Video Description:
The Mil Mi-28 (NATO reporting name "Havoc") is a Russian tandem two-seat anti-armour attack helicopter. It is a dedicated attack helicopter with no intended secondary transport capability, better optimized than the Mil Mi-24 for the anti-tank role. It carries a single gun in an undernose barbette, plus external loads carried on pylons beneath stub wings.In January 1988 the first Mi-28A prototype flew (no. 032). It was fitted with stronger engines and "X" type tail rotor instead of a standard three-blade variant. This new version debuted at the Paris Air Show in June 1989. In 1991 second Mi-28A was built (no. 042). The Mi-28A program was cancelled in 1993 because it was deemed uncompetitive with the Ka-50, and in particular, it was not all-weather capable. In 1990 the design bureau signed an agreement to export Mi-28A parts to Iraq and for assembly as the Mi-28L [citation needed], but these plans were disrupted by the Gulf War.
Yet another variant, the Mi-28N, was unveiled in 1995, the N designation meaning "night". The prototype (no. 014) flew on November 14, 1996. The most significant feature is a radar in a round cover above the main rotor, similar to that of the American AH-64D Longbow Apache. It also has improved To
r vision and aiming device under the nose, including a TV camera and FLIR. Due to funding problems, development was interrupted. A second prototype with an improved rotor design was unveiled in March 2004 at Rosvertol.The Mi-28 has two heavily armoured cockpits, a nose full with electronic equipment
s, and a narrow-X tail rotor. Two 2200hp Isotov TV-3-117VM. (t/n 014) X-type tail rotor (55 deg) to reduce noise. While the Mi-28 is not intended for use as a transport, it does have a small passenger compartment capable of carrying three persons. The planned purpose of this is to enable the rescu
e of downed helicopter crews. * Crew: 1 pilot (rear), 1 navigator/weapons operator (front) * Length: 17.01 m (55 ft 9 in) * Rotor diameter: 17.20 m (56 ft 5 in) * Height: 3.82 m (12 ft 7 in) * Empty weight: 8,095 kg (17,845 lb) * Loaded weight: 10,400 kg (22,930 lb) * Max
