Cooling

Increased cooling demands are integral with unparalleled power density and high power to volume ratios. Providing the required cooling for such a compact engine design is an extreme challenge that requires an innovative approach to both the cooling system and the various materials in the engine.

Development of Cooling Systems

Commercially available FEA software will be utilized to model the cooling and lubrication systems for the engine. The lubrication system is included in this effort since the lubrication system plays an important role in cooling the engine. Numerical analysis will be coupled with experimental results to optimize the cooling system to provide the necessary cooling within the power density and installed volume goals for the engine development program.
