Aircraft noise remains the key inhibitor of the growth of air transportation, but the focus of the
noise mitigation strategies has changed. As the propulsor fan pressure ratio is decreased for …

New propulsive concepts, such as boundary layer ingestion, involve stronger interactions
between the engine and its environment, and are thus more complex flows compared to …

In the five-axis machining, the dual nonuniform rational B-spline (NURBS) interpolator
performs better than the conventional linear interpolator in improving machining efficiency …

The use of boundary-layer-ingesting, embedded propulsion systems can result in inlet flow
distortions where the interaction of the boundary-layer vorticity and the inlet lip causes …

To meet the increasing energy demand and to shave the peak, the Kingdom of Saudi Arabia
(KSA) is currently planning to invest more on renewable energy (RE) seeking diversity of …

Vehicles equipped with multiple electric machines allow variable distribution of propulsive
and regenerative braking torques between axles or even individual wheels of the car …

This project is focused on modeling the internal ow in centrifugal compressors for the
purpose of assessing the onset of rotating stall and surge. The current methods to determine …

Aeroengine fans and compressors increasingly operate subject to inlet distortion in the
transonic flow regime. In this paper, innovations to low‐order numerical modeling of fans …

When a turbofan engine flames out during flight, the ram pressure at the fan inlet creates an
internal flow that causes spool rotation. This regime is called windmilling operation [1], and …

The recent growth of private options in launch vehicles has substantially raised price
competition in the space launch market. This has increased the need to deliver reliable …
