Title: Peter J. Louden and His Aircraft Safety Patents.

Introduction

Peter J. Louden is an inventor associated with Mercer Island, Washington, and The Boeing Company. His work includes aircraft technologies focused on fire containment and engine-condition warnings. He holds 4 patents.

Latest Patents

Louden’s listed patents include “Aircraft Labyrinth Fire Seal,” which describes a fire-sealing arrangement for an aircraft propulsion system. Overlapping upper and lower plate rows form a labyrinth path intended to impede flame passage. The design also includes a pressure-equalization mechanism and endplates positioned along the assembly. The patent describes a method for fire-sealing a propulsion-system fire zone by controlling pressure across the seal.

Another listed invention, “Abnormal Start Advisory System (ASAS) for Aircraft Engines,” concerns a flight-deck warning system. It alerts the flight crew to abnormal engine operating conditions in the sub-idle region, using signals related to exhaust temperature, core rotor speed, total air temperature, fuel flow, and calibrated airspeed.

Career Highlights

Louden’s patent work reflects an emphasis on aircraft propulsion safety and operational awareness. The fire-seal invention addresses flame containment, while the advisory system is designed to help crews recognize abnormal engine starts.

Collaborations

Louden’s listed coworkers include fellow inventors James T. Giffin and Malcolm L. Olthouse. His work is associated with The Boeing Company.

Conclusion

Peter J. Louden’s inventions address two important aspects of aircraft safety: limiting the spread of fire around propulsion systems and alerting flight crews to abnormal engine conditions.
