UAV's

04/01/2012 3:04 PM

The U.S.Army has a UAV in operation called the Raven. It has a wing span of 4'-3", a length of 37" and weighs 4.5 lbs. The cost is $35000 and the entire system which includes electronics goes for 1/4 mil. It can fly to 10000 ft for up to 90 minutes. It is powered by an electric motor and batteries. So much for the particulars. The capabilities of such a device are the dreams of model aircraft enthusiasts. After searching the internet, I haven't found out much in the way of details such as the type of motors and batteries used. The models now available can flyfor maybe 15 minutes at the most and a range of 1/2 mile. The Raven has an 8 mile range.

Does anyone here have better information than what I've found?

Commercial Batteries Power Unmanned Aerial Vehicles . The RQ-11B Raven B that replaced the Dragon Eye uses rechargeable batteries to power its propulsion and other systems. It can stay in the air for 1.5 hours.


The U.S. Army currently uses this battery pack in one of its unmanned aerial vehicles that flies reconnaissance missions in Iraq and Afghanistan. Built of 96 AA-size TLM batteries and rated at 32V/480W, it powers the aircraft's emergency recovery system. Due to its light weight, approximately 2 kg, and considerably smaller size compared to the previously used batteries, this battery pack reduces overall system weight and requires less space inside the aircraft.
