Navy's next helicopter completes trials on HMS Iron Duke
皇冠体育app Royal Navy's next generation helicopter, Wildcat, has completed demanding trials aboard HMS Iron Duke, laying the groundwork for future operations.

Wildcat landed nearly 400 times on the frigate鈥檚 flight deck by day and night in various weather conditions as the ship sailed off the coasts of southern England and northern Scotland.
皇冠体育app Portsmouth-based frigate sought the most challenging weather conditions around the UK as she took the Wildcat - successor to the long-serving Lynx - to sea to help write the rulebook for the new helicopter.
From 2015, Wildcat will be the principal helicopter used by Royal Navy frigates, including Iron Duke and her Type 23 sisters, and destroyers on operations around the globe.
Although Wildcat looks like the final variant of the Lynx Mk8, currently in service with the Fleet Air Arm, it is classed as a new aircraft - it handles differently for a start, not least thanks to new engines and the distinctive tail boom which marks Wildcat out from its forebears.
As a result, a new rulebook has to be written to define what are known as 鈥榮hip-helicopter operating limits鈥� - the guidelines for safe Wildcat operations by day and night in various weather conditions and with different payloads.

For that, Wildcat needed to go to sea. It enjoyed two ten-day periods of trials aboard Iron Duke, one in mid-January, the second at the beginning of this month, ranging from the waters off the South Coast to the Western Approaches, Irish Sea and northern shores of Scotland as the frigate searched for suitable weather conditions to lay down the limits for safe Wildcat operations.
In all, Wildcat touched down on Iron Duke鈥檚 flight deck 390 times, including 148 night landings - 76 of them using night-vision goggles.
From Iron Duke鈥檚 viewpoint, the new helicopter certainly impressed. Commander Nick Cooke-Priest, the frigate鈥檚 Commanding Officer, said:
Wildcat is a very capable aircraft, a completely valued successor to the Lynx, and once fully mature will provide significantly enhanced capability to the maritime domain.
Prototype ZZ402 paid a brief visit to Iron Duke just before Christmas, when pilots and technicians tested some of the basics such as whether the flight deck recovery system could pull Wildcat into the hangar, did Wildcat fit in the hangar, can it be easily refuelled and rearmed and 鈥榯alk鈥� to the frigate鈥檚 command systems, all of which were in the affirmative.
皇冠体育app prototype鈥檚 two Fleet Air Arm test pilots assessed and scored the difficulty and workload required for each landing in each different weather condition or sea state, while a myriad of sensors recorded more than 4,000 different items of data from the helicopter鈥檚 engines, rotor and transmission.
皇冠体育appse included video feeds from all the crew positions, stresses and strains from all over the airframe and rotor blades, engine and gearbox parameters and undercarriage loadings.
皇冠体育app crew scores and reams of data are now being analysed by experts (it鈥檒l take them until towards the end of the year) to set the limits for day and night operations by Wildcat at sea in various conditions and with various payloads.
In addition to the test pilots, two flight test engineers, aircraft and stress engineers, instrumentation experts and ship鈥檚 flight personnel (to carry out maintenance on the prototype and move it in and out of the frigate鈥檚 hangar) - a good 30 extra souls in all - squeezed aboard the Type 23, which was fitted with accurate ship motion and wind sensors for the tests.
皇冠体育app trials team used the opportunity of operating Wildcat at sea for the first time to test its mission systems, night-vision cockpit and navigation systems, paving the way for the helicopter鈥檚 front line duties in three years鈥� time.
Commander Cooke-Priest said that the helicopter is 鈥榠deally suited to the nature and breadth of naval operations鈥�, and added that:
Commanders should be very excited by Wildcat鈥檚 potential.
While Wildcats work their way along the production line at AgustaWestland鈥檚 Yeovil factory, ZZ402 will continue her trials, including tests of radar, electro-optics and navigational kit, and conducting missile firings.
皇冠体育app first of 28 naval variants of Wildcat is due to be delivered to its future home of Royal Naval Air Station Yeovilton ten days before Christmas for trials with 700W Naval Air Squadron.
