The Royal Australian Navy has a new squadron - and a new weapon in its arsenal - wih the induction of 808 Squadron, and the MRH 90 Multi-Role Helicopter. An induction ceremony has been held at the Naval Air Station at Nowra, in southern NSW, HMAS Albatross. In announcing the new aircraft the Defence department said that the new helicopter will be used by both the Royal Australian Navy and the Army after its induction into the Australian Defence Force Fleet. Chief of the Defence Force, General David Hurley, Chief of Navy, Vice Admiral Ray Griggs, Commander of the Australian Fleet, Rear Admiral Tim Barrett, Commander of the Fleet Air Arm, Commodore Vincenzo Di Pietro, Commanding Officer of 808 Squadron Commander, Charles Stephenson, and current and former 808 Squadron personnel and their families attended the commissioning. Further trials will be conducted with the aircraft after commissioning. In a statement, Rear Admiral Tim Barrett said that the Navy would use the aircraft for the maritime support role previously carried out by the now retired Sea King helicopter, while the Army would use it to replace its Blackhawk helicopters as a battlefield and special operations support helicopter. 'The commissioning of 808 Squadron is a significant milestone for the Navy as we formally welcome into service a new generation, maritime support helicopter that not only replaces the retired Sea Kings, but delivers new capabilities and a capacity to meet emerging requirements in the future,' Rear Admiral Barrett said in the statement. '808 Squadron was previously commissioned into the RAN during the 1950s when it operated fighter aircraft from the Navy's aircraft carriers HMA Ships Sydney and Melbourne. 'The re-commissioned 808 Squadron not only inherits its predecessor's crest, battle honours and motto Strength in Unity, but also its legacy of operational excellence, courage under fire and of breaking new ground in naval aviation. 'This is a significant day for the men and women of 808 Squadron, who have all worked hard over a long period preparing ourselves, our unit and our aircraft to join the Fleet,' Rear Admiral Barrett said. 'Bringing a technologically advanced, new generation aircraft into service is no simple task, but 808 Squadron personnel have worked tirelessly together, and with the Defence Materiel Organisation project office and the Army to reach this milestone. 'There are several nations around the world introducing variants of the MRH 90 Helicopter but 808 Squadron is leading the world in the level of capability being achieved with this new aircraft, particularly in its operations at sea. '808 Squadron is continuing the legacy of excellence of its predecessors and I am pleased to be present today to pay tribute to their service.' 808 Squadron will be based at NAAS Nowra and its aircraft will operate from the Navy's amphibious and afloat support ships such as HMA Ships Success, Tobruk and Choules This post has been edited by Dave Masterson on Jul 11 2013, 05:19 PM Attached Image

Australia commissions helicopter carrier Canberra 02 Dec 2014 Andrew McLaughlin

QUOTE

"The Royal Australian Navy commissioned its first of two Canberra-class landing helicopter dock (LHD) vessels at a ceremony in Sydney on 28 November.

HMASCanberraand her sister ship – to be christened HMAS Adelaide late next year – will be the largest vessels ever operated by the navy. They are based on the Strategic Projection Ship design from Navantia, an example of which is in service with the Spanish navy as theKing Juan Carlos I.

Each LHD has a displacement of 27,500t at full load, and can accommodate 18 NH Industries MRH90 Taipan, Sikorsky MH-60R Seahawk or Airbus Helicopters Tiger armed reconnaissance helicopters, up to 110 armoured vehicles, four amphibious landing craft inside a well dock with sea door and a battalion of up to 1,200 troops. The 230m (757ft)-long design has a 1,390m2 (15,000ft2) hangar/light vehicle deck and a 1,860m2 heavy vehicle deck.The ship also has sufficient generating capacity to be able to export electricity into the power grid of a small city that may have been affected by a natural disaster.

The flightdeck has six landing spots for medium-sized helicopters, or four for the larger Boeing CH-47F Chinook – seven of which will be delivered to the Australian army from next year. Aircraft elevators are located forward and aft, while there is also a forward armaments elevator.

The Spanish design retains its ski-jump ramp, ostensibly because there was no benefit in redesigning the ships without one.However, its retention not only offers cross-decking opportunities for allied fixed-wing types such as the Boeing AV-8B Harrier II or Lockheed Martin F-35B, but also flexibility for the Australian Defence Force to operate such aircraft in the future. The possible acquisition of the F-35B is currently being studied as part of a new defence White Paper due for release in mid-2015.

HMAS Canberra is due to commence first-of-class sea trials before the end of December, during which time the first aircraft will be embarked aboard the vessel to explore and expand flight envelopes from and around the ship, initially using only two of its deck landing spots.

Maurice Farman MF.11 Shorthorn (CFS) Group: Members Posts: 5 Member No.: 5,691 Joined: 30-May 11	The red thingy would be an airflow sensor support. With the new ship they will have to check the rotor wash turbulence at the various landing spots. That big island will make the breeze do some funky eddies over the flight deck. Good luck with the trials.

Turbulence studies for smoother Navy air operations

QUOTE

"Ensuring that helicopters can safely take off and land on Australia’s Landing Helicopter Dock (LHD) vessels is vital to the operation of these major Defence assets.

The LHD vessels, planned to enter service with the Australian Defence Force between 2013 and 2015, are being acquired to increase Australia’s capabilities for amphibious deployment and sustainment in support of land force operations. The LHD hulls are being built by Navantia in Spain with BAE Systems building the superstructures to be fitted later in Australia.

A primary function of the LHD Canberra class vessel will be to mount helicopter operations. The LHD flight deck design allows for six medium-lift helicopter landing spots or four heavy-lift helicopter landing spots on the port side of the flight deck.

The safe operations of these aircraft, including crew safety during the helicopter launch and recovery, greatly depend upon a rigorous understanding of the prevailing airflow above the flight deck and the effect of the sea on ship motion.

“Airflow over any flight deck is generally complex and turbulent due to interactions between the ship’s hull and superstructure and the surrounding air mass,” explains DSTO researcher Stefano Wahono.

“The air wake typically contains regions of large-scale turbulent vortices, akin to those in cyclones. These vortices, invisible to the naked eye, can pose a hazard during helicopter take-off, approach and landing if their effects on aircraft flight are not anticipated by the pilot, so knowledge of their presence and behaviours is essential.”

Turbulence research In 2005, DSTO began work on analysing the LHD flight deck airflow field in order to identify potential hazards for ship-helicopter operations.

The initial work involved combined computational fluid dynamics (CFD) simulations with water tunnel flow visualisation studies. This was to ascertain whether the presence of a ‘ski jump’ aircraft launch platform to be constructed at the bow would adversely affect helicopter operations from the two foremost landing spots.

The scope of analysis, however, was limited to wind angles between plus and minus 30 degrees of the vessel’s heading – winds coming off the port bow and starboard bow respectively. This limitation was imposed by the specific nature of the work program, which was carried out to investigate the expectation that turbulence from the aircraft launch platform would only affect helicopter operations up to those angles.

In 2010, DSTO began another study on the LHD flight deck air wake, this time looking at the turbulence effects on all landing spots for winds from all angles. A CFD approach was chosen for this research because it enabled studies to be carried out on the effects of winds from all angles, offered greater scope for flow visualisation and provided higher resolution data outputs.

The CFD simulations were undertaken at 30 degree increments of the 360 degree compass. Smaller angle variations of plus and minus 7.5 degrees were also studied to investigate the sensitivity of air wake conditions to small variations in ship heading.

Wind tunnel validation To establish whether the computer-based CFD simulation work produced accurate results, a series of wind-tunnel experiments were conducted in DSTO’s Low Speed Wind Tunnel using a 1 to 100-scale wooden model of the LHD, 2.3 metres in length.

The work involved the application of a flow visualisation technique known as particle image velocimetry. This is a study method whereby the air flow is seeded with small tracer particles which, when illuminated, reveal air flow behavioural patterns.

The scope of wind tunnel experiments was limited by the size of the scale model and the width of the wind tunnel test section. Nevertheless, the outcomes obtained served to validate the CFD simulation results.

Study outcomes The CFD simulation work delivered a complete three-dimensional data set of the unsteady airflow around the flight deck for a wide range of prevailing wind angles relative to the ship heading. From this data, velocity and vorticity maps have been derived, and it has also been used to create animations showing how the airflow behaves under certain conditions over time.

The DSTO report produced on the work has delivered detailed findings on airflow structures in the vicinity of all six helicopter landing spots on the LHD. These included airflow quality and turbulence characteristics over a range of relative wind angle conditions for each landing spot, and the potential hazards associated with each spot.

A finding of note was that winds coming from starboard would generally result in more turbulent flow over the flight deck compared to those from port. The higher turbulence levels arising from starboard winds were seen to be due largely to the fact that the ship’s superstructure is on the starboard side.

Meanwhile, a wide range of other wind angles were also shown to be potentially hazardous for helicopter operations if not properly compensated for by pilots.

The simulation results and analyses will be used to support the development of shiphelicopter operating limits (SHOLs) by Navy.

These limits are typically developed and established through the conduct of a series of Navy sea trials known as first of class flight trials (FOCFTs).

The simulated turbulent air wake data may also be incorporated into DSTO’s helicopter flight modelling environment, which could assist Navy planning of FOCFTs by providing findings about the controllability of aircraft in turbulent air. This incorporation of data would also deliver a more realistic flight simulation environment for training of LHD helicopter pilots."

QUOTE

"...Canberra started her First of Class Flight Trials and conducted her first launch and recovery of a helicopter at sea.

Commodore Surface Force Commodore Lee Goddard took the opportunity to visit Canberra in Jervis Bay and said it was exciting to see so many Navy assets working to achieve their required outcomes.

“Standing on the bridge of Canberra it was great to see Jervis Bay so busy with military units working hard to achieve the tasks set before them,” Commodore Goddard said.

“Watching helicopters operating from Canberra’s deck was particularly satisfying.

“At one point Canberra was conducting helicopter operations while launching and recovering her landing craft from the stern door – you could really see the start of the capability coming together,” he said.

Canberra departed Jervis Bay to conduct hot weather trials off the coast of Townsville before she will proceed south in April for cold weather flight trials off Tasmania.

Commanding Officer HMAS Canberra Captain Jonathan Sadleir said that the program was progressing well.

“We are working with the Aircraft Maintenance and Flight Trials Unit to provide the conditions they need to set operating limits for the six spot flight deck,” Captain Sadleir said.

“These limits will be used for the life of both Canberra and HMAS Adelaide to ensure various types of helicopters can launch and recover on the flight deck safely."

Canberra has two MRH-90 helicopters from 808 Squadron and one S70B-2 Seahawk helicopter from 816 Squadron and their flight and support personnel embarked for the trials.

“This process has also tested the ship’s ability to embark aircraft and associated personnel along with their equipment for the first time, and while there have been some challenges, the squadrons and the ship continue to work well together to ensure positive outcomes as the trials progress,” said Captain Sadleir.

After the hot and cold weather trials, Canberra will return to Fleet Base East, Sydney, in May before commencing her work up at sea across all her capabilities."

NHI works to address 'blade flap' rotor head issue 03 Jul 2015 Dominic Perry

QUOTE

“NH Industries is working to deliver a solution to an issue with the main rotor head on NH90 military helicopters that means the blades can impact the tail structure when starting or stopping the rotors during high winds.

Although the problem emerged in the media over the past week following tests with Australia’s MRH90 Taipan fleet, this phenomenon has also been experienced by other operators.

The NH90, in common with other rotorcraft, is fitted with stops on the rotor hub which prevent excessive blade flapping during low-RPM operations.

As the disc spins up, centrifugal force causes the stops to automatically move to a position allowing the blades to move freely for flight.

However, it appears that in some conditions, the stops remain jammed in their initial position at rotor start and are consequently damaged by the vertical movement of the blades.

NHI says although the instances of damage are a problem, “they don't by themselves represent an immediate airworthiness issue”.

Australia’s defence department says that its MRH90s have twice experienced the problem, which resulted in “main rotor head damage”. In both cases the rotorcraft were embarked on Royal Australian Navy vessels – the HMAS Success in 2014 and in March this year during flight trials aboard the service’s new helicopter landing dock, HMAS Canberra.

“The second incident resulted in minor aircraft damage, which is currently under investigation,” it says, while noting that the 11t-class MRH90 continues to operate from other navy ships.

NHI says it is “redesigning the upper stops” with the modification currently due to be introduced during 2017, although it hopes to accelerate the process.

It adds: “NHI is supporting the operators to try to define a limited operational envelope allowing reasonably secured rotor start and stop.

“We are striving to define a more robust preventive measures to limit the occurrences as much as practicable.”

It additionally recommends inspections of the upper stops and main rotor head before the first flight of the day.

NHI is a three-way consortium comprising AgustaWestland, Airbus Helicopters and Fokker.”

Perhaps this will reflect the increase of the needs of the two Cantabria class AOR vessels that are to be commissioned, since unlike HMAS Sirius, both have hangers for their vertrep Helios. Wonder who wears the attrition if a few go out of service, by either service, meaning does the establishment of 808Sqn reduces at a point when the numbers get below a certain Army inventory figure? Kiowas where in the same boat, but there were plenty of those.
