How Can I Use Compressed Air to Lift a Load of 400lbs?
jezym108 asked:
this is for a school project
i have to find ways to lift a load of 400lbs about 30 feet into the air, without using traditional methods like rotors
i came up with using an air compressor to route compressed air into 4 small rocket nozzles to lift it off the ground
how powerful of an air compressor would i need if i wanted a constant thrust of 500lbs coming out of 4 small nozzles (125lbs out of each nozzle)?
if that is actually possible can the compressor be driven by something like a 50hp engine?
ie. an axial or centrifugal compressor attached directly onto the crank of the engine
also are there any alternatives to lift a 400lb load while having a small footprint on the ground
the only criteria being that the power required to get the load airborne should be less than 100hp

If you have 100 psi air available, you can use a 4 square inch piston to do the job. It would just need to be 30 feet long. Of course if you added some pulleys and went with a bigger piston, you could do it with a shorter piston.
