Launching a UAV

    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 thats used as the gas??

    I m totally at sea....

    How fast does the UAV need to be going to fly and how much thrust does it have?

    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 isnt 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?

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