The T700 engine was originally designed in the 1970s; it has been decades since the Army designed a new centerline engine in this turboshaft class. (See Figure 1, Page 68.) “Certainly the technologies have increased tremendously since then,”       new design tools and technologies for    gas generator, and power turbine sec- tions, as well as improvements in inlet particle separators that remove sand and dust before it gets in the engine.”


The big performance advantage is in


high/hot conditions that characterize areas such as Afghanistan. At higher altitudes, the engine becomes a limiting factor. Therefore, even without chang- ing anything else, the ITEP engine will enable the pilot to have more lift at  not able to go using the current engine.
