development

LHTEC is a joint venture formed in 1984 by the US company Garrett AiResearch and Allison Engine Company (now Honeywell International and Rolls-Royce ) to develop an engine for the Boeing-Sikorsky RAH-66 (Comanche helicopter). On the T800, the high-pressure core comes from Honeywell and the low-pressure part from Rolls-Royce. The engine is equipped with a FADEC system and is used on the AgustaWestland AW159 , RAH-66 Comanche (T800-801) and AgustaWestland T-129 . The variant CTS800-4 (or also T800-4) is a variant presented in September 2001 with increased performance compared to the basic model. The approval for this engine was granted in November 2003. The Westland Lynx , the Agusta A129 , Japan's ShinMaywa US-1A Kai , the Ayres LM200 Loadmaster and the Sikorsky X2 are to be equipped with it.

Technical specifications

The twin-shaft engine consists of an annular air inlet with an integrated active particle separator, a two-stage radial compressor (each a one-piece impeller made from a titanium alloy), an annular combustion chamber and a two-stage axial turbine for the compressor and the free-running working shaft . The output shaft is equipped with a reduction gear.
