What is a Flying car ?

Why do we need flying Car ?

What is special in designing a flying car ?

Design approachRoadable Aircraft

Flying Car

Continued…. Dual Mode Design

Flying Motorcycle

Design considerationsRange

Endurance

Rate of climb

Cruise speed in air

Cruise speed in land

Airworthiness standards

Automobile safety and Emissions

Continued….Acceptable in flight wing aerodynamics while able to

retract , fold or detached and stow the wing for road travel.

Need to rotate on take off.To find engine/transmission which could meet the

conflicting demand of ground and air.Dual mode control systems.Stability and performance requirements in both modes of

travel.

Design conceptsGlenn Curtiss in 1917 exhibited his design of flying

automobile in Pan- American Aeronautic exposition in New York.

Waldo waterman was the first person to be granted a patent on roadable aircraft “Arrowbile” in 1937.

Continued…..Robert E. Fulton in 1946 designed a new concept his

FA-3-101 Airphibian

Convair Air car in 1947

Continued…. Moulton Taylor designed and built “Taylor Aerocar” in

1949

Avionics Glass panel; the proof-of-concept airplane includes: Dynon Avionics  EFIS-D100 Electronic Flight Information System with

HS34 Nav and GPS ConnectivityDynon Avionics EMS-D120 Engine Monitoring SystemGarmin SL30 Nav/comm transceiverGarmin GTX 327 digital transponderGarmin GPSMAP 496 portable GPS.

Conclusion The flying car concepts will require some more time to

be in reality.

Roadable aircrafts design and development are feasible.

Cost of roadable aircrafts play a vital role in their success.

The success of roadable aircrafts will end uncertain

weather, rising costs, and ground transportation hassles on

each end of the flight.
