GE Aviation details T901-GE-900 testing
GE Aviation has successfully completed testing of its T901-GE-900 turboshaft engine prototype in support of the US Army’s Improved Turbine Engine Program (ITEP), the company announced on 9 October.
The tests validated the readiness of the engine for the ITEP engineering and manufacturing development (EMD) phase. The T901 engine tests were conducted for six months and verified growth margin to meet future ITEP power requirements.
The company has also run compressor, combustor and turbine component tests on the engine under its own internal development programme.
In 2016, the army awarded GE Aviation a $102 million, 24-month contract that will culminate in the upcoming T901 preliminary design review, after which the army plans to select a single supplier to complete the EMD phase of ITEP.
The T901 integrates the use of advanced manufacturing and high-temperature material technologies initially developed and matured for GE's commercial jet engines, such as ceramic matrix composites (CMC) and additive manufactured components in order to reduce fuel consumption and lower aircraft operating weight. CMCs enable less cooling air to be used to cool parts in the engine's hot section, thus improving engine efficiency.
