I spent some time taking stock and organizing the garage workspace a bit this past weekend. Not the most exciting thing, but useful. Theo and I came across some old Estes motors and we decided to do a little impromptu motor test. This motor was a D 12-5.
Here are the manufacturer’s stats on this motor:
Total Impulse: 16.84 newton-seconds
Peak thrust: 29.73 newtons
Burn Time: 1.65 seconds
Average Thrust: 10.21 newtons
The second image in the sequence is the motor under full thrust. The third and fourth images are of the delay charge going off. I drilled some vent holes in the wooden base, but they weren't enough to prevent the motor from ejecting itself from the "test stand", in this case a wooden block. The motor only managed to go a few feet in the air. Theo, "Whoa, we launched it!"
