Abstract
Oleophobic and/or oleophilic coatings to reduce heat loads on a gas turbine engine thermal management system are disclosed herein. An example method to reduce heat load in a gas turbine engine, the method including applying an oleophobic coating to an internal wall of a sump, the sump located in proximity to a heat generating element of the gas turbine engine, and applying an oleophilic coating to the heat generating element of the gas turbine engine.
Claims19
A method to reduce heat load in a gas turbine engine, the method comprising:
- applying an oleophobic coating to an internal wall of a sump, the sump located in proximity to a heat generating element of the gas turbine engine;
- and
- applying an oleophilic coating to the heat generating element of the gas turbine engine.
A sump of a gas turbine engine, the sump comprising:
- a heat generating element and an internal wall of the sump forming a first cavity, the heat generating element including an oleophilic coating, wherein an oleophobic coating applied to the internal wall of the sump includes a low heat transfer coefficient.
A sump system of a gas turbine engine, the sump system comprising:
- an oleophilic coating applied to a heat generating element of the sump system;
- and
- an oleophobic coating applied to an internal wall of a sump surrounding the heat generating element.
