Launching a UAV...

Hey guys...

Can someone help me to come up with some ideas on how to launch a UAV...

Is air pressure launching a better idea than bungee launch?

The aircraft weighs around 15 pounds. Is there a better idea?

If its pressure launched...woudnt it be air that's used as the gas??

I m totally at sea...

The drawback to compressed air is that you need something to do the compression. That means either man power to operate a hand pump of somekind and low pressures, or a compressor that can do high pressures.

Depending on how many times you would launch it, you could look into compressed air bottles from an industrial gas supplier. Honeslty the bungee/slingshot is the easiest in terms of set up and lowest complexity.
 
We are looking at a launch speed of around 35 knotts(65km/hr) at about 9g...

And isn't pumpin air an easier job than tyin a bungee some 90 meters away??

i m confused...atleast can u guys provide me some links that'd help me?

thnx!
 
Is this going to be a glider or does it have some sort of on board power supply
