What is a gas turbine and how does it work?

What is the speed of a gas turbine? The speed of a gas turbine can vary depending on its design, size, and application. However, in general, gas turbines operate at high speeds, typically in the range of tens of thousands of revolutions per minute (RPM).

Which are typical rpm values for aeronautical turbines?

The high pressure compressor and turbines of an airliner engine will run at above ten thousand RPM, while the propeller of a large turboprop engine wants to run at about 1700 to 2200 RPM, and in case of the NK-12 of the Tu-95 the propellers run at only 750 RPM. Both the fan and the propeller are powered by separate low pressure turbines.

Turbo Tips: Practical Notes & Useful Guidelines on Modern Gas

The smaller the gas turbine, the higher the rotating speed of the shaft(s) required to maintain the tip speed. The blade-tip speed determines the maximum pressure ratios obtained by the turbine and air compressor. This, in turn, limits the maximum power and efficiency obtained by the gas turbine. For example, medium-sized gas turbines (5
