Kamov Ka-50


The Kamov Ka-50 "Black 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. It was designed in the 1980s and adopted for service in the Russian army in 1995. The Ka-50 is manufactured by the Progress company in Arsenyev. It is used as a heavily armed scout helicopter and has a rescue ejection system, rare for helicopters.
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". The Ka-52's unit cost is US$16 million as of 2023.

Development

The Ka-50 is the production version of the V-80Sh-1 prototype. Production of the attack helicopter was ordered by the Soviet Council of Ministers on 14 December 1987. Development of the helicopter was first reported in the West in 1984, while the first photograph appeared in 1989. During operational testing from 1985 to 1986, the workload on the pilot was found to be similar to that of a fighter-bomber pilot, such that the pilot could perform both flying and navigation duties.
Like other Kamov helicopters, it features Kamov's characteristic coaxial contra-rotating rotor system, which removes the need for the entire tail rotor assembly and improves the aircraft's aerobatic qualities—it can perform loops, rolls and "the funnel", where the aircraft maintains a line-of-sight to the target while flying circles of varying altitude and airspeed around it. The omission of the tail rotor is a qualitative advantage, because the torque-countering tail rotor can use up to 30% of engine power. The Ka-50's entire transmission presents a comparatively small target to ground fire.
For improved pilot survivability the Ka-50 is fitted with a NPP Zvezda K-37-800 ejection seat, which is a rare feature for a helicopter. Before the rocket in the ejection seat deploys, the rotor blades are blown away by explosive charges in the rotor disc and the canopy is jettisoned.
Following initial flight testing and system tests, the Council ordered the first batch of helicopters in 1990. The attack helicopter was first described publicly as the "Ka-50" in March 1992 at a symposium in the United Kingdom. The helicopter was unveiled at the Mosaeroshow '92 at Zhukovskiy in August 1992. The following month, the second production example made its foreign debut at the Farnborough Airshow, where it was displayed with an image of a werewolf on its rudder—gaining the popular nickname "Werewolf". The fifth prototype, painted black, played the title role in the movie Чёрная акула, which made the Ka-50 known by its current nickname.
In November 1993, four production helicopters were flown to the Army Aviation Combat Training Centre at Torzhok to begin field trials. The president of the Russian Federation authorized the fielding of the Ka-50 with the Russian Ground Forces on 28 August 1995. The collapse of the Soviet Union led to a severe drop in defense procurement. This resulted in only a dozen Ka-50s delivered, instead of the planned several hundred to replace the Mil Mi-24.
The single-seat configuration was considered undesirable by NATO. The first two Ka-50 prototypes had false windows painted on them, which successfully misled the first western reports of the aircraft in the mid-1980s, to the point of some analysts even concluding that its primary mission was as an air superiority aircraft for hunting and killing NATO attack helicopters, an alarming but expected Soviet move by NATO planners following the recent J-CATCH program evaluation.
The Ka-50 and its modifications have been chosen as the special forces' support helicopter, while the Mil Mi-28 has become the main army's gunship. The production of Ka-50 was recommenced in 2006. In 2009, the Russian Air Force received three units built from incomplete airframes dating from the mid-1990s.

Ka-50N "Night Shark" and Ka-50Sh

From the time the Ka-50 was ordered in 1987, it was known that the limited night-time capability of the original version would have to be upgraded to meet night attack requirements. Initially, Ka-50N was meant to be fitted with the Merkury Low-Light TV system. Due to lack of funding, the system was late and experienced reliability and capability issues. As a result, focus shifted to forward looking infrared systems. Kamov drafted a design in 1993 that included the Shkval-N sighting system with an infrared sensor. Many variants were tried. On some, the original Shkval was supplemented by a thermal imaging system, while others saw a complete replacement by the Samshit day-and-night system. Some of the imagers included in the trials were manufactured by the French SAGEM and Thomson companies. Kamov was forced to consider foreign analogues as a temporary replacement for domestic imaging systems because of their slow development.
Trials led to two "final" versions: Ka-50N "Night Shark" and Ka-50Sh. The first Ka-50Sh, which was the eighth pre-production aircraft, Bort 018, first flew on 4 March 1997. The Kamov company and Black Shark logos were displayed on the endplate fins and the vertical tail. It featured the Samshit-50 system installed within a 640 mm diameter sphere under the nose. Shkval system was moved to the nose cone area. Neither of the Ka-50 night-attack versions has entered full production.

Ka-50-2 "Erdogan"

In 1997, Israel Aerospace Industries in cooperation with the Kamov bureau entered the Ka-50-2 Erdoğan in a Turkish design competition for a $4 billion contract for 145 combat helicopters.
The Ka-50-2 is a tandem cockpit variant of the Ka-50. It featured a modern, Israeli-made "glass cockpit" avionics and a turret-mounted folding 30 mm cannon instead of the fixed cannon on the Ka-50. It features combat-proven avionics and advanced anti-tank guided missiles for a high level of combat effectiveness. It is equipped with IAI's flexible modular avionics suite, which can be readily tailored to meet the TLF's operational requirements and provides growth potential.
IAI and Kamov performed flights of the variant with IAI's Core Avionics. These flights demonstrated the helicopter's "glass cockpit" with multifunctional displays and Control and Display Unit driven by centralized mission computers. Also tested were its flight navigation and the operation of the Helicopter Multi-Mission Optronic Stabilized Payload targeting system. The demonstration flights included night mission capability demonstrations using Night Vision Goggles and the day/night targeting system.
Turkey initially selected an improved version of the Bell AH-1 SuperCobra over the Erdogan, Eurocopter Tiger, AH-64 Apache, Denel Rooivalk, and A129 Mangusta. In the end, the contract was awarded to the A129 in 2007.

Ka-52 "Alligator"

In the early 1980s, while comparative tests of the V-80 and the Mi-28 were being conducted, the Kamov design team came up with a proposal to develop a dedicated helicopter to conduct battlefield reconnaissance, provide target designation, support and coordinate group attack helicopter operations based on the Ka-60. However, the economic hardships that hit the nation in the late 1980s hampered this new development program. This prompted Kamov's Designer General to choose a modified version of Ka-50 on which to install the reconnaissance and target designation system. The modified "Black Shark" required a second crew member to operate the optotronics/radar reconnaissance suite. Kamov decided to use side-by-side seating arrangement, due to the verified improvements in co-operation between the crew members. This twin-seat version was designated Ka-52.
In comparison to the original Ka-50, the Ka-52 has a new radome with a nose-mounted radar system for targeting giving the Ka-52 a rounder nose profile. A day-and-night TV/thermal sighting system is fitted in a spherical turret under the nose. The Ka-52 has the side-mounted cannon of the original Ka-50. It features six wing-mounted hardpoints compared to four on the Ka-50. To keep the weight and performance on par with that of the Ka-50, the armor and the capacity of the cannon magazine/feed were reduced. Also some flight parameters deteriorated: rate of climb dropped from 10 to 8 m/s and maximum positive load factor became 3.0 g. Most of the problems were solved by installing the new VK-2500 engine. The Ka-52 is approved for day, night and adverse weather conditions.
Manufacturing of the first Ka-52 airframe began in mid-1996. Series production was started in autumn 2008., the 696th Instructor and Research Helicopter Regiment, based at Torzhok, is operating eight helicopters, in varying degrees of capability and/or modification, for research and development. In December 2010, four new, series-production Ka-52s were delivered to the Air Base of the 344th Centre for Combat Training and Aircrew Conversion.
The first phase of the official tests was completed in December 2008 and after that permission was given for the production of an experimental batch for phase 2
Serial production of the Ka-52 began at the Progress Arsenyev Aviation Company plant in Arsenyev, Primorsky Krai by end of the 2008. After the completion of the state trials, the Ka-52 entered service in May 2011 with first operational units joining the Russian Air Force the same month. Under previous State Defense Procurement Plans, the Russian Armed Forces was to receive 2 experimental and 24 serial Ka-52s by 2012. The second long-term contract signed in 2011 worth 120 billion rubles is to provide the Russian Aerospace Forces with 146 Ka-52 helicopters in total until 2020. In February 2018, the Russian Ministry of Defence expressed an interest to purchase 114 Ka-52s of a new version within the new State Armament Program for 2018–2027.
