Abstract: Methods, devices, and systems are described for a system including a concentrated light source configured to focus light energy along a line of focus and a moving platform configured to face the concentrated light source and suspend a reactants mixture. The system also includes a controller coupled to the concentrated light source and the moving platform. The controller is configured to drive the moving platform at a first speed and a second speed. Suspending the reactants mixture within the line of focus of the concentrated light source as the moving platform is driven at the first speed converts the reactants mixture to slag. Suspending the reactants mixture as the moving platform is driven at the second speed does not convert the reactants mixture to slag.

Abstract: Methods, devices, and systems are described for a system including a rotation motor configured to rotate a valve seal holder, the valve seal holder having at least one pass-through interface and closed-off interface, a camshaft coupled to the valve seal holder, and a controller communicatively coupled to the rotation motor and the camshaft. The controller is configured to separate at least one of the pass-through interface or the closed-off interface of the valve seal holder from the seat configured to interface with the external system. The controller is configured to rotate, using the rotation motor, the valve seal holder until at least one of the pass-through interface or the closed-off interface is aligned with the seat. The controller is configured to compress the at least one of the pass-through interface or the closed-off interface against the seat to create a seal over the seat.

Abstract: A system includes a plurality of sensors, a controller and a component. The plurality of sensors are configured to obtain sensed data indicative of characteristics of an environment. The controller is configured with a reduced order model to output a predicted parameter based on the sensed data. The reduced order model is generated on an external computer system using a high-fidelity physics-based model. The controller is configured to control the component based on the predicted parameter.

Abstract: A method and system for predicting heat exchanger blockage in an aircraft is provided. The method includes generating a reduced order model (ROM) that predicts a ram air fan (RAF) surge margin that correlates to a heat exchanger blockage parameter, calculating, using the ROM, a predicted RAF surge margin value using a sensor signal received from a sensor connected to a ram air fan (RAF), calculating the heat exchanger blockage parameter using at least the predicted RAF surge margin value, and reporting, to a user, the heat exchanger blockage parameter that indicates when a heat exchanger blockage condition is present.

Abstract: A computer implemented method to determine aircraft sensor failure and correct aircraft sensor measurement in an aircraft system is provide. The computer implemented method includes determining, using a physics-based high-fidelity model, a high-fidelity system response over operating conditions during which sensor drift of a sensor of interest can be detected, creating, using an aircraft system controller, a reduced order model (ROM) using the high-fidelity system response, wherein the ROM correlates with the sensor of interest when operating normally, calculating, using the ROM, at least one reduced order sensor value, determining an error value between the reduced order sensor value and a sensor measurement reading from the sensor of interest, and comparing the error value to an error threshold, wherein the sensor of interest has failed when the error value is greater than the error threshold.
