SkyCruiser

 

 

 

SkyCruiser is a concept 5-seat hybrid VTOL transformer airplane with road-drive ability.
VTOL, vertical take off and landing, enables a traveler to travel directly from point A to point B,
instead of going from point A to an airport in a car say, then fly from the airport to another airport, and
then drive with a car from the other airport to point B. Rather than spending 3 to 4 hours going from LA to San
Francisco, for example, SkyCruiser takes you directly to your destination, point to point, in just a little over 1 hour.

Airplane Configuration - Fast and efficient forward flight

  • 505 kph / 314 mph cruise
  • 3 l per passenger per 100 km (76 passenger miles per g)
  • Hybrid power: ICU mated to electric grid driving electric motors

 

 

VTOL Configuration - Safe and quiet electric multirotor system

  • 8 independent VTOL rotors
  • Redundancy for extra safety
  • Arms and rotors fold away during switchblade transformation

 

 

Road Drive Configuration - For short trips on land

  • Wheel mounted electric motors, 150 hp total
  • Max speed: 120 kph / 75 mph
  • 0 to 100 kph (0 to 62 mph) in 7 s

 

 

 

 

 

 

Technical Data and Details

Switchblade Mechanism

The patent pending switchblade mechanism forms the basis of the transformation of SkyCruiser and SkyProwler. Airplanes need to fly fast and to fly fast you need to be as aerodynamically clean as possible. That's why airplanes are long and narrow, somewhat drop-shaped and with as few 'things' sticking out as possible.

For vertical take-off and landing on the other hand, you need to be the opposite of aerodynamic. The more things you have sticking out producing lift (think of the extreme of a parachute for example) the easier it is to hover. This is one of the main reasons that helicopters which a great at hover, are not very good at forward flight, being slow as well as needing a lot of fuel.

The switchblade mechanism transforms an aircraft from the aerodynamically clean airplane configuration to the VTOL configuration, which features a number of rotors that together have a large rotor disc area that is ideal for hovering at low power.

The switchblade mechanism is of similar technical complexity as a gear retraction mechanism and in itself adds very little weight to SkyCruiser and SkyProwler.
