Braumer tailpipe

Post by multispool » Thu Jan 19, 2006 11:12 pm

Hi Chaps,

First an intro, I used to be on Keneth's newsletter mailing list some years back, mostly curiosity as my first interest was/is gas turbines but felt I needed to find out if I've been missing out so decided to build a "Sugden special" diesel engine and a Braumer Pulse jet,

Anyway, my question is I have made the tail pipe from some available s/s tubing 20.87mm ID instead of 20mm. Seeing that it's a tuned pipe do I need to shorten it to mantain the same internal volume? This would mean shortening from 370mm to 351mm length.
Comments etc!
