Jet propulsion
Power through the ages
The forces associated with fluid movement are
well known; we are all familiar with the power
of strong winds, or waves crashing onto rocky
shorelines. However, the ingenuity of mankind has
enabled air and water flow, wind and wave energy
to be successfully harnessed, to provide beneficial
movement and power through the ages.
The gas turbine is a machine that burns fuel to provide
energy to create a moving flow of air, and to extract
valuable power or generate useful thrust from that
movement. The jet engine has revolutionised air
transport over the last 50 years, and Rolls-Royce has
been at the cutting edge, pioneering many of the key
advanced technologies of the jet age.
A jet engine employs Newton’s laws of motion to generate
force, or thrust as it is normally called in aircraft applications.
It does this by sucking in air slowly at the front, and then
blowing it out quickly at the back.
