Abstract
The US Navy faces daunting energy challenges that will further increase in severity, given the ever-increasing global demand for energy, diminishing energy supplies and demand for enhanced environmental stewardship. Navys environment foot print consists of both emissions and noise generated every day around the world. Additionally, noise is an important issue for the Navy due to the adverse effect it has on personnel and communities around naval air bases and training sites. Noise abatement technologies have received a boost in the commercial sector due to strict regulations and relatively smaller thrust demands placed on aircraft fleet. However military combat aircraft are designed to use high thrust engines with low bypass ratios and afterburners. All these factors lead to greater pressure mismatch at the exit of exhaust nozzles that accelerate noise generation. This scenario provides an exciting opportunity to streamline the nozzle design and attain the goals of improving efficiency and reducing noise simultaneously. For this purpose, IAI proposes to develop COMANDO, a tool for high-fidelity multi-physics based analysis and design optimization framework for advanced exhaust systems. COMANDO combines state of the art nozzle flow modeling techniques and multi-disciplinary optimization under a high performance computing environment to analyze design advanced nozzles.
