Potential Technology to Unclog Hot Day Operational Limit 2010-01-1788

Fuel has been a popular choice for thermal system designers to use for absorbing aircraft accessory heat load due to its consumable nature. However, the shortcoming of using fuel as a heat sink is the dependency of environmental conditions. This deficiency has plagued the current United States Air Force fleet operation especially performing ground hold and low altitude attack mission during hot days. A Northrop Grumman led industrial team, commissioned by AFRL Power directorate through the INVENT program, has vigorously explored potential technologies to assist air force to enhance the mission capability. The results show various promising technologies not only can extend the hot day operational limit but also can potentially have an unrestricted capability. This paper describes the results from the study performed by Northrop Grumman for an advanced unmanned air vehicle (AUAV) for potential technologies and discusses the modeling approach in support of the analytical process.
