I have been testing igniting Quest micro AP motors. I was able to get successful ignition to 60,000'. One test was to 50,000'. In that test I was able to get ignition and the powder charge even popped. At
60,000' I got ignition but the powder charge did not pop. At 80,000' I got nothing but several burn out ignitors (note: new motors used each time). In all tests I used the Quest micro motor and the Quest igniters. The question is does anyone know how to ignite a composite motor at 80,000' simply? Not being NASA, we don't have the resources to develop complex ignition systems.I have considered using a carbon tube to launch the rocket from instead of an open launch pad as originally planned. The tube would be sealed at one end and a clay inverted bubble placed at the other end. Once the motor built up pressure the rocket would launch through the inverted clay bubble. Does anyone know if this has been tried?
