Kamov V-60 / Ka-60 Kasatka (Killer Whale)
The original coaxial rotor, twin tail, single-engined V-60 won the Soviet Army lightweight helicopter and Mi-8 replacement competition against the twin-engined Mil Mi-36 in 1982.
Subsequently the design was considerably modified to achieve greater speed through adoption of a single five-blade main rotor of 13.5-m diameter and Fenestron-type tail rotor with eleven blades.
The polymeric composite blade is attached to the hub by a torsion bar. The airframe features large door openings on both fuselage sides, retractable three-leg energy-absorbing landing gear. The seats of the crew and the troopers are energy attenuating seats. The pilot-in-command is on the right-hand seat. The power plant of the helicopter is two modular-design engines developed by Rybinsk Motor Design Bureau, headed by Mr. A. Novikov, Designer General.
Particular attention is paid to the increased combat survivability means of the helicopter. All principal systems and units of Ka-60 are duplicated and separated. The composite polymeric materials that make about 60% of the helicopter structural weight add to the survivability of the helicopter being more resistant to the combat damages. The foam polyurethane that filled the tanks prevents the danger of the fuel explosion.
The basic avionics suite for all versions is the one for transport assault helicopter. This suite ensures operational missions in daytime and night, in VFR and IFR conditions.
All main systems and components are duplicated, with main and secondaries routed on opposite sides of airframe. The transmission is resistant to 12.7mm bullets, the main blades to 23mm shells. The gearboxes will run without oil. The main rotors are advanced technology with sweptback tips. Production versions were to have a slower-turning five-blade rotor. Undercarriage is a reverse tricycle. The Ka-60 has IR- and radar-absorbent coatings.
Accommodation is for up to 16 infantry troops or six stretchers and three attendants. The pilot (starboard) and co-pilot/gunner (port) sit side by side. There is provision for dual controls, with the control stick top common with the Ka-50/52. The cockpit has a three-screen EFIS. Avionics include a Pastel RWR and Otklik laser warning system, and an Arbalet MMW radar with an antenna in the nose.
The Ka-60 is fitted with a cargo hook.
Armament can be carried on a one-piece transverse boom through the cabin, to the rear of the doors, to provide suspension for total of two B-8V-7 seven-round 80mm rocket pods, two 7.62mm or 12.7mm gun pods, or similar armament.
The prototype has RKBM Rybinsk RD-600V Turboshafts, as the Ka-62, but the production engine was to be the 1,103kW Klimov VK-1500. RRTM RTM322 or GE CT7 were available in the export versions.
The first flight was originally due 1993, but the programme was slowed by funding shortages, and the priority changed to promotion of a civil variant (the Ka-62).
The Ka-60 was officially revealed at Lyubertsy on 29 July 1997, when the prototype was close to completion. The first (601) flew on 10 December 1998, made a second sortie on 21 December, and the first official flight on 24 December. All were hovering flights.
The international debut was at MAKS '99, Moscow, in August 1999. The first 'forward flight' was on 24 December 1999. Further testing was intermittent, due to irregular Ministry of Defence funding, but production versions of the RD-600V turboshaft were installed in mid-2002. At this time, it was stated only that the prototype had completed "several" flights, although State Trials were not due to begin until early 2003.
Conflicting reports quote both Arsenyev and Ulan Ude as prospective production lines. However, LMZ (later LAPIK, part of RSK "MiG") was reported in April 2000 to be preparing for production and in mid-2001 was building second prototype, which to be completed as a trainer in Ka-60U configuration. This entered final assembly in July 2002, although RD-600 engines became due to have been received late 2002. Displayed (marked as 602) at MAKS ‘03, Moscow, August 2003. Series production at LAPIK was due to begin in 2003.
The Ka-60U cost US$1.7 million in 2000. In August 2002, it was announced that power plant was to be changed to Klimov VK-1500 to increase participation by RSK "MiG" group.
A smaller variant of Ka-60 was reported in mid-2001 to have been offered to Russian Navy.
