Development of a Continuous Mode Sequencing Concept for Ejection Seats.
Abstract
The need to provide safe egress from aircraft during low altitude, high speed and adverse attitude ejections requires the development of highly sophisticated and complex escape systems. Traditionally, the operation of an ejection seat has relied on the functioning of pyrotechnic and mechanical devices which are activated based almost exclusively on timing considerations alone, with little or no inputs from actual environmental conditions. In order to provide greater ejection seat performance it is desirable to activate these devices based on accurate and comprehensive environmental data. This report presents an ejection seat event sequencing concept whereby seat subsystems are activated and deployed based on a detailed analysis of airspeed and altitude at the time of ejection. The analysis of this concept and the results of a computer study undertaken to estimate the possible performance improvements offered by this concept will also be presented.
