An impeller includes a cylindrical portion defining a fluid inlet, the cylindrical portion coaxial with a rotational axis of the impeller, a hub, a shroud extending downward and radially away from the cylindrical portion and covering the hub, a plurality of vanes extending between the shroud and the hub, a fluid outlet downstream of the plurality of vanes, a plurality of doors disposed circumferentially about the cylindrical portion proximate the inlet, and a spring element attached to and disposed between each of the plurality of doors and the cylindrical portion. Each of the plurality of doors is actuatable, via the spring element, between a first state and a second state.

An impeller includes a cylindrical portion defining a fluid inlet, the cylindrical portion coaxial with a rotational axis of the impeller, a hub, a shroud extending downward and radially away from the cylindrical portion and covering the hub, a first plurality of vanes extending between the shroud and the hub, and an extension portion disposed between the shroud and the hub and downstream of the first plurality of vanes. The extension portion includes an outer ring, and inner ring, and a second plurality of vanes extending between the outer ring and the inner ring.

A fuel control system for an aircraft includes first and second electric motor controlled fuel pumps connect in parallel with one another to a fuel line. A plurality of fuel nozzles are connected to the fuel line to issue pressurized fuel from the fuel line with the ability to throttle flow based on system needs along with the electric pumping. At least one fuel nozzle in the plurality of fuel nozzles includes a respective sensor system. A fuel controller is operatively connected to receive input from the respective sensor system of the at least one fuel nozzle, and operatively connected to control the first and second electric motor controlled pumps based on input from the respective sensor system of the at least one fuel nozzle.

An impeller includes a housing having a fluid inlet cavity defining a rotational axis. A plurality of vane are inlets arranged along an inner surface of the fluid inlet cavity and a plurality of vane outlets are circumferentially arranged along a rim of the housing. Each of the vane outlets is fluidly connected to a corresponding vane inlet by a corresponding internal channel situated internal to the housing. Each of the channels maintains a triangular cross-section from the vane inlet to the vane outlet.

Described is a system (and method) for training and using machine learning models to identify potential discrepancies between predicted odds and actual odds for a future event. The system may create a predicted odds machine learning model using an ensemble training algorithm. To create the risk management machine learning model, the system may determine a set of past odds differences between predicted odds outputted by the predicted odds machine learning model for past events and the actual historical odds for those past events. Once the predicted odds machine learning model and risk management machine learning model are trained, the system may use current (or real-time) event information to determine potential opportunities to leverage based on discrepancies between predicted odds of upcoming events and the actual odds for those events.

An impeller includes a body with an interior channel extending through the body along a centerline axis of the impeller. A plurality of blades is connected to the body on a forward end of the impeller centerline axis. The plurality of blades surrounds the interior channel and is fluidly connected to an array of inlets. An array of pentagonal channels extends through the body and radially outward in a spiral pattern. Each pentagonal channel is fluidly connected to a corresponding vane inlet and a corresponding pentagonal-shaped outlet. Each channel maintains a pentagonal cross-section shape from the inlet to the outlet. Each downward-sloping face of the cross section is more than 35 degrees from a horizontal plane perpendicular to the centerline axis of the impeller.
