Environmental Control Systems Simulation

GT-SUITE’s comprehensive library of thermal and fluid templates empowers users to quickly create ECS models

Air Cycle Machine Modeling

Environmental Control SystemsWIDE RANGE OF CAPABILITIES

Design and run system simulations of complete aerospace environmental control systems (ECS) including air cycle machines (ACM) and refrigerant vapor-compression loops. Such models can be used to study the air supply ducting, pressurization, humidity control, and thermal management of cabins. The cooling of other subsystems can also be modeled, such as avionics, fuel systems, gearboxes, transmissions, and more.  Steady state or transient (i.e. mission/flight cycles) can be easily set up to study common loading scenarios such as take-off under arbitrary ambient conditions. Applications include the study of worst case scenarios or of common duty cycle operation to ensure comfort and safe system operation.

GT-SUITE’s comprehensive library of thermal and fluid templates empowers users to quickly create ECS models, while mixing and matching various modeling fidelity levels of system components (heat exchangers, valves, pipes, etc.). Built-in optimization and DOE tools allow component sizing, system layout, and optimization of control strategies. 3D tools packaged with GT-SUITE allow fast conversion of flow systems from CAD data to 1D piping networks or 3D Cabin models (i.e. to study comfort).

Beyond thermal and fluid, GT-SUITE supplies complete component libraries which simulate the physics of mechanical, electrical, magnetic, chemistry, and controls components as well. This allows the possibility to integrate an ECS system with any other type of physical system to study interactions.
