In order to launch satellites into a fixed orbit at a reasonable price, the ISRO successfully tested reliable next-generation air-breathing scramjet engines.
Jet engine
- A jet engine is a device that produces a strong pushing force known as thrust out of liquid fuel that is high in energy.
- A plane is propelled forward by the thrust from one or more engines, pushing air past its aerodynamically formed wings to produce lift, which propels it into the air.
Ramjet vs. Scramjet Engine
- Ramjet and scramjet are both varieties of jet engines.
- Ramjets are air-breathing jet engines that are frequently used for supersonic travel.
- Ramjets are unable to start at zero velocity and cannot produce thrust because there is not enough airspeed. Ramjets can only start at supersonic speeds.
- Therefore, it requires assisted takeoff aircraft or rockets to drive it to supersonic speeds, from where it begins to produce thrust.
- Ramjet engines can accelerate to speeds of roughly Mach 6, which limits their efficiency to supersonic travel.
- Over the years, Ramjet has transformed both rocket propulsion and missile technology.
Scramjet: What is the difference
- The Scramjet, also known as the Supersonic Combustion Ramjet, is a more intricate design that operates effectively at hypersonic speeds, often above Mach 6.
- Since the air entering is already at a high pressure, they don’t have any moving parts to compress the air.
- Scramjets operate very similarly to ramjets, with the exception that combustion also occurs at supersonic speeds.
This indicates that as pressurised air enters the combustion chamber, it does not slow do
