SOLUTION

FLOW SYSTEMS has designed and engineered a fully automated "standard" Liquid Fuel Nozzle Test System, including hardware and software, that is fully customizable for each application or customer. As a "standard" product offered by FLOW SYSTEMS, the test stand is continually undergoing improvements in both the hardware components and the controlling software. This continuous improvement process has produced a system that is used and accepted worldwide by many OEMs and suppliers in the Aerospace Industry. The system currently complies with the in-house testing procedures of ABB/Alstom Power, ABB Gas Turbines, Pratt & Whitney America, Pratt & Whitney Canada, General Electric Aircraft Engines, General Electric Power Systems, Mitsubishi Heavy Industries, Mitsubishi Power Systems, Solar Turbines, Allison Engine, Rolls-Royce, Siemens, Siemens-Westinghouse, Snema and others.

SYSTEM SCHEMATICS 

The Test Stand is a Liquid Flow Metering System that utilizes a coriolis flow meter to measure the liquid flow through each Unit Under Test (UUT). 

SYSTEM CONTROLLER SOFTWARE 


The System Controller handles the operation of the prime mover, sets the proper pressure at the Unit Under Test (UUT) and calculates the flow number through the UUT. The controller also monitors the liquid flow conditions to insure that the flow is stable within +/-0.1% of the pressure ratio set point. Shown below is a picture of the system Standard Production Screen.

Control System Operator Interface 

The System Controller Software contains procedures for performing the following functions:

Part Master Routine 

» Measures the repeatability, average and percent difference (measured to calculated) of a series of consecutive flow tests through a master Unit Under Test (UUT).

System Accuracy Test (Audit Test)

» Measures the repeatability, average and percent difference of a calibrated meter/nozzle against the installed system meter.

Test Scheduler

» Automated Test Sequencer.
» Allows any number of configured tests to be executed in a sequence.
» Virtual tests can be programmed in the schedule to calculate and evaluate results based on previous test values in algebraic equations.
» Enables stop/retest of tests in the schedule.
» Programmable Pause.

Maintenance

» Allows the user to manipulate all system controls and read all system sensors.
