HEALTH MONITORING SYSTEMS OF HEPTRS

HEALTH MONITORING SYSTEMS OF HEPTRS

DETERIORATION IN PERFORMANCE OF SOME SYSTEMS WHICH CANNOT BE IDENTIFIED IMMEDIATELY AND EXHIBITS THE DECAY IN A PROLONGED DURATION WITHOUT ANY OBSERVABLE SYMPTOMSTOPICS NEED FOR PERFORMANCE MONITORINGPARAMETERS FOR MONITORING SYSTEMS OF MONITORINGANALYSIS OF VIBRATIONAL DATA FOR CONDITION MONITORINGRECORDING AND ANALYSING THE DATA OFF LINEADVANTAGES OF HEALTH MONITORINGHEALTH MONITORING IN CHEETAH/ CHETAK HEPTRS

NEED FOR PERFORMANCE MONITORINGFLT SAFETY

REDUCTION IN DOWN TIME OF AIRCRAFT

REDUCTION IN FAILURE RATE

EASY SNAG ANALYSIS

PARAMETERS FOR MONITORINGPHYSICAL PROPERTIES : TEMP, PRESSURE, VISCOSITY, VOLTAGE, CURRENT,TIME, EXPANSION ETC

VIBRATIONS- AT ALL POSSIBLE RPMS

VISUAL INSPECTION- DISCOLOURATION- CONTAMINATION- CRACKS / LOOSE FITTINGS- TELL-TALE INDICATIONSSYSTEMS OF MONITORINGON LINE HEALTH MONITORING ( DISPLAY & FDR)- VOLTAGE- CURRENT- SPEED- TIME - PRESSURE- TEMP- RPM- RATE OF CHANGE OF VARIOUS PARAMETERS- ACCELERATION ( GRAVITY EFFECT)- CHANGE IN HUMAN EFFORT( Pilots Feel)

ADDITIONAL PARAMETERS - VIBRATION ANALYSISANALYSING THE ENTIRE FREQUENCY SPECTRUM- ACOUSTIC SIGNALS USING FFT TO RESOLVE THE FREQ AND IDENTIFY THE SOURCE AND BALANCING- SPECTRAL OIL ANALYSIS PROCEDURE ( SOAPS)GATHERING USEFUL INFO FROM DEBRIS SUSPENDED IN OIL AND THE CHANGE IN ITS PHYSICAL PARAMETERS LIKE VISCOSITY, DISCOLOURATION, ETC- CRACK DETECTIONDYE PENETRANT, NDT

ANALYSIS OF VIBRATION DATA FOR CONDITION MONITORING-SIGNATURE SPECIMEN:COMPARING OLD AND THE NEW COMPT ON TEST BENCH

-FREQUENCY ENVELOPE MONITORING: FOR INITIATING PREVENTIVE MAINT

-CONDITION CHECKING FOR STD EQPT: EFFECTIVITY OF COMPT AT VARIOUS CONDITIONS ( LIKE VARYING AMP)

-VIBRATION TREND MONITORING: ASSESSING COMPT WEAROUT USING STATISTICAL DISTRIBUTION PATTERN RECORDING THE DATA ON/OFF LINEA DIGITAL FLT DATA RECORDER WITH VARIOUS SENSORS CAN STORE THE DATA ONBOARD LIKE MEMS ( MICRO ELECTRO MECHANICAL SYSTEMS) WHICH ARE - LT WT- UPTO 30 KG

- SAME TRANSDUCERS TO COVER MULTIPLE PARAMETERS

- BUILT IN CALIBRATION FACILITY

- WIRELESS SENSORS

ADVANTAGES OF HEALTH MONITORING SYSTEMS- AVOID HUMAN ERROR IN MAINTENANCE ASPECTS

- DATA RECORDING IS AVAILABLE- ANALYSIS OF DATA IS AVAILABLE

- SAVING IN SPARES

- EARLY FAULT DIAGNOSISHEALTH MONITORING IN CHEETAH/ CHETAKONLINE- VOLTAGE: BTY CONDITION- PRESSURE: ENG OIL, TXN OIL, FUEL SYSTEM- RPM: ENGINE, MAIN ROTOR, CLUTCH ENGAGEMENT- WARNING LT: ALL TYPES-TELL-TALE INDICATORS: AIRFRAME, FUEL FILTER CLOGGING-TIME: ICE, FCE,RDT, STARTING SEQUENCE, CHANGING PARAMETERS ETC-TEMP: JPT, TXN & ENG OILOFFLINE-OIL CONSUMPTION: MGB & ENG OIL-OIL CONDITION: VISCOSITY, CONTAMINATION & COLOUR CHECKS IN HYD, ENG AND TXN OIL.-UNUSUAL SOUND: ENGINE-VIBRATION CHECKS: ENG, MAIN ROTOR & TAIL ROTOR-AGEING COEFFICIENT: ENGINE CONDITION-COMPT LIFE: ROTABLES-VISUAL CHECKS: -CRACKS ALL KINDS -DISCOLOURATION OF ANY COMPT-WEARING OF ANY COMPT-LEAKAGE OF ANY KIND-ANY LOSE FITTINGS
