CRGs' June 2018 HPR Launch at Ardlethan

Postby Voyager » Mon May 28, 2018 11:11 am

Canberra Rocketry Groups 2nd high power launch for 2018 will take place on the weekend of the 23rd and 24th of June at our Ardlethan launch site, weather permitting.

The High Power launch site has a ceiling of 15,000 feet and is located in wide open paddocks with few trees. We will also be launching low and mid power rockets.

All rocketeers are welcome to come along and fly to their certification level. Launching will kick off about 8:30 each morning and will wrap up about 5pm on the Saturday and 1pm on Sunday. If you would like to come along, let us know through either a message on Facebook or through email to canberrarocketry@ozemail.com.au

CRG has the launch equipment to launch low, mid power rockets on rods and high power rockets on 1010 rail (up to 3 metres long) and 1515 rail (3.6 meters) on a reinforced frame. We have hybrid launch capability, but rocketeers are more than welcome to bring along their own launch kit if they need something that we do not have. Contact us via our email address and we can discuss if our kit fits your system.

Interstate flyers interested in launching with us at Ardlethan are most welcome and should contact us for further details by emailing canberrarocketry@ozemail.com.au

Ardlethan is about 3 ½ hours from Canberra, 4 ½ hours from Sydney and about 5 hours from Melbourne. Head to the CRG website (http://canberrarocketry.no-ip.org/) and go to the High Power page for more details on the site. Click on the following link for a Google maps link showing the location of Ardlethan – http://goo.gl/maps/z3jXW.

Accommodation in Ardlethan is at the London Hotel with both motel style and pub rooms available. To book accommodation give Jason a call on 02 6978 2300.There is also a B&B operated by Del Garett that people can stay at – Del can be contacted on 0457 905 005. Accommodation is also available at the Beckom Hotel a few km from Ardlethan.

Hope to see you at Ardlethan.

Cheers

A slightly depleted group (Tony and Josh both had work commitments) experienced perfect conditions for this HPR launch weekend at Ardlethan. The mornings were a little frosty, but clear skies and almost no wind for two days, and no fire risk due to recent rains.

Highlights of the weekend included an L1 certification for Marcus, and two flights to over 12,000’ for Warren. This broke the CRG altitude record by over 3,500’. We will soon be pushing up to our 15,000’ foot ceiling. Might need to increase that!

We are all looking forward to our September launch.

Congrats on the good day and flights.

If you get GPS locations for launch and landing (and record an altitude as well) of each flight you can do some statistical analysis on that and prove to CASA or Air Services what your expected cylinder you need will be if you request a higher ceiling. We had clearance to 35k' at Serpentine, but the cylinder was made ridiculously big by the authorities because they didn't think a small cylinder appropriate. We pared ours back to 25k' just to stop interfering with other airspace users in the region. If you give them data they may be more sensible when you apply.

Thanks guys! Thanks for the airspace tips too, OTT. We'll need to look into this because we will soon run out of upper limit. We currently share the airspace we do have with Rex Aviation. They have a regular Sydney-Griffith-Sydney service that directly over-flies our launch site. We have a standing agreement with them and factor them into our daily launch schedule.

Video from the last Ardlethan weekend of some of the high power launches, taken from the launch tower, can be seen on our Youtube channel.

1st video is Nev's upgraded HP Big Daddy.
2nd video is Warren's Tomach on its way to 12,000+.
3rd video is Mark's 2-stage Double Shot.

Would you have considered using simulations, as well as actual flight data, to determine the operating radius for your cylinder. We have access to a few software tools that provide drift analysis with multi-level winds. It's not as good as real data, but you achieve a statistical analysis over different conditions more easily. You would need quite a few real flights to achieve confidence in you statistical analysis. Perhaps a combination of the two methods?

I guess it really depends upon what CASA and/or Air Services considers appropriate.

Scatter simulations are useful (I run them myself for the high flights, with aggressive wind profiles) in a general sense, but hard data can't be argued with. Sims don't usually take into account anomalies such as main deployed at apogee etc. Refer to my signature below :wink:
