I have launched the 17 feb rocket with three solid fuel engines in the desert on 1-4-2012, the day was beautiful sunny and temp. was 19 c .
I do not have sensors for speed and altitude,or parashut electronic release system
the size of the motor was 30 centemeter long aluminum tube by 7 centemetr dia. was made 1000 meter during 2.5 second on flat land.
i add three motors of this type on my rocket and according to my calculation it should make
three times the distance.
launch stared ,i was 20 meters far from rocket with my camera. i did not expect the speed of it when lifted off, in moments disappeared in the sky. my camera caught nothing more then launch start,
i kept listening in the desert silence trying to hear it ,and that what was the result .
after launch rocket and sound disappeared for 6 seconds then i heard sound in the sky like the roar of aircraft for about 3 seconds ,sound disappeared again for few seconds and i saw it falling to the ground 1000 meter far from launching point. the total time from start to back was 20 seconds.
my calculation was rong and it was new experience to me.
next i will try to make simple parashut air release.
