Question

Consider the following statements with reference to Scramjet Engine:

1. Recently, DRDO successfully tested a scramjet combustor for 120 seconds, a significant achievement in hypersonic missile development.

2. Endothermic fuels used in scramjet engines help cool the engine and improve ignition.

3. Scramjet engines are more efficient than traditional jet engines at hypersonic speeds.

How many of the above statement is/are correct?

The correct answer is

All three

Why in the News?

"Indian Scientists Achieve Major Milestone in Hypersonic Missile Development”

Statement 1 is correct

DRDO's 120-second scramjet combustor test marks a significant advancement in India's hypersonic missile development program. This successful trial demonstrates crucial progress in mastering this cutting-edge propulsion technology.

Statement 2 is correct

Endothermic fuels play a vital role in scramjet engines by absorbing heat during combustion. This heat absorption helps to cool the engine's internal components, preventing excessive temperatures that could damage the engine. Additionally, these fuels can aid in the ignition process, enhancing the overall performance and reliability of the scramjet engine.

Statement 3 is correct

Scramjet engines offer superior efficiency compared to traditional jet engines when operating at hypersonic speeds. This increased efficiency stems from their ability to utilize the ram pressure of the incoming air for compression, eliminating the need for heavy and complex rotating compressors found in conventional jet engines. This streamlined design results in significant fuel savings and improved performance at hypersonic velocities.
