Day 6 Outside Work: Aircraft Structures Flashcards
What is the primary advantage of integrating advanced composites into the aircraft structure?
They reduce the aircraft’s weight significantly.
How does the fuselage of pressurized aircraft manage stress from pressurization and depressurization cycles?
It is designed to resist metal fatigue and cracking.
How does the semimonocoque fuselage achieve its strength?
Through a combination of skin and internal structure to distribute loads.
What maintenance documentation is required for large aircraft?
Volumes of maintenance documentation detailing thousands of procedures.
How does variable geometry or ‘swing-wing’ design benefit an aircraft?
It allows the aircraft to adjust wing configuration in flight.
What role does the corrugated sheet play in wing construction?
It helps the wing better carry tension and compression loads.
How does a turboshaft engine primarily differ from a turbojet?
It uses most of the energy to drive a turbine rather than producing thrust.
What is the significance of the Type Certificate Data Sheet (TCDS) in aircraft maintenance?
It contains critical information about the aircraft.
What is the function of wing spars in aircraft design?
To serve as the principal structural members of the wing.
What is a stressed-skin design in aircraft construction?
The skin is designed to carry part of the flight and ground loads.
What does ‘semimonocoque’ imply about the aircraft’s construction?
The structure relies largely on its skin to support loads.
Why might a fuel-carrying bladder or tank be used in an aircraft wing?
To store fuel efficiently within the structure.
What is the benefit of using a truss structure in aircraft design?
It provides a rigid structure that can support more weight.
What design feature allows for higher speeds in modern aircraft?
Lighter, more aerodynamic fuselage designs.
Why are hydraulic systems widely used in aircraft controls?
They provide a more responsive control system.
How do manufacturers ensure the durability of the aircraft skin against environmental challenges?
By applying specialized protective coatings.
Why is the design of access and inspection panels important in aircraft maintenance?
To allow for easy access to inspect and service various components.
What is the purpose of slats in aircraft wing design?
To allow the wing to generate more lift at slower speeds.
What are chip detectors in helicopter transmissions used for?
To alert pilots of potential internal problems.
What is the main purpose of stringers in aircraft fuselage construction?
To provide additional longitudinal support and distribute load.
What is a primary characteristic of a honeycomb panel in aircraft structures?
It is lightweight and has high strength.
Which type of wing construction is often used in air transport category aircraft due to its ability to handle tension and compression loads effectively?
Box beam wing construction.
Why are wing tips on some aircraft equipped with a Lucite rod?
To transmit light to the leading edge to indicate operational lights.
What type of materials is typically used for the skin of high-speed aircraft to manage increased wing loading?
Chemically milled aluminum.
Why is the pressurization of the aircraft cabin crucial at high altitudes?
To ensure adequate oxygen levels for passengers.
