Eurocopter EC725/H225M

1436963211-1-o

The Eurocopter (now Airbus Helicopters) EC725 Caracal (also named Super Cougar) is a long-range tactical transport helicopter developed from the Super Puma/Cougar family for military use. It is a twin-engined aircraft and can carry up to 29 seated troops along with two crew, depending on customer configuration. The helicopter is marketed for troop transport, casualty evacuation, and combat search and rescue duties, and is similar to the civilian EC225.

The EC725 is based on the Eurocopter AS 532 Cougar, improving upon the design with a five-blade composite main rotor incorporating a new airfoil shape to reduce vibration levels. The helicopter can be fitted with removable armour plating to protect the troops and is powered by two Turbomeca Makila 1A4 turboshaft engines mounted over the cabin, which feature a dual-channel Full Authority Digital Engine Control (FADEC) system. They can be fitted with an anti-icing system to enable the aircraft to operate in very cold climates. Other improvements include a reinforced main rotor gearbox and an all glass cockpit. The cockpit is equipped with an integrated display system featuring a digital map and Active Matrix Liquid Crystal Displays

The helicopter has day and night time search and rescue capabilities by way of a search radar and Forward Looking Infra Red (FLIR); these allow the EC725 to be flown under visual meteorological and instrument flight rules conditions. The EC725 can be equipped with various military equipment and armaments, such as a pair of 7.62 mm FN MAG machine guns mounted within forward left and right windows, or a pair of 68 mm (2.75″) Thales Brandt or Forges de Zeebrugge side-mounted rocket launchers, each with 19 rockets, or the MU90 Impact aerial-launched torpedo. Brazilian EC725s are equipped with a Helibras-built countermeasures suite, which includes chaff and flares to confuse radar and heat-guided missiles respectively; Thales has also produced self-protection systems to equip French EC725s.

The EC725/H225M, AS332, and AS532 Gun Mount Assembly attaches to the standard floor hard points with no structural aircraft modifications required. Installation is designed for left and right door applications while still allowing easy access through the doorway. The system incorporates a kick-out arm assembly to fire, then stows when not in use allowing the doors to close. The ammunition for the M134D is supplied by a 3,000-round ammunition magazine and feed system.

Features:

  • Total field of fire approximately 110° (Left and right azimuths based on aircraft configuration)
  • Elevation 1.5° Depression 55°
  • 24 VDC battery
  • Integrated battery status indicator
  • Integrated stow/lock of the gun in azimuth and elevation
  • Gas assist stowage of arm (reduces the amount of weight the operator has to pull into the aircraft)

Weight:

  • Total system weight loaded with 3,000 rounds approximately 430 lb (195 kg)

Dimensions:

  • Base plate 22.56” (57.3 cm) X 48.97” (124.4 cm)

Aircraft Interface:

  • Pilot control box
  • 24 VDC trickle charge

MU90/IMPACT advanced lightweight anti-submarine torpedo

The MU90/IMPACT is an advanced lightweight anti-submarine torpedo used by navies of Germany, France, Italy, Denmark, Australia and Poland. It is designed to compete with and outperform the US-built Mark 46 in the anti-submarine role, and is also available in a special MU90 Hard Kill version for anti-torpedo defence. The MU90 is built by a wide consortium of European companies organised as EuroTorp.

The MU90 was the result of separate projects in France and Italy from the 1980s. In France, a project under the direction of Thomson Sintra created the “Murène” in 1989, while in Italy Whitehead started work on an A244 replacement known as the A290. In 1990 the first attempts to merge the two efforts started, a process that was completed in 1993 with the formation of EuroTorp.

Among its many features, the MU90 is capable against any current or perceived threat, including a bottomed stationary mini-submarine, known versions of anechoic coatings, and various decoys. It is also capable of launch speeds up to 400 knots, allowing it to be dropped from maritime patrol aircraft flying at high speeds, or rocket-assist launchers. Powered by an electric pump-jet, it can be run at “silent” speeds to avoid giving its location away to the submarine, or “dash” at speeds over 50 km/h. It uses a shaped charge warhead that can penetrate any known submarine hull, especially Soviet double hull designs, while remaining just as deadly in shallow waters where conventional warheads are less effective.  Source bluebird-electric.net

Eurocopter developed four primacy cabin configurations for the type. The Troop Transport version contains a seating arrangement for a maximum of 29 troops, in addition to the crew. A dedicated VIP transport version is designed to contain between 8 to 12 passengers. The Casualty Evacuation version can carry up to 12 stretchers along with a total of four seated medical staff. The Combat SAR configuration is fully equipped to perform search and rescue duties in a combat environment.

Makila 2A / 2B

Launched at the end of the 90s, the Makila 2A features a new, higher-performing compressor module as well as dual-channel Full Authority Digital Engine Control (FADEC). The Makila 2A powers the EC225 and H225M Caracal helicopters manufactured by Airbus Helicopters.

The Makila 2A is fourteen per cent more powerful than the 1A. It delivers a take-off power of 2,101 shp and a cruising power of 1,970 shp. Maximum power using the One Engine Inoperative (OEI) rating is 2,415 shp. Time Between Overhaul (TBO) is 3,500 hours. It was certified in 2004.

In 2014, Safran Helicopter Engines launched the Makila 2B, a revision of the 2A, intended for the H225 helicopter manufactured by Airbus Helicopters. The 2B has a new combustion chamber and new high-pressure turbine blades for increased take-off performance and, in particular, payload. The Makila 2B underwent initial flight testing in 2014 and progress in ongoing. Source safran-helicopter-engines.com
