Q:

Which of the following is not an air-breathing engine?

A) Turbojet B) Turbofan
C) Rocket D) Scramjet
 
Answer & Explanation Answer: C) Rocket

Explanation: Unlike turbojet, turbofan, scramjet, ramjet or turboprop engines, rockets are not air-breathing engines. It carries both fuel and oxidizer along with it, while the other engines suck in air to undergo combustion with the stored fuel.

Q:

What is the energy released (or absorbed), or the enthalpy change when one mole of a chemical compound is formed from its constituent atoms or elements at one bar and isothermally at 25°C?

A) Heat of formation B) Heat of reaction
C) Gibbs free energy D) Latent heat of vaporization
 
Answer & Explanation Answer: A) Heat of formation

Explanation: This is the definition of heat of formation. In this reaction, each of the reactants and products are in its thermodynamic standard state and at the reference pressure and temperature.

Q:

For a constant thrust of 6000 N, find the total impulse for the burning time of 3s.

A) 36000 Ns B) 18000 Ns
C) 9000 Ns D) 0 Ns
 
Answer & Explanation Answer: B) 18000 Ns

Explanation: Here we assume that the start and stop transients are negligible during the operation of the system. Then, for a constant thrust (F), and for the total burning time of t seconds, the total impulse It = Ft.
It = 6000 x 3 = 18000 Ns

Q:

A rocket engine moving at 500 m/s produces a total thrust of 9563 N, consuming propellants at the rate of 4.55 kg/s. The energy content of the propellants is 5.35 MJ/kg. Find the effective exhaust velocity.

A) 2100 m/s B) 3936 m/s
C) 1555 m/s D) 1400 m/s
 
Answer & Explanation Answer: A) 2100 m/s

Explanation: Rocket thrust is the product of mass flow rate and effective exhaust velocity. Using this,
ue = T/m
= 9563/4.55
? 2100 m/s.

Q:

Strap-on booster stages are an example of ______ staging.

A) parallel B) tandem
C) partial D) piggyback
 
Answer & Explanation Answer: A) parallel

Explanation: When two or more booster stages are attached to the lower stage of the vertical configuration of a rocket vehicle, such a configuration is called as parallel staging. In this case, the booster stages are “strapped” on to the lower stage and this allows an increase in the vehicle performance.

Q:

The volume of the combustion chamber is selected on the basis of which of these factors?

A) Mixing, evaporation and complete combustion of the propellants B) Mixing and complete combustion of the propellants, but not its evaporation
C) Evaporation and complete combustion of the propellants, but not mixing D) Mixing and evaporation but not the complete combustion of the propellants
 
Answer & Explanation Answer: A) Mixing, evaporation and complete combustion of the propellants

Explanation: All the three factors – mixing, complete combustion and evaporation of the propellants are considered for the choice of the volume of combustion chamber. It is chosen such that the mixing is good, evaporation is less and the complete combustion is ensured at all times.

Q:

What is the range of temperature of reaction product gases in a rocket engine?

A) 500 to 1700 °C B) 1700 to 2500 °C
C) 2500 to 4100 °C D) 4100 to 6900 °C
 
Answer & Explanation Answer: C) 2500 to 4100 °C

Explanation: The temperature at which product gases of the chemical reaction taking place within the combustion chamber is too high. It is even higher than the melting point of some of the more commonly used materials in aircraft industry like aluminum (660 °C). Appropriate cooling mechanisms are set up to ensure that this high temperature doesn’t transfer over to the rocket components and that it doesn’t lead to the development of thermal stresses.
