Static Fire for Q3 75km Mission is a Success

Our recent Static Fire was a success, learn more about the test and our next move towards a 75k launch mission.

Watch the full test here.

Today, we are excited to announce that we recently completed a successful static fire test. The test served as a dress rehearsal for our upcoming 75km subscale mission in Q3, and validated several new technologies we’ve had under development in the process:

  • A high-current, static-safe, Federal Range-compliant ignition module

  • Proprietary high-volume loading, neutral-burning grain geometry lowering vehicle’s time in pitch-roll inflection and enabling significant erosive burning advantages at takeoff

  • New high-density, high-solids loading, very low-burn rate propellant designed to enable new geometry

  • New Aramid-based, centrifuge-cast liner

  • New carbon-phenolic composite nozzle

We’re calling the test an 8/10 success, which we’ll absolutely take for all the new technologies being tested together for the first time. The 275-lb motor produced 13,000 (!) pounds of thrust at ignition before leveling off to a dead-neutral 8200lbs for 8 seconds.

For reference, our mission will have an initial thrust: weight ratio of 37:1. Our last mission was roughly 4:1, causing the vehicle to linger in pitch-roll inflection for far too long.

The highly erosive geometry did its job, but did a number on the low-margin composite nozzle - resulting in a perfectly symmetrical burn-through of the divergent portion six seconds in. This is easily corrected through the addition of more ablative material. Residual mold release agent in the grain port from the manufacturing process briefly inhibited the ignition; we will continue to work to correct this.

This static fire test was our first big test since rebranding to Evolution Space in May, when we also moved our manufacturing facility to the Rockford, Illinois area. The success brings us one step closer to enabling nanosat developers of all shapes and sizes to more readily access space.

We will move forward with launching an 8-foot subscale rocket on a mission to 75km in late September in Black Rock City, Nevada. We’ll keep you posted on our progress towards the launch on Instagram, Twitter, and Facebook. So make sure to follow us there!
