MI-24 D |
Mi-24D of Hungarian Air Forces
|
El HIND D presenta un fuselaje delantero completamente diferente, reduciendo la cantidad de tripulantes de tres personas a dos, fuertemente armado con gruesos vidrios a prueba de balas. La nueva versión mantiene el resto de la estructura de los Hind A, incluyendo el motor TV3-117 y la capacidad de transportar pasajeros. Un operador de armamento se encuentra sentado en la cabina delantera y el piloto se sienta en la cabina superior. Los helicópteros armados son normalmente antiestéticos pero en una competencia, el Mi-24D ganaría con facilidad entre los mas desaliñados. El sistema del rotor esta construido de titanio permitiéndole soportar disparos de hasta 20 mm. El armamento fue mejorado con cuatro Yakoushev-Borzov "YakB-12.7", con un rango de tiro de 4000 rondas por minuto. Las alas fueron reforzadas para poder llevar armamento mas pesado y puede llevar tanques externos de combustible. Otros cambios incluyen un tren de nariz mas largo para proporcionarle mayor espacio para los sensores y la nueva ubicación de la cámara de tiro de la raíz del ala a la puntera de la misma. Dos prototipos del Mi-24D fueron construidos en 1972 convertidos desde dos viejos Mi-24 A. Estas máquinas retuvieron el rotor de cola del lado derecho, pero los fabricados posteriormente poseen el rotor del lado izquierdo. La producción comenzó en 1973, con unos 350 construidos hasta 1977. VERSIONES del MI-24 Casi todas las viejas versiones del HIND A, B y C han sido mejoradas o modificadas al HIND D o al HIND E estándar.

The Hind-A demonstrated some drawbacks in service. Firepower was inadequate, while the Hind-A's cockpit provided surprisingly poor visibility and little protection for the crew. After working on a set of "Mi-24B" prototypes that were essentially Mi-24As with improved weapons and sensors, the Mil OKB decided to abandon that line of work and move on to a more drastic modification, the "Mi-24D Hind-D". The
Hind-D featured a completely revised forward fuselage arrangement
that reduced the crew from three to two and featured twin, heavily armored
cockpits with thick armor-glass canopies. The new variant retained the
rest of the structure of the Hind-A, including the TV3-117
turboshafts and the ability to carry passengers. A gunner / weapons
operator sat in the forward cockpit of the Hind-D, climbing in and
out through a panel on the left side that hinged upward. The pilot sat in
the stepped-up rear cockpit, entering and leaving through a car-style door
on the right side that opened towards the rear. Helicopter
gunships are normally ugly, brutish machines, but if there was an mean and
ugly competition, the Mi-24D would probably win it hands down.
Despite its ugliness, the revised fuselage cut down the frontal area of
the gunship, reducing its vulnerability and improving performance. The
rotor system was hardened with titanium to allow it to withstand 20
millimeter cannon hits. Armament was improved to a four-barreled
Yakoushev-Borzov "YakB-12.7" gun, with a rate of fire of about
4,000 rounds per minute and an ammunition store of 1,470 rounds of 12.7
millimeter ammunition. The gun was fitted in a nose turret with a traverse
from 15 degrees up to 60 degrees down, and 70 degrees to either side. The
gun could also be fixed forward so it could fired by the pilot through a
fixed gunsight. The stub wings were reinforced to handle heavier weapons
loads, and the pylons were "wet" to allow carriage of external
tanks. A
large air data boom was fitted in front of the gunship to provide inputs
for accurate sighting of weapons in the face of sidewinds and maneuvers. A
turret containing an electro-optical sight, with low light level TV and an
infrared imager, plus a laser rangefinder, was mounted behind and to the
right of the gun turret, while a pod carrying an AT-2 missile control
system was mounted behind and to the left. The
9M17M Falanga-M AT-2, which the operator had to fly to the target
manually, was upgraded to the "9M17P Falanga-P" AT-2, with range
increased from three to four kilometers (1.85 to 2.5 miles) and a
semi-automatic guidance system. All the operator had to do with the new
version of the missile was keep the crosshairs of his sight on the target.
The kill ratio increased from about 30% to over 80%. Other
changes included longer nose gear to provide additional clearance for the
sensors, and repositioning of the gun camera from the wingroot to the
wingtip, as rocket launches had fouled the camera lens in its original
position. Two Mi-24D prototypes were built in 1972 as conversions of early Mi-24As. These machines retained the right-side tail rotor, though all production Hind-Ds had left-side tail rotors. Production began in 1973, with about 350 built to end of manufacture in 1977. Thanks to http://www.vectorsite.net for the information VERSIONS Mi-24
