Ka-50 "Black Shark" gunship (Ka-50) is a Soviet and Russian single-seat twin- engine coaxial twin-screw rotor multi-purpose gunship. It is the Mi-28 gunship of the Soviet Kamov Design Bureau and Miri Design Bureau. The result of the competition was completed by the Kamov Design Bureau in 1977. It flew for the first time on June 17, 1982. It first publicly participated in the Farnborough Air Show in England in 1993. The Ka-50 gunship has been installed since the beginning of the century. It is the world 's first coaxial counter-rotating propeller gunship and the world's first close-support gunship with a single cockpit. It is also the first helicopter equipped with an ejection life-saving seat. The helicopter designation standard belongs to the third-generation level. As Russia's next-generation anti-tank helicopter, thanks to the heavy-duty military specifications, it can also be used to perform tasks such as anti-ship, anti-submarine search and rescue, electronic reconnaissance and other tasks. The Ka-50 is designed to be small, light and flexible. The helicopter with great survivability and attack power is designed to achieve maximum speed and agility in the smallest and lightest range. It is also the only one-man-operated attack helicopter. The Kamov Design Bureau came to a conclusion after the end of the Soviet-Afghan war . The helicopter must automatically perform low-altitude flight to capture the target weapon launch and navigation and other mechanical actions without the driver's intervention. These operations only need to spend time on the task content. However, this is still an unsolved problem because many drivers of the Ka-50 The driver still feels that the overall workload during driving is not small. Later, the Ka-52, which was greatly remodeled, returned to the two-seat Ka-50. The overall outline of the Ka-50 is also smaller to reduce the probability of being hit. The fuselage is shorter, and the Kamov ensures its coaxial rotor. It can still operate after being hit by weapons of caliber below 23mm. Because the two wings rotate in opposite directions, the zero force distance effect can minimize the interference of wind on the Ka-50 and has extremely high maneuvering and hovering efficiency at any speed. Like other Kamov helicopters, the Ka-50 uses a coaxial inverting dual-rotor system that eliminates the rear tail rotor and improves aerobatics. Although it has caused an accident with the oars, the company has claimed that it can be gradually improved to pull the nose up and around. Loop Roll and "Funnel" This is a loop attack. When the body is aligned with the target axis, it can change the altitude airspeed and elevation angle while looping to attack the target. The limiting factor of extreme speed Using coaxial counter-rotating dual rotors means both rotors can run at lower speeds and with smaller rotors so dual rotors allow the Black Shark to surpass the top speed of the American AH-64 helicopter. Eliminating the tail rotor also has many benefits Because the stabilized tail rotor will consume 30% of engine horsepower and the tail rotor has been attacked, it has always been the main cause of helicopter battle damage The helicopter not only strengthens the Personnel survivability also increases the driver's psychological willingness to fight. When the under-seat rocket ignites, the explosion bolt in the center of the two sets of rotors blows all 6 rotors off the blades and separates a fraction of the blade sleeves on the mast (rotor hub). Seconds later, the canopy was ejected . The small white rocket above the flight seat was ignited and shot out . The rope at the lower end of the rocket was tied to the pilot's seat and pulled the seat out of the cockpit by the upward pulling force of the rocket. The pilot immediately separated from the seat and then opened the parachute to eject. The speed range is 90-350 km/h and the ejection height range is from 0 to 5000 meters. The entire escape process takes only 2.5 seconds. The Ka-50 can mount four weapons on the short wings. The wingtip can also mount two weapons with a total weight of not more than 2300 The main heavy weapon is twelve laser-guided 9K121 cyclone anti-tank missiles with a range of up to 10 kilometers. Automatically share all target information among four Ka-50s. One can scout and then pass the target to three hidden weapon launchers. It can also receive target information from ground bases or scouts. Built-in Shipunov 2A42 30mm cannon is semi-fixed on the right side of the fuselage and can only change a little angle, but it is a twin-rotor helicopter. The driver's helmet sight is as fast as the swivel turret of an AH-64 or Mi-28. The semi-fixed cannon's biggest consideration is the increased accuracy and the extra range you get from a longer barrel. The turret Ka-52 is a modified version of the Ka-50 that features side-by-side dual pilots and enhanced armament for helicopter combat. The rotor is similar to the original Ka-50, but the nose line is more rounded to accommodate two pilots . Some cockpit armor is reduced. And the nose radome space Ka-52 retains the design of the side cannon and six missile mounting points. Currently Russia is studying weapons and the Ka-52M with stronger weather resistance, which can launch long-range missiles . The disintegration of the Soviet Union affected the Ka-52M. Only a very small number of prototypes exist in the mass production of -52, but after the economy gradually improves, Russia intends to restart stable production. In addition to the use of the Ka-52 by the army, the amphibious ship is also equipped with the original equipment at that time and the Mistral-class amphibious assault purchased by the Russian Navy. On the ship, but it was stagnant because of sanctions by France after Russia occupied Crimea in 2014. It was finally sold to Egypt for use.
