Engine Architecture Design
Build and refine complete gas turbine configurations with graphical component selection, shaft arrangements, combustor layouts, compressor and turbine matching, and conceptual performance studies.
Turn complex gas turbine concepts into clear, testable engineering insight with SimTurbo. Model engine architectures, evaluate steady-state and transient performance, refine controls, and explore advanced cycles in a graphical environment. Built for aerospace engineers, researchers, and academic teams, the platform supports real-time simulation, component-level visibility, and data export for deeper analysis in your preferred engineering workflow.

Specialized gas turbine simulation tools for propulsion design, analysis, optimization, control validation, and research.
Build and refine complete gas turbine configurations with graphical component selection, shaft arrangements, combustor layouts, compressor and turbine matching, and conceptual performance studies.
Evaluate Brayton-cycle performance, thrust, power, fuel consumption, pressure ratios, component maps, ambient conditions, and off-design operating points for informed engineering decisions.
Analyze dynamic engine behavior through startup, shutdown, throttle changes, acceleration, deceleration, environmental variation, actuator response, and fault-condition scenarios.
Design and validate PID controls, fuel schedules, FADEC logic, protection systems, gain scheduling, sensor models, and closed-loop transient responses.
Model single- and dual-spool turbojet systems, including spool interaction, compressor and turbine matching, nozzle performance, thrust prediction, and control-system integration.
Explore recuperated, regenerated, reheated, intercooled, and afterburning gas turbine configurations for fuel-efficiency, thermal-performance, emissions, and propulsion-concept studies.
SimTurbo gives engineering teams a component-based environment for turning propulsion concepts into analyzable models without treating the engine as a black box. Create architectures, inspect operating behavior, compare steady-state and transient results, and validate control approaches in real time on a standard PC. Export simulation data for post-processing in Excel, MATLAB/Simulink, or Python while maintaining visibility into the physics behind each system decision.

Aerospace modeling and simulation uses digital representations of propulsion systems and their components to predict how they will behave before physical testing. For gas turbines, this can include thermodynamic cycles, compressor and turbine matching, thrust, fuel consumption, controls, startup behavior, and off-design operation. It helps teams compare concepts, identify constraints, and make engineering decisions with less reliance on early hardware iteration.
