Title: **W James Stone: Pioneering Ejection Systems for Enhanced Aircrew Safety**

Introduction

W James Stone, an innovative inventor based in China Lake, CA, has made significant contributions to aircraft safety with his impressive portfolio of ten patents. Working for the United States of America, as Represented by the Secretary of the Navy, Stone has developed groundbreaking technologies that enhance the survivability of aircrew during emergency ejections from inverted aircraft.

Latest Patents

Among his latest inventions are two notable patents that address critical challenges in aircrew ejection systems. The first, titled "Attitude Selective Aircrew Escape Control," introduces a line cutter or discharge valve that responds to the aircraft's attitude. This innovative mechanism is positioned on an aircraft ejection seat to interrupt the gas-initiated sustainer rocket system. During inverted ejections, the device effectively reduces crew member velocity toward the ground by preventing sustainer rocket ignition, thereby lengthening the time available for parachute deployment and improving safety.

The second patent, known as "Vertical Seeking Aircrew Escape System," focuses on ensuring safe ejection from inverted aircraft at low altitudes. This system features an aircraft ejection seat that actively seeks the upward vertical direction. An attitude control processor processes signals from three-axis attitude sensors, regulating hydraulic fluid flow via servo valves to hydraulic actuators connected to a spherical rocket motor mounted on a two-axis gimbal system.
