... Abstract Predicting details of aircraft engine combustion by means of numerical simulations requires reliable information about spray characteristics from liquid fuel injection. However, details of liquid fuel injection are not well documented. Indeed, standard droplet distributions are usually...

... Abstract Machine learning and big data have become the most disruptive technologies for organizations to improve workplace efficiency and productivity. This work explored the application of machine learning-based predictive analytics that would enable aircraft engine designers to estimate...

... Abstract Controls for transient operation of aircraft engine are highly important due to the fact that the transient performance depends on how the engine responds to throttle command via the control system. The Ndot control is widely used in modern aircraft engine that can produce a consistent...
