Below is a quick representation of the head-end-ignition setup as used on the GIGA III rocket. There are many different configurations which work, including a more integrated, pyrotechnic, flame thrower type solution. However for the sake of robustness and proven designs I remained close to the modified NERO style M10x1 head end igniter body and the LD
On February 3rd we had a nice day of testing with blue skies, little wind and 6° Celsius. Two motors were to be tested both with the goal of having high thrust and short burns so they could be used as a booster for the forthcoming 2 stage rocket. The first motor made by LD
Since my rocket activities in the summer are low – I get distracted due to the other fun stuff – it turns out I do a lot of the APCP mixing in the winter My workshop for mixing doesn’t have permanent heating, is poorly isolated anyway and temperatures regularly drop to 5-10°C. At these temperature the HTPB and thus the propellant
On Friday 19h October we tested a smaller KILO 3G motor with a simulated total impulse of approximately 5.000Ns. The famous Alumaflame propellant formula was modified by removing the AP to make it pourable but maintaining the same CuO/Al percentages. This 3G motor was designed to be a full L or baby M1650 with a 3s burn suitable
On September 20th, LD and JVDB static tested a joint monolithic motor project. JVDB provided the design, foam cores & motor hardware. LD developed the grain casting process, assembled the motor and provided the test stand. This motor was our first try at a monolithic grain motor with a complex foam core. We believe case bonded, monolithic grains are a
On 20.09.2018 we tested 3 motors of which the monolithic moonburner was my own and a monolithic finned core / star grain was a joint venture with LD. The moonburner burn was succesful and the thrust curve spot on according to Bursim simulations. At the end of the burn there seems some off-center thrust. Upon post firing inspection it
