Aerotech Space Challenge

[ghostfather]

Just came across this....interesting, but I'm not sure if it can be done with only 40,960 N-s

 

[David Schwantz]

I'm on it

 

[DAllen]

Is there a link to this somewhere?

Reminds me of this: Aerotech Million Foot Challenge.
This time, reduced by 100x $$$ and isn't a hoax.

$10K "might" pay for the motors & hardware...

 

[NTP2]

Sub minimum with a second stage?

It’s for fun and glory!

 

[ghostfather]

I'm guessing that it can be done with a 98mm small O booster, and 2nd and 3rd stage 75mm almost full M's, which should get you close to the 40,960 N-s.
They suggest using the O5500X as booster, and two yet to be certified full M 75mm motors.

Personally, I'd go with a full O fast burner and a boosted dart: It's been done before.

Aero Dyne SR110-AD-1 Super Loki solid-fuel rocket; 25 kN (5520 lb) for 2.1 s (OK, that makes it a P)
A 98mm booster, 54mm dart, and a little less Impulse should do it

10k will fund the motors and airframe. Travel costs not as much. O5500 is around $2500. A 75mm full M from CTI is $800. Even if you up it to 5k for motors , you can build a hell of a nice airframe for 5k. Even stepping up to a 6 inch O6000 staging to a K62 your still under all limits.

The catch is that actually hitting this on the first attempt would be absolutely wild.

Darts won’t be allowed, but 2-stage is the ticket. The West Point rocket would have reached 100 km if it had flown substantially vertical. We will release the rules soon.

Guaranteed that the prize will end up being over $10K.

I've been waiting for this to be filled out for quite some time:

hehehe

I won't be one of the contenders for the space challenge, but I probably will be buying the casing and reload when it's released.

I really, REALLY wish I was
1 18+
2 had a L3
3 had money
So I could compete ahhh well

Ps does anyone that is competing need a side kick?

Start your design processes. You can spend hundreds of hours in optimizing and designing different possibilities

What is the point, I can’t compete.

Ps that sounds sadder than I actually am.

What's the point of asking to be a team member on a project if you don't want to contribute? Never stop learning

Sounds like a plan...

That was more of a joke, I don’t have the time.
Ps but 100% agree with statement 2

As someone that reviews 100K projects for Tripoli, I'm thrilled at the increase in the number of applications that will come from this. At least I get to steal a lot of good ideas.

Shucks, Jim

I was thinking you had the best chance at the prize if you could fly your VOS !

I think the VOS, at 2.5 pounds, would weight too much for a class 2 rocket. It can be used on a larger rocket, such as a large P to middle O, but even then there is a pretty good hit on the altitude if the system is on the sustainer. The value of it, in theory, would be to minimize spin and coning.

Link isn't working for me, where else can I find this?

 

[3stoogesrocketry]

100k feet on 40kns is very achievable. The new full M baby N in 75mm will make it alot easier.

98mm M2500 to a 75mm M/N 3xxx with a 10 ish second delay between staging is well above 100k.

Seems the whole RCS rocketmotorparts.com website is down. Whenever it's back up try the link again.
