Test Cell Design for the Development of a Hydrogen Internal Combustion Engine: Risk Mitigation of Hydrogen Leakages in a 20-feet Container

A collaborative group comprising of the TU Delft, Deltion College and Dutch Electric Aviation Centre aim to develop a flying test bed for sustainable aviation. The collaborative group has acquired a Cessna 337F Skymaster with the intent to replace one of the engines with a retrofit hydrogen internal combustion engine. An ancillary engine will...

Test-cell & On-wing Turbofan Performance Comparison at KLM Engine Services

After maintenance, turbofan engines are subjected to a performance acceptance test in an indoor test-cell to demonstrate that corrected performance thresholds are met. The same indicators are also monitored after on-wing installation. Despite corrections for operation conditions, differences are observed between test-cell and subsequent on-wing...
