Title: Brian Joseph Petersen and His Jet Engine Innovations.

Introduction

Brian Joseph Petersen is an inventor based in Mason, Ohio, whose patent work focuses on aircraft engine exhaust systems. He is associated with General Electric Company and has 2 patents.

Latest Patents

Petersen’s listed patents address ways to manage airflow and exhaust in variable-cycle jet engines.

- **Secondary nozzle for jet engine.** This invention routes a third stream of air through a separate nozzle concentric with the primary engine nozzle. The third stream is exhausted near the interface between the aircraft airframe and the engine’s outer flaps, where it can reduce a low-pressure recirculation zone and associated boat-tail drag. The design aims to improve engine efficiency while allowing the third stream’s exhaust to contribute to aircraft thrust.

- **Multi-nozzle flow diverter for jet engine.** This exhaust system combines a core exhaust with a convergent-divergent nozzle and a duct for a third stream of air. Depending on flight mode, a diverter valve directs the third stream through a secondary nozzle, divergent slots in the core nozzle, or both. This arrangement provides selectable control of the engine’s exhaust flow.

Career Highlights

Petersen’s patent portfolio reflects work on aircraft propulsion, particularly the design and control of multiple exhaust streams. His inventions describe approaches to reducing aerodynamic losses and adapting engine exhaust configurations to different flight conditions.
