Which of these is not related to aerospace engineering?

Propulsion
Avionics
Structural analysis
Paragliding

Correct Answer

A. Paragliding

Explanation

Paragliding is not related to aerospace engineering because it involves the recreational activity of flying lightweight, free-flying aircraft without the use of an engine. Aerospace engineering, on the other hand, focuses on the design, development, and production of aircraft and spacecraft, including propulsion systems, avionics, and structural analysis. Paragliding falls under the category of recreational sports and does not involve the same level of engineering and technology as aerospace engineering.

Which of these is the characteristic of supersonic flow?

Shock wave
Mach number
Reynold's wave
Shock constant

Correct Answer

A. Shock wave

Explanation

Supersonic flow is characterized by the presence of shock waves. Shock waves are abrupt changes in pressure, temperature, and density that occur when an object moves faster than the speed of sound in a fluid medium. These shock waves are caused by the compression of air molecules as they are pushed aside by the object moving through the fluid. Therefore, the presence of shock waves is a characteristic of supersonic flow.

What are the momentum conservation equations of aerospace engineering called?

Navier-Stokes functions
Navier-Stokes relation
Navier-Stokes equations
Navier-Stokes expression

Correct Answer

A. Navier-Stokes equations

Explanation

The momentum conservation equations in aerospace engineering are called Navier-Stokes equations. These equations describe the motion of fluid substances, including air, and are fundamental in studying the behavior of fluids in various aerospace applications. The Navier-Stokes equations take into account the conservation of momentum, mass, and energy, and are used to analyze and predict the flow of fluids around aircraft, rockets, and other aerospace vehicles.

How are aerodynamic problems normally classified?

By magnitude
By flow environment
By property of the object
By degree of altitude

Correct Answer

A. By flow environment

Explanation

Aerodynamic problems are normally classified by flow environment. This means that the classification is based on the type of flow that the object is experiencing, such as subsonic, transonic, supersonic, or hypersonic flow. This classification helps in understanding and analyzing the aerodynamic behavior and performance of the object in different flow conditions.

Which of these personalities was a pioneer in aeronautical engineering?

Yuri Gagarin
Neil Armstrong
Jay Logan
George Cayley

Correct Answer

A. George Cayley

Explanation

George Cayley is the correct answer because he was a pioneer in aeronautical engineering. Cayley is often referred to as the "father of aviation" for his significant contributions to the field. He made important advancements in the understanding of aerodynamics and designed the first successful human-carrying glider. Cayley's work laid the foundation for modern aviation and his principles are still used in aircraft design today.

Which of these is not a characteristic of supersonic flow?

Viscous interaction
High temperature flow
Flow wave
Flow temperature flow

Correct Answer

A. Flow temperature flow

Explanation

The term “Flow temperature flow” does not appear to be a characteristic of supersonic flow. The other terms you mentioned could be related to supersonic flow in the following ways:
Viscous interaction: In fluid dynamics, viscosity plays a significant role. In supersonic flow, viscous interactions can occur, especially near the boundary where the flow slows down and can become subsonic.
High temperature flow: Supersonic flow can often involve high temperatures, especially in the case of supersonic aircraft or spacecraft re-entering the Earth’s atmosphere.
Flow wave: This could refer to the shock waves that are a characteristic feature of supersonic flow.

What is the mathematical formulation of the conservation of mass in aerospace engineering ?

Mass conservation constant
Mass continuity equation
Mass conservation equation
Mass continuity constant

Correct Answer

A. Mass continuity equation

Explanation

The mathematical formulation of the conservation of mass in aerospace engineering is described by the mass continuity equation. This equation states that the rate of change of mass within a control volume is equal to the net mass flow rate into or out of the control volume. It is an important equation in fluid dynamics and is used to analyze the flow of fluids in aerospace systems.
