First rocket fired with a PLA 3D printed Hermes thrust system in place. Used off the shelf G79-10W aerotech motor. Generation 1 heat coating.
Balloon carried a small rocket to an altitude of about 80,000 feet where the rocket launched. Traveled 54 miles down range. Established that the fuel mixture we anticipated using would fire in the low oxygen environment.
Fired 16 iterations of this rocket system. Adjusted geometry within 24 hours of previous firing. Generation 2-5 heat coating was finished, survived 1200℃ through full stress cycle.
Balloon carried a small rocket to an altitude above 100,000 feet. Two balloons gave us a higher altitude and longer drift before landing.
Generation 8 Heat Coating
Developed a proprietary composite heat coating and application process. The proprietary heat coating allows PLA plastic, that normally melts at 200C, to survive a composite rocket operational cycle and withstand +3000℃ and upwards of 10,000 psi. Patents pending.
Fired over 9 rockets to date. Currently firing at a rate of one thrust system per week. Four different geometries were tested for main observations.
Fired 2 MK4 rockets, with more to follow. This iteration is to develop geometries for proper thrust capabilities. ISP numbers are consistently increasing.
