Re: Altitude Records Online

Launch on 6th may went well, got a D12-5 to about 1500 ft, and also lost the dam rocket.
Now rebuilding the same rocket, and going for the E30-7, and F72 record with onboard altimeter. Will post with results.

Re: Altitude Records Online

Thanks for that information, nice way to tweek a rocket. I added some weight to the nose cone where the payload is (in the open rocket), and the altitude did increase by 10 to 15%. I did however notice the speed decreased. I have done several simulations with various motors and found some will go up...

AV-1 test rocket

The AV-1 is 425mm long and is able to use engines/altitudes (calculated) as follows: D12-7 at 500m mach 0.5 F30-9 at 990m mach 0.9 F72-10 at 1100m mach 1.23 Will post some end product pics as soon as I can get them. I am using a fin design that is a little different, and this will see if the openroc...

Hello WA

After many years away from rocket/spacecraft designs, I am doing it again. Having got a couple of Estes kits, have managed to construct a test rocket (which would be a re-usable shuttle) on the upper stage of a larger multi stage rocket. Looking forward to the upcoming launch dates, not sure about t...

Re: Altitude Records Online

I will start a thread for the said rocket project with engines and altitude calculations. I did a quick calculation with an F39-9 and the rocket should get to almost 3000ft with almost mach 1, have to wait until a launch.

Re: Altitude Records Online

I have to fit in the smallest alitimeter, that will fit into a 24mm nose cone. This is what I have found http://www.adeptrocketry.com/A1cart.htm" onclick="window.open(this.href);return false; the A1E. Not sure if this is the smallest. Coupled with a video should have all the info for an upcoming rec...

Re: Altitude Records Online

Some of those records could be broken, looking at a D12-5/7 and F39-9, and F72-10. Speeds range from mach 0.5, 0.96 and 1.32 respective according to calculations. Should look at launch in a few weeks to confirm this.
