Title: Paul A. Galvan: Innovator in Spacecraft Maneuvering Systems
Introduction
Paul A. Galvan is a notable inventor based in San Jose, CA, who has made significant contributions to the field of spacecraft maneuvering systems. With a total of 2 patents to his name, Galvan's work focuses on enhancing the efficiency and functionality of solid-propellant systems.
Latest Patents
Galvan's latest patents include a "Solid-propellant-powered maneuvering system for spacecraft" and a "Dual pressure solid propellant control system." The first patent presents an improvement to a variable-pressure solid-propellant-powered maneuvering system, allowing it to operate for longer than one propellant burn time. This system features at least two solid propellant gas generators connected via a manifold to multiple nozzle valve clusters, with a sequence valve that isolates one generator until it is needed. The second patent describes a dual pressure solid propellant control system that operates at temperatures around 3000°F and at multiple pressures. This system utilizes a solid propellant gas generator connected to valve clusters by a manifold made of high-temperature material, with independently operable valves. A pressure feedback loop is implemented to maintain the system pressure at a commanded value by adjusting the gas exit area through varying the pulse duration modulation of the valves.
