Novel Methods for the Characterisation of Helicopter Aero-acoustics PhD
This PhD studentship is within the Propulsion Engineering Centre at Cranfield University, in the field of helicopter aerodynamic and aero-acoustic modelling. The work will develop and deliver rapid analysis capability, which can assist with the prediction of noise characteristics throughout the vehicle design and service-life. This will be accomplished through the development of a novel tool for the rapid source noise prediction of integrated helicopter-engine systems.
