Hind ( Mi-24 )
The Mil Mi-24 is a large combat
helicopter, a gunship, and low-capacity troop transport
operated from 1976 by the Soviet Air Force, its
successors, and over thirty other nations.
Its NATO reporting name is Hind, variants are identified
with an additional letter, the export versions - the
Mi-25 and Mi-35, are denoted as Hind D and Hind E
respectively. Soviet pilots called the aircraft the
'crocodile'.
The core of the aircraft was taken from the Mil Mi-8, two
top mounted turboshaft engines driving a mid-mounted 17.3
m five-blade main rotor and a three blade tail rotor. The
engine positions give the aircraft its distinctive double
air intake above the equally characteristic tandem
cockpit. Other components of the airframe came from the
Mi-14. Weapon hardpoints are provided by two short
mid-mounted wings (which also provide lift), each
offering three stations. The load-out mix is mission
dependant, the Hind can be tasked with close air support,
anti-tank operations, aerial combat. The body is heavily
armoured and the titanium rotor blades can resist impacts
from 12.7 mm rounds. The cockpit is overpressurized to
protect the crew in NBC conditions. The craft uses a
retractable tricycle undercarriage.
The comparatively high size and
weight of the Hind limit its endurance and
maneuverability. In tight banking turns it can roll
alarmingly as the wings lose lift - this was noted during
test-flights in 1969 but has still not been entirely
eliminated. To counter this vulnerability the Russians
operate the aircraft in pairs or larger groups, with
attacks carefully coordinated to strike from multiple
directions simultaneously. Another weakness was the
possibility of the main rotor striking the tail-boom
during violent maneuvers. Its high loaded weight can also
limit its effectiveness as a helicopter, some reports
state that with a full load the Hind needs a rolling
take-off and also cannot hover. The problems with the
dual-role Hind have prompted the development of the Mil
Mi-28 and also the Kamov Ka-50 to replace it in the
gunship role.
The aircraft was operated extensively during the Soviet
invasion of Afghanistan. The US supplied 'Stinger'
missiles to the Mujaheddin and the Hind was a favourite
target - around 300 were lost during combat operations in
Afghanistan, an unknown number to missile hits.
Initially modelled on the Bell AH-1 Cobra and borrowing
extensively from existing models the Hind went from
drawing board in 1968 to first test-flights in less than
eighteen months. First models were delivered to the armed
forces for evaluation in 1970. The Mi-24A did have a
number of problems - lateral roll, weapon sighting
problems, and limited field of view for the pilot. A
heavy redesign of the aircraft front section to create
the Mi-24B solved some of these problems. The most common
variant is the Mi-24D, a purer gunship than the earlier
variants, the first to include the electronics for ATGMs,
most of the earlier models were upgraded to the D type.
The newest variant is the 1995 Mi-24VM, with light-weight
fibre main and tail rotors to improve all-round
performance, updated avionics to improve night-time
operation, new communications gear, shorter and lighter
wings, and updated weapon systems to include support for
the Ataka, Shturm and Igla-V missiles and a 23 mm main
gun. Other internal changes have been made to increase
the aircraft life-cycle and ease maintenance. The Mi24VM
is expected to operate until 2015.
Since 1978 around 2,000 Hinds have been manufactured, 600
for export.
