Abstract
Propeller-driven aircraft produce vibrations that have a deleterious and potentially harmful effect to people exposed to their operational environment for extended durations. The E-2C aircraft has a high vibration environment, long duration missions, and a seat that produces impingements and"hot spots,"making the aircraft particularly dangerous and uncomfortable for occupants. A new propeller design has been marginally successful at reducing the blade passage frequency vibrations, but the propeller rotation frequency vibrations and seat comfort remain less than desirable. Previous studies have shown that incorporating various seat cushions has a beneficial effect at reducing seat vibrations in a single axis, but they have poor performance in multi-axis vibration environments. Safe, Inc. proposes a novel seat architecture that implements both passive and active components to achieve the desired multi-directional shock and vibration protection and the sought-after improvements in seat ergonomics. The proposed seat design will meet the requirements for all five seating positions of interest in E-2C. This Phase II effort will continue the efforts begun under Phase I funding.
