The High Pressure Test Stand is a portable test system that is used to test Environmental Control System components such as Primary Bleed Air Regulating & shutoff Valve, Secondary Bleed Air Pressure Regulator & Shutoff Valve, Primary Heat Exchanger Bypass Modulating & Shutoff Valve etc.

The test stand is designed for carrying out test procedures on pneumatic ACM units. Console and piping system are used for aircraft Air Cycle Machine testing.Console instrumentation contains: oscilloscope, spectrum analyzer, DC volt & ammeters, humidity, rpm, vibration, temperature indicators, timer and flow computer.Air Service: 80-100 psig @2-4 scfmEach section has several air pressure and vacuum systems, plus 120 Volt, 60 Hz, 400 Hz, and DC electrical circuitsElectrical Service: 120 V, single phase, 60 Hz.

The test stand is designed for carrying out tests on pneumatic component with airflow up to 27 pounds per minute at 600 psig. The test stand is of welded steel monocoque construction. The instrumentation and controls are arranged, insofar as possible, so that they may be easily read and operated when the operator is standing on the floor at the front of the stand.

The test stand is designed for carrying out test procedures on various aircraft pneumatic valves. The stand is comprised of 3 major items:The Test ConsoleThe Valve FixtureThe Altitude ChamberLeading Particulars:Air service: 300 psig, 800 psig NitrogenVacuum Pump motor: 3HP, 1750 rpmPower required: 460 V, 3 phase, 60 Hz

The test stand is designed for carrying out test procedures on various pneumatic valves. The stand consists of 2 units (the test rig & the portable console) and also an external air circuit. The stainless steel rig has an aluminum structural framed enclosure with a polycarbonate safety shield that can be raised and lowered. Large airflows are measured by the orifice (left end of photo) while small airflows can be measured by four mass air flowmeters in the rig.

This test stand is designed for the purpose of testing new or overhauled Pneumatic Sensor Assemblies. Model 39296 features two Mensor CPC6000 Multi-Function Pressure Controllers and a fully automated data acquisition system. The test stand has the capability to carry out a fully automated test procedure on two Pneumatic Sensor Assemblies. Each pressure controller is equipped with two pressure sensors, 0-30 PSIA and 0-65 PSIA. These highly accurate pressure sensors (0.01% IS-50) are used to precisely control and accurately measure air or vacuum test points from full vacuum to 65 PSIA. Model 39296 incorporates a computer based data acquisition system using National Instruments hardware. Instrumentation signals including pressure and voltage are fed into the data acquisition hardware. A custom software program that is developed in LabVIEW controls the fully automated test procedure, reads, displays, and creates a test report of the necessary parameters to complete the test procedures.

The ACM test stand is used to control test parameters while performing operational testing on the EC70 air cycle machine. Three motor-operated butterfly valves and two manuals control air flow through the ACM and secondary heat exchanger. The heat exchanger is used to ensure exact aircraft conditions are met for the ACM under test. Various sensors or ports are available to read temperatures, pressures, shaft displacement etc. by remote data system.

The test stand is designed for carrying out test procedures on cabin pressure outflow valves. Vacuum is applied to the smaller pressure vessel during certain testing and when larger volume is required a valve is opened to increase test chamber volume. Vacuum is applied by parallel 50 HP vacuum pumps.
