ME2511 Aircraft Structures Anatomy of Aircraft MM2511– Revision 2 Anatomy of Aircraft Learning Objectives Fuselage Understanding the general construction Wings of an aircraft Empennage Engine Nacelles/Pylons Principal Structural Units of the fixed-wing aircraft  Fuselage  Wings Flight control surfaces/lift augmentation devices  Empennage Flight control surfaces  Power Plant Structures  Landing Gear Attachments  Others  Fixed-wing aircraft Flaps Ailerons Vertical stabilizer Wing: Rudder Power plants Control surface o Ailerons Elevator o Flaps o Slats Horizontal stabilizer Empennage: Fuselage: Vertical stabilizer Doors o Rudder Windows Horizontal stabilizers Attachment points for o Elevators o Landing Gear o Wings The Fuselage Forms the main body of an aircraft Designed to yield max. strength with min. weight Aerodynamically shaped to develop least drag for most efficient/economic performance Purpose:  Provide space for payload (e.g. crew, passengers, cargo etc) and other items,  Protect passengers from the environment,  Provide attachment points for other structural members namely; wings, empennage section, landing gear, etc. The Wings Primary lifting surfaces of an aircraft Major contributor to lateral stability Holds the pylon and nacelle (engine) 2 types of wing design: Semi-cantilever  Externally reinforced by struts and wires  Found on light aircraft design Full cantilever  No external support required  Made from stronger metal The Empennage The empennage or tail assembly of an aircraft comprises the: Vertical stabilizer Rudder Horizontal stabilizers Elevators Tail cone Aft pressure bulkhead Engine Nacelles/Pylons View of internal structures of major structural units of the L-1011 Lockheed Tristar commercial jet aircraft Structural Parts of an Helicopter  Online links 1) http://arunrajagopal.com/2010/08/12/identify-airbus-from- boeing/ 2) http://www.airlinereporter.com/2010/11/a-great-guide-on-how- to-tell-the-difference-between-airplanes/ 3) http://labkittydesign.hubpages.com/hub/aircraft-identification 4) http://okigihan.blogspot.sg/p/helicopter-structures-structures- of.html 5) https://www.faa.gov/regulations_policies/handbooks_manuals/avi ation/helicopter_flying_handbook/media/hfh_ch04.pdf MM3521 – Revision 1.0
