How are aerodynamic problems normally classified?
- A.
By magnitude
- B.
By flow environment
- C.
By property of the object
- D.
By degree of altitude
Correct Answer
B. By flow environmentExplanation
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.Rate this question:

What is the mathematical formulation of the conservation of mass in aerospace engineering ?
- A.
Mass conservation constant
- B.
Mass continuity equation
- C.
Mass conservation equation
- D.
Mass continuity constant
Correct Answer
B. Mass continuity equationExplanation
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.Rate this question:

What are the momentum conservation equations of aerospace engineering called?
- A.
Navier-Stokes functions
- B.
Navier-Stokes relation
- C.
Navier-Stokes equations
- D.
Navier-Stokes expression
Correct Answer
C. Navier-Stokes equationsExplanation
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.Rate this question:

Which of these is not a characteristic of supersonic flow?
- A.
Viscous interaction
- B.
High temperature flow
- C.
Flow wave
- D.
Flow temperature flow
Correct Answer
D. Flow temperature flowExplanation
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.Rate this question:

Which of these is the characteristic of supersonic flow?
- A.
Shock wave
- B.
Mach number
- C.
Reynold's wave
- D.
Shock constant
Correct Answer
A. Shock waveExplanation
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.Rate this question:

Which of these fields does not need the service of aerospace engineers?
- A.
Technology
- B.
Space exploration
- C.
Medicine
- D.
Military
Correct Answer
C. MedicineExplanation
Aerospace engineers primarily focus on designing and developing aircraft and spacecraft, as well as related technologies. While technology, space exploration, and the military all require the expertise of aerospace engineers, medicine does not typically require their services. Medicine is a separate field that involves the study and practice of diagnosing, treating, and preventing diseases and injuries in humans. While aerospace technology may have some applications in medicine (such as medical imaging technology), the field of medicine itself does not directly involve the design and development of aerospace vehicles or technologies.Rate this question:

- D.
Paragliding
Correct Answer
D. 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.Rate this question:
