Aircraft Structure

Major Components (Part Two) Empennage

Aircraft Structure

The empennage includes the entire tail group and consists of fixed surfaces such as the vertical stabilizer and the horizontal stabilizer. The movable surfaces include the rudder, the elevator, and one or more trim tabs. [Figure 2-10] The rudder is attached to the back of the vertical stabilizer. During flight, it is used to move […]

Major Components (Part One) Fuselage and Wings

Aircraft Structure

Although airplanes are designed for a variety of purposes, most of them have the same major components. [Figure 2-4] The overall characteristics are largely determined by the original design objectives. Most airplane structures include a fuselage, wings, an empennage, landing gear, and a powerplant. Fuselage The fuselage is the central body of an airplane and […]

Lift and Basic Aerodynamics

Aircraft Structure

Four forces act upon an aircraft in relation to straight-and-level, unaccelerated flight. These forces are thrust, lift, weight, and drag. [Figure 2-1] Thrust is the forward force produced by the powerplant/propeller. It opposes or overcomes the force of drag. As a general rule, it is said to act parallel to the longitudinal axis. This is […]
