and

Hydraulic Components fitted on both Military Aircraft & Helicopter.

A/F27T-12 replaces A/F27T-10

The model JEHA MARK IV or HCT-12 (A/F27T-12) is newly designed to perform all functional and operational tests of new generation commercial aircraft hydraulic and pneumatic components including (and not limited to) actuators and control valves, from both large and mid-size body aircrafts. Optional P&MTC (Pump and Motor Test Console) provides capability of testing pump and motor and can be added to JEHA MARK IV or HCT-12 (A/F27T-12) at any time if required to expand the testing capability.

ADVANTAGE AND COMPARISON

NEW GENERATION JEHA MK IV OVER OLD GENERATION

ITEM	FEATURES	COMPETITION TEST BENCHES	JEHA MK IV
1	Advance Design	Old Technology based on 3,000 PSI Test Pressure.	New generation 6,000 PSI Hydraulic Test Bench with the latest state of the art features like Machine Human Interface (MHI) including built-in DAS on Main Hydraulic Console (MHC).
2	Human Machine Interface (HMI)	Not user friendly	The Human Machine Interface (HMI) is very user friendly, allows for human monitoring, input, and display of hydraulic fluid temperature & pressure, refrigeration temperature and pressure, ambient temperature, warning, and status indicators. All inputs from temperature and pressure sensors and HMI inputs are processed by a Programmable Logic Controller (PLC), which receives signal from temperature sensors, pressure transducers, and also from HMI inputs from MHC.
3	Programmable Logic Controller (PLC)	Competition is using custom hardware rather than standard commercially available controllers	The main tasks of the PLC are logic control, fault detection, system major faulty protective shutdown and data acquisition, including flow rates, pressures, temperatures, and condition of hydraulic oil filters. See attached JEHA MK IV PLC Channel List upon request.
4	Data Acquisition System (DAS)	DAS, PLC & HMI are likely located on a separate Console	DAS, PLC & HMI are located on the Main Hydraulic Console (MHC).
5	Graphic Displays	No or Limited Graphic Displays & MHC Channel Listing.	Graphic displays for parameters in form of digital data, can be displayed in HMI Screen, recorded and stored in HMI flash memory in the Excel compatible format. For parameters, see page 1/12, 2/12 and 5/12 as attached in HMI Display (MHC) upon request.
6	Test Sink Area (UUT)	Test Sink Area may be located on a separate Test Sink Area.	Test Sink Area fitted with Protective Cover is located on our MHC Console provides safety and ease of UUT Testing by Operator.
7	Inputs & Outputs	Limited Inputs & Outputs are also likely located on a separate Control Console.	All our Inputs & Outputs (1 to 126) are neatly located on our MHC Console, which offer ease of UUT Testing by Operator. See attached MHC Controls & Indicators upon request.
8	Specifications Testing & Environmental Qualifications	Built for commercial application without qualification to any stringent specification requirement testing.	JEHA MK IV has also been qualified to the most rigorous military requirement testing such as Environmental, Mobility, Electro Magnetic Interference, Reliability, Maintainability, Shock, Vibration, Sound Attenuation etc. as required by the US Government.
9	Production	In-production only as and when an Order is placed by Customer.	Currently with more than 80 Units in production for US Government & export market. Spares can be guaranteed for more than 20 years.
10	Gauges	Using traditional dial Gauges, which provide in-accurate readings caused by parallax reading or vibration.	No gauges, all readings are in digital numbers being displaced accurately on HMI Display Monitor.
11	Calibration	Instruments like Gauges, Temperature or Pressure Sensors, Flow Transducers etc. are required to be removed for third party annual calibration. Test Bench is out of action, time consuming and incurring annual calibration cost.	HII’s new generation design provides for calibration of these instruments at location, without requiring for their removal for annual calibration.
12	Components	Most Components are sourced from outside Vendors.	More than 90% including critical components like Temperature or Pressure Sensors, Flow Transducers, Air Driven Gas Boosters or Liquid Pumps used on JEHA MK IV are built in-house by our Pumps Division & Flowmetrics Inc. ensuring spares supportability for more than 20 years. .
13	Instrument Verification Set (IVS)	No	Instrument Verification Set (IVS) is available to verify the acceptable accuracy of built-in Instrument like Temperature or Pressure Sensors, Flow Transducers etc. without having to remove them for annual calibration.
14	Torque Calibration	No	Torque Calibration Arm is available for calibration and associated readout of the torque transducer while it was installed on a Pump Motor Test Stand.
15	Ease of Maintenance	Troublesome and time consuming to replace Filter Elements or any consumable parts.	For example, Filter Elements or any consumable parts are easily accessible and does not require disconnecting fittings and/or interconnecting hydraulic lines.
16	Fault Diagnostic	No	If a fault exists before system operation or a fault occurs during system operation, fault conditions will immediately report to HMI message field and an audible warning horn HRN is activated. All fault conditions are permanently stored to retentive memory of HMI computer, up to 200 fault conditions.
17	Life Cycle Cost	High Life Cycle Cost	Very Low Life Cycle Cost
18	Reliability Demonstration Test	No	The reliability test has been performed on the full range & capabilities of the MHC Pilot Production Unit (PPU) in accordance with MIL-HDBK-781A over 1000 hours without failures.

HCT-12 or JEHA MK IV is an universal Commercial Aircraft Components Test Bench which compromises of Main Hydraulic Console (MHC) and Pump and Motor Test Console (P&MTC). The MHC provides the Unit under Test (UUT) with the necessary input test parameters to perform functional and operational tests on hydraulic components/modules from new and old generation of both rotary and fixed wing aircraft through use of electrical, hydraulic and pneumatic circuits.

Since MHC is equipped with two independent high pressure dynamic circuits (each 20 GPM @ 6,000 PSI or 25 GPM @ 3,000 PSI), one independent low pressure dynamic circuit (max 10 GPM @ 250 PSI), one independent hydrostatic circuit (up to 10,000 psi) and two power supplies, one adjustable AC and one adjustable DC power supply, which they can be operated simultaneously, MHC can technically handle all required flow and pressure for testing various components as well servo controls and actuators.

P&MTC provides capabilities of testing hydraulic pump, motor and power transfer unit, and can be added to MHC at any time. MHC is the source of supplying hydraulic flow and pressure for testing of hydraulic rotating components, when connected to the Pump and Motor Test Console.
