I believe we have come up with the solution. of How a Flying Car can work in the real world.
this flying car design is technically a helicopter that folds up in to a car.
this design is about function. Ok- so its not as Stylish or exciting as the Moller Skycar.
But this is believable design will probably work in the real world.
as to build a flying car you need a successful aircraft Engineering design like a helicopter.

Note- this is the (single rotor version.) the coaxial twin rotor version of the design concept.
with folding fixed side wings and a single tail pusher propeller.
rotorcraft design that offers more lift capacity with better Top level flying speed and range.
Designed to appeal to customers in the luxury and executive sector –
those who want many of the benefits of a helicopter but Not problem of where to park it and then where
to find car when you need one. versatility is the strength of the Flying Car.
on the down-side
as a helicopter its slow, also as a Car its Big and long with limited interior space.
But on the Up-side its the versatility and speed of getting from Point A to Point B . is its design strength.
powered by a 230kw Gas turbine engine runing on diesel fuel oil.
Air Speed Performance is around 160km/h in the Air. maximum speed of 190km/h with high fuel burn.
this is slow for a helicopter but it will get you there faster than a sports car. roads are never all straight.
on the road its limited to around 140km/h can have maximum speed of 250km/h. but may be unstable.
when powered by the 15kw APU on the road. the car is limited to around 30km/h
powering only the rear electric motor & wheels.
diesel fuel or JP-8
Maximum flight Weight capacity is 1400Kg so it's Only a Pilot and two passengers with a Full tank of fuel.
but with 4 seats. you can have one Pilot and three passengers with less fuel. Flying on a cool day.
or one adult & three children. as most children are smaller and lighter than most adults.
the useful flight Weight capacity is around 300kg to 450kg .
For example Weight capacity is calculated by scales in the vehicles hydraulic suspension linkage.
by measuring Oil pressure in four hydraulic suspension units at the wheels. on land.
also the four hydraulic suspension units are use'd to re-level the vehicle when transforming from a
Car to a helicopter. The main rotor unit & main rotor mast must be level for the actuators to work.
fly by Wire technology is needed as when transforming from a Car to a helicopter.
as standard mechanical linkage as use'd in most helicopters. will Not bend or fold up as needed in
this design. So hydraulic actuators do the work of mechanical linkage. but for safety and the need
to save Weight in not haveing to carrey a extra large electrical storage battery.
fly by Wire technology needs a APU ( Auxiliary Power Unit ) when used with single engine aircraft.
also the APU is used to start the main engine or motor. both the APU & main engine can power the
vehicle's hydraulic & electrical systems. But the main engine also powers the twin Tail rotor motors
and the main rotor when flying. by the way of a gearbox at the bottom of the vehicle. just behind the
vehicles cabin. with a folding driveshaft for the main helicopter mast.
as a Car the main turbine engine also powers the twin wheel motors of the rear and front powertrains.
the rear electric motor. and the front electric motor. the two powertrains are made up of a differential
,its transmission with a electric motor. this car is 4WD.
anther way to do things is
like electric car designs that place motors at or in each wheel, will further reduce weight and improve
efficiency but how ? will it do going off road 4WD. as most Landing Zones are not on hard ground.
as its most likely a flying car will be used in the country not just in big citys.
the cars accelerator is on the floor but the turbine engine accelerator is on a hand grip collective.
so features are incorporated in the electrical transmission to avoid over speeding of the power turbine
with power On then Off in city driveing with the floor accelerator.
The main turbine engine uses diesel fuel. with a single combustor can at the rear of the engine.
at the middle of the turbine engine between the main turbine & the front compressor is a gearbox.
this drives the main electrical generator & a main drive shaft to the main rotor transmission.
there a big magnetic electrical clutch used to disconnect the helicopter transmission when driveing.
a magnetic clutch uses only electrical current input to operant. there are two electrical circuits for
Radio navigation waypoint settings for Landing Zones
This concept of useing video display of timer's & Map's as Driver / Pilot assistance.
flight range For example, IF no flight plan is Enterd at the start of a flight !
Automated timer will show point of No return to the Current Landing Zone or LZ
based on fuel levals at the start & used , time in the Air , GPS specific locations.
maped as the Pilot roam's about in side a shrink circle with the LZ in the middle.
with a Enterd flight plan to a specific location. a back-up Landing Zone may also
be requested by the flight computer. IF the Landing Zone is Not at an airport.
