Testing Components in a Climate Chamber: e.g. Aerospace Components The PPM 432 pulse test stand offers a powerful system for testing cooling components, hydraulic components, fluid systems and various other pressure vessels for the aerospace industry. For e.g. electronic units such as ECUs on board produce heat which has to be dissipated to ensure that the systems function reliably during flight. The pressure pulsation test stand simulates a controlled pressure change at various pressure ranges and temperature conditions. The system consists of two modules. The supply unit houses the pressure intensifiers, cooling and heating units and the control system. The actual testing takes place in a climate chamber in which the DUTs are tested at a media temperature of -40°F(-40°C) to +320°F (+160°C) and changing environmental conditions from -58°F (-50°C) to +320°F (+160°C). The pressure intensifiers can be designed to the customers’ requirements and components’ idiosyncrasies. A Common setup is a pressure intensifier for up to 1000 psi (70 bar), two for up to 4000 psi (275 bar) and one for up to 6000 psi (414 bar), while Aerospace oil is used as the test medium.
