Advancements in the field of manned recovery systems indicate that it is now possible to reduce the present casualty rate associated with the emergency ejection of man from aircraft. This may be accomplished by the use of an advanced mode of recovery called the Jetcone. This is a high-drag device consisting of a gas inflatable fabric structure which is cone shaped to achieve aerodynamic stability. Locating the man within the inflated structure and integrating a shock attenuation system into the nose of the vehicle provide a high degree of protection upon impact. This paper describes the Jetcone configuration and defines the design parameters affecting man, aircraft, and recovery vehicle. Operational and design features of the system are presented. A comparison of the Jetcone system and a parachute system are presented in terms of weight, size, packaging, and reliability. It will be shown that this system improves man's chance for survival, yet remains simple, lightweight, and reliable.

A comprehensive group of appropriate open ejection seats, encapsulated ejection seats, cockpit pod capsules, separable nose capsules, and subsystems are described. The descriptions provide information on items such as initiation, crew positioning and restraint, emergency pressurization and oxygen, seat-man separation, capsule separation, rocket motors, rocket catapults, stabilization, deceleration, recovery parachute, landing impact attenuation, flotation, location aids, and survival equipment or provisions. Information is also provided on escape system performance, tests, accelerations experienced, stability characteristics, trajectories, escape time sequence, envelope dimensions, weights, production or development status, and projected system improvements.

A study of open seat aircraft emergency escape systems is presented. Special attention is directed toward thrust requirements necessary to achieve improved seat trajectories. A two-dimensional, three degrees-of-freedom mathematical model of a rocket-powered ejection seat trajectory, including means of attitude stabilization, has been formulated. This resulting mathematical model has been programmed on both a digital computer and an analog computer. On the basis of available aerodynamic and trajectory data, a representative ejection seat configuration was selected for study. Typical trajectories were computed using the mathematical model. Parametric studies directed toward providing a guide for achieving improved escape trajectories were conducted and summarizing graphs are presented. These parameters include aircraft velocity, aircraft pitch angle, main rocket size, vernier rocket thrust, and thrust misalignment.
