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.

Product Code:SAE AMS3315
Title:Silicone (Vmq) Rubber Sheet, Glass Cloth Reinforced
Issuing Committee:Ams P Polymeric Materials Committee
Scope:This specification covers a silicone (VMQ) rubber reinforced with glass cloth. This product has been used typically for gaskets or seals requiring a thin, resilient, nonporous sheet material suitable for operating from -55 to +205 degrees C (-67 to +401 degrees F), but usage is not limited to such applications. This material is resistant to deterioration by weathering and petroleum-base engine oil and remains flexible over the temperature range noted. This material is not normally suitable for use in contact with gasoline or aromatic fuels and low-aniline-point petroleum-base fluids due to excessive swelling of the elastomer.【英文标准名称】:Standardfor4.76kVto38kVRatedGroundingandTestingDevicesUsedinEnclosures
