Needless to say, just take power as an example, Yuejin Off-road Vehicle uses an NJ70H engine that imitates the GAZ51 and an inline 6-cylinder single-cavity carburetor structure. The maximum engine power is 87 horsepower.
That's right, it's such an engine with gasoline power and power is not enough for even one hundred horsepower, so its performance is quite poor. Then, with a four-speed transmission, the fuel consumption of 100 kilometers is as high as more than 20 liters.
Such a power system is only enough and definitely not excellent. Therefore, the off-road performance is also quite poor, and it cannot be compared with our own.
With an engine with a capacity of more than 300 horsepower and a nine-speed transmission, you can reach 100 on the road and 60 in the wild. If you are not afraid of being confused, you can reach 80.
What do the troops don’t like about such an off-road vehicle?
This time I asked Professor Wang and Professor Cao and others to come here, but it was actually for this matter to expand the product line of their own wheeled infantry fighting vehicles!
Since it has matured on both the Yuejin Car and the 212 Car, it is perfect to place it on your own wheeled infantry fighting vehicle. Therefore, once it is assembled, it will naturally be perfect to participate in the military parade.
That's modernization!
However, when the car drove to the side, Wang Liming smiled bitterly there and said to Qin Zhenhua: "Zhenhua, your idea is good, but this car is a bit big!"
What?
When he heard Wang Liming's words, even Qin Zhenhua was speechless. People thought it was small and wanted to make a bigger one. How could you think it was big?
"Our army has no money." Wang Liming said: "You think we already have a portable launch device, even if it is a 212, with a set of portable devices, we can participate in the battle. What about you? Such a guy
Isn’t that a waste to use as a special anti-tank missile launcher? The troops are in short supply and cannot withstand such tossing.”
This sentence aroused Qin Zhenhua's deep thoughts, and soon he reacted.
What they said is right!
This car is a bit big!
If you want to sell the equipment, you must have an accurate market positioning. If this kind of car is used as a wheeled infantry fighting vehicle and stuffed into an infantry squad, it is actually a bit small, and it must be enlarged to the eight-wheel structure to be suitable.
However, if it is just used as an anti-tank missile launcher, it will appear to be huge and cause waste to the troops. After all, the troops' equipment costs money, and now the military expenditure is tight!
"From the Soviet Union's perspective, the Soviet anti-tank missile launchers were almost all four-wheeled vehicles." Professor Wang Liming continued.
In the 1973 war, the Soviet BRDM-2 anti-tank missile launcher made its first appearance. It was a two-axle armored vehicle. It was modified based on the same model of armored reconnaissance vehicles and could also be used to replace the early days.
BRDM-1 models equipped with Snapo, fly swatter or Seg anti-tank missiles.
If our Red Arrow-8 anti-tank missile also needs a special launch vehicle, this type of vehicle is the most suitable.
After all, Professor Wang Limin has been studying this area for the longest time, and he can tell what is the most suitable at a glance. Now, when he heard Qin Zhenhua say this, he immediately brought it up.
"Yeah, I understand." Qin Zhenhua said: "But this is not a big deal. Second pillar, second pillar, second pillar, come down!"
The one who drove this car was Wang Erzhu. He was still busy in the car at this time. As a result, he heard Qin Zhenhua's shouting, so he jumped out of the car.
A different look flashed in Cao Jianli's eyes, and then returned to normal again. Every time she saw Wang Erzhu, there would always be a turbulence in her heart.
Now, Wang Erzhu has grown up and has become an important figure in the first machine factory.
"Brother Zhenhua, what's the matter? Professor Wang, Professor Cao, hello." Wang Erzhu shouted.
"After returning this car, it becomes a two-axle structure, shortening the length by two meters!" Qin Zhenhua said: "The engine is also reduced by one level. In three months, take out the new vehicle for us!"
There is still a lot to say? This car was completely developed by ourselves. It is easier to reduce the shaft than increase the number of shafts.
If you increase from three-axis to four-axis, you need an additional steering shaft. The front two rows are steering wheels. In this way, higher requirements are put forward for the steering machine and complex training is also required.
However, there is no such thing as reducing the shaft. It is fine to remove the shaft at the end directly, or even perform surgery directly on the car in front of you.
Of course, the current one-machine factory is not short of money. After modifying the design drawings, they can produce one specifically.
"Yes, but, what's the use of this car? Will the mobility decrease?"
"Mobility cannot be reduced, but its use is great, and the entire series of vehicles will be even richer." Qin Zhenhua said.
In theory, the off-road capability of three-axis vehicles is definitely stronger, but the two axes will not be particularly bad, because the number of axes is small and the car is shorter. Anyone who plays off-road can know that the off-road capability of the short-axis Suzuki may not be longer than the off-road capability.
The Prado of the axis is worse, and even passability is higher.
This car is not only used as a missile launcher, but also can be used as an armored reconnaissance vehicle, completely replacing the status of 212 in the tank troops!
Before the tank troops operated, there were scouts in front of it. During World War II, it was used as motorcyclists. Later, technology developed and specialized half-tracked vehicles were available. Now, naturally,
It is a wheeled infantry fighting vehicle with faster running speed. It doesn’t have to be too big, it’s too big and conspicuous. Anyway, it doesn’t need to be equipped with an infantry squad, and two or three people are enough!
"Okay, three months, make it out, it's perfect." Wang Erzhu said, patting his chest.
"Well, when this car is being developed, communicate more with Professor Wang to see what they need, and we will consider what we design." Qin Zhenhua said.
"yes."
"What do we need?" Wang Liming thought for a while and said, "This hand-cranking method is really inconvenient. The precision processing capability of the first machine factory is good. If it turns into a hydraulic or air pressure method, it would be even better.
”
"Of course there is no problem with this. If the entire equipment is integrated, at least four pieces must be raised at one time." Qin Zhenhua said: "Where should we get on the car? Let's feel it while talking?"
Several people got into the car with a smile, sat on the seat behind, and told Wang Erzhu to click slowly. With the sound of the high-pressure oil pump, the car continued to move forward.
