Helicopter engine vibration analyzer 3656-A

portablewith data loggeraccelerometer

Vibration toolkit for field inspection of all helicopter engine families produced by Safran Helicopter Engines. Safran Helicopter Engine Vibration Test Kit Type 3656-A is designed for field inspection of all Safran helicopter engine families. Vibration test measurements are performed according to the respective maintenance manual. Type 3656-A has been developed by Brüel & Kjær in close collaboration with Safran, a leading helicopter engine manufacturer. The test kit comprises a vibration meter (with measurement templates for all Safran engines), a high-temperature accelerometer, and a 10 m cable, all packed in a handy shoulder bag. USE CASES Standard: Vibration check during a run-up from engine START to FLIGHT High N1/NGG rate: Vibration check during a run-up from FLIGHT to the maximum speed of the gas generator reachable on ground (or in flight for Arriel® 1 single-engine helicopters after Deep Maintenance Intervention) BENEFITS Immediate and unambiguous pass/fail decisions according to engine maintenance manual instructions Recording and documentation of test data according to Safran requirements for easy interaction with Safran Services FEATURES Verifies overall vibration levels in a specific frequency range during engine run-up/high N1-NGG rate against allowable limits SAFRAN HE templates for all engine families are included Message if level limitations are exceeded Metadata annotation according to SAFRAN HE requirements One-handed operation and simplified operator user interface Only one transducer and one cable needed No computer required during measurements No tachometer connection required
