A system for fluid temperature control and actuation control for an aircraft engine fueled by dual fuels. The system includes a first fuel system having a first fuel tank fluidly coupled to the engine, a second fuel system having a second fuel tank fluidly coupled to the engine, with the second fuel being different from the first fuel and having a different temperature than the first fuel, a fuel distribution unit (FDU) fluidly coupled to the first fuel tank of the first fuel system, and a fuel-to-fuel cooler (FFC) configured to transfer heat between the first fuel in the first fuel system and the second fuel in the second fuel system.

System for temperature and actuation control and method of controlling fluid temperatures in an aircraft

The invention concerns a starting system for a gas turbine aircraft engine which automatically controls the sequencing of events needed during engine startup. The control schedules fuel in a manner which avoids stalls, and, further, takes corrective actions when stalls occur, both on the ground and in the air. The control detects failures in the starter energy source, which can cause an abortive start and damaging temperatures. The control also provides unique scheduling of fuel in severely cold conditions.
