Mil V-2 Mil V-8 909 Moskvich announced in mid-1960. All have a 575 h.p. Ivchenko AI-26V radial engine, driving three-blade main and tail rotors. Improvements introduced on the Moskvich include all-metal rotor blades, hydraulically-powered controls and equip ment for day and night all-weather flying. The following data are for the Mi-lNKh: 9 Rotor diam, 45ft llin; length of fuselage, 39ft 8in; height, 10ft lOin; max gross weight, 4,9601b; empty weight, 3,9251b; max speed, 124 m.p.h.; cruising speed, 87 m.p.h.; vertical rate of climb at s.l„ l,280ft/min; hovering ceiling in ground effect, 10,825ft; normal range, 217 miles; max range with extra tank age, 310 miles. Mi-3 This helicopter is almost identical with the Mi-lNKh, but has a four-blade main rotor of increased diameter and other minor changes. • Rotor diam, 46ft llin; length of fuselage, 39ft 9in; height, 10ft lOin; gross weight, 5.1801b; empty weight, 3,9681b; max speed 124 m.p.h.; econ cruising speed, 62 m.p.h.; hovering ceiling in ground effect, 6,560ft; max range, 210 miles. Mi-4 ("Hound") This excellent helicopter has been standard equipment with the Soviet armed forces and Aeroflot for nearly ten years, and is the mainstay of Russia's thriving network of helicopter passenger services. It has also been exported in large numbers throughout the world. There are three versions, all powered by a 1,700 h.p. A.Sh-82V engine, driving a four-blade main rotor. Standard military model is the Mi-4, with an under-fuselage gondola for the navigator. The passenger-carrying Mi-4P has larger, square windows in the main cabin, which accommodates 8-14 passen gers, with rear toilet, wardrobe and com partment for 2201b of baggage. The agricultural Mi-4S has a large hopper in the main cabin, holding a ton of dust or 352 Imp gal of spray. The civil versions do not usually have the under-fuselage gondola, and are sometimes fitted with wheel spats. • Rotor diam, 68ft llin; length of fuselage, 55ft lin; height, 17ft; normal gross weight, 15,8751b; max speed, 130 m.p.h.; cruising speed, 99 m.p.h.; service ceiling, 16,000ft; range with 11 passengers and baggage, 155 miles. Mi-6 ("Hook") Since it was first announ ced in the autumn of 1957, the Mi-6 has displayed its unrivalled capabilities by setting up an impressive list of internation ally-recognized records, ranging from a speed record of 198.8 m.p.h. over a 15/25km course (since beaten by the HSS-2) to a payload-to-height record which involved lifting nearly ten long tons to 16,027ft. Although the main cabin can accommo date up to 120 passengers, with more comfortable seating for 70-80, the Mi-6 has been demonstrated so far mainly as a freighter, its long cabin and rear loading doors enabling it to transport quite large vehicles and military equipment internally. It is powered by two 4,635 s.h.p. Soloviev TB-2BM shaft turbines, and is fitted with small wings to off-load the five-blade main rotor in cruising flight. Max gross weight is about 86,0001b and rotor diameter approx 115ft. Mi-? ("Harke") First shown at last year's Tushino display was a flying-crane adap tation of the Mi-6, which made an impres sive debut carrying a prefabricated house between its stalky four-leg undercarriage units. The depth of the fuselage has been reduced considerably, giving a continuous flattened undersurface right back to the rear rotor pylon. To compensate for the loss of fuel tankage in the bottom of the fuselage, there is now a large external fuel pod on each side of the cabin. Speed being less important than payload, the crane lacks the small wings fitted to the Mi-6. Some idea of the capabilities of this immense aircraft have been given by an officially-recognized record flight in which it carried a payload of over 15 metric tons to a height of 2,000m (6,561ft). V-2 Soviet designers have not been slow in adapting their well-proven helicopter air frames to take advantage of the lightweight power of shaft turbine engines. The V-2, announced last autumn, provides an excel lent example of the extent by which this can increase payload and performance because, while retaining the basic airframe of the Mi-1, with no increase in overall dimen sions, it carries double the payload of the piston-engined version, with comfortable seating for six or eight people. The two small turbines, of unknown type, are mounted side-by-side above the cabin. V-8 Although this is basically a turbine- powered development of the Mi-4, the appearance of the earlier helicopter has been changed by putting the flight deck in the nose—where the engine is on the Mi-4—and lengthening the cabin to accommodate up to 24 passengers in airliner-type furnishing. The single 4,000 s.h.p. shaft turbine is mounted above the cabin and, as in many of the latest Western helicopters, the fuel tanks are now semi-external in bulges on each side of the fuselage. Aleksandir S. Yakoviev Yak-24 ("Horse") Although this big 40- seat tandem-rotor helicopter flew in 195 3, and has been seen at Tushino since 1955, it does not appear yet to have entered large-scale service. The Soviet armed forces use it in limited numbers for troop-carrying and freighting, and Aeroflot have demonstrated their use of it as a flying crane. But the only passenger-carrying version that has been widely-publicized is the Yak-24K, with de luxe seating for only nine passengers in a cabin of reduced length. This version is fitted with air-stairs and autostabilization equipment. All versions of the Yak-24 seen to date have had two 1,700 h.p. ASh-82V engines, driving four-blade rotors; but last year's Soviet Exhibition in London included a model of the 39-passenger Yak-24P, powered by two Ivchenko shaft turbines, which would appear a logical development. • Rotor diam, 79ft; length of fuselage, 80ft; height 23ft; max gross weight, 35,2751b; max speed, 109 m.p.h.; max cruising speed, 96 m.p.h.; service ceiling, 18,000ft; normal range, 125 miles.
