16 Thousand feet thermals 44 Degrees 02/01/15

The day was not as predictable as conventional analysis would suggest. Many of the forecast models showd different and contradictory data. In the end Q did form in the northern parts of Victoria. The day was slow to get going but Craig V and Peter Temple still managed 1000 klm flights. Assisted by a 20 knot tail wind as convection was only going to approx 3000 ft. Peters flight should enable a claim of 4 records. This is the 4th one thousand plus flight out of Waikerie in the last 2 weeks.

Peter Paine achieved a good flight of 660 klm my flight was also resonable at 582 klm. We headed across the border to Hattah Carwarp and back towards Clare.

Good flight in the LS4 yesterday 582 kilometres at 108kph…

End of a very successful Coaching week and now we are gearing up for the Nationals follow us on facebook.

Trailer Fitting

On Friday 23rd October, John Ridge towed the AS K21 trailer to Waikerie to allow the glider to be fitted. No work was possible that weekend, with a large influx of visitors for “Everything Aeronautical”. Twenty six aircraft flew in – many just for the day and 50 stayed on for dinner on Saturday evening.

Last weekend, (31st October) was a normal flying weekend. Gliding conditions were reasonable, but it took a long time to warm up – so a late start. Pete Siddal flew the Tug, Bradley McKay had 3 flights in the ’21, Dion Baker had his annual check-flight, while other Club pilots explored the lift in climbs to around 10,000 Ft. Towards the end of the day, Pete Siddal swapped saddles and flew the ’21 and Greg Jackson flew the Tug – thanks Greg. While the flying continued, Aiden and Nigel Baker took the opportunity to use a mechanical “lift” to fix the problems with the hangar doors – both the eastern and western ends. It’s now a dream to open/close the doors – a huge thankyou to Aiden and Nigel, well done.

After dinner on Saturday evening, Peter Robinson presented an informative session on Low Level Finishes, which particularly focussed on the high workload which is created when this is undertaken.

On Sunday 1 November, a small band of members gathered to “fit” the AS K21 into the trailer. The ’21 was derigged and the wings “fitted”, allowing the wing dollies to be tested and measurements taken for the permanent installation of the fittings before the fuselage was “fitted”. It is necessary to complete all of the fitting which involves welding before the skin is attached. The “skin” will be white colour bond sheet, fixed to the trailer with 3M “very high bond tape” (effectively a double sided tape. A big thankyou to John Ridge, Peter Paine, Art Hohmann, Craig Vinall and Nigel Baker who persisted for several hours to complete the job. The trailer was then towed back to John Ridge’s place – where the build will be completed.

Another great effort on the weekend by Craig Vinall, who mowed the 02/20 strip and most of the 08/26 strip. Great effort.

AS W20 Tri-Jet

On Saturday morning 15th August, I had the opportunity to experience for the first time the AS W20 “Tri-jet”. With full fuel and the glider DI’d, Allen towed KYA to the threshold of Rny 02. While conditions were not ideal, with a north-westerly breeze – and a slight cross-wind, we prepared for take-off. Each engine was started in order, the wing walker removed and the throttle wound up to 100%. A quick check to see that each engine was producing max thrust and we were away.

The rudder is noticeably very effective very early, so steering is not an issue. Flaps were set to the first stage of reflex to get the flaps working in combination with the ailerons for good control to keep the wings level. At around 40 Kts, I reset the Flaps to zero, resulting in the glider becoming airborne. The glider accelerated to 50 Kts – still with no inclination to climb – similarly to 60 Kts – 70 Kts – and we were away, with the vario full-scaled at 10 kts. The air was fairly turbulent due to the effect of the wind, which was considerably stronger than on the ground. I climbed to around 500 Ft before turning left to fly downwind, endeavouring to maintain a steady speed to allow the Collibri to record the various parameters. I had a play with airspeed and climb rate – up to 90 Kts with no apparent improvement, then progressively back to 60 Kts in 10 Kts increments, which saw the climb rate progressively reduce. It was apparent the ram air effect had a considerable effect on engine performance. Now approaching 2500 Ft, I executed a number of steep skidding turns, with no effect on the engines, before shutting down number 1 and 3 engines. As the engine exhaust temperature reduced towards 80 degrees, these engines were retracted. I then had a play with Number 2 engine, changing the throttle setting down and back up, some steep turns in both directions, slipping and skidding turns before I shutdown this engine, having climbed to a little over 2700 Ft.

The engine noise is by no means uncomfortable in the cockpit – most of the noise disappears behind. With ear plugs, I could comfortably hear the radio above the engine and airflow noise, without having to have the volume wound up. The effectiveness of the rudder once the engine power is increased resulted in some over-correction initially. Ergonomically, Allen has the engine controls well laid out – I had no trouble reaching or adjusting the various items. The engine display is easy to read and select, and the few engine controls (which are necessary to adjust) set up to be very intuitive. With the engines shut down, the 20 was the same as it always was, extremely nice to fly, even in the turbulence.

After a flight lasting a total of 26 minutes, I landed back on Runway 02, well satisfied with my first flight in the AS W20 “Tri-jet”. Now looking forward to some more flights in the “20.

Working Bee

Thanks to those who attended the Working Bee on Saturday – Greg Jackson, Mark Morgan, Peter Paine, Ron Brock, Graham Francis, Allen Hudson, Grant Hudson, Craig Vinall, Bill Mudge, David Lawley, Tony Edge and Mark Mortimer.

Several important jobs were completed – David Lawley tidied up the wiring to the Data Projector and Wireless Access point, Greg laid half the carpet in one of the Dormitories, Allen Hudson put a new jack on the Pie-Cart, Graham Francis repaired some doors, Mark worked on the water points for the National comps, bill Mudge tidied the main hangar, Pete Paine tidied the Igloo and filled some holes in the main hangar floor and Ron Brock sprayed the weeds.

A few beers and a meal prepared by Grant topped off a good day’s work.

Performance Week Update

Wednesday 31 December 2008

Performance week has been a huge success. We have had very good weather; not hot 10,000ft days, but good 5,000 ft cu days with not more than 30 C max with close spaced reliable lift. There have been no days cancelled and all but one or two aircraft have been around each day’s task.

There is certainly a very positive atmosphere; people are learning a lot and having a good time as well. There are more than 50 people hear and over 25 gliders. The event is getting more popular each year.

Today, I had a great coaching flight with Ingo Renner. We flew in the club ASK21. In fact I think it was not only its first extended cross country flight but we also launched the glider by winch; its first winch flight in Australia. By the way, I think this glider will be excellent for cross country training. On the right day, it will be an easy glider for novice cross country pilots to fly and will be the equal of any other two seater for training purposes.

The day was blue with thermals going to 5-6,000 ft. Not only did we get around without any trouble at all, but it seemed so effortless mainly due to Ingo’s amazing thermal centering ability. It was simply a master class for me and will greatly help me. I look forward to trying to pass on some of what he taught me.

It’s New Year’s eve and the party is in full swing. We’ve already had to buy in more red wine! It will be a great evening with a few sore heads in the morning…

The weather forecast looks to be only improving for next week and so I’m looking forward to the State Comps. Hope to see you here.

Happy New Year.
