EXECUTIVE SUMMARY

This Navy Training System Plan identifies the life cycle manpower, personnel, and training required to support the A/E 37T-32 Vibration Analysis Test Set (VATS) program. The VATS is a multi-function instrumentation system used for vibration analysis, propeller balancing, and helicopter rotor tracking and balancing. The VATS is also used for fault isolation in aircraft drive systems, flight controls, and airframe components, supporting both rotary and fixed wing aircraft. The Initial Operational Capability for VATS was attained in September 1990. VATS is in Phase III (Production, Deployment, and Operational Support) of the Weapon System Acquisition Process.

Navy personnel operate the VATS at the organizational and depot maintenance levels, and it is maintained by intermediate and depot level maintenance personnel. Personnel from intermediate level Work Center 670 Precision Measuring Equipment and Field Calibration Activity repair VATS. The VATS camera and three of the internal cards in the Computer Indicator Power Supply (CIPS), which include the Random Access Memory (RAM) card, the extended memory RAM card, and the analog input number two card, are repaired at the depot level. VATS introduction has not caused an increase or decrease in previously existing manpower requirements.

Technical Evaluation (TECHEVAL) was completed at the Naval Air Warfare Center Aircraft Division (NAWCAD), Patuxent River, Maryland. The VATS manufacturer, Dynamic Instruments, Inc., conducted initial training in second quarter FY91. Naval Air Technical Data and Engineering Service Command (NATEC) representatives and Navy instructors from various activities attended initial training.

Follow-on training is integrated into existing power plants training tracks for each type aircraft. Vibration Analysis Theory and Familiarization training is conducted at the Maintenance Training Units (MTU), Naval Air Maintenance Training Units (NAMTRAU) located at Naval Station (NS) Norfolk, Virginia; Naval Air Station (NAS) North Island, California; NAS Jacksonville, Florida, and Naval Air Maintenance Training Group Detachments (NAMTRAGRU DET) Marine Corps Air Station (MCAS) Miramar, California; Marine Corps Base (MCB) Camp Pendleton; and NS Mayport, Florida. All courses have been modified and require no further changes. Modifications performed did not cause any changes in course or track lengths. NATEC representatives conduct Practical Job Training as required.

MTU 1025 NAMTRAGRU DET will be moving from MCAS Miramar to NAS Point Mugu, California, beginning in June 2000. The move is currently scheduled for completion with all courses ready for training in October 2000.

D. SYSTEM DESCRIPTION

1. Operational Uses. The A/E 37T-32 VATS is used on Navy and Marine Corps aircraft by organizational and depot maintenance personnel to track and balance rotors, propellers, and turbofans, and to monitor the vibration of aircraft and aircraft dynamic components under field conditions. The VATS is capable of measuring the vibration frequency and magnitude for engines, transmissions, gear boxes, dynamic drive systems, and airframes. The VATS is used to fault isolate vibration discrepancies and monitor the health of dynamic components and the airframe through vibration trend analysis tracking.

Vibration Analysis (VA) is a means of determining mechanical system faults such as imbalance, misalignment, mechanical looseness, gear tooth defects, bearing defects, and structural and component resonance. The VATS is used as a VA failure isolation and prediction tool. This results in increased readiness due to a reduced vibration discrepancy maintenance workload.

VA tasks which the VATS is intended to accomplish are:

    • H-53 main and tail rotor track and balance, transmission, gearbox, drive shafts, and airframe monitoring
    • H-3 main and tail rotor track and balance, transmission, gearbox, drive system, and airframe monitoring
    • H-60 main and tail rotor track and balance, transmission, gearbox, drive system, airframe monitoring, and vibration absorber tuning
    • H-1 main and tail rotor track and balance, transmission, gearbox, drive system, airframe monitoring, and vibration absorber tuning
    • E-2 and C-2 on-aircraft propeller balancing and airframe monitoring
    • S-3 fan rotor assembly balancing

Other aircraft utilize several different types of equipment for VA and are not mentioned in this NTSP for that reason.

2. Foreign Military Sales. Not Applicable (NA)

E. DEVELOPMENTAL TEST AND OPERATIONAL TEST. VATS Technical Evaluation and Operational Evaluation were conducted in August 1990 by the Propulsion Support Equipment Evaluation and Verification Branch, Naval Air Warfare Center Aircraft Division (NAWCAD), Patuxent River, Maryland. Software testing is ongoing at NAWCAD Patuxent River, Maryland, and NAWCAD Lakehurst, New Jersey.

F. AIRCRAFT AND/OR EQUIPMENT/SYSTEM/SUBSYSTEM REPLACED. VA systems formerly in use were designed to meet individual needs for specific aircraft and engines. The two VATS configurations, fixed and rotary wing, replaced all of the VA equipment listed in the table below:

G. DESCRIPTION OF NEW DEVELOPMENT

1. Functional Description. The VATS is used on Navy aircraft by organizational and depot level maintenance and flight crew personnel. It is capable of being placed in the aircraft for in-flight troubleshooting and VA without degrading aircraft operation. The VATS is comprised of the following six subsystems, in three portable instrument cases.

a. Fast Fourier Transformer Analyzer. The Fast Fourier Transformer Analyzer is used to record real-time frequency analysis of the input signal.

b. Magnetic Media Input-Output Module. The Magnetic Media Input-Output Module is used to record digital information data appearing on the visual display or machine.

c. Sensors. The Sensors consist of the optical tachometer and the accelerometers. A line-scan camera provides data to the optical tachometer and the analyzer.

d. Flat Panel Display. The Flat Panel Display is an operator visual display unit with alphanumeric and graphic capabilities.

e. Machine Transcribed Record (Hard Copy). This is a device capable of producing hard copy records of both the alphanumeric and graphic data that appear on the Flat Panel Display.

f. Integrated Operator Interface. The Integrated Operator Interface enables the operator to select tests or functions, enter data, and communicate with the test unit.

2. Physical Description. The dimensions of the three portable instrument cases containing VATS are 15.5" x 18.5" x 11.5", weighing between 35 and 43 pounds.

    • Instrument case one contains the Computer Indicator Power Supply which includes the control panel, display, keyboard, and connector panel.
    • Instrument case two contains the remote control and optical sensing units (rotary wing configuration only), five triaxial accelerometers, three single axis accelerometers, two rotor blade tachometer pickups, various brackets and blocks used for mounting the sensors to the airframe, and accessory cables.
    • Instrument case three contains the printer disk drive and accessory cables.

3. New Development Introduction. The VATS was introduced as new production equipment, and is not currently in production.

4. Significant Interfaces. NA

5. New Features, Configurations, or Material. Existing units are currently being upgraded by Engineering Change Proposal 4871-2-98, which changes the display monitor from black and white to a color presentation, making it easier to read in sunlight. Other changes since the last version of this NTSP have been modifications to the supporting software and upgrading the processor to Pentium class. Support Equipment Change 5470, which addresses all upgrades to VATS, is expected to begin incorporation in July 2000.

H. CONCEPTS

1. Operational Concept. VATS operation is conducted in-flight and during ground maintenance. In-flight operation of VATS equipment is performed by qualified flight crew personnel and ground operation by qualified Navy Aviation Machinist's Mate (AD) maintenance personnel and Marine Corps personnel in Work Center 110. Only qualified maintenance personnel analyze the data collected by the VATS.

2. Maintenance Concept. VATS are pre-positioned at the supporting Aircraft Intermediate Maintenance Departments (AIMDs) as part of the Individual Material Readiness List (IMRL), and are sub-custodied to the supported squadrons. The VATS is used by organizational and depot maintenance personnel and is repaired by intermediate and depot maintenance personnel.

a. Organizational. Maintenance consists of pre-operational and post-operational inspections, and installation, operation, and removal of the equipment on the aircraft.

b. Intermediate. Navy Aviation Electronics Technician (AT) maintenance personnel in AIMD Work Center 670 and Marine Corps personnel assigned to calibration activities conduct fault isolation of the VATS to defective Shop Replaceable Assemblies (SRAs), and repair, recalibrate, or replace the subassemblies using the VATS maintenance manual NAVAIR 17-15BBA-8. Navy Aviation Electrician's Mate (AE) and AD maintenance personnel and Marine Corps personnel perform operational testing of the VATS in AIMD Work Center 450.

c. Depot. Naval Aviation Depot (NADEP) Cherry Point, North Carolina, maintenance personnel accomplish the VATS camera (optical sensing unit) and the Computer Indicator Power Supply (CIPS) calibration. Dynamic Instruments, Inc. repairs three of the VATS internal cards, the Random Access Memory (RAM) card, the extended memory RAM card, and the analog input No. 2 card. Special equipment has been procured to enable verification of the VATS accelerometer tolerance and range as required by the calibration program, expanding the current capability of the NADEP Cherry Point calibration program. Calibration procedures can be found in NAVAIR 17-20AW-296.

d. Interim Maintenance. Interim intermediate and depot level maintenance performed by Dynamic Instruments, Inc. ended in August 1995.

e. Life Cycle Maintenance Plan. NA

3. Manning Concept. VATS equipment is designed to replace existing vibration test sets, and does not require additional manpower at the organizational or intermediate levels of maintenance. No changes are required to current billet structures or to the available skill levels. No specific Navy Enlisted Classifications (NECs) or Military Occupational Specialties (MOSs) are required for the organizational level AD or the intermediate level AD, AE, and AT ratings or Marine Corps personnel for VATS operation and maintenance.

4. Training Concept. Formal intermediate level training for Work Center 670 technicians is not required to support the VATS. Naval Air Technical Data and Engineering Service Command (NATEC) representatives conduct Practical Job Training (PJT) as required. Aircrew operator training is not required for in-flight VA testing.

a. Initial Training. Initial training was completed in 1991.

b. Follow-on Training. VATS organizational level operator and maintenance training required a minor modification to existing power plants training tracks. No change to track length was required. NATEC representatives conduct PJT at the individual organizational units. Follow-on training for each aircraft is conducted at the Maintenance Training Units (MTU) Naval Air Maintenance Training Units (NAMTRAU) and Naval Air Maintenance Training Group Detachments (NAMTRAGRU DET) listed below.

I. ONBOARD (IN-SERVICE) TRAINING

1. Proficiency or Other Training Organic to the New Development. VATS organizational level operator and maintenance training required a minor modification to existing Power Plants training tracks. No change to track length was required. NATEC representatives conduct On-the-Job Training at the individual organizational units.

a. Aviation Maintenance Training Continuum System. AMTCS will provide career path training to the Sailor or Marine from their initial service entry to the end of their military career. AMTCS is planned to be an integrated system that will satisfy the training and administrative requirements of both the individual and the organization. The benefits will be manifested in the increased effectiveness of the technicians and the increased efficiencies of the management of the training business process. By capitalizing on technological advances and integrating systems and processes where appropriate, the right amount of training can be provided at the right time, thus meeting the Chief of Naval Operations (CNO) mandated "just-in-time" training approach.

Technology investments enable the development of several state-of-the-art training and administrative tools: Computer-Based Training (CBT) for the technicians in the Fleet in the form of ICW with Computer Managed Instruction (CMI) and Computer Aided Instruction (CAI) for the schoolhouse.

Included in the AMTCS development effort is the Aviation Maintenance Training Continuum System - Software Module (ASM) which provides testing [Test and Evaluation (TEV)], recording [Electronic Training Jacket (ETJ)], and a Feedback system. The core functionality of these AMTCS tools are based and designed around the actual maintenance-related tasks the technicians perform, and the tasks are stored and maintained in a Master Task List (MTL) data bank. These tools are procured and fielded with appropriate COTS hardware and software, i.e. Fleet Training Devices (FTD) - Laptops, PCs, Electronic Classrooms (ECR), Learning Resource Centers (LRC), operating software, and network software and hardware.

Upon receipt of direction from OPNAV (N889H), AMTCS is to be implemented and the new tools integrated into the daily training environment of all participating aviation activities and supporting elements. AMTCS will serve as the standard training system for aviation maintenance training within the Navy and Marine Corps, and is planned to supersede the existing MTIP and Maintenance Training Management and Evaluation Program (MATMEP) programs.
