Thomas J Mueller

Title: Thomas J. Mueller and Rocket-Engine Innovation.

Introduction

Thomas J. Mueller is an inventor based in Long Beach, California. His patent work includes rocket-engine technologies focused on propellant injection, combustion, and turbine operation. He is credited with 7 patents.

Latest Patents

One of Mueller’s latest patents, “Pintle Injector Tip with Active Cooling,” describes a rocket-engine injector designed to mix two propellants while helping protect the injector tip from combustion heat. The design uses coaxial propellant passages and a pintle tip with chambers and apertures that direct propellant across the flow. This arrangement allows propellant moving through the tip to cool its downstream end wall during combustion. The patent also notes that the tip may be used to mix other liquids.

Another patent, “Pre-Burner for Low Temperature Turbine Applications,” describes a method for using concentrated hydrogen peroxide to drive a turbopump turbine. Fuel and hydrogen peroxide are received in a fuel-rich pre-burner and converted into fuel-rich gas, which then passes through the turbine. Operating the pre-burner at a low mixture ratio helps keep the turbine’s drive gas at moderate temperatures.

Career Highlights

Mueller’s disclosed inventions address challenges in rocket propulsion, including injector cooling and turbine operation. The patents illustrate approaches to managing heat and propellant flow in engine systems.
