Abstract

Estimating the residual useful life (RUL) time of turbofan engines is a determinant factor for aviation safety. Different methods of machine learning are explored in the field of turbofan health estimation and prognosis, to save maintenance cost and enhance aviation safety. An algorithm used for turbofan engines residual user life estimation called gaussian mixture model and hidden Markov model is one of the most effective method many researchers used in complex system health estimation and prognosis. However, Gaussian Mixture Model and Hidden Markov Model (GMM-HMM) has N2 computational complexity, which is always time consuming under the condition of large dataset is available. During past two decades, along with more and more advanced sensors are used for turbofan engine health monitoring, since a large amount of data is available for observation and analyzation. Parallel computing library such as CUDA is extremely necessary. In this paper, CUDA library is adopted for turbofan engines RUL estimation. The performance of algorithms is demonstrated on a simulated aviation dataset generated by the Commercial Modular Aero-Propulsion System Simulation (CMAPSS).
