Multi-Axis Vibration Mitigation and Habitability Improvement for Seated Occupants
Agency / Branch:
DOD / NAVY
A continuous wave cushion with dynamic stiffness properties tuned to mitigate harmful/uncomfortable E-2C aircraft vibration is proposed as an innovative solution for improving pilot/operator ability to conduct long missions without numbness and pain in the back and legs. Review of literature pertinent to back pain associated with the E-2C and interviews with Navy physiologists familiar with the E-2C suggest that the main contributor to the back, neck, and leg pain is the duration of time for which aviators are seated. The proposed solution has been shown to dramatically improve circulation in body/seat contact areas where seated pressure can occlude normal capillary blood flow and induce pain. In addition to the vibration attenuation and circulatory enhancement that it will provide, it will also incorporate features for reducing body contact pressure points in the seat bottom and back cushions, relief of off-axis gravity forces that apply continuous lateral load to the aviator's body when flying nose-up, and improved support for aircrew arms and feet. The optimum embodiment of this novel cushion taking into account vibration, ergonomics, posture, weight, mission equipment, reliability, ease of implementation, and effectiveness will be defined by a design specification that will be developed early in Phase I.
