Figure 1-18. Medium Helicopter Mi/17/HIP H.
The Mi-17/HIP H is an improved version of the Mi-8T. It has the same airframe and main rotor as the
Mi-8T, but has its tail rotor mounted on the left side of the vertical stabilizer rather than on the right.
The HIP H also has an uprated powerplant: two 1,900-shp turboshaft engines. The HIP H may also
carry a strap-on IR decoy flare dispenser. As with the Mi-8, the OPFOR produce the Mi-17 in various
civil and military versions. On armed versions, the 12.7-mm nose machine gun is moved somewhat
higher than on the HIP E and F, to the center of the fuselage, and the outriggers support three weapon
stations on each side of the fuselage, normally mounting 32-shot 57-mm rocket pods. Unlike the HIP E
and F, the HIP H has not appeared with ATGMs.
The HIP H can perform a variety of military roles: assault transport, cargo transport, and air ambulance.
As an assault helicopter, it can carry up to 24 troops and 1,000 kilograms of ordnance simultaneously.
It can be rapidly converted into a cargo transport and can carry 4,000 kilograms of cargo internally or
3,000 kilograms as a slung load. As an air ambulance, it can carry 12 litters and the necessary medical
equipment. Men and material weighing up to 150 kilograms can be recovered with the aid of the
external winch about the side door.
Although its lift capabilities are essentially the same as the Mi-8T's, the Mi-17 has greater performance
in terms of speed and range. With a 4,000-kg payload, it can attain a speed of 240 kilometers per hour
and a range of up to 460 kilometers. Its maximum speed is 250 kilometers per hour; with normal
takeoff weight, the flight range is 495 kilometers without auxiliary fuel tanks and 950 kilometers with
auxiliary tanks. If one engine fails, the output of the other increases automatically to a contingency
rating of 2,200 shp. The HIP H is organic to division-level helicopter squadrons, army-level attack
helicopter regiments, and the medium-lift squadron of front-level transport helicopter regiments.
The Mi-17/HIP H was first seen at the Paris Air Show in June 1981. Civil as well as military versions
have small, round windows. Exported armed assault versions mount 23-mm machine gun pods on the
center pylon mount and 32-shot 57-mm rocket pods at the inner pylon position.
