Why are Concorde engines Square?

Why are Concorde engines Square?

The air in-take is rectangular in cross section and is of variable geometry in that it embodies two moving ramps in the top surface, the ramps forward and aft, which do not meet, but move up and down to control airflow.

Why are supersonic inlets Square?

Seems like an odd choice of shape. Square intakes are designed to create oblique shock waves at combustion inlets, No. Supersonic intakes use oblique shock waves to decelerate the airflow to a subsonic condition before compressor entry to prevent compressor stall.

Did the Concorde have afterburners?

The Concorde’s engines used afterburners to gain additional thrust to reach supersonic speeds. Afterburners mix additional fuel with the exhaust gases from the primary combustion chamber and burn it to get more thrust. Afterburners are typically used on supersonic military jets.

Did Concorde have reheat?

According to John Britton the Concorde was the only aircraft that was ever certificated with reheat that boost the thrust up to accelerate it transonic to Mach 1. It took the Bristol Aircraft Corporation more than a decade to get to that stage.

What is the most powerful aircraft engine?

GE9X engine
The GE9X engine for the Boeing 777X has been recognized by the Guinness Book of World Records as the the most powerful commercial aircraft jet engine (test performance) after reaching 134,300 lbs of thrust.

What is the purpose of inlet in gas turbine engine?

All turbine engines have an inlet to bring free stream air into the engine. The inlet sits upstream of the compressor and, while the inlet does no work on the flow, inlet performance has a strong influence on engine net thrust.

What is the purpose of air inlet?

The inlet functions to capture and decelerate air prior to entry into the compressor. While the inlet is often optimized for cruising conditions, it must provide adequate massflow during all other engine operating conditions including takeoff, landing, and maneuvering.

Why is it called Afterburner?

An afterburner (or reheat in British English) is an additional combustion component used on some jet engines, mostly those on military supersonic aircraft. Afterburning injects additional fuel into a combustor in the jet pipe behind (i.e., “after”) the turbine, “reheating” the exhaust gas.

What would happen to Concorde if it went supersonic?

If this happens to Concorde during supersonic speeds, it could theoretically caused a catastrophic failure of the airframe altogether. The most difficult case of change in demand would be if an engine was to fail during the flight, or shut-down at high speed. Suddenly, the engine would require little or no air.

Why did Concorde have two doors on her engine?

While Concorde is travelling at slow speeds all the air and which is required goes into her engines and is known as primary airflow, this means that they would keep the secondary doors closed during this time. This also stops the engine from ingesting any of its own exhaust gases

How many Concorde’s actually went into service?

Only 14 of the aircraft actually went into service. Concorde supersonic passenger transport, which first flew in 1969 and entered commercial service in 1976. British Aircraft Corporation and Aérospatiale of France built the airframe, which was powered by four Rolls-Royce/SNECMA engines. © Senohrabek/Dreamstime.com

Why didn’t Concorde fly in the Middle East?

This was in the days before much middle eastern airline traffic, it wasn’t worth flying Concorde on a route shorter than 3 hours, and Concorde did not, as already stated, have ultra long distance range, so no airline would have bothered operating Concorde on such flights. These bans were symbolic, the USA ban was a serious blow.
