.

Zhiwen was nervously dismantling the Indian army's transceiver, and in his bag, there were electronic tubes, power transformers, capacitors, resistors, etc. used for the transmitter. Liu Zhiwen carried these things just to convert the transmitter into a transmitter at the appropriate time and transmit the battle to the news center as soon as possible. Less than 50 miles from the front line, his boss was waiting day and night. As long as he passed it over, he would be a great achievement.

Based on past experience, Liu Zhiwen turned the coils and welded the circuits by himself, and assembled a five-watt Hartley-style low-power transmitter. He used the Indian Army's electronic tube receiver to adjust the frequency and converted it into an electronic tube receiver for the Chinese channel. After repeated tests, although the transmitter looked very normal, what made Liu Zhiwen anxious was that there was no information to return at the receiving end, which made Liu Zhiwen extremely anxious.

The gunshots not far away began to grow, and the situation became more and more dangerous. Liu Zhiwen calmed down instead. Perhaps because of the altitude sickness, his transmitter wavelength was abnormal. Thinking of this, Liu Zhiwen's heart lit up and used the frequency of Xinhua Radio and Indian Radio to calibrate the required wavelengths for work.

Then, Liu Zhiwen made the first call according to the specified wavelength, call sign and contact time

"Headquarters, headquarters, I am a certain unit of the assault company. I don't occupy an artillery position of the Indian army now. I need fire support now. My headquarters is about 5 kilometers south of ***, which is the place where the battle is the most intense!"

The transmitter used by the radio modified by Liu Zhiwen is a five-watt single-tube power Hartley ground transmitter. The transmitter uses a 6f6 or 6v6 type: some metal equipment modified to register; the power required for the register is a battery; the antenna used for the transmitter uses an inverted "l" single antenna used for radios. In order to improve the working efficiency of the radio communication and contact site, a "duplex" contact method is adopted.

It can be said that if it weren't for the fact that China's products were really good, then such a simple transceiver unit would not work no matter what. However, in extremely difficult circumstances, Liu Zhiwen actually successfully sent the telegram, and almost immediately, the receiver received the signal. However, the sound was not Liu Zhiwen's boss, but a slightly stiff voice of a woman.

"Please repeat. I am the Telecommunications Department of the Headquarters Confidential Office. I have answered your telegram. Please tell me your request immediately and I will transfer it to my headquarters immediately!"

"I am Liu Zhiwen. We now have three people who have occupied an artillery position of the Indian army. Now the Indian army has surrounded us and urgently needs fire support. If it really doesn't work, fire at us. There are as many Indian soldiers here like ants. You can reimburse dozens of them with one shot! Hurry!"

"I understand. I have already spoken directly with the commander to tell you what you are doing..."

At the critical moment, the battery finally ran out of electricity, and the sound of the transceiver decreased at the same time, and finally it was silent. Liu Zhiwen had no choice but to punch him hard. Liu Zhiwen picked up a rifle and was about to rush over. Suddenly, Liu Zhiwen saw a tractor beside him, and Liu Zhiwen suddenly had an idea.

At this time, Liu Meng and Pang Xingguo had been suppressed by the Indian army's firepower and could not raise their heads at all. They could only fight back occasionally, and the injured Pang Xingguo was furious.

"Liu Meng, I order you to retreat to the second line of defense immediately!"

"Squad leader, you're just talking about the world today, I won't go down.

"This is an order

At this moment, Pang Xingguo, hesitant, smashed the machine gun, took out the pistol and handed it to Liu Meng. He held the last grenade in his hand and waited for the Indian army to approach.

The Indian army was very close to Pang Xingguo and others. Pang Xingguo wanted to throw the grenade out, but the grenade fell to the ground. I don’t know when. His arms were already >+ machine guns. No matter how strong his flesh and blood body was, he could not withstand such destruction. His two arms were no longer in control.

Pang Xingguo endured the severe pain. He picked up the grenade with his trembling left hand, and then wanted to pull out the pull ring with his right hand, but his right hand was like a leaf in the wind. He could not use any strength at all. Pang Xingguo lowered his head, pulled out the pull ring with his teeth, and threw the grenade out. The grenade was not far away. Fortunately, the mountain was steep and the grenade rolled down the mountain. The Indian army screamed continuously along the way. One, the firepower was temporarily reduced.

"Get out of the way, get out of the way!" A harsh horn sounded behind him. Xingguo turned his head and looked at it. A broken and messy car drove slowly. Liu Zhiwen was in the car. When he drove to Pang Xingguo, Liu Zhiwen took a square thing and pressed the accelerator, fixed the steering wheel, and then jumped down.

Liu Zhiwen, who had not been trained, was obviously not a good jumper. He jumped directly on Liu Meng, and the three of them rolled into a ball. The tractor rushed out of the mountain pass with inertia and then there was a shocking explosion. When Liu Zhiwen leaned his head to look, he could only see a ball of fire rolling down, and Indian soldiers covered in fire were everywhere along the way.

However, Liu Zhiwen still saw that the Indian army below did not decrease. On the contrary, some neatly formed troops appeared at the foot of the mountain, which was obviously the reinforcements of the Indian army. Liu Zhiwen felt half-hearted when he saw this. It seemed that he was about to explain it to this day! He was not married yet, which was a big loss.

Twenty minutes later, the three people who were forced to retreat to the final position finally fired all the bullets. However, the Indian army did not launch an attack. Although they could permanently solve these three warriors by firing heavy machine guns, when they understood that there were only three Chinese who were so troublesome, respecting the heroes prevailed, and a person who looked like a lieutenant stood up.

"The Chinese warriors are now very obvious. You are surrounded and have run out of ammunition and food. Your heroic behavior is enough to be comparable to the bravest warriors, handing over the weapons in their hands. I promise you will be treated as the heroes."

"ball!"

"Go to die!"

“No surrendered

”

On the Chinese position, three people strongly refused. Although the Indian lieutenant didn't know the content, there were some things that didn't need to know. The intense words themselves meant everything.

"Okay, Chinese, let me end you with the way you treat heroes. Maybe this is your best destination."

The Indian lieutenant was a little regretful, but he still ordered: "Open fire!"

"Tututututututututututututututututututututututututututututu

A huge shadow enveloped him, and then several fire dragons easily swallowed him. A huge monster suddenly appeared in front of Pang Xingguo and others.

The largest helicopter made in China to date, the two wings of the Dragon-2, each with a propeller with a diameter of 35m. When they rotate, the propeller can touch the death zone as long as 67m, which is more than the length of all aircraft. Its maximum take-off weight reaches tons, and the original function of this helicopter is to act as a combat platform, and only the commander has the right to control it.

So far, only 2 Feilong-2 has been produced poorly and inconveniently, so there is no mass production.

Feilong-2 initially adopted a longitudinal rotor layout according to the requirements of the design task book. The existing components at that time were adopted. Later, the horizontal rotor layout was adopted. The rear rotor layout of the longitudinal rotor operates in the disturbing vortex area of ​​the front rotor, so the working conditions of the rear rotor are poor and the critical fatigue life of the rotor is low. The horizontal rotor layout structure is symmetrical, and the two pairs of rotors work under the same airflow conditions. It has good stability, reliability and fatigue life.

Feilong-2 created some effective load-altitude records. During the flight on 222, 1969, it carried 31,030 grams of effective load, at a height of 1802,951 meters, which broke the altitude record of climbing to 2,000 meters under the maximum load: |.0 grams, 25,000 grams and 30,000 grams of effective load.

Feilong-2 carries rockets and other heavy cargoes that large transport aircraft can carry. The cockpit vibration is low and there is no need for special ground equipment when performing missions.

The rotor system has two pairs of all-metal rotors with five blades similar to meter-6 or meter-10. The two pairs of rotors are installed side by side on the wing tips of the fixed wing. From the bottom view, the left rotor rotates clockwise and the right rotor rotates counterclockwise. Each rotor has a trailing edge adjustment piece. The two pairs of rotors installed horizontally ensure synchronization through the coordination axis. If the engine fails on either side, the two pairs of rotors can be kept rotating.

The rotor speed is 112 per minute. After the rotor system is working 900, intermediate maintenance will be carried out. The wing pillar-type upper single-wing structure has a large on-ground reverse angle and reverse sharpening ratio (i.e., the chord length from the wing root to the wing tip increases). The initial is three sections) long wingspan:=

The first three-point landing gear that cannot be retracted is not retracted. Each landing gear has two wheels, and the front wheel can be operated. The main wheel tire size is 1750x730 meters, and the front wheel tire size is 1200.

rice.

Powered by a 4o shaft engine, a single power of 4770 watts (force), :;.+| is used to drive a pair of rotors and have a coordinated shaft. The improved version of a-25bo::b engine has improved the compressor and increased the working temperature, increasing the power of 4040 watts (5500 axle horsepower) to watts (6500 horsepower). To facilitate maintenance of the power unit and the hub, the fairing side plates of each pair of engines can be opened downwards, and the lower fairing can be lowered by hand-cranking 1. The human maintenance platform. The cylindrical external fuel tank is installed on both sides of the cockpit.

The body has a full metal semi-hard shell structure, with clamshell cargo door and loading and unloading springboard at the rear. There are two shock absorbing pads under the springboard.

The tail device adopts a full metal structure, including the central main vertical fin horizontal tail surface, horizontal tail surface, elevator, and end plate auxiliary vertical tail surface. The horizontal civil surface has a large upside-back angle, and the front edge of the auxiliary vertical tail surface is offset to the inward direction. The elevator and rudder have adjustment plates.

There is a cockpit in the front of the cockpit, and the front and co-pilot seats are placed side by side in the cabin. The front and co-pilot seats are on the left and co-pilot seats are on the right. The back of the driver is a random mechanic, and the back of the co-pilot is an electrical technician. The above cockpit is a pilot cabin, and the navigator and the radio operator are arranged front and back. The windshield glass in front of the cockpit and the navigator cabin is equipped with wipers. There is a cooling fan with rubber blades in the cabin, which cools the crew.

There are about 50 pairs of upwardly folded seats along the side wall of the cockpit for people carrying cargo to sit and move. The crane has 4 lifting points c grams of cargo, and 4 lifting can lift 10,000 grams of cargo at the same time. The main passage is formed between the clamshell-type cabin doors at the tail, and the tail door can open downward and form a springboard for loading cargo. There is a rear-sliding hatch in front of the external fuel tank on the left. The emergency exit hatch doors on both sides are located at the rear of the cockpit. There are downwardly opened emergency exit hatch doors on the right side of the driver's cabin and the navigator cabin.

The system electrical system has a capacity of 480 watts. It has a standard damage safety assist control system and an automatic stability system, and can be manually operated and landed.

The bubble-shaped fairing at the lower part of the head of the onboard equipment is equipped with a terrain display radar. The power assist device is used to start the engine.
