Abstract: A fuel system includes a fuel tank that stores fuel therein, and a fuel cooling system. The fuel cooling system includes a fuel cooling system fuel line in fluid communication with the fuel tank, one or more fuel cooling system heat exchangers in fluid communication with the fuel cooling system fuel line, and a fuel cooling system fuel pump. The fuel cooling system fuel pump pumps the fuel from the fuel tank such that the fuel flows through the fuel cooling system fuel line and into the one or more fuel cooling system heat exchangers to absorb heat from one or more aircraft components to become heated fuel. The heated fuel is returned and stored in the fuel tank.

Abstract: A heat exchanger for a hydrogen fuel delivery system includes a tube bank including an inner-tube where a first portion of the inner-tube extends through an inlet region of the tube bank, a second portion of the inner-tube extends through a mid-region of the tube bank, and a third portion of the inner-tube extends through an outlet region of the tube bank. A thermal buffer at least partially surrounds the inner-tube. A first portion of the thermal buffer extends along the first portion of the inner-tube, a second portion of the thermal buffer extends along the second portion of the inner-tube, and a third portion of the thermal buffer extends along the third portion of the inner-tube. A plurality of fins is disposed along the inner-tube and extends radially outwardly from an outer surface of the thermal buffer.

Abstract: A system includes a hydrogen sensor configured to generate data indicative of a level of hydrogen present within the compartment and a computing system. The computing system configured to determine at least one of the level of hydrogen present within the compartment or a rate of change of the level of hydrogen present within the compartment and compare the determined at least one of the level of hydrogen present within the compartment or the rate of change of the level of hydrogen present within the compartment to an associated threshold value. Furthermore, when the determined at least one of the level of hydrogen present within the compartment or the rate of change of the level of hydrogen present within the compartment exceeds the associated threshold value, the computing system is configured to initiate a control action associated with reducing the level of hydrogen present within the compartment.

Abstract: An engine control system may be configured to perform a method of controlling thermal bias in a turbomachine. An exemplary method may include determining a thermal bias-value for the turbomachine, and performing a cooling treatment based at least in part on the thermal bias-value. The thermal bias-value may include a difference between an upward temperature-value corresponding to a first one or more temperature measurements of an upward portion of the turbomachine and a downward temperature-value corresponding to a second one or more temperature measurements of a downward portion of the turbomachine. The cooling treatment may include at least one of: circulating air through at least a portion of the turbomachine, and rotating a shaft of the turbomachine with a motoring system.

Abstract: A gas turbine engine is provided having: a turbomachine; a fan section having a fan rotatable by the turbomachine; a nacelle enclosing the fan; and an engine controller positioned within the nacelle. The nacelle defines an inner surface radius (r) along the radial direction inward of the engine controller, wherein the engine controller defines a radial height (Δr) along the radial direction, a total volume (V), and a normalized radius (r′). The normalized radius (r′) is a ratio of the inner surface radius (r) to the total volume (V) to cube root, and wherein these parameters are related by the following equation: 0.1(r′)−1
