Dordrecht, 12 December, 2004 - Again a motor test for the new Kalinitrox K2000 motor with Bates grain configuration. This motor test is a repeat of the failed motor test CMT0409 at NLD20, when we thought the top and bottom sides of the Bates grains didn't burn and thus the motor acted as a hollow tube motor. We now know by comparing this and the latest results, the pressure inside the motor was much too high.
The top and bottom sides of this motor's grains were better manufactured. The throat was 12mm. This time at 60 bar (6000kPa) the pressure was again to high, so the safety mechanism kicked in again. Fortunately the Bates grains worked this time as planned. After the safety mechanism was activated the motor was still operating at 5 bar (500kPa). This should give us an indication of the size of the nozzle we are looking for.
