[Aus-soaring] Darling Downs weather for the weekend of 10 - 11 March 2012
Hi folks The forecast for the weekend is up at http://the-white-knight-speaks.blogspot.com.au and it looks quite good. Saturday will probably be blue to about 8,000ft while Sunday should see cloudbase of about 8,500ft. I will update tomorrow as usual. -- Robert Hart ha...@interweft.com.au +61 (0)438 385 533 http://www.hart.wattle.id.au ___ Aus-soaring mailing list Aus-soaring@lists.internode.on.net To check or change subscription details, visit: http://lists.internode.on.net/mailman/listinfo/aus-soaring

While down south it's our turn to check for flood damage on our airfields; it's been a tough season all round.

[Aus-soaring] Mars weather for the weekend of 10 - 11March 2012
Thermals on Mars: http://www.abc.net.au/news/2012-03-08/a-whirlwind-rises-from-the-surface -of-mars/3875938 The retrieve might be difficult, the launch even harder. The aircraft would be difficult to fly. The air density at the Martian 'sea level' is the same as FL800 (80,000' AMSL i.e. about 1% of sea level on Earth), so the indicated airspeed is about one tenth of true airspeed. Gravity is about one third of Earth's, so you only need to develop one third of the lift to get airborne, but that would require very high speed in the thin air (I think you need to go close to Mach 1 to get airborne and the stall is not much below Mach 1). Thermalling would be interesting because of wide radius turns (you see the air is so thin that the turning force is correspondingly small). But remember you would still have the inertial mass. Landing would be interesting too, airbrakes, spoilers and parachutes wouldn't work that well because they wouldn't develop enough drag. Your landing speed would be near Mach 1 too, so if you had a prang, you would tumble across the Martian landscape for a fair distance (because the lack of air resistance would slow you down). Your wheel brakes would be less effective because you would only have one third of the weight on the wheels. You may need a cable arrestor system! I have mucked around with flying on Mars in X-Plane (it also has the Mars elevation data), it is very tricky. You need something with a low wing loading and long slender wings (much like a glider!) ___ Aus-soaring mailing list Aus-soaring@lists.internode.on.net To check or change subscription details, visit: http://lists.internode.on.net/mailman/listinfo/aus-soaring

Well, we did have them at Gawler in 2001, and as they are every 2 years, that's not so very far apart for a World Comps On 8/03/2012 12:00 PM, aus-soaring-requ...@lists.internode.on.net wrote: Message: 1 Date: Wed, 7 Mar 2012 11:51:42 + From: Angus Stewartstewa...@gmail.com Subject: Re: [Aus-soaring] World Gliding Championships 2015 To: Mal Brucem...@mals.net, Discussion of issues relating to Soaring in Australia. aus-soaring@lists.internode.on.net Message-ID: cafn5kg9ontjjgxxj3sacmkrtq+tclbba9vrxffz1ngwczwp...@mail.gmail.com Content-Type: text/plain; charset=windows-1252 Woohoo!
