Can a turbofan engine have an afterburner?
A turbojet engine equipped with an afterburner is called an “afterburning turbojet”, whereas a turbofan engine similarly equipped is sometimes called an “augmented turbofan”. A “dump-and-burn” is an airshow display feature where fuel is jettisoned, then intentionally ignited using the afterburner.
How does a ramjet start?
ramjet, air-breathing jet engine that operates with no major moving parts. It relies on the craft’s forward motion to draw in air and on a specially shaped intake passage to compress the air for combustion. After fuel sprayed into the engine has been ignited, combustion is self-sustaining.
Are scramjets efficient?
Because the scramjet uses external air for combustion, it is a more efficient propulsion system for flight within the atmosphere than a rocket, which must carry all of its oxygen.
Do fighter jets use turbofan engines?
The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion. Most commercial aviation jet engines in use today are of the high-bypass type, and most modern military fighter engines are low-bypass.
Could the Concorde break the sound barrier?
The last flight of a Concorde in service was in 2003. Although Concorde and the Tu-144 were the first aircraft to carry commercial passengers at supersonic speeds, they were not the first or only commercial airliners to break the sound barrier.
What is the difference between a turbojet and a ramjet engine?
Turbo props are more efficient and practical for many slower speed applications. Ramjet: Just like a turbojet, except instead of a mechanical compressor, a scoop is used to compress “ram air” air being scooped up by the engine. Like all other engines so far, ramjets combust fuel-air mixture at subsonic speed, even if the aircraft is supersonic.
What is a turbofan engine?
A turbofan is the turducken of engines — essentially a turbojet wrapped in a larger cowling with a big fan slapped on its front. The fan pulls in more air, which the engine then splits into two streams: Some air moves through the nested turbojet, while the rest flows through the empty space around it.
Did the comet have turbofan engines?
The de Havilland Comet had turbojet engines integrated into its wings, such that its nacelles were mostly flush with the wings like so: (wikimedia.org) I recognize that turbofan engines are Stack Exchange Network
What happens when fluid hits a ramjet engine?
NASA engineer Laura O’Connor inspects a supersonic ramjet (scramjet) engine model at Langley Research Center in Hampton, Virginia. As anyone who’s ever belly flopped off a high dive can tell you, when you hit a fluid without giving it time to get out of the way, it tends to hit back.
