Aircraft Structure definitions Flashcards
What is the skin
The smooth outer covering of the airframe
What is the frame
Transverse structural member.
Provides aerodynamic shape and rigidity
What is a former
Lighter than a frame, used more for shape
What is a stringer
A long continuous member that assists skin load carrying to other aircraft structures
What is a bulkhead
Major transverse member in the fuselage or wing and other structure
Divides the fuselage into compartments
What is a lightening hole
A hole in a member to decrease weight with strength maintained by flanging around the hole
What is a longeron
Main longitudinal structural member (heavier than stringer)
Travels longways down the fuselage
What is a stringer
Long continuous member that assists skin load carrying to other structural members
What is a stiffner
strip or beam attached to sheet to resist load.
Short component to stiffen localised area
What is a doubler
A piece of sheet or strip placed against aircraft skin to provide stiffness or additional strength
What is a cap
Longitudinal member at the top and bottom of a beam often called a boom
What is a web
Vertical member of a beam, spar or length of wing providing strength to resist shear and keep upper and lower booms apart
What is a boom
Longitudinal structural member of a spar
What is a rib
Structural cross pieces combining with spars and stringers to make the frame work of a wings, ailerons, elevators, rudders and stabilisers. (makes the aerofoil shape)
What is cantilever construction
Supported internally by structural members assisted by the skin
