This write-up of the core burner test is condensed as it is very similar to the test performed with the hybrid finocyl \/ core burner test<\/a>. On Friday 21st<\/sup> of February the KILO core burner motor was static tested on a 66\/12 reload. This was motor was designed for maximum volumetric loading, lowest core mass flux thus reducing erosive burning at start-up and followed by an expected progressive thrust curve.<\/p>\n

Upgraded igniter consisted of a 4gr CuO\/Fe03\/Mg thermite 10mm heat shrink tube igniter inserted in a 20mm heat shrink tubing with mix of 6gr thermite and 8gr of plain APCP shavings sealed with some toilet paper rolled up into a ball.<\/span><\/p>\n

Chamber pressure and thrust was again independently measured. After days of rain, the weather was dry and partial sunny at 9\u00b0C. After a 5sec count down the remote controlled ignition was pushed, the igniter popped the thermite charge and after 6 seconds the motor came up to full pressure. Thrust profile showed an expected and acceptable erosive spike at start up followed by a progressive burn and 3-4s tail off. Basically the thrust curve is all over the place but a good sustainer motor. The motor reached a total impulse of 16.780Ns at a Isp of 215s. This motor delivered 6.300Ns or approximately 60% more total impulse than the previous KILO 5GXL sustainer motor which flew in the GIGA III.<\/p>\n

For now,this test concludes the development for the GIGA IV sustainer motor which is now flight ready.<\/p>\n
