1
Q

Entry requirements for aeronautical engineering degrees

A

You’ll need to be highly competent in mathematics and physics in order to apply – expect your competency in these two subjects to be rigorously tested.

2
Q

what is the study of aeronautical enginnering

A

Aeronautical engineering is the study of the design, development, manufacture, maintenance and control of machines or vehicles operating in the earth’s atmosphere or in outer space.

3
Q

-what are some current aeronautical enginnering projects

A
  • Design satellite phone technology so that data can be sent and received from remote areas.
  • Work on the team planning a shuttle trip to service the Hubble Space Telescope.
  • Design airplane wings that change shape to enhance maneuverability.
  • Build satellites that help us monitor global climate changes from space.
4
Q

fatigue testing determines the response of a material to ?

A

Regular and repetitive cyclic loading.

Temperature will affect this response and therefore often a variable controlled for in fatigue testing

5
Q

which of the following describes jet engines

  • gas turbine ?
  • propeller driven ?
  • orbital engine ?
  • internal combustion engine ?
A

jet engines are gas turbine engines dispite the gas turbine may drive a propeller

6
Q

polymers may best be described as ?

A

polymers may best be described as carbon based and comprised of long chain molecules

7
Q

what does magnetic partical testing identify ?

A

magnetic particle is used for surface testing of ferrous metals, it does not identify facture surfaces and cannot be used on aluminuim as it is a non-ferrous metal

8
Q

fibre-composite materials exhibit their greatest strength when subjected to what type of load ?

A

tensile loads

9
Q

surface corrosion of aluminium can be minimised by ?

A

surface corrosion can be minimised by anodising the aluminium which provides a protective layer to the surface

10
Q

the term lift to drag is best described as ?

A

the term lift to dragis best described as

  • the aerodynamic efficiency of an airfoil
  • varying with the angle of attack of the airfoil
  • a ratio of the relationships between lift and drag produced by a airfoil
11
Q

a local airport is to be upgraded discuss some issues that would need to be considered

A
  • supporting infrastructure
  • increased size to allow take off and landings
  • new flight paths for aircraft landing and taking off
  • need for increased services due to either frequency or size of aircraft
  • impact on flora and fauna
  • increased noise during construction and increased traffic after construction
12
Q

explains bernoullis principle

A

bernoullis principle explains the relationship between a fluids kinetic energy and its potential energy.it states any increase in a fluids speed will also be accompanied by a corresponding reduction in pressure

13
Q

what is a elevator ?

A

a elevator is a hinged section of the horizontal stabilizer adding or subtracting lift from the tail

14
Q

what is a rudder ?

A

The rudder is the primary control in sideways movement usually hinged and attached to the trailing edge of the vertical stabiliser on the aircrafts tail

15
Q

what does altimeter measure

A

an altimeter is an instrument which senses changing air pressure in order to measure altitude

16
Q

what are some methods of limiting corrosion in aircraft

A
  • regular cleaning of surfaces to remove corrosive materials such as salt spray
  • surface treatments and coatings such as anodising to protect exposed surfaces
  • sacrificial anodes
