Abstract- These paper focuses on developing an estimation method of flying hover car. The flying hover car is car which
can be use as conjunct function for both travelling on road as well as flying in air. Such a type of model having no wing like
airplanes or no propeller at the top like in helicopter. This car is a combination of 3 things i.e. flying saucer, flying platform
and the car. By using flying saucer design it easy to overcome the weight for taking lift and a flying platform having no wing
or propeller at top and concept of car is use to travelling on road. In this car there are ducted fan which is use to lift the car. A
circular platform non spinning body offer advantages over a conventional wing aircraft. Controlling moment required to
move forward, sideward & reverse in direction is achieved by control vanes. It can have single or double seater capacity.

speed.
I. INTRODUCTION
The purpose of carrying out such type of research is
to build a technique that is contrast with existing
technology available as a flying car. Also to avoid
trouble occurring at the time of flying when we are at
the public place or at heavy traffic in cases of wing or
propeller carrying flying car, because it is not
possible to take off from such a places, they need
large space due to their flying configuration. So this
type of model can be easily overcome this problems.
Flying Hover Car which can be used as a personal car
which carried maximum two person.
II. DETAILS EXPERIMENTAL
2.1. Ducted Fan with Propeller
Ducted fan air vehicles have the ability of forward
flight and are well known for stationary hovering
aerodynamic performance. It is aerodynamically
efficient because the lift generated by the duct can
create a thrust force that is higher than the other
VTOL vehicles, which have no duct and therefore no
hovering flight model. Computer activates control
vanes are used to tilt vehicles in transition to forward
flight, this being achieved by combination of fan
thrust and the control vanes of ducted fan. Compared
with ordinary fixed-wing aircraft, ducted fan has
such advantages:
1. Fixed-wing aircraft needs ground support in
takeoff and landing instead the ducted fan do vertical
takeoff and landing and hover to adapt to the complex
environment of the city or mountain.
2. Compact Structure and High Propulsive Force. The
ducted fan has more compact structure, less drag.
And its flight altitude is closer to fixed-wing aircraft.
So it can fly faster than the equivalent helicopter.
3. The propeller is placed in the ducted fan, which
can obstruct the transmission of aerodynamic noise.
So the noise intensity and propagation distance can be
reduced to some extent. Ducted fan normally having
less and shorter blades than the propellers as shown
Figure 1: Ducted Fan with Propeller
Due to improvements in control theory and
technology, ducted fan vehicles are a more viable
solution for manned aircraft. So that this type of
model can fulfill the requirement of manned vehicle
and it can be mostly applicable for military purpose
also.
2.2. Control Vanes
There are numerous technology we can see for
controlling ducted fan vehicles. Pitching moment
required to move forward, sideward & reverse in
direction of the personal flying hover car is achieved
by
rotating movable control vanes which is
connected to air scoop as shown in fig 2. Joystick is
use for moment of the vanes and thus the thrust force
of the air can be guided towards the required
direction as per need. And also a round shaped nozzle
is fixed between this setup.
By adjusting the rudders at the tip of the duct enables
the vehicle to travel along almost all directions. The
nozzle set up additionally improves the aerodynamic
stability of the vehicle.

This all requirement is fulfill by numbers of engine
available with latest technology like Lycoming O320-B Engine, Rotax 503 Engine etc.
Shifting Mechanism
Shifting mechanism play a role in the flying hover
car. This mechanism like a gear box is design such
that it can be shift alternatively to transform the
roadable car into flying car. Shifting can be possible
by changing the position of the Joystick or lever.
If the car is to be drive on road then the rotary power
of the engine is transmitted from engine towards the
differential of the rear wheel drive. Instead to drive
the car on road it can be easily change and convert
the roadable car into flying can be possible without
any obstacle by shifting the joystick in another
position.
Use of this shifting mechanism is to reduced the cost
which required to drive the engine separately for two
different purpose i.e. rotation motion to propeller in
duct and wheels through differential.
Figure 2. Control Vanes
The magnitude of this contribution of air from the
ducted can be significant a theoretical result which
state that the thrust force of a ducted fan with an
control vanes will be equally divided between
pressure on the rotor and pressure on the duct. A
larger range of flight conditions could be achieved
with zero altitude variation if the number or size of
the exit vanes were increased.
2.4 Aerodynamic Design
This play a vital role in this car. Because this is a
flying car so it is necessary to understand the concept
of aerodynamic regard to flying of aircraft and
roadable car. The similarity between this two is that
one of the goal of aerodynamic is to reduced the drag
the car or aircraft experience so that it can operate
with as much less energy. The size and shape of this
personal flying hover car is made nearly similar to the
flying saucer because air divided smoothly around
rounded leading edge.
2.3 Engine and Mechanism
An engine is designed to convert one form of energy
like chemical energy of gasoline into mechanical
energy in the form of rotating motion. There are some
factor need to be consider at the time of selection of
engine for flying hover car.
1. Power to Weight ratio: This calculation is
commonly applied to engines. Power to weight ratio
is measurement of actual performance of engine.
From the calculation of flying hover car power
needed to fly is around 124 HP (92.468 KW) for
weight 475 kg.
2. RPM : Rotation Per Minute of engine is most vital
factor is to be consider. Rotation of rotor in duct is
proportional to the amount of thrust force of air
produced. So rpm of engine required to take off the
flying hover car is around 6500 rpm. Also the
aerodynamic shape of rotor and numbers of rotor
vanes affected to developed large amount of air.
In this research wings and propeller is remove and
instead that Coanda Effect is use to design this flying
hover car. In the year 1900 Romanian researcher
Henri Coanda states that the tendency of fluid jet to
stay attached to a convex surface. Using this design it
is easy to create strong lower pressure on the top of
the car.
Figure 4.1 Concept Of Flying
The coanda effect provide lift and thrust from a single
ducted rotor blowing thrust force of the air out of the
duct and provide anticipated VTOL (Vertical Takeoff and landing ) like performance.

The future of the flying car will depend on
successful airworthiness and road certification.
III. RESULT AND DISCUSSION
Final conceptual and estimate design of this flying
hover car as shown in fig 3.1. is such that it can be
easily fly in air and also capable to travel on road due
to specially aerodynamic concept.
