4. Lift and Basic Aerodynamics
Four forces act upon an aircraft in relation to straight-and-level, unaccelerated flight.
These forces are thrust, lift, weight, and drag.

Describe what is CG.
What is the axis of flight that controls yaw?

6. Lift and Basic Aerodynamics
The position of the CG of an aircraft determines the stability of the aircraft in flight.
As the CG moves rearward (towards the tail) the aircraft becomes more and more dynamically unstable.

Describe what is CG.
What is the axis of flight that controls yaw?

8. Lift and Basic Aerodynamics
The longitudinal or roll axis extends through the aircraft from nose to tail, with the line passing through the CG.

9. Warm-Up – 8/25 – 10 minutes

Describe what is CG.
What is the axis of flight that controls yaw?

10. Lift and Basic Aerodynamics
One of the most significant components of aircraft design is CG.
It is the specific point where the mass or weight of an aircraft may be said to center; that is, a point around which, if the aircraft could be suspended or balanced, the aircraft would remain relatively level.

11. Warm-Up – 8/25 – 10 minutes

12. Lift and Basic Aerodynamics
The vertical, or yaw, axis passes through the aircraft vertically, intersecting the CG.

24. Parts of an Aircraft

25. Major Components
Although airplanes are designed for a variety of purposes, most of them have the same major components.
Most airplane structures include a fuselage, wings, an empennage, landing gear, and a powerplant.

26. Major Components Fuselage
The fuselage is the central body of an airplane and is designed to accommodate the crew, passengers, and cargo.
Older types of aircraft design utilized an open truss structure constructed of wood, steel, or aluminum tubing.

27. Major Components Fuselage
The most popular types of fuselage structures used in today’s aircraft are the monocoque (French for “single shell”) and semimonocoque.

28. Major Components Wings
The wings are airfoils attached to each side of the fuselage and are the main lifting surfaces that support the airplane in flight.

29. Major Components Wings
Wings may be attached at the top, middle, or lower portion of the fuselage.
These designs are referred to as high-, mid-, and low-wing, respectively.

30. Major Components Wings
Airplanes with a single set of wings are referred to monoplanes, while those with two sets are called biplanes.

31. Major Components Wings
Many high-wing airplanes have external braces, or wing struts, which transmit the flight and landing loads through the struts to the main fuselage structure.

32. Major Components Wings
Since the wing struts are usually attached approximately halfway out on the wing, this type of wing structure is called semi-cantilever.
A few high-wing and most low-wing airplanes have a full cantilever wing designed to carry the loads without external struts.

33. Major Components Wings
The principal structural parts of the wing are spars, ribs, and stringers.
These are reinforced by trusses, I-beams, tubing, or other devices, including the skin.

34. Major Components Wings
The wing ribs determine the shape and thickness of the wing (airfoil).

35. Major Components Wings
In most modern airplanes, the fuel tanks are either an integral sealed compartment part of the wing’s structure itself, or they consist of flexible containers mounted inside of the wing.

36. Major Components Wings
Attached to the rear or trailing edges of the wings are two types of control surfaces referred to as ailerons and flaps.

37. Major Components Wings
Ailerons extend from about the midpoint of each wing outward toward the tip, and move in opposite directions to create aerodynamic forces that cause the airplane to roll.

38. Major Components Wings
Flaps extend outward from the fuselage to near the midpoint of each wing.

39. Major Components Wings
The flaps are normally flush with the wing’s surface during cruising flight.
When extended, the flaps move simultaneously downward to increase the lifting force of the wing for takeoffs and landings.
