It goes without saying why we need to change places for test flights.
Building prototypes allows pilots to study and learn the principles of aircraft flight, and pilots also use them as model toys.
But this thing really wants to fly, and there is a pilot driving it... Once or twice, maybe the pilot Yingjiang won't be suspicious, but over time, he will inevitably want to find out what Wang Xuexin is doing.
In addition, Wang Xuexin will use this thing on the battlefield in the future, and the Yingjiang pilot will quickly guess how this "high-precision rocket" was developed.
Yingjiang must not let Yingjiang know about missiles first, otherwise Wang Xuexin's plan of "overtaking in corners" and "asymmetric competition" will all come to nothing.
The test flight site is located at a test site ten kilometers away from the airport.
There used to be an abandoned small airport left by the stubborn army here... Before the start of the Anti-Japanese War, the stubborn army still had many small airports like this, but these small airports were basically playgrounds for dignitaries, or warlords to coax women.
A place of joy and exclamation.
After the outbreak of the Anti-Japanese War, these small airports were the first to be bombed by the Japanese air force, and were abandoned by the stubborn troops not long after.
At this time, the airport was overgrown with weeds, and there were still many craters left by Japanese bombs, as well as the wreckage of several old planes, but they were only vaguely visible...the valuable iron or parts had long been dismantled by the people.
After exchanging money, only worthless fragments were left and thrown all over the floor.
As soon as Wang Xuexin and others got off the car, Professor Su immediately directed the guards to remove the tracks from the car and assemble them on the ground.
To be precise, this track should be called a launch pad.
Just like rockets have launchers, "high-precision rockets" of course also have launchers.
Even though this launcher is simple, it is just two rail-like things pointed at an angle towards the sky, but it actually has a lot of knowledge...
First of all, this can increase the range of "high-precision rockets".
The "high-precision rocket" comes with only an extended rocket engine on the tail... If the research is successful, Wang Xuexin plans to increase the number of rocket launchers to two, three or even four, so as to increase its range.
.
The thrust of this rocket engine is not enough to push the prototype into the air... When taking off, an airplane often requires a lot of thrust and consumes the most fuel, because this process requires taking off in a short distance, that is, reaching flight speed from a stationary state in a short time, so
The whole process requires afterburner.
Taking the Boeing 747 as an example, it consumes 5 tons of fuel for one takeoff, and this amount of fuel is enough to fly in the air for half an hour.
The same principle is applied to the prototype fuselage of the "high-precision rocket". If it relies entirely on the rocket engine it carries... I am afraid that all the fuel will only be enough to lift it into the air.
This is obviously not possible.
So we had to add this launcher, a launcher with a total length of 48 meters, and then eject the prototype aircraft like an aircraft carrier ejecting an aircraft into the air.
Professor Su doesn't feel much about this yet, because his research field is mainly machinery and he is a layman in this area.
But He Zhimin understood the significance of this launcher. When he looked at the drawings, he couldn't help but sigh: "This is simply a genius design. Ejecting the aircraft into the air... it uses the power of land to boost the prototype as much as possible.
The fuel consumption of the prototype can also be reduced, and the weight of the prototype aircraft can be reduced to carry more fuel, which achieves the result of achieving a longer range with the least amount of fuel!"
Then He Zhimin said to Professor Su with a suspicious face: "Lao Su, I don't think this is something that Yingjiang technicians can design. I have studied at Yingjiang for many years and have never seen or even heard of this."
technology!"
Professor Su laughed: "Lao He, just because you haven't seen or heard of it, it doesn't mean that Yingjiang doesn't exist, they just didn't let you know!"
He Zhimin thought for a while, then shook his head and said, "No, it's impossible! You don't know Yingjiang's style of doing things. If they had such a good design, they would have produced it and used it on the battlefield long ago!"
Professor Su was stunned for a moment, and felt that what he said to Zhimin was right. Yingjiang worked vigorously and resolutely no matter what he did, and his production speed was astonishingly fast.
Professor Su and He Zhimin are right in this regard.
The eagle sauce at this time was different from the modern eagle sauce.
Modern Yingjiang is a person who has been pampered in a superior life for a long time and has been raised to be lazy. No matter what he does, he is inefficient or extremely inefficient.
At this time, Yingjiang was in the era of the industrial explosion, and the people were hardworking and willing to endure hardships. During World War II, they even set a record of launching an aircraft carrier per week on average.
Under such circumstances, who would believe that Yingjiang had such a skill but was bullied by the Japanese on the Pacific battlefield and had to use it up?
You must know that this kind of "high-precision rocket" is also very valuable on warships. It is a long-range strike weapon.
Professor Su frowned and said, "Then, if it wasn't designed by Yingjiang technician, it was..."
As he said this, Professor Su was shocked and said, "Is it designed by Battalion Commander Wang?"
He Zhimin nodded slightly, held the design drawing in front of Professor Su, and said, "It was probably designed by Battalion Commander Wang..."
"This is impossible!" Professor Su denied without thinking: "As a soldier, he knows how to carry a gun and fight, how can he design such a complicated thing?"
"Lao Su!" He Zhimin took out a blueprint from his pocket and handed it over, saying, "Some time ago, I talked a lot with Yingjiang pilots when they were discussing making a prototype. Do you know what they said?"
Professor Su took the drawing and asked, "What did you say?"
"This Battalion Commander Wang is not simple!" He Zhimin said: "He has developed a lot of equipment, such as 50 small artillery, rocket launchers, and rocket launchers. He also invented this rocket launcher that is hung on an airplane and fired. I drew it when I saw it.
Come down, can you see anything?"
Professor Su looked at it, then took a breath and said: "Bring the gun into the air, and there is no recoil. Although it has no accuracy, it can be covered by quantity. Coupled with the speed of the aircraft..."
He Zhimin nodded: "It's so natural! I can't believe this thing was like this as soon as it was invented. It should at least go through a period of testing and modification before being put into actual combat. But Battalion Commander Wang just does it
Here it is, it was used in actual combat as soon as it was invented, and it is the only example of this in the world! This is so similar to the 'high-precision rocket' we are developing... We seem to be developing it, but in fact we are just following Battalion Commander Wang's drawings
Just do as ordered!"
As he said that, He Zhimin came close to Professor Su and whispered: "Old Su, Battalion Commander Wang is the master! He keeps his secrets secret, and we can't be deceived by his appearance!"
Professor Su couldn't help but fell silent after hearing this, and thought to himself: Is this kid capable of this?
