Capitalism in space: The rocket engine startup Rocket Crafters experienced what the company called “an anomaly” during an engine test yesterday, requiring the local fire department to put out brush fires surrounding the test site.
The company is trying to use 3D printing to build its engines, but appears to have had a string of engine failures, none quite so spectacular, during previous tests.
According to an earlier post about Rocket Crafters in 2018, they had hoped to launch a rocket in 2020. It does not appear they will. Moreover, they are testing the use of hybrid fuels in a somewhat radical design.
[T]he rocket fuel consisted of plastic tubes made from the same base materials as Legos, measuring two feet long and weighing about five pounds, that were stacked on shelves and safe to touch. Combined with nitrous oxide — commonly known as “laughing gas” — the small-scale test engine on Monday generated about 200 pounds of thrust firing at half-power.
They are not the first to try hybrids and have issues. Virgin Galactic has tried it to, and suffered probably a decade delay in development and a spaceship that does not have as much thrust as they would like.
