|
 | A method for the evaluation of military hybrid electric vehicle thermal management systems has been developed. The approach allows for the generation of a set of evaluation metrics for determination of the effectiveness of existing systems and the means to assess alternative concepts and advanced approaches. Further, through the use of a set of deterministic performance metrics the methodology allows for evaluation of performance margins for adverse boundary conditions and ... |

|
| A decomposition kinetic model was developed based on thermodynamic theory, first-order reaction law, and PDSC and modified TGA techniques. This kinetic model is able to predict grease degradation life at various temperatures using their activation energy. In addition, the kinetic model was found to have a good correlation with the ASTM D 3527 test method that was simulated using a front wheel bearing system. The advantage of this kinetic model ... |

| Crew injuries and fatalities of military personnel in vehicles are a significant concern in the U.S operations in Iraq and Afghanistan. And the predominant cause is Improvised Explosive Device (IED) attacks on vehicles. A computational model using MADYMO, a mathematical dynamics modeling software, which utilizes lumped parameter, rigid body and finite element methodologies, was developed for the study. MADYMO simulations were performed with the correlated MADYMO model to understand the ... |

|
| The overall goal of the HMMWV Improvements Monster Garage(copyrighted) Program was to find readily accessible ways to increase payload, performance and protection. Each of these areas had been compromised over the course of time due to unanticipated threats and increased weight on the High Mobility Multipurpose Wheeled Vehicle (HMMWV), which has led to a decrease in payload and performance. The basic request from the Vice Chief of Staff of the ... |

|
| The Office of the Secretary of the Defense (OSD), Advanced Systems and Concepts, established the OSD Assured Fuels Initiative, which aims to spark commercial production of clean fuels made from U.S. energy sources for use by the U.S. Military. The Department of Defense (DoD) will provide the spark by developing the fuel specifications needed, demonstrating and qualifying the use of these fuels in tactical ground vehicles, aircraft, and ships, and ... |
