Study Notes
- Understanding the general construction of an aircraft is the main learning objective
Principal Structural Units of a Fixed-Wing Aircraft
- The key structural units include the fuselage, wings, empennage, power plant structures, landing gear attachments and others
- Flight control surfaces and lift augmentation devices are part of wing structures
- The empennage also includes flight control surfaces
Fixed-Wing Aircraft Components
- The wings have power plants and control surfaces like ailerons, flaps, and slats
- Ailerons, flaps and slats are control surfaces of the wing
- The empennage consists of a vertical stabilizer with a rudder and horizontal stabilizers with elevators
- The fuselage has doors and windows, and attachment points for landing gear and wings
The Fuselage
- The fuselage forms the main body
- It is designed to maximize strength while minimizing weight
- Its shape is aerodynamic to reduce drag for efficient performance
- Fuselage provides space for payload, protects passengers, and offers attachment points for other structural parts
The Wings
- Wings act as lifting surfaces
- Wings contribute to lateral stability
- They hold the pylon and nacelle, which houses the engine
- Two types of wing designs exist: semi-cantilever and full cantilever
Semi-Cantilever Wings
- Semi-cantilever wings are externally reinforced by struts and wires
- They can be found on light aircraft designs
Full Cantilever Wings
- Full cantilever wings does not need external support
- They are made from stronger metal
The Empennage
- The empennage, also recognized as tail assembly, comprises vertical stabilizer, horizontal stabilizers, tail cone, and aft pressure bulkhead
- The vertical stabilizer includes the rudder
- The horizontal stabilizers include elevators
Engine Nacelles/Pylons
- Boeing 747 engine pylon and the GE CF6 engine cutaway drawing are key components
Structural Parts of a Helicopter
- Main components include the main rotor hub assembly, main rotor blades, fuselage, landing gear or skid, stabilizer, pylon, tail boom, tail rotor, tail skid, powerplant, airframe and transmission
