Under the cover of night, a Mi-171 helicopter with its navigation lights turned off followed a stealth helicopter with an unclear outline and even no model.
Although no one knows what model or name this helicopter is. But in action, seagulls must have a name. At least the pilot of the aircraft must know that he is calling him.
So the special forces named this aircraft "Black Hole".
The reason for such a name is because this helicopter is really quiet and concealable.
The "Kilo"-class conventionally powered submarine designed and produced by Russia is commonly known as the "black hole of the ocean." The "Kilo"-class submarine is known as "the quietest submarine in the world today."
The "Kilo" class conventional submarine power plant includes two diesel generator sets, one propulsion motor and one economical cruise motor.
The diesel generator set can work on the water surface and in the snorkel state. The propulsion system is a single-shaft six-blade low-noise propeller. It is the only one in the Russian conventional submarine family that uses this drive method.
Due to the electric drive method, the diesel generator set provides power for charging the propulsion motor and battery pack. This method effectively reduces the mechanical noise. In order to further reduce the noise radiation of the hull, all power machinery and other noise sources are also installed On a platform called a "vibration-absorbing floating raft", it is isolated from the hull and a layer of special anechoic tiles is laid on the surface of the hull. This not only reduces the noise level of the hull to an extremely low level, but also Effectively avoid detection by active sonar. The noise level of the Kilo-class cruise is close to the background noise of the ocean.
This type of submarine is equipped with 6 533mm torpedo launch tubes. A total of 18 torpedoes are equipped in the boat. It also has a rapid mine loading system. The 6 launch tubes can complete the shooting within 15 seconds. They can be loaded after two minutes to implement the second Round strike. What's even more amazing is that the "Kilo" class can also be equipped with "Club" anti-ship missiles. This missile system includes the 3M54E1 supersonic anti-ship cruise missile. It can be launched from a torpedo launch tube and has a range of 300 kilometers. Greatly improved long-range strike capabilities.
The special forces chose such a name for their stealth helicopter because of its excellent stealth capabilities.
The special forces hope that this helicopter can hide in the night like a black hole and then launch an inescapable blow to the enemy.
To enter the mission area, the special forces must first pass through the forward positions of the "Titan" army.
Therefore, the helicopter can only choose a very secret route to go deep.
But at this moment, the special forces suddenly discovered a fire on the ground. Then a "Stinger" portable man-portable surface-to-air missile took off into the air.
"The Mi-171 is exposed. The 'black hole' raises the altitude." Wang Chaoyang said immediately when he saw that the reverse extension of the missile's trajectory was the location of the Mi-171.
The "Hound" immediately maneuvered the helicopter to stretch its height to avoid possible missile attacks.
In the cabin of the Mi-171, the red alarm light kept flashing and the alarm buzzer kept sounding.
"The missiles are coming," Andre shouted.
"Pay attention to dodge." The co-pilot shouted to the driver, and kept observing the position of the missile.
However, the Mi-171's huge body has limited its maneuverability.
Therefore, the missile is approaching quickly. What the helicopter can do is to turn as small a radius as possible to try to escape the lock of the incoming missile's detection radar.
The Mi-171 helicopter is a new helicopter designed by the Russian Mili Design Bureau and produced by the Russian Ulan-Ude Aviation Production Joint Company. It is a modernized and improved version of the famous Mi-8T and Mi-17. Its performance and reliability are better than the Mi-8T It has significantly improved the Mi-17. The development of the new aircraft began in 1988 and production began in 1991. It is planned to be continuously produced for 10 years. By October 1992, 36 aircraft had been produced. Six of them were exported to Germany, Colombia and Guinea-Bissau. .
The Mi-171 helicopter has a series of good and reliable performances. It has various modifications such as transportation, passenger transportation, cargo transportation, VIP, medical, firefighting, accident rescue, military transportation, etc. It is equipped with powerful TV3-117VM engine and AI-9 type Auxiliary power unit. In the latest modified helicopter, the latter will be replaced by the VK-2500 new engine that has been successfully tested. This will greatly improve the power ceiling, range, stability, safety and other performances of the helicopter. It can operate in extremely hot and thin mountain air. Perform complex tasks under conditions. After one engine fails, the other engine enters an emergency state in real time. Ensure that the helicopter (standard takeoff weight) climbs at a vertical speed of 0.8 meters/second. Then it flies horizontally for at least 60 minutes and lands safely. In addition .The helicopter can also be equipped with an auxiliary fuel tank inside or on the external plug, increasing the maximum flight distance to 1,300 kilometers.
Overall, the performance is very good. At least it is enough for a helicopter with similar uses as the "Black Hawk".
However, compared with special-purpose armed helicopters, transport helicopters and multi-purpose helicopters are slightly larger and have poor maneuverability, which cannot be compensated by powerful engines.
Specialized armed helicopters can perform many large overload maneuvers. But the Mi-171 cannot do it.
All the "Evil Spirit" special forces saw this "Stinger" missile hit the tail rotor of the Mi-171. The Mi-171 instantly lost control. It relied on inertia and the drive of the propellers to fly forward. At the same time, the fuselage rotated violently and fell toward the ground with a bump.
The FIM-92 Stinger missile is a portable air defense missile. It uses infrared guidance heat tracking and ultraviolet object tracking. It was developed by the United States and used by all US military forces. It has been in service since 1981. It has been confirmed that 270 aircraft and helicopters were shot down by the Stinger.
The Stinger missile is very easy to carry and operate. The Stinger is designed as a defensive missile. Although it is officially required to operate in a team of two, it can also be operated by a single person. The FIM-92B can attack ranges of 15,700 feet (4800m) and 12,500 feet. (3800m) altitude aircraft. It can also be mounted on an Avenger vehicle modified from a Humvee or an M2 Bradley infantry fighting vehicle (M2 Bradley IFV). It can also be carried by paratroopers and quickly deployed behind enemy lines. Helicopter-launched version Called ATA or AIM-92Stinger.
The missile body is 1.52m long, 70mm in diameter, and has a 10mm tail. The missile body weighs 10.1kg. It weighs 15.2kg (33.5 pounds) including the launcher. It is propelled by a small two-section solid rocket nozzle. The flames are at a safe distance behind the launcher. The maximum speed is Mach 2.2 (750m/s). The warhead is a 3kg penetrating warhead plus delayed fuze gunpowder.
When launching, insert the BCU (Battery Freezing Module) into the handle. This will inject a flow of argon gas into the system and energize the sight and missile. However, the battery only has a limited amount of gas and cannot be abused without maintenance. The battery will become unusable after a long time. The transmitter aiming antenna uses rechargeable batteries.
There are three extension types of stinger: basic type, passive optical type (POST), and software computer type (RMP).
The software computer model (RMP) provides the possibility of counter-countermeasures for the countermeasures systems often installed on fighter aircraft in recent years. Because it can load software and parameter tables that can be upgraded at any time, it can restrain various innovative countermeasures. It can also be inserted The default setting program is loaded into the ROM memory on the slot. If an error occurs in the software, the program in the ROM can be used to maintain basic missile functions. There are four CPU processors, each processor has 4KRAM memory; the program is loaded into RAM during operation. Therefore, There is not a lot of spare memory space, especially when running target search and analysis. The software computer-based RMP has dual guidance: infrared and ultraviolet tracking. Plus software control, it gives it a better chance of evading enemy countermeasures. The effectiveness of enemy aircraft is greatly different, especially compared with Redeye missiles that only have infrared rays.
Stinger missiles are produced under license from German EADS for use in Germany and Switzerland. Raytheon states that more than 70,000 Stinger missiles have been produced in the United States and 29 other countries.
"Help. Help. We're going to crash. We're going to crash."
A cry for help came from the Mi-171 on the radio.
"Hold on. We're going to crash." Andre firmly grasped the armrests to fix himself on the seat. He was ready to withstand the impact of the crash when it touched the ground.
Other signal flag special forces also began to prepare to crash.
"Go to the back of the woods and land. If we want to go down, it's them." Wang Chaoyang pointed to a forest on the ground and said to "Hound".
"Understood." "Hound" immediately adjusted its direction and flew towards the back of the woods.
After gliding through the woods, the Mi-171 spun and fell to the ground. Then it rolled violently, plowing a deep mark on the ground. Then it stopped by a dry creek. The helicopter's parts were scattered everywhere. land.
"Quick. Quick. Quick. Take action. Wang Chaoyang was the first to jump out of the landing helicopter. Then he squatted on the ground and raised his gun to guard the surroundings. At the same time, he urged the special forces behind him to get off the plane.
Special forces filed in from stealth helicopters.
"The 'Black Hole' is looking for a hidden spot to hide. It seems that we have to rely on our own legs to get in." Wang Chaoyang said to the "Hound" and then led the special forces in a battle formation. Heading towards the place where the Mi-171 crashed Rush to the place.
Andre pushed aside a broken blade fragment blocking the cabin door. Then he climbed out of the helicopter wreckage with his gun.
The helicopter's fuselage flashed with sparks from time to time. There were still fires burning in some places around it.
Both pilots died when they fell. Andre didn't know how many of his men died.
Andre knew that he was crossing the river like a mud Buddha and could not save himself. So he simply climbed out of the helicopter first, and then prepared to calm down before rescuing his team members.
Fortunately, the flying height was not high and the sitting position was better. So during the whole crash process, Andre did not suffer particularly serious injuries. They were just some skin injuries. He just felt a little stuffy from the fall on his chest. So take it slow.
"Speed up. Go through the woods and rush to the crash site." Wang Chaoyang said. "Silly monk, Gao Fei. You speed up. Rush to the crash site to investigate first. We will arrive soon."
So Sha Junlong and Gao Fei immediately left the team and moved quickly towards the crash site, passing through the woods.
The other special forces immediately adjusted their formation, filling the positions of Gao Fei and Sha Junlong, and then accelerated their search towards the crash site.
