Engine Control Input Simulation for N1/N2 Speed and Vibration

The patent creates a virtual copy of the gas turbine engine system through a digital twin model that replicates engine behavior, speed signals, and vibration characteristics. This virtual model allows EEC system testing to be performed on copied data rather than requiring actual engine operation, thereby maintaining test authenticity while eliminating resource consumption associated with physical engine testing

The patent replaces the mechanical physical engine system with a computational digital model. The digital twin uses software-based simulations to generate speed and vibration signals that substitute for physical sensor measurements, replacing the need for actual mechanical engine operation while preserving the functional characteristics needed for EEC testing

The patent prepares and validates the digital twin model in advance before actual EEC testing begins. The virtual model is pre-calibrated to accurately represent engine behavior across various operating conditions, allowing rapid iteration and testing of EEC algorithms without requiring repeated physical engine setups. This preliminary preparation enables fast, accurate testing while minimizing actual engine operation time

The digital twin model dynamically adapts to simulate various engine operating conditions, speeds, and vibration scenarios on demand. This dynamic simulation capability allows the system to quickly change test parameters and scenarios without the physical constraints of actual engine operation, enabling comprehensive performance optimization testing in a fraction of the time required for physical testing
