Specialized simulation, analysis, control-design, and engineering support for complex gas turbine systems.
Configure and optimize complete gas turbine architectures with component selection, shaft arrangements, combustor configurations, compressor and turbine matching, and performance studies.
Evaluate thermodynamic cycles, efficiency, thrust or power, fuel consumption, pressure ratios, ambient conditions, and off-design engine performance using detailed models.
Analyze dynamic engine behavior during starts, shutdowns, throttle changes, load changes, environmental variations, and fault conditions to improve response and stability.
Develop and validate PID controls, fuel scheduling, protection logic, sensors, actuators, gain scheduling, and FADEC-oriented control strategies in closed loop.
Explore recuperated, regenerated, reheated, intercooled, and afterburning configurations to assess energy recovery, thermal performance, efficiency, emissions, and advanced propulsion concepts.
Model single- and dual-spool turbojet systems for compressor and turbine matching, nozzle performance, thrust prediction, transient behavior, control integration, and validation.
SimTurbo gives engineering teams a graphical, component-based environment for designing and evaluating gas turbine systems without treating the model as a black box. Build configurations, adjust parameters, and examine steady-state or transient behavior with interactive diagrams and graphs. Across U.S. aerospace, marine, power, and university applications, users can export results for further work in Excel, MATLAB/Simulink, or Python.
