Lift and Basic AerodynamicsFour forces act upon an aircraft in relation to straight-and-level, unaccelerated flight.
These forces are thrust, lift, weight, and drag.Slide5

Lift and Basic AerodynamicsThe 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.Slide7

Lift and Basic AerodynamicsOne 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.Slide11

Parts of an AircraftSlide25
Major ComponentsAlthough 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.Slide26
Major ComponentsFuselageThe 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. Slide27
Major ComponentsFuselageThe most popular types of fuselage structures used in today’s aircraft are the monocoque
(French for “single shell”) and semimonocoque.Slide28
Major ComponentsWingsThe wings are airfoils attached to each side of the fuselage and are the main lifting surfaces that support the airplane in flight
.Slide29
Major ComponentsWingsWings 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.Slide30
Major ComponentsWingsAirplanes with a single set of wings are referred to monoplanes, while those with
two sets are called biplanes.Slide31
Major ComponentsWingsMany high-wing airplanes have external braces, or wing struts, which transmit
the flight and landing loads through the struts to the main fuselage structure. Slide32
Major ComponentsWingsSince 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.Slide33
Major ComponentsWings
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.Slide34
Major ComponentsWings
The wing ribs determine the shape and thickness of the wing (airfoil).Slide35
Major ComponentsWings
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.Slide36
Major ComponentsWings
Attached to the rear or trailing edges of the wings are two types of control surfaces referred to as ailerons and flaps.Slide37
Major ComponentsWings
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.Slide38
Major ComponentsWings
Flaps extend outward from the fuselage to near the midpoint of each wing. Slide39
Major ComponentsWingsThe 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.Slide40
