The AgustaWestland EH101 is a medium-lift helicopter originally developed as a joint venture between Westland Helicopters in the UK and Agusta in Italy for military applications but also marketed for civil use.

Development

In 1977, the UK Ministry of Defence issued a requirement for a new anti-submarine warfare (ASW) helicopter to replace the Royal Navy's Westland Sea Kings. Westland responded with a design called the WG.34 that was approved for development. Meanwhile, the Marina Militare (Italian Navy) was also seeking a replacement for its (Agusta-built) Sea Kings, leading Agusta to a series of discussions with Westland about the possibility of a joint development. This culminated in the joint venture being finalised in November 1979 and a new company (EH Industries) being formed to manage the project the following year. EH is an abbreviation for Elicottero Helicopter, incorporating both the English and Italian words for "helicopter." As the design studies progressed, EH became aware of a broader market for an aircraft with the same broad capabilities required by the British and Italian navies, leading to a more generalised design that could be customised for specific customers and applications. After a lengthy development, the first prototype flew on October 9 1987. EH Industries no longer exists, having been incorporated into the parent when the two companies merged.

Design

The military version of the EH101 is powered by either three Rolls-Royce Turbomeca RTM322 turboshafts (UK, Canada, Japan, Denmark and Portugal), or three 1,491 kW General Electric CT7-6 turboshafts (Italy). Engine inlet particle separator systems provide protection when operating in sandy environments. Each engine is supplied by a separate self-sealing fuel tank using dual booster pumps. Each tank holds 1,074 litres of fuel. A fourth tank acts as a reservoir supply, topping up the main tanks during flight. A fifth transfer tank can be added to increase range, as can airborne refuelling. The engines power a 18.59 metre diameter five bladed main rotor. The rotor blades are constructed from carbon/glass with nomex honeycomb and rohacell foam, edged with titanium alloy. Computer control of the engines allows the EH101 to hover reliably in winds of over 80 km/h.

The modular aluminium-lithium fuselage structure is damage and crash resistant, with multiple primary and secondary load paths. Active vibration control of the structural response (ACSR) uses a vibration-cancelling technique to reduce the stress on the airframe. The EH101 is rated to operate in temperatures ranging from -40 to +50 degrees C. High flotation tyres permit operation from soft or rough terrain.

The cockpit is fitted with armoured seats for the crew, and can withstand an impact velocity of over 10 m/s. Dual flight controls are provided, though the EH-101 can be flown by a single person. The pilot's instrument displays include six full colour high-definition screens and an optional mission display. A digital map and Forward Looking Infrared system display can also be installed.

Weapons

A chin turret can be fitted with a 12.7mm machine gun. The stub wings have hardpoints for rocket pods. The EH101 is equipped with chaff and flare dispensers, directed infrared countermeasures, infrared jammers, missile approach warners, and a laser detection and warning system. The HM Mk1 model can carry 4 Sting Ray torpedoes or Mk 11 Mod 3 depth bombs, or the Sea Skua missile.

Cargo Systems

The military version EH101 can accommodate 30 seated or 45 standing combat troops and their equipment. Alternative loads include a medical team and 16 stretchers, cargo pallets. The cabin floor and rear ramp are fitted with flush tie-down points, a roller conveyer for palleted freight and a cargo winch. The ramp can take a 3,050 kg load, allowing it to carry vehicles such as Land Rovers. An cargo hook under the fuselage can carry external loads of 5,440 kg. A rescue hoist and a hover trim controller are fitted at the cargo door.

Avionics

The navigation system includes a GPS and inertial navigation system, VHF Omnidirectional Radio range (VOR) instrument landing system (ILS), tactical air navigation (TACAN) and automatic direction finding. The EH101 is equipped with helicopter management, avionics and mission systems linked by two 1553B multiplex databuses. A Smiths Industries OMI SEP 20 automatic flight control system provides dual redundant digital control, giving autostabilisation and four-axis auto-pilot operation.

dobar heli kojeg su sa skupnim snagama napravili Italjani pod nazivom Agusta te Britanci pod nazivom GKN Westland tako je i dobio ime AgustaWestland........hm ali zanimljivo pri ovom je to šta je za vojsku ovaj heli poljetio 1987 godine a za civilnu uporabu tek 1997......hm  a ovu verziju civilnu imaju "Tokyo Metropolitan Police".......

a to bi bio ovaj.....

nije los heli , juce sam gledao emisju o njemu pa sam zato stavio temu o njemu

takodje

ma nelazi...

najozbiljnije pre 20 dana na exproreru

a je pre dva dana na national geografic

glup kanal po meni

To su inace Britanski helihopteri koji su sluzili za sve zemljane Americke akcije u Bagdadu.

sto bas je jak inace on je vise rangiran na zapadu i od Explorera i od Discavery chanel
