Mi-35M (Hind E) Attack Helicopters

The Mi-35M is a multi-role combat helicopter manufactured by Rostvertol, a subsidiary of Russian Helicopters. It is an export variant of Mi-24 Hind attack helicopter. Primarily designed for attack and military transport missions, the helicopter delivers superior flight performance and manoeuvrability than its predecessor.

The production of Mi-35M started in 2005. The aircraft integrates modern, high-precision weaponry for destroying ground-based armoured targets and providing air support for ground missions. It can be modified as an attack, ground assault, medical evacuation (MEDEVAC) or transport platform.

The Mi-35M is one of the modern combat helicopters in the Russian Air Force inventory. It is also operated by the armed forces of Venezuela, Brazil and Azerbaijan.

Mi-35M orders and deliveries

Venezuela signed two contracts with Rosoboronexport in 2005, for a total of eight Mi-35M helicopters. The helicopters that were delivered to Venezuela were fitted with VK-2500 engines for high-altitude operations.

The Brazilian Air Force formally inducted three Mi-35M helicopters into service in April 2010. The helicopters in FAB service are referred to as AH-2 Sabre. A total of nine helicopters were delivered by August 2012. The final helicopter was delivered in December 2014.

Azerbaijan signed a contract with Rosoboronexport for the delivery of 24 Mi-35M helicopters in September 2010. A total of 12 helicopters were delivered by 2012. The last batch of helicopters was delivered in November 2013.

The Iraqi Ministry of Defence received the first batch of four Mi-35M helicopters in November 2013. The second batch of four was delivered in July 2014 and the third batch in October 2014.

Nigeria placed a contract for six Mi-35M combat helicopters in August 2014.

Excerpt

The first deliveries of Russia’s combat helicopters Mil Mi-35M (NATO reporting name: Hind-E) to Kazakhstan are scheduled for the end of the current year, Alexander Shcherbinin, deputy chief executive for business development at Russian Helicopters holding, the helicopter manufacturer, said on Wednesday.

“The first deliveries of this helicopter (Mi-35M) through the Rosoboronexport (Russia’s arms exporter) is scheduled for the end of this year”, Shcherbinin said, without specifying the details.

Russian Helicopters Produce Two Mi-35M for Mali: Here

Excerpt

Russian Helicopters holding company produced two Mi-35M transport/attack helicopter for Mali under Rosoboronexport-related contract. Aircraft and all property necessary for their operation is delivered to the customer.

“Performance of the contract on Mi-35M delivery to our Mali partners once again confirms that the holding company holds a leading position in the world market of attack helicopters. I am sure that successful implementation of this order will result in growing demand for Russian helicopters in the region,” said Russian Helicopters CEO Andrey Boginsky.

“I am confident that the helicopters we delivered will help Mali to protect its sovereignty and fight against the universal threat of terrorism. I also would like to mention that the supply of Russian Mi-35M helicopters is another significant contribution to the development of military and technical cooperation between our two countries, which in recent years has demonstrated a good upward trend,” said Rosoboronexport CEO Alexander Mikheyev.

The new Primus HF 1050 System is superior to other HF systems in many ways. Among many other features, it allows for the separation of the Power Amplifier and Antenna Coupler. This feature allows the antenna coupler to be located closer to the antenna, improving the effective radiated power of this 200-watt PEP high frequency system.

Key Features of the New Primus HF 1050 System:

Radio Features

• HF1050 system is hard mounted; no shock mounts required eliminating 1.5 inches installation height and up to 5 inches in sway space restriction
• Stored coupler tuning in non-volatile memory…once tuned always tuned.
• High fidelity audio data input and data output for interface to external modems. 246 International Telecommunications Union (ITU) maritime radiotelephone network channels stored in permanent, non-volatile memory.
• 280,000 discrete operating frequencies covering the 2.0000 to 29.9999 MHz frequency range.
• SELCAL® compatible audio output to an external SELCAL® decoder alerting the pilot of an incoming voice call

‘S-13’ type 122mm unguided aircraft rocket

5 unguided rocket options

S-13OF: The only 122mm rocket available, this large rocket packs a blast-fragmentation warhead with some serious wallop, dealing significant damage to soft targets and lightly armored vehicles, and can even destroy a main battle tank with a direct hit. With only 5 rockets per pod, accurate delivery is key.

The S-13OF

S-8KOM: Designed for defeating armor, this rocket has a dual-purpose warhead that can penetrate up to 400 mm (15.75 inches) of armor in addition to generating enough fragmentation to perform well against soft targets.

The S-8KOM

S-8OFP2: The S-8OFP2, also called the S-8M, is a modernized version of the S-8KOM with a greater effective range and increased fragmentation effect for better effect on soft targets.

The S-8OFP2

S-8OM: The S-8OM rocket dispenses a parachute-carried flare about 20 seconds after launch that emits a retina-searing 2 million candles* of light for about 30 seconds. The flares only dispense while the rocket is in the air and will extinguish on contact with the ground.

The S-8OM

S-8TsM: This rocket creates a plume of orange smoke wherever it lands that can be seen at great distances, making it a great tool for an airborne forward air controller.

Earlier, engines were produced only in Ukraine, the spokeswoman added.

“No less than 200 various versions designed for helicopters and planes are planned to be manufactured before 2020. Earlier, engines for our civil and military aircraft were manufactured only in Ukraine,” the spokeswoman said.

“Now, the TV7-117V engine is made of only domestically-made units and components,” she added.

According to Denisova, the baseline TV7-117V engine is among the world’s best motors in terms of its efficiency, reliability and service life.

The TV7-117V engine “can switch to emergency modes of 2,800-3,750 hp to ensure flight safety in emergencies”, she added.

The engine’s turboprop versions can be mounted on the Ilyushin Il-114 and Il-112V planes.

“We are planning to produce more than 200 turboshaft and turboprop versions of the TV7-117V engine before 2020,” Denisova said.

According to the spokeswoman, the corporation is currently organizing the full-scale production of the engine. Source airrecognition.com
