ASK 't Harde, 3 September, 2004 - As usual the launch campaign took place on two days: the Thursday, when we prepare the launch site and rockets and the Friday, when we launch the rockets. On Thursday the launch tower and the new upright motor test stand were quickly erected. Preparing the rockets took some more time, because two flyers arrived to late. All but Bert Koerts' Payloader, which was missing his motor casing, were ready in time for launch on Friday. The Thursday ended with a good meal and great evening at the mess.
Friday morning started with breakfast and some last preparations. The first launch was the Shock and Awe of Leon Krancher and Mark Uitendaal. Their two-stage rocket is powered by two potassium nitrate and sorbitol motors they developed themselves. The rocket had a good lift off. The first stage was dropped at an altitude of 170m and the second stage reached an altitude of 420m. When the rocket parachuted the nose cone broke from the rocket, but all parts landed undamaged. The stage separation was better than its first launch at NLD19.
Next was the level 1 certification flight of Tripoli The Netherlands member Ramon Peeters with his Amraam 2. The rocket had a good flight on an AeroTech H128-W and Ramon Peeters got his level 1. Later, when looking at the pictures, it was discovered the rocket left the tower at a considerable angle, fortunately away from the public. This was probably due to the relatively large top fins of the Amraam 2 design.
After the crash of the N24 16 months earlier no N-rocket had flown. This summer the old N8 (1993) was rebuild and mated in the N25 with a Kalinitrox K600 motor, which was held in storage for eight years. Like the N8 rotation was also measured. The launch was perfect, in fact one of the best I have ever seen. The N25 reached 1260m and it rotated around its vertical axis in 1.8 seconds.
The next launch was the Jan-Hein Ramakers' Sonic Boom with one of his Basterd motors. Unfortunately this launch became a failed motor test, as the motor produced only smoke and no thrust. The last HPR launch was Bert Koerts' Bullpup, which had a nice flight. The launches ended with two big model rockets of Michael Fach, which both flew well.
This was followed by NAVRO motor test CMT0409. In the new upright NAVRO motor test stand the new Kalinitrox motor was tested. This motor has another mixture of Kalinitrox and uses Bates grains instead of an hollow tube/slotted tube combination. Unfortunately the pressure inside the motor became to high and the safety mechanism was activated. It seemed at the time the motor has acted as an hollow tube motor, probably because the top and bottom sides of the grains were not completely flat. Apart from two failed motors it was a very good launch.
