Soviet aircraft designers, like pilots, seemed to be fond of large-caliber guns, and the Yaks in front of them were clearly the product of this kind of thinking - they did not have a high range, because they did not need to be used in the design indicators for long periods of repeated dogfights and cruise-looking fighters, standard front-line fighters. Pen "Fun" Pavilion www.biquge.info

Some time ago, some front-line air battles exposed a problem, and it is also a problem that often occurs -- many fighters participate in the battle as soon as they take to the air, but often the air battle is over before the ammunition is finished, which makes the front-line troops hope to get equipment to kill the enemy in one shot!

Lin Jun understood the shortcomings of the Soviet-style artillery arrangement, and the air war to resist US aggression and aid Korea reflected the respective advantages and disadvantages of the Soviet-style and American-style thinking -- on the one hand, the ammunition was often exhausted after a few rounds of shooting, and the duration of the firepower was too short, but once it hit the opponent, the opponent was almost dead; The 6 large-caliber machine guns on one side have excellent firepower, but sometimes they don't hit the vital point, and the opponent sometimes returns to the airport with dozens or even hundreds of bullet holes!

The huge 37mm cannon on the Yak in front of him must have been a nightmare for the opponent, and the German fighter would be "dead or maimed" as soon as it was hit by a single shot, not to mention the two 20mm guns on the wings.

The barrel length of the 37-mm НС-37 gun is 2300 mm, the weight of the paddle hub gun is 171 kg, the rate of fire is 240-260 rounds / min, and the power is terrifying!

The shells of the НС-37 aircraft gun include tracer armor-piercing incendiary and tracer anti-personnel incendiary shells. The tracer anti-incendiary projectile weighs 732 grams, is loaded with 34 grams of A-IX-2 explosives, and has a muzzle velocity of 865 m / s: when the tracer anti-incendiary projectile hits a duralumin skin 1-1.5 mm thick, a large hole with an entrance diameter of 0.46 m and an exit of 0.78 m is formed!

The tracer armor-piercing incendiary projectile weighs 770 grams and has an initial velocity of 810 m / s. Tracer armor-piercing incendiary shells can penetrate 50 mm thick armor at a distance of 200 meters, and 30 mm thick armor at an angle of 45 degrees; It can penetrate 45 mm of armor at a distance of 400 meters, and 40 mm of armor at a 30-degree angle.

As long as one shot is hit, the fighter is basically reimbursed, and if it is a bomber like the Junkers 88, two or three rounds are basically finished.

Lin Junning can use it to deal with bombers, and the Soviet-style cannon thinking will also be suitable for confrontation thinking with the huge four-engine bomber formation in the Western world in the future, and there is nothing wrong with it -- if the American-style "standard 12.7mm machine gun" configuration is used to deal with the B29, B17, and B24 groups, the effect will definitely not be much better, let alone the huge B52!

This will be a little strange for Lin Jun, because it is too quiet here: the two checkpoints outside are well guarded, but although this newly built airstrip is not big, it still has a complete hangar, repair shop, and barracks, but Lin Jun will only see two sentries on the edge of the apron, and one more on the improvised tower.

Probably, there will still be people in the hangars and barracks, but such a day, although it is a little cold, but it is only a sunny day, which is by no means in line with the normal phenomenon of any military airfield.

"Sentinel!" Lin Jun shouted at the sentry who was patrolling in the distance.

The sentry on duty immediately ran over quickly, and stood two meters away from Lin Jun and saluted.

"What's going on, what about the others?"

The young sentry immediately understood why the marshal asked, "Report to Comrade Marshal, the technicians and most of the guards here went to the first airfield according to the orders of the Academy. It's the original airport, and this is Airport No. 2. The specific reason for this has not been explained to those we have left. ”

"Well, let's go back."

"Presumably Arkhipov has some new classified equipment there, let's go, go and see." Lin Jun turned around and said to his wife, "Why don't you go home first, I'll go over there and have a look first." ”

"Yes." Vukinskaya got into car number three, and the driver took her back to the villa first.

The other two cars drove to Airfield No. 2, three kilometers away, and as they approached the airport, they saw sentries patrolling the woods, apparently also heavily guarded (as you may see, the Zhukov Academy covers a huge area: it is very large, otherwise it would not be possible to accommodate two airports). It's like some of our universities have a huge footprint -- it is said that some universities are so big that they have to run buses in the school. ）。

As soon as you pass through the woods, you will be greeted by the huge Airport 1, which is now covered with snow for aircraft to take off and land, as well as a 2,200-metre-long and 35-metre-wide reinforced concrete main runway and a 1,200-metre-long taxiway connected to it, which is also known as Runway 2.

In terms of airport hardware alone, the newly renovated airport of Zhukov Academy before the war has first-class facilities, and if you look at the large airports of various countries around the world, its conditions are also first-class!

Lin Jun saw that many people and vehicles had gathered outside the hangar on the other side of the runway, and the soldiers on armed patrol were scattered all over the airport.

When the car approached, Lin Jun saw a monster!

"Oh my God!"

Lin Jun screamed unconsciously, because the object he saw surrounded by the crowd was a "miniature version of the B-2 stealth bomber"!

As soon as I got out of the car, I didn't look at anyone, and walked quickly to the tailless aircraft - its wingspan was about 16 to 18 meters, its length was about 8 meters, and its height was less than three meters, like a super bat with its wings spread!

A flying wing, an apparently jet-powered flying wing, and a cross-era jet stealth aircraft appeared at the Zhukov Academy in Moscow, the Soviet Union at the end of 41 years, and Lin Jun even thought about whether there was an aircraft designer who "crossed" like himself decades later, or "airplane crossed"!

Seeing that the chief had no intention of greeting the others, the attachés quickly followed, squeezing everyone else in at once.

knocked on the wings, looked down at the landing gear again, saw a ladder in the nose position, and climbed the gangway in two steps: "Come out!" Said to a man dressed as a mechanic in the single cockpit.

The captain was taken aback by Lin Jun, because he was looking down to check, when he suddenly heard a sentence in an extremely stern tone, and when he looked up, he saw that it was the deputy commander.

Hurriedly climbed out of the cockpit and took a corner of the ladder to the ground.

Lin Jun poked his head into the cockpit and looked east and west, and suddenly Landscoche behind him seemed to hear him talking to himself: "Which genius made it?" That's it! ”

Lin Jun has already determined that this is not a "crossing plane", because the wings are wooden structures and should be made of plywood, and the landing gear and the internal instruments and control facilities in the cabin are all current technology. However, the person who came up with this shape must have been a genius - Lin Jun knew that the German brothers Rema Horton and ****** Horton had designed and built the tailless flying wing Ho-229 fighter-bomber (also known as the Go-229) in World War II, but he had never heard that the Soviet Union also had tailless flying wings.

The instruments in the cabin are all marked in Russian, which also means that you Nazis developed the Ho-229 fighter-bomber in advance and were captured by your own side, so what is going on?

Lin Jun was obviously shocked by this flying wing that was ahead of his time, and then he thought of asking the people in the airport - which genius designed this plane? Which manufacturer made it? Why didn't the Air Force report to itself?

"Marshal."

Before Lin Jun could turn around from the ladder, he heard an acquaintance greeting him behind him.

Turning his head: "Polikarpov, Arkhipov, what's going on?" ”

Lin Jun asked with a few steps: "Who designed it?" How did I not know? ”

The eldest brother Arkhipov pointed to the veteran designer next to him, "He." ”

The "King of Soviet Fighter Design" designed the flying wing, which is a bit unbelievable!

"Isn't he designing jet fighters?" Lin Jun had been keeping an eye on the design of the jet fighter, but the Soviet's first jet fighter didn't seem to be so easy to come into being - a prototype test machine with a piston engine (mainly used to test aerodynamic performance, and the engine was mounted in the nose of the nose that reserved room for the cannon). Test flights have already been carried out, but approximate modifications are needed, and even a prototype with a jet engine installed has not yet come out.

The shape of the jet fighter designed by Polikarpov has been modified to be the same as that of the Messesmitt 262, which is clear to Lin Jun from the reports he keeps sending, otherwise he would suspect that the one next to him is a "jet fighter"?!

The advent of jet fighters is not urgent, and the new subject is not even to have an engine, not to mention that the DP-1 turbojet engine is still being modified to increase reliability.

Seeing that the deputy commander-in-chief was anxious to understand the situation, Polykarpov hurriedly explained: "This aircraft did not affect the development process of the new power fighter, and my design team made it from surplus materials. ”

"Whose idea?"

"That's me, but the internal structure was designed by a couple of young people who had just graduated from the design school and transferred to me. Half a year ago, I saw in Gorky that a middle school student whose father worked at the airport was playing with a flying wing in the family's living quarters, and threw it down from the third floor and glided smoothly for a long time. It was thought that if the fuselage and tail of the aircraft were canceled, only the main wing of the wing-body fusion would be retained, which would reduce the air resistance encountered by the aircraft in the air and increase the speed. ”

"Because of the tight task, I asked a few young people who were not in charge of the main development work to figure it out, and the boys quickly did a whole set of research using the model I asked the middle school student to borrow, and also built a full-scale unpowered flying wing from waste materials."

Comrade Designer said a long paragraph in one breath, and Lin Jun was stunned when he heard it: "It's all right?!" I'm really afraid that I can't think of it, I'm not afraid that I can't do it! ”

In order to keep the work of designing jet fighters secret, Polikarpov moved the design team to the city of Gorky, and the idea of this flying wing was actually conceived by a 7th grade student with a flexible brain, even a bit of an alternative, love of aeronautical models!

Who would have thought? A small inducement, coupled with a few young people who dare to innovate boldly, have no burden and have the support of mentors, this epoch-breaking flying wing prototype was born!

The young man who had just graduated from the design institute knocked on his own, and with the help of several sheet metal masters and carpenter masters in their spare time, they built the unpowered full-scale flying wing in a short time - this unpowered aircraft without an engine even had a built-in landing gear and a complete cabin, all of which were scrapped out of the scrapyard, and the young men did it in one step in order to shorten the time as much as possible: but the landing gear was fixed in the fuselage, and the cockpit control system could control the various aerodynamic wings.

Next, an old SB-2 bomber was used for towing tests, and a daring designer carried a parachute into the cabin, taxied on the lawn and was dragged into the air - a hand-built flying wing that was simulated and verified by only 7 models of various sizes, and assembled entirely from scrap raw materials, turned out to have flight quality that fully met the flight requirements!

What happened next was even more magical! This caused a small sensation in Polikarpov's design team, and as a result, the young people were not only not scolded for their adventures (the test flight was carried out without Borikarpov), but received further support.

Instead of going to the scrap heap, a few carpenters, fitters, sheet metal workers, and electrical technicians were formally assigned to their independent research team, and were allowed to use a batch of valuable raw materials to build a testing machine for power equipment.

Under the guidance of Polikarpov, the steel beam structure used for the original support was replaced with valuable high-strength aluminum alloy support tubes, and the finished 17 mm thick aviation fir pressed multi-layer plywood was used as the main skin, and a DP-1-2 jet engine was installed on each side of the center and front cockpit.

The boys did not use aluminum alloy as the main skin material, because the rationing department said that it was difficult to deploy, and because no one had the bottom and could not bear the risk of being charged with "wasting national resources", they replaced it with a sufficient amount of plywood, so that there was no need to report, and the Polykarpov design team itself had the right to allocate small quantities.

But even the materials didn't seem to be perfect, and the boys still installed the plane with a pressurized cockpit, using the technology of the Pe-2; Because the fuselage was flat, there was no place to install a large fuel tank, and as a result, the fuel tank was designed into the load-bearing structure of the entire flying wing, and the fuel load volume coefficient inadvertently created a record high!

The first test flight was the same daring young man as a pilot - the test pilots obviously did not have confidence in it, and the designers themselves knew best: the aircraft they participated in the design of the aircraft they could.

The running distance is super long, which makes people look intimidating, but the flight quality is smooth. Because it was the first test flight, I landed after two circles - the landing and gliding distance were much closer.

The next day, the test flight continued, and the pilot was inspired to fly higher and higher, and finally the highest mark of 12,000 meters reached the top of the altimeter - the pilot did not dare to climb again!

What about speed?

800 km! The designers in the cabin are simply difficult to execute! -- The throttle putter is not yet complete!

The second test flight took place the day before yesterday, and only then did this unplanned "monster" be reported, and Lin Jun didn't know about it.

Why come to Zhukov? Because if you want to continue experimenting, you can't do it in Zhukov, there are things that the Gorky research base does not have.

(Do you still have a commuter pass?) Hehe. (To be continued.) )
