When mentioning temperatures of turbine inlet area Dr. Aksit mentions Kelvin values of 1500 to near 1800.Wish TRMotor all the luck. They are aiming for a F110-GE-132 equivalent. With TEI+Tubitak-MAM+Gür metal they should be able to design and produce HPT blades withstanding at least 1400-1500 degrees continuously for an -129/132 equivalent. They managed 1300 degrees continuously with the TS1400 HPT blades, and are working on 1450 degrees if I am right.
As you would know -273.15 degrees Centigrade is 0 Kelvin.
So he is talking about 1525 degrees Centigrade at the upper end. The F110 engine’s specs give a turbine inlet temperature of 1510 degrees Celsius.
With jet propulsion the amount of thrust is directly proportional to the amount of heat that is exhausted from the nozzles. Therefore, the higher the temperature of the exhaust gas the higher the thrust achieved.
F110GE129 is a 29000lbf thrust engine. F110GE132 is a 32500lbf thrust engine. To achieve this extra thrust the latter could be working at higher temperature levels. It is 32kg heavier than the first one. It has a different bypass ratio and uses a different blisk fan.
Infact in tests f110GE129-EFE (Enhanced Fighter Engine) aka f110GE132, has managed to develop 34000lbf thrust. As stated;
“The EFE has been developed using low-risk derivative engine technology. It features a new increased airflow, high efficiency, three-stage long chord blisk fan, and an advanced radial augmentor that reduces complexity, improves maintainability, and provides increased parts life.”
If our indigenous engine is going to be in a way, an approximate copy of this engine, then we have a good powerful and dependable engine coming.
Having the capability to service both these engines and having infact done it many times over gives Tusas a unique perspective and possibility to achieve the goals they have envisaged.
