2. INTRODUCTION
VTOL stands for vertical
take-off and landing.
VTOL aircraft that can take
off, hover, and land
vertically.
In VTOL we can remove
the need of runway.

3. What is VTOL ?
 A VTOL aircraft is one that can hover, take
off, and land vertically.
The best-known example is the helicopters and
drones.
 VTOL aircraft can land and take off at any
worst conditions .
3

4. Types of VTOL
 There are two different types of VTOL
technology.
1. ROTORCRAFT
.
2. POWERED LIFT
4

5. Rotorcraft
• Known as rotary wing
aircraft.
• Lift generated by rotor
blades spinning around a
central mast.
• Eg : Helicopters ,
Cyclogyro , Autogyro ,
Gyrodynes.

6. HELICOPTERS
A helicopter is a type of rotorcraft
 Lift and thrust are supplied
by rotors.
It can take off and land vertically,
to hover.
 It can fly forward and backward
It can used in congested or
isolated areas.
6

7. CYCLOGYRO
The cyclorotors as the principal
source of lift, propulsion, and
control.
They are capable of VTOL and
hovering performance like
a helicopter
The wing resembles a paddle
wheel, with airfoils replacing the
paddles.
7

8. AUTOGYRO
Also known as gyroplanes or
gyrocopters .
The rotor is unpowered and rotates
freely in the airflow as the craft travels
forward .
So the craft needs a conventional
powerplant to provide thrust .
8

9. Gyrodynes
It has a separate forward
thrust system of an autogyro.
 Lift during forward flight is
provided by a combination of
the rotor, like an autogyro, as
well as conventional wings.

10. Powered lift
• Powered-lift vehicles are those
that take off and land vertically.
.
• Vectored thrust planes such as
the Harrier Jump jet series also
used powered-lift technology.
• Eg; Convertiplane, Tilt rotor,
Tilt wing, Tail-sitter., vectored
thrust ,
10

11. Convertiplane
Uses rotor power for VTOL and
converts to fixed wing lift in normal
flight.
an aircraft that takes off and lands
like a helicopter and is convertible
to a fixed-wing configuration for
forward flight
This aircraft that converts in
flight to change its method of
obtaining lift.
11

12. Vectored thrust
used powered-lift by
manipulating the thrust from the
engine or motor.
Plane diverted its engine thrust
downward for vertical takeoff
using rotatable engine exhaust.
Harrier jump jet is the known
example.
12

13. Tiltwing
Propellers or rotors fixed to a
conventional wing and tilts the
whole assembly to transition
between vertical and horizontal
flight.
 The wing is horizontal for
conventional forward flight and
rotates up for vertical takeoff and
landing.
13

14. Tail-sitter
A tail-sitter sits vertically on its tail for takeoff and landing,
then tilts the whole aircraft forward for horizontal flight.
When hovering the nose of the aircraft will try to point up for
“level” flight.
14

15. Advantages of VTOL Technology
 energy efficient than those using jet engines.
 Remove the need for runway.
 Time and fuel saving.
 This makes already safe air travel even safer.
 Simplicity (cellular construction)
 Ease of Maintenance
 Safety

17. Future development of VTOL
• Uber has pledged to launch its first flying taxis in
2020 using VTOL.
• Munich based aviation startup aims to offer a flying
taxi service that it will be five times faster than
travelling in a car.
• At the 2017 Geneva Motor show, Airbus showcased a
prototype flying hybrid car.
• Nasa has developed the battery-powered GL-
10,which take off and land vertically .

18. Conclusion
VTOL enables a traveler to travel directly from
point A to point B.
 VTOL transport aircraft is just not economical
in the commercial world.
VTOL technology has an important role for
future development of aviation field.
 VTOL is suitable for use in manned or un-
manned aircraft.
