The discussion revolves around the challenges and considerations of launching a rocket from a high altitude weather balloon, specifically focusing on the ignition of the rocket engine at altitudes around 70 km or higher. The participants explore potential solutions to ensure successful ignition despite low oxygen levels.
Participants generally agree on the potential effectiveness of using solid fuel and integrating the igniter with the fuel compound, but there is ongoing exploration of the best methods to achieve this.
The discussion does not resolve the specific technical details of the ignition process or the design of the combustion chamber, leaving some assumptions and dependencies on definitions unaddressed.
Individuals interested in rocketry, high-altitude launches, and ignition systems may find this discussion relevant.
How would I integrate this into the igniter?JBA said:If this is a solid fuel rocket then use the rocket fuel compound as a part of the igniter and there should not be a problem because the sufficient energy from a spark or heat from a wire coil is all that should be required.
So basically embed the igniter coil directly into the engine of solid based fuel closest to the exhaust nozzle?JBA said:For example, use a small high resistance wire coil embedded into a small molded slug of the fuel compound or the bottom of the solid fuel at the exhaust nozzle.
