Mi-17 [Mi-8MT] HIP H
The Mi-17 helicopter, developed at the Mil Design Bureau. The designation Mi-17 is for export; the Russian armed forces called it Mi-8MT. The Mi-17 Helicopter is a medium weight, single rotor helicopter. The aircraft construction primarily incorporates the airframe of a Mi-8 with the power train of the Mi-24, which provides an increase in performance and gross weight over the basic Mi-8. The aircraft is configured with a five bladed main rotor system (70 ft diameter), and a wheeled landing gear.
The MI-17 is a multirole helicopter used to resupply CLF guerrillas or insert PSOC detachments. It can also be very heavily armed with an extensive array or rockets, misslies and guns. It is often used to air assault infantry forces to attack the point of penetration, reinforce units in contact or disrupt counterattacks. Additional missions include; attack, direct air support, electronic warfare, airborne early warning, medevac, search and rescue, and minelaying.
It is an improved development of the Mi-8. The airframe structure, transport capabilities and equipment are essentially identical with those of the Mi-8. There are some features which make it different from the Mi-8 - engine intakes have deflectors to separate solid particles in the air (sand, dust etc.) and prevent them from ingestion. The Mi-17 can be recognized because it has the tail rotor at the starboard side, instead of the port side. The Mi-17 added a number of improvements to its predecessor, including a vibration damper to increase comfort for crew members and passengers. It is equipped with an outstanding navigation and information system and state-of-the-art communication devices, which permit safe transportation of passengers even in very adverse weather conditions by day or night. The helicopter features a high thrust-to-weight ratio pair of TVZ-117MT or TVZ-117VM shaft-turbine engines with a takeoff power of 1,900 hp. The Mi-17 is capable of single-engine flight in the event of loss of power by one engine (depending on aircraft mission weight) because of an engine load sharing system. If one engine fails, the other engine's output is automatically increased to allow continued flight.
The basic version of the Mi-17 is used for military, police and civilian purposes. It is equipped with efficient self-defence means including IR jammer. The cockpit accommodates a crew of three. The cargo hold is 5.34 m long, 2.32 m wide and 1.8 m high. There is a large sliding door forward on the portside, and a clamshell freight-loading door in the rear. The landing gear is a non-retractable tricycle type with twin-wheel nose unit. On each side of the fuselage there is a pylon for an external fuel tank with a total capacity of 1830 litres both.
The Mi-17 is capable of carrying cargoes in the cabin (including long cargo) with half-open or removed doors, external loads, or passengers (24 people). The Mi-17 can carry up to 30 troops and up to 20 wounded; it can also be used for in-flight unloading of special cargoes. The transport version of the MI-17 helicopter is intended to carry cargoes (loads) in the cargo compartment, including long-size cargo with partially- opened or removed cargo doors, external loads, or executives (up to 24 persons). Interior seats are removable for cargo carrying. The rear clamshell doors open, an internal winch facilitates loading of heavy freight. Floor has tiedown rings throughout. The aircraft carries a rescue hoist capable to 150 kg.
External stores are mounted on weapons racks on each side of the fuselage. The Mi-17 has six external hardpoints. The Mi-17 is provided with missiles, bombs, small arms and cannons. It carries four missile launchers of the B8V20 type, with missiles launched with the aid of an on-board PUS-31-71 electrical fire control system. The BDZ-57KRVM bomb carrier is used for the attachment of bombs up to 500kg. Not all vailable munitions are employed at one time, mission dictates weapon configuration. The helicopter carries four UPK-23-250 gun containers with GSh-23L 23mm guns and pivoted mounts (eight units). The forward and aft hemispheres are protected by PKT machine-guns with independent power supply and remote control circuits.
The helicopter may be provided with longrange communication equipment and a radar, and it can carry equipment with phased-array antennas for suppression of enemy electronic attack and air defence facilities, such as airborne radars, air defence (artillery) weapons control radars, surveillance and target detection radars and missile radar homing heads. The ECM equipment can work both in the reconnaissance and ECM modes or in the reconnaissance mode.
The United States purchased a total of 63 Mi-17V-5 military transport helicopters from Russia for use by the Afghan National Army. The overall contracts for the 63 Mi-17V-5 helicopters are estimated to be worth around $1.3 billion. The first contract for the supplies of 21 helicopters was signed between Rosoboronexport and the US government in May 2011 and has been completed. In 2013 Russia completed the deliveries of 12 Mi-17V-5 military transport helicopters under a 2012 option.
Rosoboronexport signed another contract for the delivery of 30 additional helicopters in 2013. US defense officials requested Congressional funds for 2014 "to provide additional enhancements for the Afghan National Security Forces". The 15 Russian-built Mi-17s were slated to be purchased by the Pentagon for $345 million and then given to Afghan national security forces.
The United States scrapped plans to purchase additional helicopters from state-run Russian arms exporter Rosoboronexport amid pressure from federal lawmakers over Russian arms deliveries to Syria, a top US senator said 13 November 2013. “I applaud the [US] Defense Department’s decision to cancel its plan to buy 15 additional Mi-17 helicopters from Rosoboronexport,” US Sen. John Cornyn said in statement. Cornyn, a Republican from Texas, has been leading a push in Congress to oppose the Pentagon’s purchase of Russian helicopters for deployment in Afghanistan due to Moscow’s weapons shipments to the government of Syrian President Bashar Assad as his forces battle rebel groups in a fierce civil war.
The next batch of nine Russian Mi-17V-5 military transport helicopters under a contract with the United States is ready to be delivered to the Afghan army, the head of the Rosoboronexport delegation at the HeliRussia 2014 expo said 21 May 2014. “As of April 2014, a total of 12 helicopters and equipment have been supplied to Afghanistan, and work has been done to build and receive another nine helicopters at various stages,” Vladislav Kuzmichev said. Russia had delivered a total of 45 Mi-17V-5 military transport helicopters to Afghanistan.
