SPACE TECHNOLOGY

Rocket Propulsion ISRO Propulsion Complex

A single decision in 2014 transformed India's rocket propulsion testing landscape forever

0

What was the primary reason for elevating the ISRO Propulsion Complex to an independent centre in 2014?

To reduce the number of ISRO centres and consolidate operations To shift focus from propulsion to satellite manufacturing To specialize and enhance testing and integration of propulsion systems for increasingly complex space missions

AEROSPACE ENGINEERING

Rocket Propulsion Next Generation Launch Vehicle Engines

India's Next Generation Launch Vehicle engines aim for partial reusability to cut space mission costs

0

What is the primary advantage of the Next Generation Launch Vehicle's engine design compared to previous ISRO launch vehicles?

They use solid propellants exclusively for higher thrust. They enable partial reusability, improving cost efficiency and launch frequency. They are designed only for small satellite launches, reducing complexity.

Rocket Propulsion Chemical Rocket Engine

Chemical rockets carry their own oxidizer to operate in the vacuum of space and achieve escape velocity

0

Why do chemical rocket engines carry their own oxidizer instead of relying on atmospheric oxygen?

Because they need to operate in the vacuum of space where there is no atmospheric oxygen Because carrying oxidizer increases the rocket's speed beyond escape velocity Because atmospheric oxygen is too reactive to be used safely in rocket combustion

Spacecraft Propulsion Rocket Propulsion

Rocket propulsion harnesses Newton's third law to power spacecraft through the vacuum of space

0

Why is rocket propulsion effective in the vacuum of space, unlike conventional aircraft propulsion?

Because it uses air from space to generate lift and thrust Because it expels mass backward to produce thrust without needing air to push against Because it relies on magnetic fields in space to propel the spacecraft
