The Kamov Ka-126 (NATO reporting name Hoodlum) is a Soviet light utility helicopter with co-axial rotors. Evolved from Ka-26 with engine pods removed from stub wings, fitted with one TVO-100 turboshaft engine positioned on top of fuselage, modified rotor blades, new fuel system.

Development

Development began 1984 with the signing of governmental Romanian-Soviet agreement in the field od aeronautical construction for cooperation in manufacturing an utility helicopter derived from Kamov Ka-26 helicopter.In October 1985 the signing of the collaboration protocol for the manufacturing of the single engine turbine powered KA 126 helicopter. In 1986 Industria Aeronautică Romx¢nă(IAR) starts the helicopter manufacturing preparation. Early mockup had two small turboshafts above cabin; single turboshaft adopted subsequently; ground test vehicle completed early 1986; In 22 December 1988 was maiden flight of the IAR Built Ka 126 with TV100 engine produced by Turbomecanica București and VR126 main gear built by I. Avioane Bacau today Aerostar. After building 17 ka 126 production was stopped and after 1991 the program was cancelled.

Proposed Ka-128, differing only in power plant and addition of an intermediate gearbox, has been abandoned.
A variant with a two engine was developed in Ka-226.

All the Ka-26/126/128/226 variants are codenamed "Hoodlum".

The fuselage of the Ka-126 consists of a fixed, bubble-shaped cockpit containing the pilot and co-pilot, plus a removable, variable box available in medevac, passenger-carrying and cropduster versions. The helicopter can fly with or without the box attached, giving it much flexibility in use. Compared with Ka-26 has turboshaft engine, significant increase in payload/endurance/range, and greater year-round utilisation; updated equipment includes new low-volume spraygear. Contrarotating coaxial three-blade rotors; hinge rotor head with 'rake'-type blade attachment. Load-carrying rear section and electrothermal anti-icing; rotor brake standard; non-folding blades. Three-stage gearbox with planetary gear trains, of alloy steel and aluminium casting, flange mounted with four load-carrying bolts. Accessories include cooling fan, hydraulic pump and AC generator; engine input 6,000rpm. Non-retractable four-wheel type landing gear. Main units, at rear, carried by stub-wings. All four units embody oleo-pneumatic shock-absorber. Forward wheels of castoring type, self-centring, no brakes. Rear wheels have pneumatic brakes. Mainwheel tyres size 595 x 185 mm, pressure 2.45 bars; forward wheel tyres size 300 x 125 mm, pressure 3.43 bars. Skis optional. Provision for large inflatable pontoons, across front of aircraft forward of front wheels and under each mainwheel.

POWER PLANT: One 522kW Mars (Omsk) TV-O-100 turboshaft, installed centrally in streamline fairing above cabin. Electronic-hydraulic automatic two-channel control system, with manual control in case of electronic governor failure. Front driveshaft with plate coupling to gearbox. Fuel in two forward and one aft tank, total capacity 800 litres. Provision for two external tanks, on sides of fuselage, total capacity 320 litres. Single-point main tank refuelling, on port side of aft tank.

ACCOMMODATION: Fully enclosed cabin, with rearward-sliding door each side; normal operation by single pilot; second seat and dual controls optional. Cabin ventilated, and warmed and demisted by air from combustion heater, which also heats passenger cabin when fitted. Air filter on nose of agricultural version. Space aft of cabin, between main landing gear legs and under transmission, can accommodate variety of interchangeable payloads. Cargo/passenger pod accommodates four or six persons on folding sidewall seats, with provision for seventh passenger beside pilot; two clamshell doors at rear of pod, emergency exit each side and hatch in floor. Ambulance pod accommodates two stretcher patients, two seated casualties and medical attendant. For agricultural work, chemical hopper (capacity 1,000 litres) and dust spreader or spraybars are fitted in this position, on aircraft's CG. Aircraft can also be operated with either an open platform for hauling freight or hook for slinging loads at end of a cable or in a cargo net.
