Junior Research Scientist Interview Questions and Answers

Solid fuel propulsion uses solid propellant while liquid fuel propulsion uses liquid propellant. Liquid fuel propulsion is more maneuverable.

• Solid fuel propulsion uses solid propellant, such as a mixture of fuel and oxidizer, which burns in a controlled manner to produce thrust.

• Liquid fuel propulsion uses liquid propellant, such as liquid hydrogen and liquid oxygen, which can be easily controlled and throttled for precise maneuvering.

• Solid fuel propulsion systems are generall...read more

Ram jet is a type of air-breathing jet engine while scram jet is a supersonic combustion ramjet engine.

• Ram jet operates at subsonic speeds while scram jet operates at supersonic speeds.

• Ram jet compresses air using the engine's forward motion while scram jet uses supersonic combustion to compress air.

• Scram jet is more efficient at high speeds compared to ram jet.

• Example: Ram jet is used in missiles like the BrahMos while scram jet is being developed for hypersonic aircraft.

Types of homing include visual, olfactory, magnetic, and celestial navigation.

• Visual homing involves using landmarks or familiar objects to navigate.

• Olfactory homing relies on sense of smell to find the way back to a location.

• Magnetic homing uses Earth's magnetic field for orientation and navigation.

• Celestial navigation involves using stars or other celestial bodies as reference points for direction.

• Advantages of homing include accuracy in returning to a specific location and...read more
