What are the 5 Major Aircraft Components?

Fuselage

It forms the main body of the aircraft, to which the wings, tailplane, canards, vertical fin, and engine are attached. It takes the form of a tube, housing the flight deck, passenger cabin, freight holds, and the majority of the equipment required to operate the aircraft.

1. Truss Type or Framework Type

2. Monocoque Type

3. Semi-Monocoque Type

What are the 3 Types of Fuselage?

Truss Type

A rigid framework made up of members, such as beams, struts, and bars, designed to resist deformation from applied loads. It is generally covered with fabric.

Truss Type

What type of fuselage?

Monocoque Type

A type of fuselage where the skin bears all the loads placed on the structure, and the shape of the structure provides its strength and rigidity. The skin may be attached to formers to give its basic shape, but it carries all the flight and ground loads.

Monocoque Type

What type of fuselage?

Semi-Monocoque Type

In this type, the loads imposed on the skin are shared by a series of frames, stringers, and formers that are attached to it. Frames strengthen the fuselage and help distribute the load. Stringers are lighter longitudinal members that reinforce the skin, and formers are used to maintain the skin’s profile between frames.

Semi-Monocoque Type

What type of fuselage?

Wings

Previously referred to as main planes, they produce the lift that supports the weight of the aircraft in flight. They must have sufficient strength and stiffness to perform this function effectively.

Wing Spar

Are constructed so that they will absorb the downwards bending stresses when on the ground and the upwards, rearwards, and twisting stresses when in flight.

A wing support of an airplane for sustaining the backward reaction due to the drag of the wing.
