Project Sparrow | DLX-150A 'Firebolt' Liquid Rocket Engine Test 4 High-speed

In April, Project Sparrow conducted a successful hot fire of DARE's first functional liquid bipropellant engine - a prototype version of the DLX-150 Firebolt. The LOx-ethanol engine sustained a stable thrust of 11kN at a chamber pressure of 40 bar.
This video shows a slow-mo recording of the test, captured using a custom-built camera that can record at framerates of up to 1000 fps. The high-speed footage in the middle of the screen is supported by a synchronized 240 fps recording played in the background.
