Cycle Performance Analysis
Analyze steady-state thermodynamic cycles, component maps, thrust, fuel consumption, pressure ratios, emissions, and off-design operating points for aircraft, industrial, and power-generation gas turbines.
SimTurbo gives engineers, researchers, and educators an intuitive environment for numerical propulsion system simulation. Build component-based gas turbine models, evaluate steady-state and transient behavior, test control logic, and visualize results in real time. From conceptual architecture studies to validated turbojet analysis, the platform helps teams turn complex aero-thermodynamic questions into practical, data-informed engineering decisions.
Model, analyze, validate, and optimize gas turbine systems across performance, architecture, controls, and dynamic operating conditions.
Analyze steady-state thermodynamic cycles, component maps, thrust, fuel consumption, pressure ratios, emissions, and off-design operating points for aircraft, industrial, and power-generation gas turbines.
Configure complete gas turbine architectures with graphical, component-based tools for conceptual design, component matching, shaft arrangements, combustor configuration, and performance optimization.
Simulate startup, shutdown, throttle changes, acceleration, load shifts, actuator dynamics, sensor response, faults, and environmental variations to evaluate dynamic engine behavior.
Develop and validate PID control, fuel scheduling, FADEC logic, protection systems, gain scheduling, and closed-loop transient response for propulsion and power systems.
Model single-spool turbojet compressors, combustors, turbines, nozzles, thrust, fuel use, operating envelopes, controls, and transient performance for education, research, and aerospace analysis.
Develop dual-spool turbojet models that capture high- and low-pressure spool interaction, compressor matching, turbine performance, controls, off-design behavior, and system-level optimization.
SimTurbo supports numerical propulsion system simulation without hiding critical component relationships inside a black box. Its graphical, component-based environment helps users architect gas turbine systems, assess cycle performance, investigate transient events, and validate control laws on standard PCs. Interactive diagrams and real-time plots make model behavior easier to inspect, while export options support deeper post-processing in Excel, MATLAB/Simulink, or Python.

Numerical Propulsion System Simulation (NPSS) generally refers to a modeling approach and software environment used to represent propulsion-system components and their interactions. Engineers use these simulations to evaluate thermodynamic cycles, component matching, thrust, fuel consumption, off-design performance, and controls. SimTurbo provides a graphical, component-based environment for gas turbine performance, transient behavior, and control-system analysis.
