UNMANNED AERIAL DRONES
History Military Use Civilian Use Public Fears
Matt Burns, Cory Dressler, Katie Eakins, Ally Zimmer, Alyssa Clevenger, Patrick Blood
Unmanned Air Vehicle OriginsNecessity, the “mother of invention” produced flying bomb concepts during the First World War. The armistice halted experiments on all but targets.
1917: French artillery officer, Rene`Lorin proposed flying bombs using gyroscopic and barometric stabilization and control.
1918: Germany halts development of guided weapons.
1918: Charles Kettering (USA) flies Liberty Eagle “Kettering Bug” and Army Air Corps orders 75 copies.
1920: Elmer Sperry perfects the gyroscope and the first enabling technology makes flight control feasible
1932: RAE “Fairey Queen” crashes, technology is still in its infancy.

UNMANNED AERIAL VEHICLES
MILITARY USES• Attacking targets
remotely without risking American lives.
• Constant surveillance of enemy targets.
• Near-instant strikes on targets of opportunity.
• Air support for ground troops and allied forces.
Design of UAV Systems
Introduction to UAVs
1990s - Reusable launchers Design of UAV Systems

Example - Manned airspaceDesign of UAV Systems
Introduction to UAVs
All countries have rules for how aircraft must operate in their airspace. • Most follow guidelines developed by the International Civil Aviation Organization (ICAO)• Rules apply to two types of airspace
- Enroute airspace - the airways - Terminal airspace - around airports
Airspace rules are based on manned aircraft experience
• The established system is complex and slow to change
Pilots, not ground controllers, have primary responsibility for safe operation/separation of aircraft
• UAVs have ground (?) controllers not pilots UAVs will have to fit into a pilot based system
Example - Base operationsDesign of UAV Systems

QuestionDesign of UAV Systems
Introduction to UAVs
What do these challenges have to do with us (Aerospace Engineers)?
• UAVs are air vehicles, they fly like airplanes and operate in an airplane environment
- They are designed like air vehicles- They have to meet flight critical air vehicle requirements
- Aerospace engineers understand the environment, the requirements and the design challenges
• We know how to integrate complex, multi-disciplinary systems
We provide leadership in development of air vehicle systems- UAVs are simply our next air vehicle system challenge
Global Hawk HAE UAVHigh Altitude Endurance Unmanned Aerial Reconnaissance System
Mission Provide continuous day /
night, high altitude, all weather surveillance and reconnaissance in direct support of allied ground and air forces across the spectrum of conflict
Increase the reach of existing and future surveillance systems
Extraordinary range and endurance
Fewer number of systems required to maintain global ISR coverage
