GLACIER Facility Capabilities


The test facility accommodates the largest aircraft engines in existence today, and will support the future growth of gas turbine engines of up to 667 kN (150,000 lbs.) force thrust and 142 kN (32,000 lbs.) reverse thrust with fan diameters of up to 140 inches.
A four post test stand, oriented in the direction of the prevailing winds, houses a high accuracy thrust measurement system and an integral engine docking system for quick engine installation and removal.
Testing is conducted from the warm comfort of a control complex, outfitted with a state-of-the-art MDS proDAS data acquisition system. The system has the capability to measure all key engine parameters, perform high speed data logging and post-processing analysis.


Integral to the center’s performance, the test stand is equipped with a state-of-the-art icing system, which has been designed and supplied by the National Research Council. The system consists of a direct connect icing tunnel and multiple spray bars to control both water concentration and droplet diameters. GLACIER has established a baseline for aircraft icing certification worldwide, and is the first and only facility capable of certifying new growth engines under current and future regulatory requirements.
