Energetic one way sequence termination valve

Abstract

A method of sequencing a pyrotechnic system includes igniting at least one of a first energetic coupled to a first inlet of a one way sequence termination arrangement, and a second energetic coupled to a second inlet of the one way sequence termination arrangement, fluidically coupling the first inlet to an outlet of the one way sequence termination arrangement in response to the second energetic being ignited before the first energetic is ignited, and blocking fluidic coupling between the second inlet and the outlet in response to the first energetic being ignited before the second energetic is ignited.

What is claimed is: 
     
       1. A method of sequencing a pyrotechnic system, comprising:
 igniting at least one of:
 a first energetic coupled to a first inlet of a one way sequence termination arrangement; and 
 a second energetic coupled to a second inlet of the one way sequence termination arrangement; 
 
 fluidically coupling the first inlet to an outlet of the one way sequence termination arrangement in response to the second energetic being ignited before the first energetic is ignited; and 
 blocking fluidic coupling between the second inlet and the outlet in response to the first energetic being ignited before the second energetic is ignited. 
 
     
     
       2. The method of  claim 1 , further comprising:
 moving, by a moveable shuttle, from a neutral position to at least one of a transferring position and a terminating position; 
 coupling the first inlet in fluid communication with the outlet of the one way sequence termination arrangement in response to the moveable shuttle moving to the transferring position; and 
 igniting a third energetic coupled to the outlet in response to the first energetic being ignited, 
 wherein the moveable shuttle moves to the transferring position in response to the second energetic igniting before the first energetic. 
 
     
     
       3. The method of  claim 2 , further comprising:
 preventing the outlet of the one way sequence termination arrangement from fluid communication with at least one of the first inlet and the second inlet in response to the moveable shuttle moving to the terminating position, 
 wherein the moveable shuttle moves to the terminating position in response to the first energetic igniting before the second energetic.
