Abstract
An engine control device may comprise a processor and a memory. The engine control device may be configured to modify a fuel flow based on a density of the fuel proximate a fuel nozzle. The engine control device may include a densimeter embedded in, or disposed proximate, the engine control device. The engine control device may include a temperature sensor embedded in, or disposed proximate, the engine control device. The engine control device may be electrically coupled to a fuel valve and/or configured to modulate the fuel valve based on a density of the fuel at the fuel valve.
Claims8
A fuel flow control system for a gas turbine engine, the fuel flow control system comprising:
- a fuel supply;
- a first fluid conduit in fluid communication with the fuel supply;
- an engine control device in fluid communication with the fuel supply via the first fluid conduit, the first fluid conduit extending from the fuel supply to the engine control device;
- a densimeter directly and operably coupled to the first fluid conduit;
- a first temperature sensor directly and operably coupled to the first fluid conduit;
- a fuel nozzle in fluid communication with the fuel supply;
- a second temperature sensor disposed between the fuel nozzle and the fuel supply;
- and
- a second fluid conduit, wherein:
- the fuel supply includes a first outlet and a second outlet,
- the first fluid conduit extends from the first outlet of the fuel supply to the engine control device,
- the second fluid conduit extends from the second outlet of the fuel supply to the fuel nozzle.
