The document outlines the key principles of flight, including a brief history of aviation from da Vinci to the Wright brothers. It then discusses the key atmospheric properties affecting aircraft like temperature, pressure, and density. The main principles of flight covered are Bernoulli's principle explaining lift, and the basic forces of thrust, drag, weight, and lift. It also defines angle of attack and the axis of movement.

4. Brief history
• Leonardo da Vinci made the first real studies of flight in the
1480's. He had over 100drawings that illustrated histheories on
flight.
• . In 1799 Sir George Cayley set forth the concept of the modern
airplane as a fixed-wing flying machine with separate systems
for lift, propulsion, and control. Great progress was made in the
field of aviation
• The first successful powered airplane airplane was created by
Wilburand Orville Wright in 1903 with a gasoline powered
engine After the Wright brothers aircraft development was
literally propelled forward.

5. Introduction
• The principles of flight are the
aerodynamics which deal with the
motion of air and the forces acting on
a body moving relative to that air
thrust, drag, lift, and weight are forces
that act upon all aircraft in flight
• To Understanding how these forces
work and knowing how to control
them with the use of power and flight
controls are essential to flight
• However we must understand the
relationships between the
atmosphere, the aircraft and the
forces acting on it in flight, in order to
make intelligent decisions affecting
the flight safety of both airplanes and
helicopters.

6. Atmospheric affection
• The properties of air that affect aircraft control and performance must
be understood. The definition of the standard atmospheric properties
are based on
• Temperature : which can effect on the kinetic energy of the air particles
• Pressure : Atmospheric pressure varies with altitude
• Density : It varies directly with the pressure and inversely with
• the temperature
• Humidity : Humidity is the amount of water vapor in the air

law of flight

8. BERNOULLI'S PRINCIPLE
• the faster a fluid is moving the lower the pressure
• Air moving over the wing moves faster than the air below. Faster-moving air above exerts less pressure on
the wing than the slower-moving air below. The result is an upward push on the wing--lift

9. BASIC FORCES IN FLIGHT

10. Lift force
• Produced by the dynamic effect
of the air acting on the wing
• Lift is the force created by the
interaction between the wings
and the airflow.

11. WEIGHT/GRAVITY
• Weight is the force caused by the gravitational attraction of earth

12. • Thrust : is The Force That Accelerates The Aircraft in A Forward
Direction
• Drag : is The Opposing Force of Thrust. The Aircraft WhichFlies
Through The Air Experiences Resistance of Air Flow.

13. Angle of Attack
• The angle of attack is the angle between the chord line and the
average relative wind
• Greater angle of attack creates more lift (up to a point).
