direct fuel injection, powerful power, compact construction and Zenith technology, which is in the leading position in Europe.
It's a pity that due to the limitations of resources and materials, the two-stage supercharger of the German engine could not be made, and 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 queen engine of the 190 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 strong, and the powerful engine and powerful firepower make the butcher's bird FW190.
The dispute between liquid and air cooling during World War II also existed in Germany, but Germany produced both engines at the same time.
And in the UK, there is also an advanced engine, which is the power of the Spitfire, the Merlin engine! This engine has advanced performance, and even later, even the United States has introduced the patented production of this engine, when World War II just began, the American aero engine was 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 their own funds to develop a 27-liter displacement engine, named Merlin engine.
This is an 820 kilowatt 12-cylinder engine, which was only installed for the first time in October 33 in history.
The original Merlin was not very reliable, suffering from cylinder cracking, coolant leakage, cam wear, and bearing failure, but after meticulous modifications, it was improved one by one, and with excellent performance, this engine began to be widely adopted by the RAF aircraft.
