Suppression of Thermal Emission from Exhaust Components Using an Integrated Approach
Abstract
This paper provides the results of an Phase I SBIR to develop an exhaust suppression virtual design model and exhaust suppression optimization using modeling techniques and hot flow testing. The virtual design model provides an estimate of space required for the exhaust backpressure to the engine, system. weight gas temperature distributions and the interaction of the plume with external surfaces both on the vehicle and the ground, and the thermal interaction of the exhaust system with external surfaces through internal convection, conduction. and radiation. A hot flow exhaust test rig has been designed that simulates both exhaust flow and engine bay cooling air flow. This is accomplished with two separate gas producers mounted on flat beds so that the rig is mobile and the sources can be positioned independent of each other.
