3. Unmanned Air Vehicle Origins
Necessity, the “mother of invention” produced flying bomb concepts during the FirstWorld
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.
Fairey Queen IIIF Mark IIIB, 1932
4. 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.

6. 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

8. 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
9. Global Hawk HAE UAV
High 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
