Abstract

Background: To date, there is no standard jettison mechanism for doors, windows, or hatches in ditched helicopters. A new Universal Escape Exit (UEE^™) has been invented and the performance has been compared with two current in-service systems in a helicopter underwater escape trainer. Method: A total of 416 evacuations were conducted by 40 subjects in two experiments using the Survival Systems Limited's underwater escape trainer. Results: The UEE^™ had a distinct 2-s advantage to escape; and, in the majority of cases, was preferred to a rotating lever or a straight push out system. Conclusions: Further work should continue with UEE^™ development for qualification in an operational helicopter.

Keywords: helicopter, ditching, survival, cold water, breathholding, jettison, mechanisms.
