How fast do jet turbines spin
WebThe combustion system, typically made up of a ring of fuel injectors that inject a steady stream of fuel into combustion chambers where it mixes with the air. The mixture is burned at temperatures of more than 2000 degrees F. The combustion produces a high temperature, high pressure gas stream that enters and expands through the turbine … WebIt is typical for jet engines to operate between 8,000 and 9,350 RPM (high pressure compressor). What is the RPM of a gas turbine engine? For example, large jet engines operate around 10,000–25,000 rpm, while micro turbines spin as fast as 500,000 rpm. What is the highest RPM engine? Ranked: the highest-revving car engines ever made
