Abstract
A hydraulic system for a hydrogen fueled gas turbine engine. The hydraulic system comprises a closed-loop hydraulic fluid conduit, a hydrogen-hydraulic fluid heat exchanger configured to exchange heat between cryogenic hydrogen fuel and hydraulic fluid within the hydraulic fluid conduit, and a second fuel-hydraulic heat exchanger configured to exchange heat between a second, non-hydrogen fuel and hydraulic fluid in the hydraulic fluid conduit.
Claims16
A hydraulic system for a hydrogen fueled gas turbine engine, the hydraulic system comprising:
- a closed-loop hydraulic fluid conduit;
- a hydrogen-hydraulic fluid heat exchanger configured to exchange heat between cryogenic hydrogen fuel and hydraulic fluid within the hydraulic fluid conduit;
- a second fuel-hydraulic heat exchanger configured to exchange heat between a second, non-hydrogen fuel and hydraulic fluid in the hydraulic fluid conduit;
- a hydrogen fuel circuit configured to flow the hydrogen fuel through the hydrogen-hydraulic fluid heat exchanger but not the second fuel-hydraulic heat exchanger;
- and
- a second fuel circuit configured to flow the non-hydrogen fuel through the second fuel-hydraulic heat exchanger but not the hydrogen-hydraulic fluid heat exchanger.
