Abstract: A vehicle power generation system including: a first solenoid spool valve; a second solenoid spool valve; a first poppet valve fluidly connected to a high pressure inlet; a second poppet valve fluidly connected to the first solenoid spool valve and the first poppet valve; a third poppet valve fluidly connected to the second solenoid spool valve, the first poppet valve, and an impulse turbine; and a fourth poppet valve fluidly connected to the second solenoid spool valve, the second poppet valve, and the impulse turbine.

Abstract: A method of forming a seal plate for sealing between two components of an assembly includes forming a plate element from a first material, the plate element including at least one seal groove receptive of a seal element and forming a seal element from a second material different from the first material by one or more additive manufacturing processes, the second material an elastomeric material of a selected durometer. The seal element is affixed to the plate element at the seal groove. A seal plate includes a plate element having one or more seal grooves receptive of a seal element, the plate element formed from a first material. A seal element is installed into the seal groove, the seal element formed from a second material different from the first material by one or more additive manufacturing processes, the second material an elastomeric material of a selected durometer.

Abstract: A turbine generator assembly includes a turbine drivably connected to an electrical generator. The turbine includes a propellant input and a spent propellant exhaust. The spent propellant exhaust is connected to an exhaust flow path. An electrical component is connected to an output of the electrical generator such that the electrical component is powered by the electrical generator. A first heat exchanger including a cooling fluid inlet is connected to the exhaust flow path and a cooled feature is configured to be cooled by fluid received through the cooling fluid inlet. The cooled feature is at least a portion of the electrical component.

Abstract: A system and method includes a thrust system; a generator for providing electric power to at least one electromechanical actuator of the thrust system; a turbine for driving the generator; a speed control valve for metering propellant to the turbine; and a gear assembly for connecting the turbine, the generator, and the speed control valve.

Abstract: An oil cooling arrangement includes a first manifold and a second manifold, each configured to route an oil. Further included is a first tube having a first end proximate the first manifold and a second end proximate the second manifold, wherein the first tube is configured to receive the oil and route the oil toward the second manifold. Yet further included is a second tube having a third end proximate the second manifold and a fourth end proximate the first manifold, wherein the second tube is configured to route the oil from the second manifold toward the first manifold. Also included is a turbine exhaust path configured to route an exhaust flow, wherein the first tube and the second tube are disposed along the turbine exhaust path, wherein the oil is cooled upon passage of the exhaust flow over the first tube and the second tube.
