Rocket ignitions are generally captivating, but observing them with the naked eye can be difficult for apparent motives. The intense temperatures and blinding brightness make it not possible to be close to them. Luckily, higher-speed video technologies enables curious men and women to witness the intricate, stunning, and potentially frightening procedure of rocket ignition.

The Slow Mo Guys, a well-known YouTube channel specializing in slow-motion videos, lately had the chance to capture a test ignition of Firefly Aerospace’s Reaver engine. As opposed to their prior projects, this endeavor expected comprehensive arranging. With rockets consuming huge amounts of fuel and sources, the group only had a single opportunity to film the ignition. Moreover, they had to very carefully position and rig the camera to make sure the security of everybody involved. An enclosure capable of withstanding the intense heat and vibrations was specially developed to home their slow-motion camera. To manage the brightness of the explosion, the gear had to be calibrated, and the film was intentionally exposed more than 40 % darker than usual.

The meticulous preparation yielded outstanding benefits in the footage. At two,000 frames-per-second, the video showcases an initial vibrant green flame. This happens when a rocket fuel mixture known as triethylaluminium-triethylborane (TEA-TEB) combusts upon get in touch with with oxygen and air. Following the green burst, yellow and orange flames develop into visible. Due to the slow framerate, viewers can witness the flames reacting to the shockwaves generated by the engine thrust. The immense energy of a rocket engine is highlighted, as it can make more than 45,000 lbs of thrust in a vacuum at temperatures reaching as higher as five,500 F.
