Heat Transfer Revisited – BRR

Carl from Brittish Reaction Research has posted a new update on his rocket engine project and is looking for some guidance on his heat transfer calculations.

This post is going to deal with some tentative calculations on the quantity of heat transferred through the walls of a rocket nozzle I am building. This study is part of my ongoing engine project. To be more specific, I’m interested in finding out how much coolant flow will be required to safely absorb the heat generated by the combustion gases.

Carl runs through the series of calculations required in detail which can be found here, worth a read, it is really easy to follow and if you can help him out, do so!

If you have got this far, thank you for staying with it. Perhaps now you would allow me one last indulgence and tell me if you think I have got it somewhere near right!

Help out a fellow amateur rocket engineer!

Launch of Skybolt 2

The rocket was restricted to 4000ft altitude but looks like it all went off without a hitch. Not sure about successful chute deployment, the slow-mo video appears to show the chute shred from the fin can stage.

The Guardian also did a nice article which can be found here.
