Study Notes
ME2511 Aircraft Structures
- Course covers aircraft configuration and internal layout
- Learning objectives include understanding general aircraft configurations, construction, categories and layout for different types of aircraft (business, freighter, passenger)
Aircraft Configuration
- Fuselage configuration: Describes the shape and structure of the fuselage
- Wing configuration: Describes the shape, placement, and structure of the wings
- Tail configuration: Describes the shape, placement, and structure of the tail assembly
- Landing gear configuration: Describes the gear arrangement and function of the landing gear
- Understanding general aircraft configurations, construction, categories and layout is crucial to designing and understanding aircraft
General Fixed-Wing Aircraft Configuration
- Diagrams show various aircraft components (e.g., wing upper surface, vertical stabilizer, rudder, APU exhaust, APU inlet, trailing-edge flaps, ailerons, wing tip, static ports, pitot tubes, engine intake)
- Key components and their functions are highlighted
General Aircraft Categories
- Types of aircraft: includes freighter, military, private, passenger, business, and government aircraft
- Categorization: based on customer needs and determined by the particular aircraft configuration
Aircraft Categories
- Federal Aviation Regulations (FAR) are mandates that govern all aspects of aviation in the US
-
FAR categories of aircraft
- Normal, Utility, Acrobatic and Commuter Category Fixed-Wing Aircraft (FAR 23)
- Transport Category Fixed-Wing Aircraft (FAR 25)
- Normal Category Rotorcraft (FAR 27)
- Transport Category Rotorcraft (FAR 29)
- Manned Free Balloons (FAR 31)
Aircraft Categories (Maximum Take-Off Weight)
- MTOW: Maximum Take-Off Weight
- Normal, Utility, Acrobatic and Commuter Category fixed-wing aircraft (FAR 23) have a maximum weight less than 8600 kg and fewer than 19 passenger seats
- Transport category fixed-wing aircraft (FAR 25) encompasses aircraft not classified under the normal category
Transport Category Aircraft
- Explains the differences between narrow and wide-body aircraft configurations
- Details diagrams illustrating plan and cross-sectional views of aircraft interiors
- Shows the positions of lavatories, galleys, passenger seats, and cargo pallets, highlighting differences in seating arrangements
Unique Fuselage Shapes
- Images of different aircraft featuring unique fuselage designs (e.g., Aero Spacelines Super Guppy, Boeing 747 Dreamlifter, Airbus A380, Short Skyvan)
Unique Wing Planform
- Illustrations and examples of different wing planform configurations
- Sweepback wing planform
- Delta Wing Planform
- Elliptical wing planform
- Forward sweep wing planform
Wing Configuration
- Displays different wing configurations, including low wing, mid wing, high wing, inverted gull wing, gull wing, dihedral wing, and anhedral wing
Wing Planform Configuration
- Presents various wing planform configurations based on aspect ratio:
- Low aspect ratio, moderate aspect ratio, and high aspect ratio
- Different types of swept, tapered, reverse tapered, compound tapered wings, and others
Wing Planform Configuration 2
- Illustrates various delta wing configurations (e.g., tailless delta, tailed delta, cropped delta, compound delta, ogival delta, crescent, cranked arrow, M-wing, and W-wing)
Empennage Section Configuration
- Diagrams showcasing different empennage configurations (e.g., fuselage-mounted, cruciform, T-tail, flying tailplane, tailplane-mounted, twin tail boom, wing mounted, V-tail, inverted V-tail, X-tail, Pelican tail, ventral fin, and triple fins)
Common Empennage Section Configuration
- Details standard tail, twin tail, T-tail, and V-butterfly tail configurations with labels for components like rudder, elevators, and fins

- Illustrations of unconventional aircraft configurations such as flying wing (B2 Stealth Bomber), Bumble Bee, blended-wing aircraft, and Proteus tandem-wing high-altitude aircraft
Landing Gear
- Supports the aircraft during ground operations
- Two main types: fixed and retractable
- Fixed landing gear simple but produces drag during flight. Commonly used for low-speed aircraft.
- Retractable landing gear more streamlined reduces drag to increase performance, complex and commonly found in higher speed aircraft
- Landing gear must be strong and lightweight to withstand landing forces and prevent aircraft from tipping over
Landing Gear Configuration
- Shows conventional landing gear configuration (primarily from pre-WWII aircraft).
- Details tail-wheel steering and possibility of the nose or tail being lifted during hard braking of low-speed aircraft.
- Displays fixed-landing-gear configuration commonly used for low-speed aircraft
- Shows the configurations commonly used for aircraft with nose wheel steering and take-off and landing without risk of aircraft tipping
Landing Gear Configuration 2
- This configuration features retractable landing gear in standard category transport aircraft, business jets, and military aircraft
- This features reduced drag and improved performance compared to previous landing gear configurations
- Characteristics include nose wheel steering, aircraft level during takeoff, and the number of main landing gears depending on the aircraft's weight
Aircraft Engine Configurations
- Describes various engine placements on aircraft. Includes engines placed in front, under, and through the wings, and at rear fuselage
