DescriptionA successful engine must demonstrate the following: WHILE OPERATING ON STANDARD JET A FUEL ... Complete two run profiles of several hours each on an Air Force engine test stand IN THE 100 bhp (74.57 kW) CLASS ... 50 bhp < max continuous output < 150 bhp (37.3 kW < max continuous output < 112 kW) WITH A POWER-TO-WEIGHT RATIO ≥ 2.0 bhp/lb(wet installed weight) (3.29 kW/kg(wet installed weight)) DEMONSTRATE A BRAKE-SPECIFIC FUEL CONSUMPTION (BSFC) OF 0.5 lbmfuel/bhp-hr (0.3kgfuel/kW) or lower, at max continuous power and, 0.59 lbmfuel/bhp-hr (0.36 kgfuel/kW) or lower, at 50% of max continuous power Corrections will be applied to compensate for variability in ambient conditions during testing. The official test procedures and Prize guidelines will include additional details and clarification of Prize requirements and how those performance standards will be measured.
