Mustang Survival Corporation was contracted by DRDC-Toronto to design and construct modifications for the Forced Air Warmer (FAW) System that was delivered to fulfill a previous TIES tasking, W7711-8-7479-01/SRV, Order Number 7479-5. The intent of the FAW design modifications was to enhance the performance of the system, particularly with respect to airflow from the air distribution manifolds and leakage from the component interfaces. The following tasks were completed in order to meet the requirements of the tasking: -Redesigned the air distribution system, reducing the number of holes to 200 (89 Upper Manifold, 111 Lower Manifold), fitting each hole with a grommet and tested the system to meet the requirement for an average flow pressure of 2.2 to 2.5 in H2O; -Replaced fabric flow-dividing tunnel on the lower air distribution manifold with a 4-way rigid ABS connector; -Modified the Torso Dome, Suspension and Lower Insulation Blanket (LIB) components to implement Hook and Loop fastener attachment design for sealing the microenvironment against leakage; -Added Hook and Loop fastener to the Torso Dome foot end flap and to the passive Leg Insulation component to improve the interface.
