Title: The Innovative Mind of Matthew P Mitchell
Introduction
Matthew P Mitchell is a prominent inventor based in Berkeley, CA. He has made significant contributions to the field of engineering, particularly in the development of advanced airship technologies. With a total of 15 patents to his name, Mitchell's work showcases his innovative spirit and dedication to solving complex problems.
Latest Patents
One of Mitchell's latest patents is for a high-altitude long-endurance airship. This airship features a top surface that is highly emissive of infrared radiation and a bottom surface that is highly absorptive of infrared radiation. Movable displacer blankets inside the airship separate the upper and lower portions, allowing for efficient thermal management. The lifting gas within the airship is warmed by radiation from the earth when the displacer blankets are in their upper position, and cooled by radiation to space when in the lower position. This design enables the airship to function as a heat engine, recovering net power output in the form of electric power. The overall configuration of the airship is a variable-thickness flying wing, which allows for gliding flight through the alternation of expansion and compression.
Another notable patent involves a cooling load enclosed in a pulse tube cooler. In this design, the cooling load is contained within the envelope of the pressure vessel that holds the working fluid. Flow-smoothing means, such as stacked screens and perforated plates, help to spread the flow of fluid entering the cold end of the pulse tube, enhancing the efficiency of the cooling process.
