In fact, the U.S. military, before the Gulf War, underestimated the extreme conditions faced by gas turbines in a desert environment.

Due to the harsh use environment, the M1A1 tank fights in a desert environment, and the tank crew members must maintain the secondary filter for a long time every day, which greatly reduces the battlefield breakthrough ability of the M1A1 tank, but fortunately, the Iraqi armored force has been blown up by the coalition air force, and the M1A1 tank has not encountered any strong battlefield threat.

After the Gulf War, the M1A2, the first major facelift of the M1A1 tank, directly increased the original 6.15 cubic meters of power compartment to 7.6 cubic meters, and the extra space was occupied by the improved two-stage air filter.

In addition to a large number of electronic equipment, the facelifted M1A2 tank has also undergone important improvements in terms of maintainability, and after the improvement of the secondary filter, even in harsh desert environments, the M1A2 tank only needs to have a secondary filter serviced once every three days.

The M1A2 tank is a bit of a, almost everyone knows it on the network in later generations, Liang Yuan naturally will not fall into the big pit of T80 and M1A1, and at the beginning of the project, he directly rejected the thrifty and space-saving single-stage boxless filter scheme, but the local tyrant chose the M1A2 scheme.

In fact, judging from the current operational needs of the Republic Army, whether it is the Korean Peninsula, the other side of the strait, or the roof of the world, it will not encounter a perverted dusty environment similar to the desert, and it can directly stuff the jewel power pack into the 59 car body, which is a single-stage boxless filter with a simple version of a two-stage filter with a size of half a cubic meter, which is enough to meet the combat conditions.

The problem is that 1,000 institutes have entered the field of military industry, in the name of the project of Pakistan's next-generation main battle tank, the environment of Pakistan is not stronger than that of the Middle East, don't look at the desert that is not big but can be called, there are six or seven, and the Balochistan wasteland near the border with India and Pakistan is as dusty as the Middle East desert ruled by the subtropical high pressure in summer, and the ground temperature is even close to 50 degrees, which is the hell of all main battle tanks.

In the near future, when Pakistan purchased main battle tanks, all the world's well-known tank series were planted in the Balochistan wasteland, Britain, France, Germany, the United States, Russia, plus Pakistan's old friend republic, none of the country's main battle tanks could pass the field test of the Pakistan Army, and the German MTU company even directly refused to improve the diesel engine of its own Leopard tank for the Pakistan Army's tropical desert needs.

Since Liang Yuan intends to make a difference in Pakistan's next-generation main battle tank, he will naturally apply the field experience gained by the American M1A2 tank in the Gulf War in advance.

Of course, the gem engine is a AGT1500 with less air intake than the M1 series tank, and there is no intercooling and reheating system that occupies space, and the final size of the tank power pack is controlled at about 5.2 cubic meters, and the power compartment of the 59 tank is only 3.5 cubic meters.

Yuli Victor did not understand the ins and outs of the tank project on the gas turbine, and naturally he was accustomed to the republic's choice of the American technical route, and then sprayed the republic's tank designers in front of Putin.

However, the Soviet delegation was also impressed by the 1,200-horsepower engine of the 59 experimental prototype, which was unbelievably fast in terms of acceleration performance alone, and the acceleration of the tank at the start even led to a slight increase in the turret.

The original matching tank engine of the Type 59 tank was only 520 horsepower, and after the replacement of the jewel power pack, the performance was doubled and turned, so that the experimental prototype car climbed over various slope obstacles and drifted in time and space The scene can be seen everywhere, and even gives people the illusion that the 59 tank can fly with wings.

In addition, due to factors such as complex transmissions or power conversion, the experimental bodies of several types of diesel-fuel alternation and diesel-fuel combined drive are far less refreshing and neat than the simple gas turbine drive from the perspective of the tank obstacle crossing scene.

This made it even more difficult for Liang Yuan, who was accompanying the Soviet delegation to watch the tank test, to make a decision on the choice of the form of drive.

Although the Republic did not come up with the T80 tank as a treasure like Lao Maozi in this bilateral exchange between China and the Soviet Union, it is also full of sincerity to come up with the world's third test prototype of the main battle tank powered by a gas turbine.

After all, the armor and firepower of the tank are all based on the power system, as long as the data of the power system is known, as a Soviet engineer with rich experience in tank design, he can naturally deduce the approximate data of the next generation of main battle tanks of the republic.

There are six tanks in the Tieling test base at the moment, and this time the Soviet delegation arrived, and the base directly used three tanks for demonstration, even if there was no firepower to hit this project, a tank off-road test was completed one after another at noon.

The canteen of the Tieling base is naturally incomparable with Shangri-La, the canteen of the base has prepared a lot of steamed rice tortillas and several large pots of pig-killing dishes, and the Maozi delegation has tasted an authentic Northeast folk flavor.

After lunch, a short exchange and farewell meeting was held in the conference room of the base, and the journey of the Soviet delegation to China was regarded as the end.

At 1:30 p.m., the Soviet delegation left the tank base by car and went directly to Taoxian Airport to take a flight from United Airlines back to Beijing, and then transferred to the Il-86 wide-body passenger plane of the Soviet National Airlines to return to Moscow.

However, not all of the members of the delegation returned to China, and according to the results of this exchange, the Chinese and Soviet militaries will continue to push forward the negotiations between the two sides on the purchase of advanced Soviet fighter jets in Shengjing.

The negotiations took place at the Shangri-La Hotel in Shengjing.

What Liang Yuan did not expect was that Putin actually returned on time after contacting Liang Haiping once, and Ms. Nina, who was eyeing Comrade Vladimir, stayed in the Soviet negotiation preparation team in Shengjing as a Chinese interpreter.

The Soviet delegation left, followed Liang Yuan to the tank base to see the lively twins, and returned to Shengjing with the convoy because he was going to the airport to send Ning Lei, but Liang Yuan did not follow the Soviet delegation to meet Shengjing, but stayed in the testing center of Brilliance in the tank base to participate in a routine meeting.

Of course, the participants in the meeting were a bit special, in addition to Zhao Tianshi, the technical representative of Brilliance stationed at the tank base, and the third-generation main battle tank project team of the Republic of China's military, there were also two special personnel, Colonel Rahman Shah, an officer of the Pakistani Army, and Colonel Tariq Morio, an officer of the logistics department of the Pakistani armed forces.
