Abstract

Instead of cooling the turbine disk blades of the gas turbine engines using a very stressful and expensive method of stealing from the compressor air at a temperature of 650 degrees Celsius, it is possible to provide a much effective cooling by using fan stages (1) located on a second shaft (2) added to the entry point of the engine main shaft (5), which allows the cooling of HPT (8) and LPT (9) disks and blades (12,13) with air so much cooler than the air provided in the conventional method.
