ADVANCED METHODS OF HELICOPTER PROPULSION SYSTEM INTEGRATION/AIR MANAGEMENT SYSTEM DESIGN

Advanced methods for accurately calculating the performance of helicopter propulsion/air management systems have been developed. These methods permit the rapid investigation of a large matrix of separate, related ways of meeting total air flow and power management requirements of modern helicopters. Performance comparison maps are generated in very short times that make valid comparisons of the several systems parameters permitting extensive optimization of proposed systems to meet performance, weight and reliability goals. Included in these systems requirements are engine bay cooling, engine and transmission oil cooling, air intake and particle separator definition, environmental control system definition and exhaust plume/hot metal IR signature suppression.
