The Ka-52 will make a good attack helicopter for the Russian military . The Kamov Ka-50 “Black Shark” (Russian: Чёрная акула; Chornaya Akula Black Shark, NATO reporting name: Hokum A) is a single-seat Russian attack helicopter with the distinctive coaxial rotor system of the Kamov design bureau. It was designed in the 1980s and adopted for service in the Russian army in 1995. It is currently manufactured by the Progress company in Arsenyev. It is being used as a heavily armed scout helicopter.
During the late 1990s, Kamov and Israel Aerospace Industries developed a tandem-seat cockpit version, the Kamov Ka-50-2 “Erdogan”, to compete in Turkey’s attack helicopter competition. Kamov also designed another two-seat variant, the Kamov Ka-52 “Alligator” (Russian: Аллигатор, NATO reporting name: Hokum B).
Ka-50 and the two-seat version Ka-52, are high-performance combat helicopters with day and night capability, high survivability and fire power, to defeat air targets and heavily armoured tanks armed with air defence weapons. It was designed to be small, fast and agile to improve survivability and lethality.
The coaxial rotor design provides a hovering ceiling of 4,000 m and vertical rate of climb of 10 m a second at an altitude of 2,500 m. The rotor blades are made from polymer materials. The coaxial-rotor configuration results in moments of inertia values relative to vertical and lateral axes between 1.5 to two times less than the values found in single-rotor helicopters with tail rotors. Absence of the tail rotor enables the helicopter to perform flat turns within the entire flight speed range. A maximum vertical load factor of 3.5 g combined with low moments of inertia give the Ka-50 a high level of agility. Flight systems include inertial navigation system (INS), autopilot and head-up display (HUD). Sensors include forward-looking infrared (FLIR) and terrain-following radar.
