These briefing charts show the definition of the propulsion system for military applications, advanced integrated propulsion system (AIPS) power pack, assessment of the overall system power density potential: cooling system and parasitic fan power sizing, inlet and exhaust system impact, mission fuel determination and propulsion system volume estimates.
Past experience has shown that the power density of an engine itself is not a sufficient guide to determine whether it will meet the power density needs of the intended combat vehicle application. The real need is for the complete propulsion system to be power dense. Here the definition of the propulsion system includes the engine, transmission, cooling system, air filtration system, intake and exhaust ducting, controls, accessories, batteries, fuel ...
A method for indirectly determining the laminar flame speed for diesel fuel was formulated and benchmarked against cylinder pressure data acquired for two direct-injection diesel engines. The approach was focused on fitting a series of experimentally generated heat release and mean cylinder pressure profiles with a zero-dimensional, physics-based combustion model. A correlation for laminar flame speed was generated based on the optimal fit of flame speed to this series of ...
