The thirty-eighth round of the first flight of the jet

[38] The first flight jet

Nanyuan Airport in 1949 was surrounded by military siege and martial law on all sides.

In order to ensure an adequate supply of fuel, the central authorities purchased a large amount of aviation fuel from the Soviet Union, using the money from the $300 million loan that the Soviet Union had provided to China.

The aviation brigade has seen the Jian-5 on the ground from the inside to the outside these days, and the mechanic team has even memorized the names of each component according to the drawings, although they have not understood the functions of a few parts for the time being. But this fiery drive is unimaginable, and from a modern point of view, it is simply insane.

The pilots have memorized the functions of every instrument these days, and the pilot's manual, which has been revised by the 491 Project Headquarters, has also been memorized day and night.

Everyone who participated in the test flight of a jet fighter was a great honor, a jet, a jet! Even their Japanese instructors had never touched such aircraft. Every instrument on this silver warhawk is mesmerizing, and all the manuals and in-flight markings and even the scales are in Chinese.

According to the superiors, the origin of these planes is a state secret and no inquiries are allowed. But most people believe that this must be imported from the Soviet Union, and a small number of people think that this is China's procurement of parts and self-assembly, otherwise how can even the manual and dashboard be marked in Chinese?

These days, the pilots don't mention how high the motivation is, saying that the motivation is not blowing, everyone simulates the process of flying in their minds over and over again, after all, no one has ever flown a jet fighter, everyone is nervous, who wants to say that they are not nervous is bragging, just imagine, everyone is a starting line, you can't fly well, people fly well, how shameful it is, these selected pilots used to be the combat elite of the army, the body is good, the brain is working, the competition is used to it, where can afford to lose this person!

After discussions, the flight group decided that Wang Hai, the outstanding captain of the flying group, would fly the Jian-5 for the first time today, and if successful, it would be the first pilot in New China to successfully take off and land a jet plane.

Previously, the head of the Air Force repeatedly instructed that if there was an accident, use the ejection seat to escape, and the plane and the pilot should resolutely protect the pilot! No ambiguity!

Wang Hai checked the instruments in the cabin, all the instrument data showed that the plane was normal, he helped the ground crew to pull up the hatch cover, started the engine cautiously, the plane moved, and slowly taxied towards the runway.

Wang Hai looked ahead calmly, calmness is his specialty. On this shijie, only those who can take calmness as a specialty are qualified to become pilots.

J-5 accelerated and sliding, Wang Hai looked down at the instrument data from time to time, the speed of the plane is getting faster and faster, and it has reached a take-off speed of 235 kilometers per hour on the runway, the time has come, Wang Hai gently pulled up the nose of the plane, and J-5 immediately roared like a silver war eagle and left the ground with firelight.

Everyone at the airport was thrilled that this historic moment was born. Today, the Chinese are finally able to take off in jet planes! Honorable! Davarisi!

In the middle of the one-hour flight, Wang Hai became more and more excited, and every time he completed a test flight action, he excitedly told the tower on the walkie-talkie, "The performance of this Jian-5 is really excellent!" It's just amazing! ”

No wonder Wang Hai is so excited, this Jian-5 even has a cruising speed of 800 kilometers per hour!

To say that Wang Hai has flown the most haode plane before, it is only the American P-51 Mustang fighter, the supercharged engine is at full power, the throttle is added to the end with 109 percent of the power to fly, the maximum speed is less than 700, I heard that the P-51 improved P-51D has increased the speed to 784 after reducing the weight by 700 kilograms. However, the J-5 uses the maximum speed of the P51 as its own cruising speed, and the maximum speed of the J-5 reaches 1145 kilometers per hour. It's like comparing Santana to Ferrari for speed.

The most terrifying thing is actually the acceleration ability of the J-5 as a jet aircraft, the acceleration curve of the propeller aircraft belongs to the kind that rises gently, and the closer to the maximum speed, the slower the acceleration, just like if you drive a farm car and want to find the legendary push back feeling, this is simply impossible.

The speed of the P51 Mustang during vertical climb in Xiangshang is 600 meters per minute, which is 10 meters per second. As a jet fighter, the J-5 has reached a terrifying 4,500 meters per minute! That's 75 meters per second. The era of fighter fighting with machine guns is like a duel between two martial arts masters, and the side that tosses and moves quickly naturally has the upper hand. The J-5 can easily use his high-speed climb to complete a lot of air combat maneuvers to the extreme.

Just like the Japanese Zero fighter in World War II, just relying on the advantage of fast climbing speed, often lured the US fighter to chase the rear to attack, and then Xiangshang pulled up and easily turned a somersault around the heavy US fighter to shoot behind the heavy US fighter. In the early days of the war, this trick was tried and tested, so that later the US military did not dare to pursue the Zero fighter at high speed.

In fact, the advantageous position of air combat in this era is to chase the tail attack, just as the navy always tried every possible way to seize the T-shaped position in the era of artillery. The vast majority of air battles are about tail wrapping and anti-tailing, and the more the performance of the opponent's aircraft is different from you, the easier it will be for you to go around the back and beat the opponent into an aerial torch.

The climb speed of the Zero fighter is only 800 meters per minute, which is only 200 meters per minute faster than the P-51, so what will happen to the J-5 pair of propeller fighters with a climb speed of 4500 meters per minute?

In April 1941, Major General H.H. Arnold of the US Army Air Corps decided to visit Britain, where the British showed him the most secret Gloucester E-28/39 jets of the time. General Arnold of the United States was extremely impressed by this, writing in his diary that "(this new jishu) can throw all existing aircraft (propeller) into the garbage heap".

At this moment, among the more than 400 fighters in Duwan Bay, 383 are the kind of fighters that are said to be thrown into the garbage heap, the models are P51-C and P51-D, and in terms of engines, the C and D are the same aircraft.

The so-called C-type P51 Mustang fighter is nothing more than the replacement of the original Allison V-171012 cylinder V-engine of the Mustang fighter and replaced it with the Merlin 68 two-speed two-speed supercharged secondary cooling engine produced by Packard. The advantage is that it has about 5 percent more power and less engine weight than the prototype, which allows the P51 Mustang to carry a 200 kg bomb (two of which are said to be able to barely take off later) as a light forward tactical bomber, which is a second class for a fighter and increases the tactical range of its own existing aircraft.

For an adversary with poor air defense, such a small-scale tactical harassment bombing of several aircraft is no small trouble. This is different from the regular bombing of the Air Force's special bomber formations, this kind of tactical harassment and bombing is a sporadic and continuous attack on positions, pillboxes, fortifications, logistics transport vehicles, and supply roads, just like mosquitoes sucking blood, nailing a bag, but it will not be fatal.

The P51-D Mustang basically follows the same idea, except that the weight reduction advantage from the replacement of the engine is compensated for in the air firepower, rather than being used to increase the tactical bombing function like the C. THEREFORE, THE D-TYPE MUSTANG SIMPLY LOADED SIX 12.7MM MACHINE GUNS WITHOUT DOING ANYTHING, HOPING TO INCREASE THE BARGAINING CHIPS OF AIR COMBAT VICTORY WITH STRONGER FIREPOWER.

THE 12.7MM CANNON IS TOO LETHAL FOR THE JIAN-5, AND IT IS IMPOSSIBLE TO KILL IT WITH ONE HIT UNLESS IT HITS THE VITAL POINT. During the Korean War, a large number of MiG-15s were shot dozens of times in air battles and flew back to the base covered with bullet holes. THE TWO 23MM AND ONE 37MM CANNON EQUIPPED WITH THE J-5 WERE ORIGINALLY DESIGNED TO BE THE U.S. MILITARY'S SUPER AIR FORTRESS BOMBER B-29, AND A SMALL MOSQUITO LIKE THE P51 WILL BE TORN APART BY THESE LARGE-CALIBER SHELLS IF THEY ARE UNFORTUNATELY HIT.
