PZL

In the late 1970s, P.Z.L. Swidnik, in conjunction with the Allison Division of General Motors in the USA, developed an export version of the Mil Mi-2 fitted with two Allison turboshaft engines. Given the names Kania or Kitty Hawk, they were generally similar to the P.Z.L. Swidnik Mi-2, being conversions of production airframes. The first (SP-PSA) was flown on 3 June 1979 and was intended, like the standard Mi-2, to fulfil a variety of roles. It could accommodate a pilot and a maximum of nine passengers or, alternatively, pilot and copilot plus eight passengers, and the cabin seats were removable to allow use in the agricultural or air ambulance roles. Reconfigured it could carry up to 800kg of cargo, some externally slung. The number ultimately converted (to the Kania Model 1) is believed to have totalled four prototypes plus half a dozen definitive aircraft. Earlier, in August 1978, P.Z.L. Swidnik concluded an agreement with the Spitfire Helicopter Company of the US allowing them to market a modified version of the Kania in Western countries under the name Spitfire Taurus. This differed primarily from the standard Polish version by introducing uprated Allison 250-C28 turboshaft engines, each with a take-off rating of 373kW fed by a large common intake; revised nose contours and sporting a ventral fin. However, the company has since gone out of business, and it is not known if any conversions were completed.

PZL Swidnik Kania (Kitty Hawk)

Developed in collaboration with Allison in USA; two prototypes produced by converting Mi-2 airframes; first flight of first prototype (SP-PSA) 3 June 1979. Polish certification of the Kania was carried out in two stages.

The first took place in 1979-81 and resulted, on 1 October 1981, in a supplementary type certificate to that of the Mi-2. The second stage, concerning a considerably improved Kania Model 1 version, was carried out during 1982-86 under the leadership of Stanislaw I Markisz. Improvements included among others, redesigned cockpit and cabin layout, engine and flight controls as well as engine and transmission cowlings. On 21 February 1986 this version of the Kania was granted a separate type certificate as an FAR Pt 29 (Transport Cat. B) day and night SVFR multipurpose utility helicopter with Cat. A engine isolation.

Intended for passenger transport (with standard, executive or customised interiors), cargo transport (internal or slung load), agricultural (LV and ULV spraying/spreading/dusting), medevac, training, rescue, and aerial surveillance configurations.

Jane's Helicopter Markets and Systems

The Kania is an example of the interest shown by the Communist bloc in trying to sell its aeronautical products to the western world. On August 12, 1978, for example, the Polish aircraft export agency Pezetel signed an agreement with the Spitfire Helicopter Company of Media, Pennsylvania for the latter to sell in western markets the Mil Mi-2 general-purpose helicopter built by WSK-PZL Swidnik as the Taurus II. At the same time, thought was given to the production of an Mi-2 variant with American engines, and this has emerged as the Kania (or Kitty Hawk).

The engine selected for the Kania is the ubiquitous Allison 250 turboshaft. WSK-PZL Swidnik have worked closely with the Detroit Diesel Allison Division of the General Motors Corporation on the installation of the two 250-C20B turboshafts, to ensure optimum location at minimum weight. Each of the engines is rated at 420shp for take-off and 30 min, 400shp maximum continuous running, and 370shp maximum cruising power. Fuel tankage remains unaltered, compared with that of the Mi-2, at 600 litres, with provision for another 480 litres in optional auxiliary tanks.

Accommodation is provided at the front of the cabin for a pilot and co-pilot or passenger, on separate seats, with eight more passengers seated on two three-abreast benches and one double or two single seats at the rear of the cabin. The Kania is intended as a general-purpose helicopter, and so the seating is removable to allow the carriage of freight, agricultural equipment and litters. Access to the cabin is gained by a small door on each side of the forward fuselage, and a larger door on the left side of the passenger compartment's rear. To suit the type to western markets, the Kania is provided with a comprehensive array of western avionics. These include dual instrument lighting systems, pilot's cabin extension light and an adjustable landing light. Among the optional avionics are a King KWX-50 digital weather radar, and a KRA-10 radar altimeter. Standard instrumentation includes King KX-175BE com/nav, KR-85 digital Automatic Direction Finding equipment and KT-76 transponder. An interesting optional feature is a 16k VA AC generator for de-icing the pilot's windscreen and cabin heating and air conditioning.

The smaller size of the Allison 250-C20B, compared with the Isotov GTD-350P used on the Mi-2, has made possible a smaller engine installation, and the opportunity has also been taken to recontour the nose. Rotor diameter has been increased by 6cm compared with the 14.5m of the Mi-2. The overall effect has been a reduction in empty weight of 262kg, though maximum take-off weight falls by only 150kg.

Despite the lower power of the American engines, the performance of the Kania is comparable with that of the Mi-2 except in range, where the Kania appears to be superior by a small margin.
