Yeah that is all I was going to do. Just take the Cosine of the nozzle trim angle and multiple it by the force. Max thrust would be with an angle of 0 degrees. I think if you played with the angle from 0 to 45 degrees you could get a min and max range of thrust. I was just going to use 45 degrees and then multiply the force by 1.5 for a safety factor. You don't want to spec out a cylinder and it not to be powerful enough to throw the nozzle up! I think I looked at a cylinder with a 4 inch stroke, double action, and a spring return.
All in all, it isn't that complicated. But I was lazy and didn't feel like calculating anything. Key is how much volume of air do you need, and at what pressure. No since and building a system and you only get two times using the nozzle. I liek air over CO2 because it will be cheaper but I imagine the CO2 has higher pressures since it is a liquid in the tank, Who knows. Someone else make one, I will jsut use your system Doug until you make one
