# Your question: How fast does a 747 engine spin?

Contents

## How fast does a jet engine spin?

At full power the blades of a typical commercial jet compressor rotate at 1000mph (1600kph) and take in 2600lb (1200kg) of air per second.

## Can a 747 spin?

Yes they will spin.

## What RPM does a plane engine spin at?

Most jet engines, main shaft, rotates about 13 to 15,000 RPM at full power during climbout. This is slowed down to 8,000 to 10,000 for cruising.

## How fast does a 777 engine spin?

On large modern airliners, the front fan runs at between 2500 and 4000 RPM. For comparison, the high-pressure compressor and turbine will run at more than 10.000 RPM.

Examples of Jet Engine RPM.

Engine Model RPM Application
General Electric GE90 2261 / 2355 RPM* Boeing 777
General Electric GE9X 2355 RPM Boeing 777X

## How fast does a 747 go when landing?

At cruising altitude, most commercial airplanes fly at a speed of roughly 500 to 600 mph. When landing, however, they must reduce their speed. A typical 747, for instance, has a landing speed of about 160 to 170 mph. And upon touching the runway, airplanes must quickly brake until they come to a complete stop.

## At what speed does a Boeing 737 land?

The average landing speed for a Boeing 737-800 with flaps deployed is about 145 knots, but this can be higher depending on the plane’s weight. The number of flaps deployed can also vary due to crosswinds and wind shear. When landing without flaps, the speed on a 737-800 is more like 200 knots.

## Can a 737 recover from a spin?

With it’s wings swept back it tends to enter a flat spin, from my training and studies, a flat spin is unrecoverable. However, FSX Boeing 737 has a hard time recovering from the stall warning.

## How do pilots recover from a flat spin?

The recovery procedure from a spin requires using rudder to stop the rotation, then elevator to reduce angle of attack to stop the stall, then pulling out of the dive without exceeding the maximum permitted airspeed (VNE) or maximum G loading.

## Do jet engines spin same direction?

On most twin or multi-engine propeller driven aircraft, the propellers all turn in the same direction, usually clockwise when viewed from the rear of the aircraft. In a counter-rotating installation, the propellers on the right wing turn counter-clockwise while those on the left wing turn clockwise.

## How fast do turbo fans spin?

Propeller engines are most efficient for low speeds, turbojet engines – for high speeds, and turbofan engines – between the two. Turbofans are the most efficient engines in the range of speeds from about 500 to 1,000 km/h (270 to 540 kn; 310 to 620 mph), the speed at which most commercial aircraft operate.

## How hot is jet exhaust?

Today’s commercial jet engines can reach temperatures as high as 1,700 degrees Celsius (that’s 3,092 degrees Fahrenheit) because of the highly effective thermal barrier coatings that line the inside of the chamber.
