Aircraft Construction Flashcards
Whats the most common method for attaching metallic structures?
Riveting.
What allows structural parts to be held together but also disassembled?
Bolts.
What type of pin holds the engines onto the wing?
Fuse pin.
What food is an example of a monocoque?
An egg.
The pressure hulk is found between the forward and rear blanks.
Bulkheads
What aircraft example has a cantilever wing?
A320.
What aircraft example has a semi-cantilever wing?
Cesna.
Why do jets have cantilever wings and not externally braced wings?
Struts produce drag.
Which direction do ribs run along a wing?
Vertically.
Which direction do ribs run along a wing?
Vertically.
Horizontally.
What is a wet wing?
A wing with fuel inside it.
What do linked spars create which adds to wing strength by reducing twisting?
Torsion box.
What are two reasons for wing torsional stresses? In regard to engine position and CoG position.
Engine thrust position and difference in COG and COP position.
Where do manufacturers put engines to reduce wing flutter in regard to centre of gravity?
Ahead of CoG.
The horizontal stabiliser provides what directional stability?
Longitudinal.
What type of stall is common in a T-tail?
Deep stall.
The pressure hull experiences blank and blank stress during the pressurisation cycle.
Hoop and axial.
The ratio of the change in size of the deformed structure to the size of the non-deformed structure is called…
Strain.
How may corrosion in aluminium be identified?
Grey powder
When in a gust a wing bends downwards, aileron flutter might occur if the aileron deflects: up/down
Up
With non-load carrying skin, the wing bending moment is carried by the…
Spars
What is the main purpose of flight-deck windshield heating? To heat up the blank and increase blank resistance.
Vinyl and impact
Which structural element of the fuselage helps most to endure twisting and torsional loads?
Longerons
