Study Notes
ME2511 Aircraft Structures
- Course covers aircraft configuration and internal layout.
- Learning objectives include understanding general aircraft configurations, construction, categories, and layout, focusing on business, freighter, and passenger aircraft.
Aircraft Configuration
- Fuselage, wing, tail structure configurations are key components.
- General fixed-wing aircraft configuration diagrams are presented, showing parts like the vertical stabilizer, rudder, APU exhaust, APU inlet, trailing edge flaps, aileron, wing rip, wing upper surface, upper fuselage, spoilers, leading edge slats, angle of airflow sensor, radomes, static ports, and pitot tubes.
General Aircraft Categories
- Aircraft are categorized based on customer needs.
- Categories include freighter, military, private, passenger, business, and government aircraft.
Aircraft Categories (FAR)
- Federal Aviation Regulations (FAR) govern aircraft categories.
- Categories include normal, utility, acrobatic, and commuter (FAR 23), transport (FAR 25), normal category rotorcraft (FAR 27), transport category rotorcraft (FAR 29), and manned free balloons (FAR 31).
- Hovercrafts are not considered aircraft.
Aircraft Categories - Maximum Take-Off Weight (MTOW)
- MTOW is a crucial factor in aircraft category designation.
- Normal, utility, acrobatic, and commuter category fixed-wing aircraft typically have an MTOW below 8600kg, and fewer than 19 passenger seats.
- Transport category fixed-wing aircraft fall outside the normal category.
Transport Category Aircraft
- Diagrams illustrate cross-sectional and plan views of narrow-body (e.g., Airbus A320) and wide-body (e.g., Boeing 747) aircraft, highlighting compartments like lavatories, galleys, passenger seats, cargo pallets, and overhead racks.
Unique Fuselage Shapes
- Various fuselage shapes are showcased, including the Aero Spacelines Super Guppy, Boeing 747 Dreamlifter, Short Skyvan, and Airbus A380.
Unique Wing Planform
- Different wing planforms, such as sweepback, elliptical, delta, and forward sweep, are illustrated.
Wing Configuration
- Wing configurations, including low wing, mid wing, high wing, inverted gull wing, gull wing, dihedral wing, and anhedral wing are displayed.
Wing Planform Configuration
- Various wing planform configurations, like low, moderate, and high aspect ratios, straight, swept, and forward swept wings are categorized.
Wing Planform Configuration 2
- More specialized wing planforms, such as elliptical, semi-elliptical, tailless delta, tailed delta, cropped delta, compound delta, ogival delta, crescent, cranked arrow, M-wing, and W-wing designs are addressed.
Empennage Section Configuration
- Various empennage configurations, including fuselage mounted, cruciform, T-tail, flying tailplane, tailplane mounted, twin tail boom, wing mounted, V-tail, inverted V-tail, X-tail, pelikan tail, and triple fins, ventral fin are illustrated
Common Empennage Section Configuration
- Common configurations like standard tail, twin tail, T-tail, and V-butterfly tail are detailed.
- These configurations are represented in diagrams.
Empennage Configuration
- Illustrations showcase fuselage mounted, T-tail, cruciform, and butterfly/V-tail, twin-tail design configurations.
Unconventional Aircraft Configuration
- Unconventional configurations such as flying wings (B2 Stealth Bomber), blended-wing aircraft, and the Bumble Bee & Proteus tandem-wing high-altitude aircraft are included.
Landing Gear
- Landing gear supports aircraft on the ground.
- Types: Fixed (low speed aircraft), retractable (more streamlined)
- Landing gear must be strong for landing forces.
- Gear assembly should be light, nose landing gear for steering, main for braking.
Landing Gear Configuration
- Conventional landing gear (pre-WWII aircraft), tail wheel for steering, possibility of nosing over during hard braking.
- Fixed and common in low-speed aircraft, nose wheel for steering during takeoff, no danger of aircraft nosing over during braking.
Landing Gear Configuration 2
- Retractable landing gear is standard in transport, business jets, and military aircraft.
- Increased performance due to reduced parasite drag.
- Nose wheel used for steering.
- Aircraft level during takeoff.
- Number of main landing gear depends on aircraft maximum landing weight.
Aircraft Engine Configurations
- Engine placements include to the nose, under the wing, through the wing, over the wing, and to the fuselage and tail section.
Aircraft Door/Air Stairs (ATR 42)
- Diagrams of the damper assembly, forward latch bolts, latch hooks, hinge seal, and inspection window are provided.
Passenger Aircraft (Airbus A380) Layout
- Detailed layout of the Airbus A380, featuring various compartments, like air conditioning plant, avionics, business class, first class, restaurant, stairs, cargo hatch and duty-free shop, wheel wells, baggage containers, wheel bogies, winglet, flaps, elevator to all decks, galleys, toilets, leading edge flaps, fuel tanks, stateroom, cabins, and pantry
- Parts of engine like fuel tanks, thrust reverse duct, and various fuel foams are also shown.
Passenger Aircraft (Boeing 787-8) Layout
- Detailed layout of the Boeing 787-8, including sections for cockpit, passenger cabins, engine and other parts.
Passenger Aircraft Interior Layout
- Illustrations showcase an economy class cabin interior of an Airbus A340-600 (Qatar Airways).
BA 747 Passenger Aircraft Configuration
- Descriptions for various Boeing 747-400 (744) passenger configuration types (V1, V2, V3), including different seating levels and passenger compartments.
Business Jet Interior Layout
- Image/diagram of a Falcon 7X business jet interior.
Passenger to Freighter Conversion
- Information found in YouTube video, and types of changes/modifications needed in aircraft layouts are referenced for conversion.
Freighter Aircraft Interior Layout
- Illustration of a Boeing 767-300 freighter aircraft interior.
Freighter A/C Internal Structure
- An image showing the internal structure of a freighter aircraft.
