What would it look like if you photographed a rocket engine in super slow motion?
The Slow Mo Guys, a YouTube channel that posts many videos shot using high-performance high-speed cameras, has now released a video of the injection scene of a 'rocket engine' in slow motion.
This time, The Slow Mo Guys witnessed a combustion test of the 'Reaver' engine conducted by Firefly Aerospace , an American private aerospace company.
Combustion testing uses a lot of resources and cannot be repeated multiple times. This is a one-time photo opportunity. It seems that The Slow Mo Guys spent a long time adjusting the camera position.
It protects the lens from intense heat and vibration in close proximity and covers the cables coming out of the back of the camera.
Video that was actually shot. At the beginning, something like a white cloud is blowing out, but this is one of the two propellants. The propellant used is
The flame that blows out next is green, but this is due to the flame color reaction of ``triethylaluminum-triethylborane (TEA-TEB)'' used as an igniter.
A flame ignites. The combustion temperature is extremely high, close to 3040 degrees Celsius.
At the beginning of combustion, the trajectory of the flame coming out of the nozzle was visible, but it soon began to burn violently. The smoke is moving so fast that you don't even realize it's playing at 1/80th the actual speed.
The Slow Mo Guys said, ``I was excited to see the combustion test up close.''
