Hi TRF, recently I went with my former high school to launch 4 rockets on hypertek motors. One of these rockets was going to break the speed of sound. The rocket was a 3" carbon fiber rocket. It took off fast and from there we never saw it again. I am under the assumption that the ejection charges deployed too soon and that the chutes did not come out while it was hauling. The altimeter used was an AIM USB 3.0 with mach inhibits set at 7 seconds.
My assumption is that perhaps 7 seconds was too short, because the motor burns for 5.6 seconds and I pressume it was still going too fast that the altimeter may have been fooled and fired the ejection charges on the way up.
Would like your opinions on this.
Thank you
