Ka-52 HOKUM B
Black Shark / Werewolf
The KA-50 is a state-of-the-art and powerful battle helicopter which is in limited service with the Russian Air Force. This aircraft is not fielded. Only a handful of prototypes exist, and it has not yet been approved for full-scale production. There are two versions of the Hokum. The Ka-50 Hokum-A is a single seat close support helicopter and the Ka-52 Hokum-B two seat trainer and combat version.
The Mi-28N and Kamov Ka-50 are competing to fulfil the Russian Army Aviation requirement for a night-capable anti-tank helicopter, a replacement to the Mi-24 created 25 years ago.
The coaxial, contrarotating, three-blade main rotors are widely separated with swept-back tips, and there is no tail rotor. The equally tapered, short, stubby, weapon-carrying wings with end plates are mounted on the streamlined fuselage, which tapers to the front and rear. The fuselage, which is flat-bottomed except for the underbelly gun pod and sensor, features a flat plated glassed-in canopy. The tail is thick with a tapering tail boom and back-tapered tail fin with a square tip. The tail flats are high-mounted on the tail boom with end plates, and located forward of the fin. Twin turboshaft engines are mounted high on the fuselage above the stubby wings, with semicircular air intakes and exhausts that are turned outward.
The helicopter has a number of unique characteristics including single seat to increase combat and flight characteristics and reduce operational costs. It was designed for remote operations, and not to need ground maintenance facilities for 2 weeks. The airframe is 35% composite materials with a structural central 1m 2 keel beam of kevlar/ nomex that protects critical systems and ammunition. The fully armored pilot's cabin can withstand 23-mm gunfire, and the cockpit glass 12.7-mm MG gunfire. The Zvezda K-37-800 pilot ejection system functions at any altitude, and enables a successful ejection at low altitude and maximum speed.
External stores are mounted on underwing external hardpoints. Each wing has two hardpoints for a total of four stations. A typical mix for targeting armor formations is 12x AT-16 ATGMs, 500x 30-mm cannon rounds, and 2x 20-round pods of 80-mm folding fin unguided rockets. The 30-mm cannon is the same as on the BMP-2. It also carries guided air-to-air missiles IGLA-V (Needle C), already extensively tested and sold to buyers abroad. The Shark's avionics is largely in line with what is the norm for one-seater fighters and ground attack jets. It's most remarkable feature is a remote targeting system with a capability to provide for a sudden deadly attack from a distance that rules out direct visual contact with the target. The firing computer will turn the aircraft to keep the gun on target. It is equipped with downlink to provide information from the battlefield. The targeting and control system and weaponry enable accurate target engagement at ranges of up to 10km.
The KA-50 features unique maneuvrability and operating characteristics due to the contra-rotating co-axial rotors. The coaxial counter-rotating rotor system negates the need for a tail rotor and its drive system. Because of this, this aircraft is unaffected by wind strength and direction, has an unlimited hovering turn rate, and gives a smaller profile and acoustic signature, while allowing a 10-15% greater power margin. The HOKUM is fully aerobatic. It can perform loops, roll, and “the funnelâ€, where the aircraft will maintain a concentrated point of fire while flying circles of varying altitude, elevation, and airspeed around the target.
VARIANTS
Ka-50A/HOKUM A: Standard direct air support variant.
Ka-50N/HOKUM N: Night attack variant fitted with a nose-mounted FLIR. The cockpit is fitted with an additional TV display, and is NVG compatible.
Ka-52/HOKUM B: The “Alligator†is a side-by-side, two-seat cockpit variant of the Ka-50. The gross weight of the aircraft is greater, so the performance is marginally degraded. But airframe characteristics, dimensions, and armaments are relatively similar. It includes a mast-mounted millimeter wave radar covering the front quadrant only. It is used as an attack aircraft, and as a trainer for the Ka-50.
Beginning in 1997 Kamov company, in partnership with IAI, began competing in the tender for a $4 billion contract for the supply of 145 combat helicopters to the Turkish Army. In compliance with the tender requirements, KAMOV/IAI group submitted the required documentation on the Ka-50-2 Erdogan tandem twin-sitter in November 1999. On 06 March 2000, Bulent Ecevit, the Prime Minister of Turkey, announced that Boeing and Eurocopter, French/German company, would be excluded from the list of the Bidders for the combat helicopters supply contract. Among the remaining competitors for the contract award are KAMOV/IAI (Israel Aircraft Industries Ltd.) group with its Ka-50-2 Erdogan, Agusta company from Italy with its A129 Mongoose and Belltextron company from the USA with its AH-1Z King Cobra.

KA-50 BLACK SHARK ATTACK HELICOPTER, RUSSIA
The Ka-50 Black Shark helicopter, developed by Kamov Helicopters JSC, carries the NATO codename Hokum A, Hokum B being the two-seat version, Ka-52. Ka-50 is also known as Werewolf. It entered service in the Russian Army during 1995 and is in full production at the Sazykin Aviation Company Progress based in Arseniev Maritime Territory, Russia. A first batch of eight aircraft have been delivered, with further production orders expected. It is a high performance combat helicopter with day and night capability, high survivability and fire power to defeat air targets and heavily armoured tanks armed with air defence weapons.
A night attack version, Ka-50N, with Samshit-50T thermal imager, day TV and laser rangefinder has been developed, and Kamov has also joined with Israeli Aircraft Industries (IAI) to produce a version, the Ka-50-2 Erdogan that is compatible with NATO weapons and has an Israeli equipped cockpit.
DESIGN
The coaxial rotor design provides a hovering ceiling of 4,000 m and vertical rate of climb of 10 m/sec 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 being between 1.5 to 2 times less than the values found in single rotor helicopters with tailrotors. Absence of the tail rotor enables the helicopter to perform flat turns within the entire flight speed range. A maximum vertical g-load of 3.5 combined with low moments of inertia give the Ka-50 a high level of agility.
Extensive all-round armour installed in the cockpit protects the pilot against 12.7 mm armour piercing bullets and 23 mm projectile fragments. The rotor blades are rated to withstand several hits of ground-based automatic weapons.
The Ka-50 is the world's first operational helicopter with a rescue ejection system, which allows pilot to escape at all altitudes and speeds. The K-37-800 Rocket Assisted Ejection System is manufactured by the Zvezda Research and Production Enterprise Joint Stock Company in the Moscow Region.
WEAPONS
A combination of various armaments to a maximum weapon load of 2 tons can be selected according to the mission, including anti-tank missiles, unguided aerial rockets of different calibres, air-to-air missiles, guns, bombs and other weapons.
The helicopter has small mid-mounted wings fitted with four underwing suspension units and wingtip countermeasures pods. Up to 12 Vikhr supersonic antitank missiles can be mounted on the helicopter's two underwing external stores. The laser beamriding Vikhr missile is stated as having a target hit probability close to one, against a tank at a range of up to 8 km, and the capability of penetrating all types of armour including active armour up to 900 mm thick.
The Ka-50 is armed with a 2A42 quick-firing 30-mm gun which has an unrestricted azimuth and elevation range mounting for use against airborne or ground targets. The gun is equipped with 460 rounds of ammunition, two types being carried, high-fragmentation and explosive incendiary rounds and armour-piercing rounds. The pilot selects the type of ammunition in flight. The weight of the ammunition is 0.39 kg each round, the muzzle velocity is 980 m/s and the range is up to 4 km. The gun provides an angular firing accuracy of 2 to 4 mrad.
AVIONICS
Flight systems include inertial navigation system (INS), autopilot and head-up display (HUD). Sensors include FLIR (forward-looking infrared) and terrain-following radar.
COUNTERMEASURES
Ka-50 is fitted with radar warning receiver, electronic warfare system and chaff and flare dispenser.
ENGINES
The Ka-50 is powered by two TV3-117VMA turboshafts engines each providing 2,200 horsepower. The engines are placed on either side of the fuselage to enhance the combat survivability. The helicopter also has an auxiliary power unit (APU) for self-contained operation.

The development of this helicopter had started in year 1978 according to specifications annonced by Soviet Ministry of Defense in 1977. Codename V-80 was used till 1992, when the name Ka-50 was given to new Kamov helicopter. Kamov Ka-50 was designed for usage over the land, not for naval operations as almost all Kamov helicopters before (e.g. Ka-25 or Ka-27). The first model 1:1 was showed to Soviet Military Chiefs in May 1980. In two years on 17 June 1982 the first flight was accomplished. Kamov Ka-50 had serious competitor. Mil worked at the same time on brand new Mil Mi-28 (known as Havoc now). Both aimed to win the tender for new helicopter. When testing Ka-50 and Mi-28 helicopters, Ka-50 seemed to be better. Mil wished tests of helicopters repeated. Three times both types were tested, but Ka-50 was better in every test. Soviet Ministry of Defense decided to continue development of both competitors.
The development of the Ka-50 Black Shark and AH-64A Apache combat helicopters aimed to redress this disparity and make the helicopters able to defeat tanks armed with air defense weapons. The Ka-50 combat helicopter can be used to defeat targets on the battlefield within wide ranges of launching high-precision supersonic antitank missile systems, including launches from more than a 6-km range within a stand-off zone of air defense artillery and air defense missile systems. The Ka-50 combat helicopter is intended to defeat modern armored and mechanized materiel, air targets and hostile manpower. This co-axial helicopter features a high flight performance and ease of piloting via automated flight devices. It can successfully execute combat missions day/night owing to high survivability under hostile fire, powerful armament and comfortable pilot's cockpit. The helicopter was tested in simulated combat conditions. . The Ka-50 helicopter is unrivalled in the world in terms of the 'cost-efficiency' criteria. In 1995 the Ka-50 combat helicopter entered service and is now series produced at Progress Arsenyevsk-based aviation complex.
