What is the concept that a 1.8-displacement air-oil-cooled engine can reach a maximum power of 280 horsepower and can operate stably with an output of 210 horsepower? Major General Wu is really unimaginable, he only knows that the maximum power of the air-cooled star-shaped five-cylinder engine used by the Air Force is only 270 horsepower, what kind of double-supercharged engine designed by Lin Hongfei, relying on a set of air-cooled radiators to refuel the cooling auxiliary cooling system, how can it reach a maximum power of 280 horsepower? This makes Major General Wu feel a little incredible, a bit sci-fi, this is just an oil-cooled engine.

If Lin Hongfei told him that this was just to ensure the stability of the engine and the power could be reduced, otherwise the maximum power could easily be up to 300 horsepower, I don't know how he would feel.

Since Major General Wu can serve as the first deputy minister of the Air Force Equipment Department, he naturally knows a little bit of skills, and he must have two brushes in his hands, he knows very well what it means for a paratrooper assault vehicle that needs high-speed assault if it can really burst out with such a large amount of power and torque, but it is still the same sentence, this is an oil-cooled engine, the engine is the core of a high-speed assault vehicle, it is the top priority, and it must be clarified, "Mr. Lin, the maximum power of this engine is really so big?" How do you do that? How to ensure that the engine will run for a long time without thermal attenuation of power and cylinder burst? How many times is the area of an air-cooled heat sink compared to the surface area of a cylinder? ”

Hey? Lin Hongfei couldn't help but be surprised when he heard it.

These problems are all problems faced by air-cooled engines for a long time, and people who don't really understand internal combustion engines won't understand these at all, he gave a thumbs up, "Major General Wu, you are really proficient in technology." Every question is asked on the key point: you don't have to worry about the power problem, this can be tested on the power testing machine, the principle is that after the use of mechanical and turbo double supercharging system, the pressure in the cylinder is much greater than the pressure of the civilian gasoline engine, and the gasoline burns more violently, which can naturally burst out with greater power. ”

"Of course, more power inevitably puts more pressure on the cylinder, so we use a thicker forged cylinder block, as well as pistons and connecting rods to ensure the strength of these key components, while a special protective layer is plated on the inner wall of the cylinder. Ensure that the friction coefficient of the cylinder wall can be smaller, reducing power loss; In order to ensure the heat dissipation efficiency of the engine as much as possible, we have adopted a 75 times ratio design, and the heat sink is thickened and enlarged to ensure that the heat is dissipated in time. To ensure the normal operation of the engine, as for more detailed technical details......"

Speaking of which. Lin Hongfei paused slightly.

Wu Zhenguo immediately understood. The detailed technical details are not intended to be revealed, at least not at this time, although I feel a little uncomfortable, but I can also understand that now Lingyun Machinery Factory and BAIC are competing for this project, and Guqi Industrial Manufacturing Co., Ltd. needs to introduce its advantages clearly. As for the technical details, when it was determined that the Guqi Provincial Industrial Manufacturing Co., Ltd. would be the main one, they would have to explain it clearly.

If you don't understand, you can't do it, now the senior leaders of the Air Force know that Sister Rong is particularly concerned about this Guqi Provincial Industrial Manufacturing Co., Ltd.

He immediately stopped asking the question. turned to another question, "Okay, Mr. Lin just said that in addition to the improvement of the engine, there is also the improvement of the power delta wing?" Can you tell us about this? ”

"Of course there is no problem," Lin Hongfei smiled, "In fact, when we are improving the high-speed assault vehicle, we are trying to make such a design, or improvement: how to make the power delta wing and the high-speed assault vehicle into two separate and rapidly integrated air-ground integrated combat systems?" ”

Lin Hongfei's words were a little awkward, even Wu Zhenguo thought about it for a while before he understood the meaning of his words.

"Under the premise of ensuring that the high-speed assault vehicle is fully armed and combat performance, our preliminary idea is to achieve the following functions by adding three modules, the first is to cancel the power system of the power delta wing, directly use the power of the high-speed assault vehicle itself to replace the power of the power delta wing, and integrate the control system of the power delta wing into the co-pilot position of the high-speed assault vehicle, which is why we want to make the engine power of the high-speed assault vehicle so large. This saves at least one engine, fuel system and the weight of the driver, and the weight of at least 220 kilograms is reduced, which is huge for a power delta wing to fly into the sky; ”

"Second, the delta wing should be able to quickly combine and separate from the hull, and when it is time to throw it away, it is completely possible to abandon the delta wing in a matter of seconds and rely on parachutes to parachute in turn;"

"The third point is an air drive module, after takeoff, to ensure that all the power of the engine is used to drive the propellers, not the wheels, and if necessary, this air drive module can be thrown away in a very short time, and there is an automatic separation device to separate the system from the high-speed assault vehicle, and also to separate the delta wing from the high-speed assault vehicle."

Major General Wu frowned and thought for a moment, he carefully imagined all that Lin Hongfei said: first, there must be a high-power high-speed assault vehicle, and then there must be a delta wing that can be installed and separated at any time, and a set of transmission systems to transmit power to the propellers of modular design......

Fuck me! Isn't this just a high-speed assault vehicle that can fly autonomously?!

Lin Hongfei's design is not just crazy! That's just madness!

If this idea can really be realized, then if it is a combat within a radius of several hundred kilometers, what do you need to do by transport aircraft by air, just fly over! Although the flight speed of the power delta wing is a little slower, it cannot stand the short preparation time, the take-off speed is fast, and it can be put into combat immediately after landing, which is much faster and more effective than the traditional rapid landing operation.

"Yes, that's why I designed this high-speed assault vehicle, so that when something happens in Gyeonggi, it can support Gyeonggi in the shortest possible time." Lin Hongfei nodded and gave Major General Wu an affirmative reply, "This is also a requirement for the 127th Division to establish a new type of rapid reaction force." ”

"What is the combat radius you designed?" Wu Zhenguo's eyes lit up! "How long does it take for the entire plug-in module system to be installed in place? The power system is transmitted to the propeller, your design ideas? ”

"According to the requirements of the 127th Division, the maximum combat radius should be able to reach 1000 km," paused. Lin Hongfei explained, "However, the concept of this combat radius and the combat radius of the Air Force may be slightly different, the combat radius of the 127th Division refers to the maximum flight distance of 1000 kilometers, and it can enter the combat state immediately after landing on the ground, without considering the problem of returning home like an airplane, because the engine uses ordinary civilian gasoline, so there is no need to consider the establishment of a special fuel supply system, and it can be refueled at the nearest civilian gas station." ”

"For the installation and release of the delta wing and propeller drive system, the installation time is required to be no more than 10 minutes, as for the disengagement. Whether an automatic disengagement system or an explosive bolt is now being considered; ”

"For the transmission of power, my idea is to design a transfer case, the principle is similar to the transfer case on the off-road vehicle, but different from the transfer case of the off-road vehicle, the power distribution of this transfer case is two-wheel drive, high-speed four-wheel drive, low-speed four-wheel drive and zero-drive. On zero-drive, the power is all distributed to the propeller. ”

A combat radius of 1000 km?

As a leader of the Air Force. He quickly figured it out in his mind. According to Lin Hongfei, within a radius of 1,000 kilometers, the combat effectiveness of the airborne troops will not be limited by the transport capacity and number of transport planes, and the most reasonable distribution can be made according to the needs of the situation...... He specially learned about the power delta wing designed by the Guqi Provincial Industrial Manufacturing Co., Ltd., which is very low-cost and can be equipped in large quantities by the Air Force. As long as Lin Hongfei can really do what they say.

It is even possible to use the transit airport to achieve the second wave of support operations: the first wave is quickly transported by large transport planes to the combat area, and these high-speed assault vehicles using separable power delta wings pass through the transit airport, which can fully achieve the goal of achieving a combat radius of 2,000 kilometers within 12 hours, and there is still a little rest time at the transit airport in between.

If this mode of operation can really be realized...... Oh my God. This is simply a subversion of the concept of special operations, and if it can really be realized, it can even bring about a new revolution in the concept of special operations! This is simply an upgraded version of the US military's "leapfrogging" tactics: the combat radius of US helicopters is not 1,000 km, and it is far from being able to reach a combat radius of 2,000 km.

Thinking of this, Major General Wu even trembled slightly with excitement!

From the perspective of an old air force, how could he not see that Lin Hongfei's idea was actually not very difficult to realize in terms of technique? There may be difficulties, but they are definitely problems that can be solved, and only Lin Hongfei's unique solution is the most valuable.

Major General Wu, who was still cooperating with BAIC or with Guqi Provincial Industrial Manufacturing Co., Ltd., who hesitated a little, immediately made a decision, and after going back, he had to persuade the leaders to agree to cooperate with Guqi Provincial Industrial Manufacturing Co., Ltd., compared with BAIC, Guqi Provincial Industrial Manufacturing Co., Ltd. not only has technical strength and strength, but also has Lin Hongfei, an expert in internal combustion engine design, and more importantly, his advanced way of thinking is irreplaceable by others.

"That's right," Lin Hongfei smiled honestly, "but after all, the gasoline engine needs electronic ignition, considering that the future battlefield conditions are more complex, and all kinds of electromagnetic interference are becoming more and more serious, I am considering developing a new generation of special diesel engines, diesel engines do not need electronic ignition, and work in a purely mechanical way, which can ensure that high-speed assault vehicles can also perform combat missions according to requirements in the battlefield environment with strong electromagnetic interference." ”

When everyone's attention is still on improving the power of the gasoline engine, this kid has already begun to consider a special diesel engine? The shock in Wu Zhenguo's heart is simply incomprehensible, at this moment, there is only one thought in his heart: to cooperate with Guqi Provincial Industrial Manufacturing Co., Ltd.! It is necessary to cooperate with Guqi Provincial Industrial Manufacturing Co., Ltd.!

At this moment, he was purely from the perspective of improving the combat effectiveness of the Air Force, and he had nothing to do with Sister Rong.
