WARR Cryosphere Frigate Rocket Engine Test

Video Caption: This is the first test of the upgraded version of the “Frigate” hybrid rocket engine, conducted on 2016-05-29. Using a star shaped fuel grain with a 3D-printed geometry, the engines thrust was increased by about 1000 N. During its burn time of 5 s, the engine smoothly burned over 1.3 kg of solid HTPB fuel.
The test confirmed the predicted engine characteristics and thereby validated our performance models.
We will soon test the engine again, to confirm our results.

Subscale Engine “Frigate”:
Propellant: HTPB + LOX
Thrust: 1550 N
