What distinguishes scramjets from ramjets?
Understand the Problem
The question is asking to compare and contrast two types of air-breathing engines, scramjets and ramjets, specifically pointing out the fundamental differences between them based on their operational principles and speed requirements.
Answer
Scramjets are distinguished from ramjets by supersonic combustion.
The final answer is that scramjets are distinguished from ramjets because combustion occurs at supersonic air velocity inside the engine.
Answer for screen readers
The final answer is that scramjets are distinguished from ramjets because combustion occurs at supersonic air velocity inside the engine.
More Information
Scramjets can achieve higher speeds than ramjets, typically efficient at speeds above Mach 6, due to their ability to handle supersonic airflow.
Tips
A common mistake is confusing the operational speeds of the engines. Remember that ramjets work best at subsonic to low supersonic speeds (up to Mach 6), while scramjets excel beyond Mach 6.
