Ice build up on aircraft wing surfaces destroys the smooth flow of air needed for stable flight. The latest deicing technology uses electrically heated mats layered into composite wing edge components. To safeguard aircraft performance and safety every component needs to operate within strict tolerances and be tested and validated as fit for purpose.
A purpose designed test rig provides high voltage insulation testing, heater and temperature sensor resistance tests. A programmed series of heater actuations at elevated supply voltage alternate with cold water being sprayed onto the part.
Testing of aircraft jet engines after maintenance and prior to refitting is vital for reliable and safe operation. Each engine test requires a log report providing details of the engine, all relevant test parameters and the engineers who supervised the test.
For each test the engine is run through a test sequence. Dependent
upon the resulting data it may be necessary to rerun steps in the
sequence in any order.
