Welcome to Test Cell 4, part of the Propulsion and Power Laboratory located in building M-7 in Ottawa, Canada.
Test Cell #4 is designed to test gas turbine aircraft engines in simulated icing conditions at sea level.
Established in 1941, it features a 12 foot diameter icing tunnel with 12 spray bars and 124 calibrated spray nozzles.
This facility is essential for certifying new engine designs before they are approved for flight.
Testing process involves mounting the engine in the test cell and connecting it to the icing tunnel.
Water and compressed air are then sprayed to form an icing cloud in the icing tunnel, which impacts the engine's performance.
The facility controls liquid water concentration and droplet size to replicate different cloud types, ensuring tests are conducted at temperatures ranging from -1ºC to -25°C.
The setup allows for thrust measurements while simulating icing conditions.
Thank you for touring Test Cell #4 at the NRC's Engine Research Facility.
We hope you've gained insight into the critical work that ensures aircraft engines can safely navigate icy skies.
