aeronautical

Question 1

Entry requirements for aeronautical engineering degrees

Answer 1

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.

Question 2

what is the study of aeronautical enginnering

Answer 2

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.

Question 3

-what are some current aeronautical enginnering projects

Answer 3

• 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.

Question 4

fatigue testing determines the response of a material to ?

Answer 4

Regular and repetitive cyclic loading.

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

Question 5

which of the following describes jet engines

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

Answer 5

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

Question 6

polymers may best be described as ?

Answer 6

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

Question 7

what does magnetic partical testing identify ?

Answer 7

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

Question 8

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

Answer 8

tensile loads

Question 9

surface corrosion of aluminium can be minimised by ?

Answer 9

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

Question 10

the term lift to drag is best described as ?

Answer 10

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

Question 11

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

Answer 11

• 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

Question 12

explains bernoullis principle

Answer 12

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

Question 13

what is a elevator ?

Answer 13

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

Question 14

what is a rudder ?

Answer 14

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

Question 15

what does altimeter measure

Answer 15

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

Question 16

what are some methods of limiting corrosion in aircraft

Answer 16

• 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
