By far the major uses of unmanned aerial vehicles (UAV) is military, both for reconnaissance as well as certain instances of attack. There is also a growing civilian usage developing for such tasks as fire fighting, traffic control, pipeline surveillance and similar tasks for them as well.

UAVs have come a long way from the model aircraft with radio controls that were their obvious predecessor as nowadays they carry many sophisticated devices for their control s well as their manifold scouting surveillance as well as periodically their attack missions.

During 2005 over 100,000 flying hours were clocked by UAVs in missions over Iraq and Afghanistan. With the advances in technology more and more abilities Are being attached to them. Usually controlled by a remote operator who may be in theater but may just as well be in a control room within the Pentagon a modern UAV is not a toy.

As the capabilities grow for all types of UAV, research and development continues developing further advances enabling them to perform a multitude of missions. UAV no longer only perform intelligence, surveillance, and reconnaissance missions, although this still remains their predominant type. Their roles have expanded to areas including electronic attack, strike missions, suppression and/or destruction of enemy air defense, network node or communications relay, combat search and rescue, and derivations of these themes. These UAV range in cost from a few thousand dollars to tens of millions of dollars, and the aircraft used in these systems range in size from a Micro Air Vehicle (MAV) weighing less than one pound to large aircraft weighing over 40,000 pounds.

The UAV Design team at Cohagan Engineering Inc. has the capacity to utilize the latest advances and incorporate them into the newest and most sophisticated aircraft imaginable. Consider the fact that the vehicle is unmanned but will hopefully fly it's mission and be recovered, serviced and refueled to be ready to fly another mission.

The various elements that are required for each new aircraft are taken into account. First consideration is the mission and thus the payload and the range. A Predator UAV for example has similar features to a normal aircraft in that it has wings and a tail to act as a stabilizer. It is not small having a wingspan of almost 49 feet and a length of 27 foot It is however very different in other aspects. For a start, although propeller powered the propeller is at the tail.

The design experts who put together the Predator were thinking out the box so that they could use conventional aerodynamics combined with the need for the propeller to be out of the way of the cameras, avionics and weapons.

CAD Engineering have the skills expertise and experience to design, develop and engineer a UAV for whatever mission profile is desired., be it for a combat mission or for high altitude suveillance.
