Product Code:SAE ARP704
Title:Helicopter Engine - Rotor System Compatibility
Issuing Committee:S-12 Helicopter Powerplant Committee
Scope: This SAE Aerospace Recommended Practice (ARP) recommends a methodology to be used for the design, analysis and test evaluation of modern helicopter gas turbine propulsion system stability and transient response characteristics. This methodology utilizes the computational power of modern digital computers to more thoroughly analyze, simulate and bench-test the helicopter engine/rotor system speed control loop over the flight envelope. This up-front work results in significantly less effort expanded during flight test and delivers a more effective system into service.The methodology presented herein is recommended for modern digital electronic propulsion control systems and also for traditional analog and hydromechanical systems.
