AIRCRAFT STRUCTURES II Type of load-bearing structure distributes PRELIMS aerodynamic loads to the fuselage: Wing Spars Type of wings commonly used in small aircraft for A wing with tips lower than root is 1/1 known as their simplicity: Rectangular Wings Anhedral. Wing design angles backward from its root: Type of wing design is characterized by its Sweptback wing triangular shape: Delta Wing Type of fuselage relies largely on the strength of Design philosophy involved evaluating a its skin to carry loads: Monocoque structure to ensure it can withstand loads Fixed surface in the empennage that helps despite damage: Damage tolerance stabilize the aircraft: Horizontal Stabilizer Not a type of fuselage construction: Multicoque Primary material used in the construction of The principal longitudinal member in a semi- truss fuselages: Wood monocoque fuselage: Longerons The phenomenon of material fracturing after Part of aircraft that provides directional stability: repeated stress cycles is known as: Fatigue Vertical Stabilizer Type of fuselage construction uses both a Material that is commonly used in primary framework and load bearing skin: Semi- aircraft structures for its high strength: monocoque Aluminum Alloys Wing shape is considered the most Essential for longitudinal stability of an aircraft: aerodynamically efficient but complex to Horizontal Stabilizer manufacture: Elliptical Structural stress produces twisting: Torsion Secondary structure in an aircraft: Fairings Primary structure of an aircraft: Wing spars Aircraft part that provides control over the yaw Structure in the aircraft that is designed to isolate movement: Rudder the engine compartment: Firewall Type of aircraft wing is simplest to manufacture: Not structural stress experience by aircraft: Rectangular Wing Inflation Stress that resists a crushing force is known as: Structures designed to improve the aircraft’s fuel Compression efficiency: Fuselage The structural component that resists forces Purpose of the aircraft’s empennage: Stabilize trying to pull it apart: Tension the aircraft. Component that is responsible for lateral control The purpose of stringers in the fuselage is to: of an aircraft: Ailerons Transmit skin loads to body frames Component of the aircraft is essential for Not a factor in selecting materials for aircraft supporting its weight during landing: Landin gear structures: Color Part of the aircraft provides a smooth airflow Purpose of a spar in a wing is to: Carry load from over the engine: Cowling fuselage to the wing tips Construction type uses diagonal bracing Duplication of structural members to ensure load extensively: Truss distribution if one fails: Fail-Safe Primary function of the landing gear is to: The primary function of the ailerons on an Support the aircraft during takeoff and landing aircraft is to: Control Roll Wing type typically used to provide lateral Design narrows towards the tip and is stability: Dihedral Wing structurally more efficient: Tapered wing The tail cone of the empennage serves to: Streamline the aft of the fuselage Primary function of fuselage: house cargo, controls, and passengers Historical figure is known for pioneering directional control of aircraft: George Cayley Not an aspect of aircraft design: Interior design Aircraft structure primarily supports aerodynamic gravitational and operational loads: Primary structure Part of the aircraft is responsible for housing the engine: Nacelle Wright brothers are best known for: Creating the first powered airplane Type of wing that is most commonly associated with fighter jets for high-speed maneuvers: Delta wing A control surface located on the tail of an aircraft is called: Rudder Primary role of the engine mounts: Fasten the engine to the nacelle
