AT, yes realize that I need to configure the vessel so that compressed air forces out all the water and a 90deg bend good idea. I need to work out what pressure, nozzle size, volumes required?

No I haven't tried a horizontal bottle rocket but if it develops thrust and I can achieve a reactionary force (pushing against something) then I see no reason why it won't work. Thinking about angling the jets downwards to achieve backward thrust (forward movement) - so my force required...

Horizontal water rocket thrust calculations - HELP! Hi All, I want to accelerate a 90kg body at a rate of 2 m/s2 for a period of 1 second using thrust developed from a number of water bottle rocket jets. Based on the drag coeff calculated I believe I need to develop 190N of force. A...
