Question 1 of 5
1. Question
1 pointsWith reference to Scramjet technology, consider the following statements:
1. The scramjets are a variant of a category of jet engines called the air-breathing engines which uses no fuels.
2. Scramjet engines work efficiently at hypersonic speed.Which of the statement given above is/are correct?
Correct
Explanation:
Ramjet V. Scramjet
A ramjet is a form of air-breathing jet engine that uses the vehicle’s forward motion to compress incoming air for combustion without a rotating compressor.
Fuel is injected in the combustion chamber where it mixes with the hot compressed air and ignites.
A ramjet-powered vehicle requires an assisted take-off like a rocket assist to accelerate it to a speed where it begins to produce thrust.
Ramjets work most efficiently at supersonic speeds around Mach 3 (three times the speed of sound) and can operate up to speeds of Mach 6.
However, the ramjet efficiency starts to drop when the vehicle reaches hypersonic speeds.
A scramjet engine is an improvement over the ramjet engine as it efficiently operates at hypersonic speeds and allows supersonic combustion. Thus it is known as Supersonic Combustion Ramjet or ScramjetIncorrect
