Mil Mi-28 Havoc



Designed during the 1970s to replace the Mi-24 Hind as the main attack helicopter of the Red Army.

The helicopter design is based on the conventional pod and boom configuration with a tail rotor. The pilot and the navigator/systems officer are accommodated in two separate cockpits in tandem configuration under individual canopies.

The fuselage of the Mi-28 has a bay fitted with a hatch door. The helicopter has non-retractable tricycle tailwheel type landing gear. The energy absorbing landing gear and seats protect the crew in a crash landing or in a low-altitude vertical fall. The crew are able to survive a vertical fall up to 12 metres per second.

In August 1996 Mil rolled out a prototype of the day and night capable version, the Mi-28N Night Havoc

Mi-28

The Mi-28A helicopter is powered by two TV3-117VMA turboshaft engines, fitted on either side of the fuselage. It is equipped with an auxiliary power unit for self- contained operation. The thermal signature of the helicopter has been reduced by a factor of 2.5x compared to its predecessor, the Mi-24.

The main rotor head of the Mi-28 has elastomeric bearings and the main rotor blades are made from composite materials. The tail rotor is designed on a biplane configuration with independently controlled X-shaped blades. The turnable stabilizer is fitted asymmetrically on the end of a tailboom. In real combat missions the single rotor design allows the helicopter to continue flight and land with damaged main rotor blades or damaged anti-torque blades in the majority of cases. A new design of rotor blade, all plastic with swept shaped tips has been installed on the Night Havoc Mi-28N helicopter. The new blades can sustain hits from 30 mm shells.

The crew have two compartments separated with armoured partitioning, the pilot seated in the higher rear compartment and the navigator/systems officer in the front compartment..The Mi-28 has a fully armoured cabin including the windshield which withstands impact by 7.62 and 12.7 mm bullets and 20 mm shell fragments.
