Why do Russian jets have blue afterburners?

Why do Russian jets have blue afterburners?

In fact, as opposed to the orange plume you can observe on Western afterburners, Russian ones appear to be blue in color meaning that all the injected fuel is burnt before exiting the nozzle (the result of the engine design and the way fuel is dumped into the center of the cylinder): there is a more complete combustion …

Why is the afterburner blue?

The blue color is given by the characteristic EM radiation of C-H bond breaking, C- and H- radicals forming and recombining with O- radicals to form CO2 and H2O. This is independent of temperature and is the reason why a new gas oven’s flames are blue.

Why do afterburners have flames?

The idea behind an afterburner is to inject fuel directly into the exhaust stream and burn it using this remaining oxygen. This heats and expands the exhaust gases further, and can increase the thrust of a jet engine by 50% or more.

Does fire come out of Jets?

The flames that you see are from a process called reheating. It is a process in which fuel is introduced directly into the hot exhaust stream producing visible cones of flame and extra thrust. When you see a flame shooting out a jet’s nozzle it is because it has an after burner.

What does full military power mean?

Full military power allows the aircraft to regain enough power to get airborne. The pilot does a tremendous job of staying with the aircraft and maintaining controllability as it sinks well below the carrier flight deck.

What is the function of Afterburner?

An afterburner (or a reheat) is an additional component present on some jet engines, mostly military supersonic aircraft. Its purpose is to provide an increase in thrust, usually for supersonic flight, takeoff and for combat situations.

How long does Fighter jet fuel last?

In full afterburner at low altitudes, the F-16 can burn in excess of 64,000 pounds an hour. At full throttle, a U.S.-variant F-16 with maximum external fuel stores has about 20 minutes until it’s on emergency reserves (which would only last an extra minute or so at full afterburner).

Which is hotter a blue flame or an orange flame?

It full burner the mixture is quite rich, resulting in a orange colored flame. Lower stages of afterburner are probably much closer to peak stoichiometric mixture. Incidentally these blue colored flames are indicative of a much hotter exhaust gas temperature than an orange colored exhaust.

What causes the color of the exhaust gas?

The color of the exhaust gas is a function of the stoichiometric mixture of fuel and air ratio. It full burner the mixture is quite rich, resulting in a orange colored flame. Lower stages of afterburner are probably much closer to peak stoichiometric mixture.

Why are the flames of a gas oven blue?

The blue color is given by the characteristic EM radiation of C-H bond breaking, C- and H- radicals forming and recombining with O- radicals to form CO2 and H2O. This is independent of temperature and is the reason why a new gas oven’s flames are blue.

What makes a Sukhoi afterburner a blue color?

One of them said the blue color is the result of cold afterburner and Sukhoi afterburner design, the fuel being dumped at acute angles into the center of the cylinder using a few big injectors. It all depends. I don’t think there’s a distinctive color between the two.
