Title: William Alexander Dean and Aircraft Emergency Descent Technology.

Introduction

William Alexander Dean is an inventor associated with Parkville, Maryland. His patent work addresses aircraft safety, focusing on how an aircraft can descend in a controlled manner after a rotor assembly fails.

Latest Patents

Dean is credited with 1 patent: “Aircraft Emergency Descent System and Method.” The invention describes a failure procedure that monitors rotor assemblies, detects a rotor failure, and increases the torque supplied to functioning rotor motors to raise their rotational velocity. The system then regulates rotor speed by adjusting motor torque or collective blade pitch while monitoring the aircraft’s altitude. At a preset altitude, it adjusts the collective blade pitch to conserve momentum and reduce the aircraft’s descent rate as it approaches the ground.

Career Highlights

Dean’s listed patent reflects work on emergency descent control for rotorcraft. The method combines failure detection, rotor-speed regulation, and altitude-based blade-pitch adjustment to manage an aircraft’s descent following a rotor failure.

Collaborations

The provided information associates Dean with Textron Aviation Inc. and identifies Steven G. Hagerott as a coworker. These details offer context for his professional connections, though no specific roles in developing the patent are provided.

Conclusion

William Alexander Dean’s patent focuses on coordinating rotor control and aircraft altitude to help reduce descent speed during an emergency, highlighting a practical approach to rotorcraft safety.
