About Stofiel Aerospace



What Defines Us

Stofiel Aerospace is a team of diverse professionals passionate about providing simplified, cost effective, dedicated access to space for all. Located in St. Louis, Missouri, we find inspiration in our region’s long legacy of being a launch point for adventure and established history of space exploration.

How We Work

We live by the “fail fast, fail often” method of development. We believe that this method is good science AND good business. Utilizing the manufacturing capabilities of extrusion 3D printing, we are able to drive production times down to days instead of months. The use of low cost materials and manufacturing combined with state of the art engineering and technologies give our customers unique launch capabilities that beat our competition by 25%

  • MK1: February 2016

    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.

  • Bella R1: Mar 27, 2016

    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.

  • MK2: March 2016–July 2016

    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.

  • Bella R2: Jul 9, 2016

    Balloon carried a small rocket to an altitude above 100,000 feet. Rocket failed to launch due to a stress relief problem. Two balloons gave us a higher altitude and longer drift before landing.

  • 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 +4000℃.

  • MK3: Mar 2017–Now

    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.

    Generation 6 heat coating is surviving 2200℃ through burnout.
