<p>SEMINAR ON</p> <p>|FLYING CARS}byShashishekarayya.R.Hiremath 1MJ09MAE12 M.Tech. 2nd semester Dept. Aeronautical Engg., MVJCE-Bangalore</p> <p>OVERVIEWIntroduction Design Approach Design Consideration Design Concepts Conclusion</p> <p>INTRODUCTION What is a Flying car ?</p> <p> Why do we need flying Car ?</p> <p> What is special in designing a flying car ?</p> <p>DESIGN APPROACH Roadable Aircraft</p> <p> Flying Car</p> <p>CONTINUEDu. Dual Mode Design</p> <p>Flying Motorcycle</p> <p>DESIGN CONSIDERATIONS Range Endurance Rate of climb Cruise speed in air Cruise speed in land Airworthiness standards Automobile safety and Emissions</p> <p>CONTINUEDu. Acceptable in flight wing aerodynamics while able to</p> <p>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.</p> <p>DESIGN CONCEPTS Glenn Curtiss in 1917 exhibited his design of flying</p> <p>automobile in Pan- American Aeronautic exposition in New York.</p> <p> Waldo waterman was the first person to be granted a</p> <p>patent on roadable aircraft Arrowbile in 1937.</p> <p>CONTINUEDu.. Robert E. Fulton in 1946 designed a new concept his</p> <p>FA-3-101 Airphibian</p> <p> Convair Air car in 1947</p> <p>CONTINUEDu. Moulton Taylor designed and built Taylor Aerocar in</p> <p>1949</p> <p> Characteristics of Aerocar </p> <p>Crew: One pilot Capacity: One Passenger (2 total) Length: 6.55 m Wingspan: 10.36m Height: 2.18 m Wing area: 15.6 m Empty: 590 kg Loaded: 955 kg Power plant: 1x Lycoming O-290, 135 hp (100 kW)</p> <p> Performance of Aerocar Maximum speed: 112 mph (172 km/h) Range: 300 mi (480 km) Service ceiling: 12,000 ft (3,658 m) Rate of climb: 550 ft/min (168 m/min) Wing loading: 12.5 lb/ft (61 kg/m) Power/Mass: 0.06 hp/lb (100 W/kg)</p> <p> Moller sky car a VTOL prototype invented by Paul</p> <p>Moller.</p> <p> General characteristicsy Capacity: Four passengers y Length: 19.5 ft (5.9 m) y Wingspan: 8.5 ft (2.6 m) y Height: 7.5 ft (2.3 m) y Empty weight: 2,400 lbs (1088 kg) y Useful load: 750 lbs (340 kg) y Power plant: 4 'Rotapower' Wankel engines with ducted fans, 180 hp (134</p> <p>kW) each</p> <p> y y y</p> <p>Performance Maximum speed: 330 mph (531 km/h) at 25,000 ft (7620 m) Cruise speed: 305 mph (491 km/h) at 25,000 ft (7620 m) Service ceiling: 36,000 ft (10973 m) y Rate of climb: 4,800 ft/min (1463 m/min)</p> <p> Terrafugia-TransitionThe Transition is a light sport, roadable aircraft under development by Terrafugia, a small start-up company based in Woburn, Massachusetts</p> <p> General characteristicsy Crew: 1 pilot y Capacity: 2, pilot and passenger y Payload: 430 lb (200 kg) y Length: 19 ft 2 in (5.8 m) y Wingspan: 27 ft 6 in (8.4 m) y Height: 6 ft 3 in (1.9 m) y Empty weight: 890 lb (400 kg) y Useful load: 430 lb (200 kg) y Max takeoff weight: 1,320 lb (600 kg) y Power plant: 1 Rotax 912S, 100 hp (75 kW) @ 5800 rpm (max. 5 minutes), 95 hp</p> <p>(71 kW) @ 5500 rpm (continuous)</p> <p>yy y y y y y</p> <p>Propellers: Prince Aircraft Company, four-bladed "P-Tip" propeller, 1 per engine Cockpit width: 51 in (1.3 m) at the shoulder Fuel capacity: 20 US gal (76 L; 17 imp gal) Length on road: 18 ft 9 in (5.7 m) with elevator up Width on road: 80 in (2.0 m) with wings folded Height on road: 6 ft 9 in (2.1 m) Front wheel drive on road</p> <p>Continued .. Performancey Cruise speed: 100 kts (115 mph or 185 km/h) y Stall speed: 45 kts (51 mph or 82 km/h) y Range: In flight 400 nmi (460 mi; 740 km); on road 600 mi (520 nmi;</p> <p>970 km) y Maximum speed on road: 65 mph (105 km/h) y Fuel economy in cruise flight: 5 US gal (19 L) per hour y Fuel economy on road: 30 mpg (7.8 L/100 km; 36 mpg)</p> <p> Avionics Glass panel; the proof-of-concept airplane includes: y Dynon Avionics EFIS-D100 Electronic Flight Information System with HS34 Nav and GPS Connectivity y Dynon Avionics EMS-D120 Engine Monitoring System y Garmin SL30 Nav/comm transceiver y Garmin GTX 327 digital transponder y Garmin GPSMAP 496 portable GPS.</p> <p>CONCLUSION The flying car concepts will require some more time to be</p> <p>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</p> <p>weather, rising costs, and ground transportation hassles on each end of the flight.</p> <p>THANK YOU</p>
