The Kamow Ka-52 Alligator ( Russian Камов Ка-52 Аллигатор, NATO code name Hokum-B ) is a two-seat Russian attack helicopter with a coaxial rotor . It is a further development of the Kamow Ka-50 "Black Shark".

development

The Ka-52 was developed by Kamow as the successor to the Mil Mi-24 from the single-seat Kamow Ka-50 . While the first prototype had its maiden flight in 1997, series production did not start until October 29, 2008. Then the various prototypes were equipped with other systems. Production takes place at the AAK Progress aircraft plant in Arsenjew , Primorye region .

Since 2012, the production line has been designed in such a way that the complete construction, including inspections, takes nine months to complete. At the time mentioned, only six units were under construction at the same time, although an additional production line could be set up next door for export orders.

construction

Kamow Ka-52

In contrast to conventional combat helicopters, the two pilots in the Ka-52 do not sit one behind the other, but next to each other, which led to a widening of the fuselage nose. The two pilots each have a Zvezda K-37-800 ejection seat . The two ejection seats are part of an automatic rescue system, which in an emergency situation shoots out the two pilots within fractions of a second after the rotor blades have been blown off with the catapult seat. The cockpit is armored against anti-aircraft bullets up to 20 mm caliber.

The modern multi-function displays in the pilot's cockpit and the arrangement of the controls allow both pilots to control the helicopter. The drive components and the rear fuselage were taken over from the Ka-50. Two more suspension points were added at the ends of the stub wings. The six internal kerosene fuel tanks made of rubber / fiber material are lined with rubber coatings and polyurethane foam fillings to be explosion-proof. All drive rooms and the installation spaces for the fuel tanks are equipped with automatic fire extinguishing systems. The helicopter is constructed in such a way that it can be exposed to the weather all year round in arctic to desert-like areas. Following the tradition of the Soviet army aviators, the helicopters are only protected from the weather with a tarpaulin over the cockpit.

Range of use

During combat operations, the Ka-52 should lead groups of combat helicopters (Mi-24/35, the "Raduga-F" sensor of which has a maximum reconnaissance range of 5000 m) and assign the target. For this purpose, it is equipped with the new “Breeze” data link system, which can transmit video, image and radar data in real time to the group's attack helicopters.

The helicopter is primarily used for combat missions such as B. against enemy helicopters and anti-aircraft missile systems and secondarily also for training tasks related to the training of Ka-50 pilots. In order to be able to do without a flight simulator, a flight can be simulated via PC feed on the instruments and displays on the ground.

Originally, Ka-52 helicopter carriers of Mistral class are stationed. After the cancellation of the sales contract in the course of the war in Ukraine and the occupation of Crimea , Russia now wants to develop its own helicopter carriers.

Homing systems

A "Gyrostabilized Optical Electronic System" (GOES or gyro-stabilized electro-optical system) is installed in a swiveling cylinder below the nose cone directly in front of the nose landing gear. The JSC (formerly PA UOMZ) GOES-451 or the GOES-520 system includes the Samschit BM system and has various TV, RLV and WBG cameras, laser target lighting and range finders. In the bow there is a Fasotron-NIIR -Mjetsch-U millimeter wave radar device with the designation FH01 Arbalet-52. In the prototypes, the older system was installed in three spherical turrets (one above the cockpit and two under the nose). The multifunction radar “FH01 Arbalet” can also be carried in a rectangular container on the outer suspension station, which can locate air, ground and sea targets up to 15 km away and guide guided missiles to the target.

variants

Ka-52 "Alligator"

  • Pre-series machines that were still being tested with sensor balls on the rotor mast or in the nose.
  • Series machines with modified electronic equipment.

Ka-52K "Katran"

Marine variant for use on the helicopter carriers of the Mistral class with a weight- reduced but powerful Fasotron-Schuk-AE radar device in the bow and anti-ship guided weapons, the rotor blades and the stub wings can be folded up. The hull is made less susceptible to corrosion against seawater with special metal alloys. The cockpit was converted in such a way that the pilots with dry suits and diving rescuers can find space in it. In the event of an emergency, inflatable air cushions were automatically installed on the fuselage, preventing the helicopter from sinking immediately after a splash.
