RTM322 Engines for EH101 Chopper

The Royal Navy has selected the Rolls-Royce Turbomeca RTM322 engine to power its EH1 0 1 helicopters.

Rolls-Royce Turbomeca has been awarded the contract to supply and support production standard engines for the EH10 1 development program, and also to carry out the RTM322 installation and integration design work. The RTM322 installation design work will commence immediately and the first such engine will be installed in the fourth pre-production aircraft, which is currently flying, as soon as possible. This new engine replaces the General Electric CT? engine as the EH101 powerplant.

The RTM322 is also considered in the running to power the planned NH90 helicopter currently under consideration by France, Germany, Italy and the Netherlands

The prototype US Army MH-47E special operations Chinook has begun its flight test program. The new Chinook version, of which some 50 production models will eventually be acquired by the US Special Operations Command, is the result of a modification program involving existing US Army stocks of the CH-47O. The MH-47E has been designed to undertake Jong range or rapid deployment special operations missions at low level, day or night, in adverse weather conditions and over all types of terrain. It is equipped with forward looking infrared sensors, multimode radar for terrain following and avoidance, twice the fuel capacity of the CH-470, two .50 calibre machine guns if needed, external rescue hoist, and seating for up to 44 troops. Production deliveries are expected to commence in 1992 and run through to 1994

New Westpac Sponsored WA Police Air Wing Ecureuil

There has been much controversy in WA over Westpac Banking Corporation’s withdrawal of sponsorship of the Royal Life Saving Service (RLSS) rescue helicopter operations.

Costs associated with the RLSS sponsorship deal were cited as a major factor in the decision. The RLSS MBB Bo 105 has since been put up for sale with all ex-sponsors’ names removed. The service has effectively ceased operations, leading to claims by some critics that rescue services have suffered.

Meanwhile, Westpac has opted instead to sponsor the WA Police Emergency helicopter service. The initial Police Air Wing equipment was a leased Bell 20 6 Jetranger, though without winch or nightsun search light this did not entirely suited to the task. This aircraft has since been replaced by the Aerospatiale AS355F Ecureuil 2, VH-NJL, an aircraft that is without doubt well suited to the task of search and rescue. It is pictured here resplendent in Police Emergency Air Wing markings, the Westpac ‘W’ clearly visible along with other smaller sponsors of the service

The McDonnell Douglas MD 520N five seat commercial helicopter, which features the NOTAR no tail rotor system, has joined the MD 530N in flight tests. Both aircraft, equipped with the NOTAR system in which pressurised air instead of a tail rotor provides the anti torque and directional control, are expected to receive FA A type certification later this year.
