I am attempting to build a Liquid Fuelled Rocket Engine. You can read about my research and attempts to do this on my blog at http://www.britishreactionresearch.blogspot.co.uk.
I would be very interested to hear from anyone else, particularly in the United Kingdom, who is working along similar lines. There are many such projects in the US and around the world, but as far as I know mine is the only British one.
Many thanks,
Carl.
