Russian Navy new Ka-52K Hokum B Naval Attack Helicopter to Undergo Wind Tunnel Tests
 
Russia’s Kamov Ka-52K helicopter will undergo tests in a landscape wind tunnel before joining the Navy’s air arm, Deputy Head of the Krylov Research Center Hydroaerodynamic Department, Candidate of Physical and Mathematical Sciences Sergei Solovyov told TASS on Tuesday.

The Ka-52K Katran helicopter is a ship-based version of the Ka-52 (NATO reporting name: Hokum-B) reconnaissance and attack helicopter.

"Works on the Ka-52K helicopter will be conducted to determine optimal glide path approaches for landing on the ship to avoid emergency situations caused by a drop in the lifting power. Such situations may result in an emergency crash landing of the ship-based rotorcraft," Solovyov said.

Vortex shedding from the ship’s superstructure causes a stagnant flow resulting in a lift reduction. In this situation, a helicopter may fall onto the ship’s deck, if the pilots lack proper training practice and experience.

The landscape wind tunnel allows developing a model to calculate velocity fields above helicopter pads on the decks of both warships and icebreakers and other civilian vessels.

The wind tunnel tests help calculate a safe landing (glide) path for helicopters of various types as each aircraft has its own response to upwash and downwash angles.

The Ka-52K helicopter is a ship-based version of the Ka-52 reconnaissance and attack helicopter. Unlike the baseline helicopter, the Ka-52K rotorcraft features folding main rotor blades and wing panels. The Ka-52K helicopter has reinforced landing gear.

The helicopter is capable of launching Kh-38 and Kh-35 cruise missiles. Previously, these missiles could be launched only from the board of Mikoyan MiG-29K/KUB (Fulcrum-D) ship-based multipurpose fighter jets or aircraft of the Sukhoi Su-30 (Flanker-C) family.
