3. Historical and Societal Influences - Aeronautical Engineering

Question 1

How does Aeronautical effect people’s lives?

(positives)

(try and give 4-6 )

Answer 1

Significantly reduced travel times. Before it the trip from Sydney to London took 6 weeks.

• Royal flying doctors help regional Australia. There are also other rescue mission flights.
• Traveling in time constraints is easier, this also helps with overseas commerce.
• Families who live overseas can still be close.
• Less casualties in the military as there are less ground troops.
• Can fight bush fires to protect property, people and animals.
• Gather news, images and photos.
• Boosted tourism, especially for isolated counties like Australia.

Question 2

How does aeronautical effect people’s lives?

negatives

Answer 2

Pollution: created by piston and turbine engines (exhaust gasses). Fuel dumping is also a thing. And so is noise pollution from turbines. They have been altered for this reason.

Insect Spraying: for land needed (airports etc) major impact on food chain.

Destruction: Aerial bombing has risen since WW2. German industries were destroyed. Vietnam war saturation bombing.

Question 3

What are some important developments in the history of aeronautical engineering?

(Give 2-3 developments)

Answer 3

• The Wright Brothers’ first powered flight of the biplane.
• Introduction of ailerons, a type of flap mounted to the outboard surface of each wing, allowing for variation in lift.
• Development of the turbojet engine.
• Development of the jet engine.
• Introduction of variable geometry wing (swing-wing) technology.
