"I have read the report you submitted. It seems that all airplanes are using liquid-cooled engines. I want to know why air-cooled engines cannot be used? Cylinders are distributed around a central axis, and the heat is dissipated by the oncoming cold air flow. . And the air-cooled engine is more resistant to damage." The prince was very satisfied with Daimler's performance, so he decided to take the opportunity to show off his aviation knowledge.

"We have thought about this problem. First of all, air-cooled heat dissipation proved to be insufficient. The flight speed is still relatively slow. Therefore, the air volume on the windward side is limited and the heat dissipation effect is also limited. Moreover, if an 8-cylinder air-cooled engine is also used, the front The area will increase a lot, and the flight resistance will be greater. So we still tend to use liquid-cooled engines." Daimler’s ethics is still guaranteed. If you say that fraud is tolerated in order to gain more support and gain more support Yes, but technically, this master cannot give up!

Liquid-cooled engines have higher heat dissipation efficiency and a small frontal area, so lower power can have higher performance. Historically, the European aviation industry generally prefers liquid cooling, especially as a fighter that requires higher agility All of them were powered by liquid-cooled engines. This situation continued until World War II. For example, the British Spitfire, the German bf109, and the air-cooled f190 was forced to switch back to liquid-cooled.

As for why the Americans and Japanese use air-cooling, Japan will not say anything. I didn't get a db601 clean. Many automatic control components eventually became manual... The liquid-cooled engine of the American production version is not as good as that of Europe, not to mention the United Kingdom, and the production version of the v1710 is not as good as the later German db603 and jumo213. (Of course, after the war, some last-generation models still surpassed Germany.)

"It seems that there is still a long way to go to get an air-cooled engine." The prince sighed inwardly.

No matter what, this time the prince is still very satisfied with the Pilot One. The aircraft has a certain practicality, and the next step is to let people see the great role of the aircraft, so that the German government will promote the development of the aircraft industry from top to bottom. , Instead of throwing energy on the airship, the airship is now easy to use. It has an overwhelming advantage in terms of stagnation time, range, cargo capacity, and flight altitude, but its potential is limited!

The words are divided into two sides. The task that the prince explained must be completed. Major General Schmidt soon brought a technical team and made improvements according to the requirements of Daimler and others. At the beginning, the technicians brought it. It is a brand new mg1900 machine gun. This machine gun is fixed beside the left wing and is equipped with a ring frame. The machine gun can slide on the frame and use a saddle-shaped drum for ammunition.

To be honest, it is not easy for pilots to control the aircraft under the current circumstances, and it is not easy to control machine guns on a swaying aircraft. Shooting ground targets on an unstable aircraft is almost impossible. Then the technicians made improvements. , The fire switch is integrated into the operating handle, the machine gun is fixed on one side of the wing, and a simple sight is installed. Although it is still not very useful, but at least it is like that, giving people a sense of tallness...

And this time I used a dynamic shooting method. The Voyager 1 flew over at an altitude of 100 meters, and another car equipped with a video camera was moving in parallel. When the plane flew over 200 meters from the target, the pilot pulled the trigger. In a few seconds, all 200 incendiary bombs will be lit up! And the small wooden house as the target turned into a sea of ​​flames in the dense bullet rain!

"It's great, very good." The prince was very satisfied with the photos on the table. A huge figure passed by in the air, spraying a deadly tongue of flames at a room next to him, in just a few seconds. , This room becomes a torch. Of course, the help of combustible and explosive materials in the house is definitely indispensable...

"In fact, even if there is no bullet hit, the house will still burn." Afterwards, Baron Daimler wrote in his diary...

As for the subsequent ground bombing, there were also many problems. "On a swaying plane, unless I am as agile as a monkey, I can only use my mouth to open the grip of the grenade and throw it down. The technical team also tried to install a bomb rack to solve the problem, which really freed my hands. But it’s a pity that too powerful bombs are a problem for the aircraft itself. I once dropped a 50kg bomb at a height of 150 meters. The violent impact after the explosion almost made the aircraft out of control!" , Admiral Lane, who was known as a lion in the sky, recalled his bombing experience in this way.

This is definitely not a good experience. The fragility of the first-generation aircraft is vividly demonstrated in the test! The wing of the aircraft is too large, which directly reduces the structural strength. At the same time, it does not have a complete closed body, and there is no strong enough support inside. Throwing a grenade is fine, and throwing a mortar shell is also okay~lightnovelpub.net~ If it is more powerful, there will be a problem. After all, violent explosions and flying shrapnel can completely break the slowly flying "book shelf" in the air into pieces.

However, after the stunt photographer joined, everything changed in the lens. In the lens, the plane flew in a straight line through a piece of water, and the dark objects were thrown down. The water column soars into the sky, which can definitely give people a refreshing feeling. This is a cross-epoch achievement.

Even when it was statically displayed on the ground, someone installed a set of radio communication equipment on the plane. Of course, due to weight and operability issues, this system was almost unusable in the air. At least one person could not drive the plane while driving. Report. And now there is no two-seater plane... But you might as well see the huge role and development potential of aircraft from it!

A large number of photos were collected after screening. The prince also wrote a letter of recommendation. This letter was not for the Kaiser. After all, the Kaiser did not know much about military affairs and was not a front-line staff member. It's still a little troublesome to do. The prince needs to send these materials to someone who can really see the future of aviation development and is capable of accomplishing it! And this person is the famous German Chief of Staff Mochi, the current quartermaster!

The prince gave this information to Xiao Maoqi for a reason. It was not only that the two had a similar attitude towards the Schlieffen plan and won each other's favor, nor that this buddy was the future chief of staff, but because he was One of the few people in the senior German army who really saw the role of aircraft!
