Abstract
The US Navy along with Textron Marine & Land Systems (TM&LS) is qualifying and field testing the ETF40B gas turbine engine along with Full Authority Digital Engine Control (FADEC) system as possible upgrades to the current TF40B engine and analog control system currently installed on the Landing Craft Air Cushion (LCAC). The ETF40B engine and FADEC control system are of interest due to: increased power, proposed increase in Mean Time Between Overhauls (MTBO), and proposed increase in engine reliability. The primary topics presented in this paper are: 1. The design, development, and qualification of the ETF40B engine and FADEC control system 2. Integration of the ETF40B engine and FADEC into the LCAC 3. Field test data from two LCACs, follow-up testing and implementation
