Air Compressed Compressed air Gas Psi Thrust

Click For Summary

To lift approximately 200 pounds to a height of 300 feet using compressed air, significant pressure is required, specifically around 160 atmospheres for a cylinder of 6 inches in diameter and 1.5 feet long. The discussion highlights that compressed air is not an efficient energy source, as it cools upon expansion, limiting its thrust capabilities. Alternative propulsion methods, such as electric motors or hydrogen peroxide, are suggested as potentially more effective solutions. The feasibility of the project is questioned, emphasizing that the current setup may not provide enough thrust for the desired height and weight. Ultimately, the design may need to be re-evaluated to incorporate a more suitable propulsion system.

Exactly what I had in mind, but I couldn't find a high enough torque motor that won't be too big. And thanks, but I just need the math is all. Also my line will be steel cord.

Try checking out the "Superheroes" episode of Mythbusters (or maybe the Star Wars one, I forget) if you can find it on U-Tube or the Discovery Channel site. Jamie managed to build a wrist-mounted winch for his grappler that pulled him up fairly smartly, and that dude has got to be well over 200 lbs.
