18th March 2018 Launch "Flames Smoke & Noise Spectacular"

Postby Digit » Tue Feb 20, 2018 5:53 pm

LAUNCH INVITATION

The Queensland Rocketry Society Inc (QRS) would like to invite all interested people and members of the Australian rocketry community to our March "Flames, Smoke & Noise" spectacular launch.

After the success of our previous "Flames, Smoke & Noise" launch, we're doing it all again!

This launch will be well promoted so we are expecting a large number of spectators and potentially professional media coverage so bring your biggest*, loudest and most exotic rockets and have some fun showing our hobby off to the public! There will be a sausage sizzle and cold drinks available for purchase, and there will also be toilet facilities onsite for this launch.

Remember to pre-order any larger motors required that Australian Rocketry might not carry in their mobile store!

Just a reminder this is a change to our usual advertised launch in that it has paid entry for non-QRS members.

LAUNCH DETAILS

Date: Sunday 18th March 2018
Range Open: 0800.
Range Closed: 1300.
Ceiling: 5000ft AMSL. (A NOTAM will be posted with Air Services Brisbane office).

DIRECTIONS

If you require directions to launch area 2 at Cedar Grove, please refer to the QRS Website.

SPECIAL NOTICES FOR THE DAY

* Members are asked to sign in at the RSO table at 8:00am.
* If your membership is not current on the day, you will not be able to launch.
* HPR rocketeers will need to provide evidence of a current QLD explosives licence.
* If launching an unproven design, either scratch built or a modified kit, bring a copy of your sim so the RSO can verify the stability/safety of your rocket.

AMRS CERTIFICATION FLIGHTS

This launch is AMRS sanctioned and AMRS certification flights for Level 1 & 2 will be conducted. Remember to make arrangements with the AMRS Certification Officer prior to the launch day. AMRS members from across Australia who wish to attempt certification are welcome to attend for this purpose.

UNFAVOURABLE WEATHER

If adverse weather or other conditions on the day of the launch effect the launch program, the launch will be rescheduled. If on the day of the launch, you are uncertain the launch will proceed, check this post for updates or contact ‪07 33331655‬and follow the prompts to local clubs. A cancellation notice will be posted to the launch site shortly after 7:00am on the day of the launch.

See you there!

*N.B. Due to launch site restrictions, we must still operate within our 5000' ceiling, however you're welcome to use every inch of it and make a lot of noise in doing so! 8)

Excellent!

I want to attempt L2 Certification on the day. Who should I contact (AMRS Certification Officer) regarding arrangements?

Thanks

Joe

p.s. invited a few family members along, with their children. Can they do a "QRS Trial Launch" on the day? (I've packed a few extra junior rockets).

Great you are coming down Joe, your L2 attempt is already taken care of, as I will be overseeing it ;-)

Yes, of course, just get them to sign up as a trial member and they will be good to go.

Great day to pick to certify. Hope you aren’t too distracted.

Looking very closely at the Ceiling of 5000 feet AMSL
I've checked Google earth and it says the LA2 is at 100 feet AMSL, however I've seen 215 in other posts.
I'm currently looking at I297 Skidmark which my most accurate OR sim says will throw the Flying Dutchman up to 4714 feet.
So my margin is either 186 feet or 71 feet :shock:

So I'm now thinking that I'll either add a larger size case and spacer or go to a smaller motor.
However It would be nice if someone could confirm ground level at LA2.

LA2 is 83’ (or maybe 86’) so you should be OK ;-) worst case, move to the creek line which is practically at sea level.

86 feet gives me exactly 200 feet margin. What I did to get a more accurate sim was to reduced drag on my Thunder 2015 simulation till it came into line with the actual performance, then reran the cedar grove simulation which gave me the previously mentioned altitude. Primarily I targeted base drag (reduced to 30%) as historically the faster flights where the less accurate. The coast speed graph came out a lot closer to what the Raven showed so I think I’ve got a pretty close sim. I’ll go over my work again I think and might come up with a plan B just in case.

What are people planning on flying?

I have two flights planned:

1) L1 cert with my SCR Quake "Mk4 Rocket Propelled Companion Pod" - 66.7 mm to 3100ft on an H135
IMG_8495b.jpg

This flight will see me flying two Altimeter 3's - I'm using this flight for relevant scientific testing.. One of my A3's spent a little over two months in the corn field, this will allow me to compare the output from both of them to test the "weathered" one.

2) Another crack at (successfully recovered) supersonic on an 29mm MD "Aspera III" - G80 simmed to Mach 1.2 and 4700ft
* The first attempt (subsonic) on an F39 broke the NC attachment.. NC recovered, airframe turned up 6 week later.
* The second attempt saw a strengthened nose cone attachment method and went supersonic on a G80, but saw the shock cord snap (IMPORTANT LESSON: Kevlar kite string is not the same as kevlar shock cord...) NC and streamer recovered, airframe still out there somewhere...
* With this third attempt, we now have a slightly elongated NC shoulder to make a little more room for the electronics and 3mm Kevlar throughout (it will rip out of the airframe before it snaps).. We're slowly walking the failures down the airframe :P - I have high hopes... As they say: "Third Time's a Charm!"

Good luck with the L1 snrkl :). Looks great!

Looks good snrkl can’t quite make out the writing on the decals. I like the idea of having your checklist written on the rocket, care to share a closeup of the instructions? :D

That is super cool snrkl! Awesome to see a fellow Portal fan!! I never even thought to do a rocket though. Sorry to get sidetracked but here is a full scale (5 feet tall!) light box I built a few years ago. I'm part way through a full scale companion cube too. 8)

Very nice.

I didn't get around to doing decals. I wanted to, but time got in the way.

Anyhow....Plenty of opportunities to get some done in future.

That’s awesome... now I’m wondering where I could hang something like that at my place...
