Last April, we caught wind of a very impressive rocket engine being built by Copenhagen Suborbitals. That engine was on the test pad this weekend, and the video is incredible (skip to 20:30 for the actual test). The Copenhagen Suborbitals team pulled off a successful test firing of their 65 kilo Newton alcohol and liquid Oxygen-fueled rocket.
When last we saw the TM65 engine, it was sitting on the design floor of the Copenhagen Suborbitals workspace. The plan was to fire the engine using alcohol fuel and LOX pressurized by Helium, but that plan was changed to use Nitrogen as the pressurant. The static test was an immensely successful demonstration of the engine, but unfortunately the chamber pressure (and therefore thrust) was a little low meaning the team will be moving back to Helium for the next test.
Thanks to the very successful test of the TM65, Copenhagen Suborbitals may be launching their HEAT booster later this year possibly carrying their new space capsule. Even if it’s only a crash test dummy that will make the ride into space, we can’t wait for the video of the flight.
Check out a few more (abridged) videos of the TM65 test firing after the break.
