Application of real-time engine simulations to the development of propulsion system controls [PDF]

The development of digital controls for turbojet and turbofan engines is presented by the use of real-time computer simulations of the engines. The engine simulation provides a test-bed for evaluating new control laws and for checking and debugging ...

Finite element-integral simulation of static and flight fan noise radiation from the JT15D turbofan engine [PDF]

An iterative finite element integral technique is used to predict the sound field radiated from the JT15D turbofan inlet. The sound field is divided into two regions: the sound field within and near the inlet which is computed using the finite element ...

Utilizing numerical techniques in turbofan inlet acoustic suppressor design [PDF]

Numerical theories in conjunction with previously published analytical results are used to augment current analytical theories in the acoustic design of a turbofan inlet nacelle. In particular, a finite element-integral theory is used to study the effect
