I have read and been told, a good engineer can tell a lot about how the rocket engine is running by just looking at the exhaust.
Scott Manley goes into some good detail on why rocket engine exhausts look the way they do.
Video Caption: Why does the exhaust from the Space shuttle boosters & engines look completely different? There’s a huge variety in the appearance of rocket exhausts because different fuels, different technologies and different environments make them behave in a different manner.
I have previously posted about Scott Manley’s informative videos explaining more in depth information about rockets for Kerbel Space Program players. Looking into the physics and more engineering design, these videos are a good watch for anyone wanting to get to know rockets more.
This week Scott talks about rocket engine plumbing and engine cycles.
Robert Watzlavick has posted a new update on his work of his liquid-fuelled rocket.
The update includes,
– CAD work on the rocket
– Pressurization and burst disks
– Getting rid of NPT fittings
