Mil Mi-35




The development of the product design “240” (B-24) began immediately after the publication of the Decree of the Council of Ministers of the USSR and the Central Committee of the CPSU on May 6, 1968 at the Design Bureau of M. L. Mil, as first fire support helicopter in USSR, with accommodation for eight armed troops. Prototype machines (OP-1 and OP-2) were ready in a year. Significant part and assemblies were in common with the Mi-8 and Mi-14. Twelve prototypes were built with the first flown on 19 September 1969 (test pilot G.V. Alferov). The Mi-24 has the NATO reporting name 'Hind'.
The prototype helicopter had a common front two-seat cockpit (the so-called "veranda") with dual controls. Crew - pilot and operator. Later, a flight engineer was added to the crew. In the middle of the helicopter was a cargo compartment with a capacity of up to 8 personnel. On the right and left sides of the cargo compartment are double doors, with upper and lower wings. The opening windows were equipped with pivot mounts for firing during flight from personal weapons. Both cabs are sealed, supercharged by engines. Initially, the crew’s equipment included specialized flight helmets and body armor. Cabin reservation is represented by frontal bulletproof glass, armored crew seats, and local armored plates on the sides of the cabin and on the engine hoods.
Due to the unavailability of the Sturm weapons complex, it was decided on the first machines to equip the K4V complex of the Mi-4 helicopter - the Falanga-M missiles with a manual guidance system and the NUV-1 machine-gun mount with the A-12.7 machine gun, four beam holders under NUR or free-falling bombs.
Factory tests started on September 15, 1969 and almost immediately began the construction of an experimental series of ten helicopters. At the end of 1970, two machines were finished - to improve stability at speeds of more than 200 km / h, the helicopter was equipped with a wing with a negative V-12 degrees and an elongated cockpit. The first production helicopters Mi-24A (product "245"), designed in this form and equipped with the Falanga-M complex, entered the army for pilot operation.
First reported in the West in 1972, photographs became available in 1974 when two units of approximately squadron strength were based in East Germany. The Mi-24 uses the TV3 engines, transmission and rotor of the Mi-17 on a new fuselage, with stub wings carrying rockets and other offensive armament.
Two basic versions exist: the Hind A/B/C assault helicopter has a four-man crew under an extensive glasshouse canopy, while the anti-tank Hind D/E/F has a two-man crew under separate armoured glass canopies in a steel-plated forward fuselage. Both versions have stub wings to carry up to 1,500kg of stores, and eight combat equipped troops can be carried in the fuselage.
Mi-24A was produced by a factory in the city of Arsenyev. Almost 250 vehicles were built, which were put into service with the formed army aviation structures, in separate helicopter regiments of the combined arms armies and air assault brigades. On the basis of the Mi-24A, a trainer, the Mi-24U (ed. "244") was created with full dual control.
Mi-24B (ed. ”241 ″) received a new USPU-24 machine gun mount with a YakB-12.7 machine gun (4500 h / min), the Falanga-P missile system. But the helicopter's debugging was suspended and fundamental changes were made - the cockpit was converted into a tandem, the tail rotor and gearbox were mounted from the Mi-14 - the propeller became a pulling propeller, which sharply increased the efficiency of track control. The helicopter received the name "Mi-24V", or product "242". But due to the lack of knowledge of the Sturm complex, helicopters with a new cockpit had to be equipped with the Mi-24B type, and this "intermediate version" went into series under the designation Mi-24D (product "246"). Just in case, they decided not to use “G” ... It took 8 years to finish the Mi-24V. In 1976, the helicopter was officially adopted and was produced in the mass series.
Thus, by 1973, the appearance of a helicopter had developed, which had become widely known throughout the world.
Mi-24 is made according to the classic single-rotor scheme with a five-blade three-joint bearing and three-blade tail rotors.
The undercarriage is three-leg, retractable, with a s steerable front wheel. In the bow of the fuselage there is a double crew cabin according to the tandem scheme: the operator-gunner is in a separate front cockpit, followed by a pilot, whose cockpit is raised by 0.3 m above the cockpit nose, the flight engineer can be located on the folding seat in the equipment compartment behind the cockpit. The crew is housed in pressurized cabins equipped with a heating and ventilation system. To prevent the entry of contaminated air and radioactive dust into them, a slight overpressure is maintained
Steel plates were used to armor the crew cabin, gearbox, engine oil tanks, gearbox and hydraulic tank. The pilot's seat is armored, with a folding armored back and armored head, the nose is not armored, there is an armored partition between the cockpits, the windshields are armored, flat, equipped with wipers, the side convex glass is silicate, not armored.
The central section of the fuselage consists of a cargo compartment, which can accommodate up to eight paratroopers, and a rear cone-shaped part for equipment and niches for cleaning the main landing gear.
The transmission and the duplicated control system are the same as on the Mi-8 helicopter.
The rotor shaft is tilted not only forward by 4.5 degrees, but also to the right by 2.5 degrees. This ensures stability during forward straight flight.
One of the main features of the helicopter is a wing with an area of ​​6.75 sq.m. with a negative transverse V - 12 degrees., Which provides from 22 to 28 percent of the lifting force, depending on speed and other factors.
Especially for the Mi-24 in the late 1970s, the GUV-1 helicopter gondolas (including the AGS-17 Flame automatic grenade launcher) and the GUV-8700 (one Yakb-12.7 four-barreled machine gun and two four-barrel GShG-7.62 machine guns) were created .The Mi-24 is also capable of carrying two cannon containers UPK-23-250 with a GSh-23L gun and an ammunition load of 250 shells.
At the end of the 1980s, some Mi-24Ps received 2 R-60 / R-60M air-to-air missiles to repel the attacks of enemy fighters and to combat enemy helicopters. APU with missiles mounted on internal holders. The Mi-24 is also capable of carrying two cannon containers UPK-23-250 with a GSh-23L gun and an ammunition load of 250 shells.
At the end of the 1980s, some Mi-24Ps received 2 R-60 / R-60M air-to-air missiles to repel the attacks of enemy fighters and to combat enemy helicopters. APU with missiles mounted on internal holders.


Identified by Nato is the anti-tank Hind E, armed with AT-6 Spiral missiles. A version of the Hind E without the 12.7mm Gatling-type gun in the nose, but with a twin-barrel cannon pod attached to the fuse-lage side, has been named Hind F by Nato. Hinds have also been reported carrying air-to-air missiles.

The Mi-24D has a gunship configuration, with stepped tandem seating for two crew and heavy weapon load on stub-wings, the fuselage is wide eniugh to carry eight troops. Dynamic components and power plant was originally as the Mi-8, but soon upgraded to Mi-17-type power plant and port-side tail rotor.

R-60 (AA-8 'Aphid'), R-73 (AA-11 'Archer') and Igla air-to-air missiles fitted experimentally. Helicopter can be landed to install reload weapons carried in cabin. PKV reflector gunsight for pilot. Provisions for firing AKMS guns from cabin windows.

Reconfiguration of the front fuselage changed the primary role to gunship. The new version was first observed in 1977. In the early Mi-24A the pilot sat behind the armament operator and had relatively poor forward vision but the later Mi-24D provided a raised rear seating position for the pilot and a bubble nose for the weapons position.

The Mi-24 was used operationally in Chad, Nicaragua, Ceylon, Angola, Afghanistan, Chechnya and Iran/Iraq war, when at least one Iranian F-4 Phantom II destroyed by AT-6 (NATO 'Spiral') anti-tank missile from Mi-24. The Mi-25 was an export version of Mi-24D tandem-cockpit variant and Mi-35 as second and improved export variant based on upgraded versions of Mi-24. 

Low-rate production continued for export until 1994. Late models continued to be available from Rostvertol. By 1991 more than 2,300 had been built at Arsenyev and Rostov. An FAI record was set by the A-10 experimental variant of the 'Hind' on 2 September 1978 over a 15/25km course it achieved a speed of 368.4km/h.

The Mi-24 has been widely exported and a number are in service on most continents, with examples delivered to, or operating in, Afghanistan, Algeria, Angola, Bulgaria, Chad, Cuba, Czechoslovakia, Germany, Hungary, India, Iraq, Libya, Mozambique, Nicaragua, North Korea, Peru, Poland, Sri Lanka, Syria, Vietnam and Yemen.


Some export variants of the Mi-24 are designated Mi-25 and Mi-35, indicating a different equipment standard. The Mi-35M having fixed undercarriage.

The Mil Experimental Design Bureau demonstrated a fundamentally modernized derivative, designated the Mi-24VM (Mi-35M), of the Mi-24 helicopter that has made a perfect showing under complicated combat conditions. The features of the modernization consist in modular updating of the Mi-24. Any module (unit) can be individually modernized in accordance with the customer's request and financial potentialities.

Installation of a new main rotor provided with blades made of glass fiber plastics, a hub furnished with elastolar bearings, and an X-shaped tail rotor developed for the Mi-28N helicopter, makes it possible to decrease the mass of the flying machine, increase its hovering ceiling and rate of climb, and improve its overall operating characteristics and invulnerability.

In modernizing the airframe, armament system and communications facilities, the Mil Design Bureau offers to install a shortened wing and nonretractable landing gear and retrofit the hydraulic system. The primary emphasis has been placed on an increase of weapon effectiveness. The Ataka air-to-ground guided missiles (ammunition establishment has been increased up to 16 missiles) have been introduced into the helicopter's armament system. The missiles can also be used against air targets similar to the Igla-V guided missiles. The 12.7mm machine-gun mount has been replaced by a 23mm aircraft cannon. The most up-to-date BVK-24 computer and a laser range finder have been introduced into the heliborne equipment. A modernization program on this scale makes it possible to increase the accuracy against a single target 1.5 times, while increasing the kill zone 2 to 2.5 times when delivering cannon fire. The combat effectiveness of employing the guided missiles increases twofold on average.

The use of night-vision goggles with flight information displayed in the field of view, and equipping the helicopter with an optronic fire-control station comprising of thermal imaging and TV channels, control channel, and laser range finder, as well as display systems, enables the crew to detect and recognize targets at night and employ the heliborne weapons both by day and night.
