Rocket ignition is always impressive, but it’s not the easiest to see with the naked eye, for very obvious reasons. It cannot approach the combustion temperature, and its brightness is generally blinding.Thanks to the popularity YouTuber’s high speed video But the curious can take a look at recent test ignitions to see how complex, beautiful, and perhaps terrifying ignition works.
The new video is slow mo guys, a team of expert videographers…well, we can connect the dots. YouTubers were given a front row seat at one of the following test firings: firefly aerospaceWe used the Reaver engine, but unlike previous tours, this project required quite a bit of upfront planning. First, rockets traditionally consume a lot of fuel and resources, so The Slow Mo Guys only had one chance at him. For example, each SpaceX Falcon9 rocket uses tens of thousands of gallons of kerosene and liquid oxygen.
Even this one attempt required positioning, rigging, and timing to begin shooting at a sufficient distance without injuring anyone or property. According to Slow Mo Guy Gav Free, this special enclosure can withstand the intense heat and vibration needed to house a slow-motion camera, while also adjusting the equipment to handle the brightness of the explosion. It also has the ability to In the end, Free and his colleagues settled on exposing the film 40% darker than he normally would to account for brightness.
Judging by the footage, all that preparatory work definitely paid off. At 2,000 frames per second (80 times slower than real time), viewers may be surprised to see the first bright green flame. It is produced as a rocket fuel mixture. Triethylaluminum-triethylborane (TEA-TEB) will burn on contact with oxygen and air. After the initial green burst, yellow and orange flames appear, but the frame rate is so slow that you can actually see them. Them The flame is generated in response to the shock wave generated by the thrust of the engine. The rocket engine can generate more than 45,000 pounds of thrust in a vacuum at temperatures as high as 5,500 degrees Fahrenheit, Free said.
