The Kamov Ka-50 "Black Shark" (Russian: Чёрная акула, romanized: Chyornaya akula, English: kitefin shark), NATO reporting name Hokum A, is a Soviet/Russian single-seat attack helicopter with the distinctive coaxial rotor system of the Kamov design bureau.
A coaxial-rotor aircraft is an aircraft whose rotors are mounted one above the other on concentric shafts, with the same axis of rotation, but turning in opposite directions (contra-rotating). This rotor configuration is a feature of helicopters produced by the Russian Kamov helicopter design bureau.
Like other Kamov military helicopters it has coaxial rotors, removing the need for a tail rotor. In total, five prototypes and pre-series helicopters were built. Series production started at Kumertau in July 1979, and the new helicopter officially entered service with the Soviet Navy in April 1981. [1]
The tail rotor has about the same diameter and thrust as the four-bladed main rotor fitted to the MD Helicopters MD 500. [ 6 ] The Mi-26's unique main gearbox is relatively light at 3,639 kg (8,023 lb) [ 7 ] but can absorb 14,700 kilowatts (19,725 shp), which was accomplished using a non-planetary, split-torque design with quill shafts for ...
The Kamov Ka-31 (NATO reporting name Helix) is a military helicopter originally developed for the Soviet Navy and currently in service in Russia, China, and India in the naval airborne early warning and control role. As with all Kamov helicopters except the Ka-60/-62 family, the Ka-31 has co-axially mounted contra-rotating main rotors.
The Yakovlev Yak-24 (NATO reporting name "Horse") is a Soviet twin-engine, tandem rotor, transport helicopter developed by Yakovlev in the 1950s. The Yak-24 saw limited use in the Soviet Air Force, and the exact number produced and duration of service are unknown due to inconsistencies in data.
As there is a low rotor clearance at the aircraft front, it is approached from the rear when the rotors are turning. Due to the limitations of the Ka-26, USSR and Romania agreed under the Comecon trade to build a single-turboshaft engine version, the Kamov Ka-126 , with better aerodynamics and range.
