Which of the following materials is commonly used in fighter jets to reduce weight?

• Aluminium

• Carbon fibre reinforced polymer

• Steel

• Copper

Answer explanation

Carbon fibre reinforced polymer is favored in fighter jets for its high strength-to-weight ratio, making it ideal for reducing overall weight while maintaining structural integrity, unlike heavier materials like steel or copper.

What is a significant feature of the Boeing 787 Dreamliner?

• It is the first commercial aircraft with a carbon fibre composite fuselage

• It is the largest aircraft ever built

• It uses only solar power for flight

• It can land on water

Answer explanation

The Boeing 787 Dreamliner is notable for being the first commercial aircraft to feature a carbon fibre composite fuselage, which significantly reduces weight and improves fuel efficiency, unlike the other options listed.

Which university in Australia offers a course in Aeronautical Engineering?

• University of Melbourne

• University of Sydney

• University of Adelaide

What is the main employer of aeronautical engineers in Australia?

• Automotive industry

• Defence Forces

• Pharmaceutical companies

• Textile industry

Answer explanation

The main employer of aeronautical engineers in Australia is the Defence Forces, as they require expertise in aircraft design, maintenance, and operations, which aligns with the skills of aeronautical engineers.

Which of the following is a key material property sought in aeronautical engineering?

• High electrical conductivity

• High strength to weight ratio

• High thermal expansion

• High magnetic permeability

Answer explanation

In aeronautical engineering, a high strength to weight ratio is crucial for ensuring that aircraft are both strong and lightweight, enhancing performance and fuel efficiency. Other options are less relevant to this field.

What is the primary concern of aerospace engineers compared to aeronautical engineers?

• Space flight and its related requirements

• Designing commercial airliners

• Developing automotive engines

• Overseeing airport operations

Answer explanation

Aerospace engineers focus on space flight and its related requirements, while aeronautical engineers concentrate on aircraft design and operation within the Earth's atmosphere.

What is the purpose of a patent in engineering?

• To increase the cost of production

• To legally protect new ideas and developments

• To reduce the lifespan of a product

• To ensure all designs are publicly available

Answer explanation

The purpose of a patent in engineering is to legally protect new ideas and developments, ensuring that inventors can secure their innovations from unauthorized use, which encourages further innovation.

Which of the following is an example of industrial espionage?

• Legally licensing a patented design

• Copying a registered design without permission

• Publishing a research paper

• Attending a public engineering conference

Answer explanation

Copying a registered design without permission is a clear act of industrial espionage, as it involves stealing proprietary information. The other options involve legal or public activities that do not constitute espionage.

What is a significant challenge faced by Boeing in developing the 787 Dreamliner?

• Achieving solar-powered flight

• Developing a carbon fibre composite fuselage

• Designing a supersonic passenger jet

• Creating a fully autonomous aircraft

Answer explanation

A significant challenge for Boeing in developing the 787 Dreamliner was creating a carbon fibre composite fuselage, which was crucial for reducing weight and improving fuel efficiency, setting it apart from traditional aluminum designs.
