About Ka-50 combat helicopter:
In developing the advanced Ka-50 combat helicopter in 1977 at the time the fleet of the Soviet Army’s combat helicopters was made up of Mi- 24s. In terms of performance they could not challenge the new American AH- 64 “Apache” fire support helicopter, which was at that time being developed. Several helicopter configurations and were studied, as “Kamov” designers tried to create a new superior combat machine. The experience in Vietnam and in Afghanistan had disclosed the low survivability of the classic single-rotor helicopter due to its vulnerable tail rotor and extended rotor drive.
The advantages of an aerodynamically symmetrical coaxial main rotor came to the fore. Such a rotor assures easier helicopter control both in the manual and, more importantly, automatic mode, excellent manoeuvrability, take-off and landing in windy weather. Furthermore, the coaxial rotor considerably improves helicopter survivability, makes the rotor drive more compact and substantially reduces engine power losses. Today, Ka-50 is the world’s best helicopter in terms of efficient use of engine power.You may find more details about this at breeze eastern hoist .
Many of us with no doubt can recall one of Russia’s MiG-29 and its world famous stunt aerobatics nicknamed “the bell”, or Su-27’s “Pugachov cobra”, which shock both experts and spectators. Ka- 50 also has its own aerobatic our de force: no other machine can execute the so-called “funnel” as perfectly as Ka-50. In actual fact, the “funnel” is an element of aerobatics, ensuring concentration of helicopter fire on pinpoint targets. Moreover, continuous displacement of the helicopter in the “funnel” in azimuth and elevation makes enemy timing extremely difficult. The Ka-50 can sideslip at 80 km/h or move backwards at 90 km/h. It only takes a few seconds to reverse flight direction. Ka-50 is the only craft in the world which can hover motionlessly for twelve hours in succession! The priorities of the “Kamov” company extend far beyond its unsurpassed experience in the theory and practice of building coaxial rotor helicopters. In 1965, the company started issuing fibre glass rotor blades in their helicopters ten years before the rest of the world. Similar fourth- generation blades are now being installed in Ka-50. One of the Ka- 50’s rotor blades sustained 30 holes caused by automatic gunfire to test the helicopter’s survivability. The craft continued flying for 80 accident- free hours.
The Ka-50’s combat power is based essentially on anti-tank guided missiles and cannon fire. Frequently, then a helicopter attacks tanks, it becomes a good enemy target. Ka- 50 is able to counter this menace with its “Vikhr” supersonic anti-tank missiles, with a maximum range of 10 km. This weapon helps reduce the time spent by the helicopter in the firing zone, exceeding at the same time the effective range of enemy anti-aircraft missiles. The combination warhead of the supersonic missile includes several different fuses. All these factors, combined with a high-accuracy jam-proof guidance system, ensures effective engagement of different targets, including armoured targets (with dynamically protected armour up to 900 mm thick) as well as airborne targets flying at a speed of up to 800 km/h, using the same type of ammunition. The missile is renowned for its stealth: the enemy only detects the attack when hit. This weapon is characterized by lower reserves, which may well be used to enhance its combat capabilities. Extensive firing tests have proved the excellent qualities of the automatic guidance system: small-size targets are defeated at maximum ranges far more effectively.
