On take-off, at what speed does an aircraft engine fan turn?

Published on 20/08/2015 07:00 - By

An aircraft engine fan rotates at such a speed that it can suck in anything that approaches it. The fan is the part at the front of the engine, which can be seen when you board an airplane. It consists of a large number of blades (not rotors or propellers), which are the fan blades. To find out how fast a fan turns on take-off, we asked the engine manufacturer Snecma (Safran group). 

We then went to interview some of the passengers in an airport. The right answer is at the end of the video. The speed we provide in the video is for a CFM56.
