The Forest Engineering Resarch institute of Canada (FERIC) surveyed off-highway, ground-based water delivery systems working in Alberta wildland fire operations to develop a recommended standard for these types of systems. This report contains information useful in the design and operation of mobile water delivery equipment in support of Alberta fire operations.
This study aimed to evaluate, in an accelerated manner, several aerodynamic drag reduction measures applicable to Class 8 tractor-trailer combinations. The tests were conducted according to SAE J1321 Joint TMC/SAE Fuel Consumption Test Procedure - Type II (SAE International 1986). The test results show up to 5% improvement in fuel consumption for the test vehicles equipped with boat tail devices, and up to 7% for the vehicles equipped with trailer skirts.
