Share On:

In this series, we highlight our continued effort to study the fluid dynamics of the XV-15 tiltrotor aircraft. The full series consists of three parts: Part I provides some background on the need and utility of tiltrotor aircraft and summarizes the CFD study we carried out in 2021 using the Detached Eddy Simulation (DES) technique. Part II will discuss useful fluid dynamic propulsion approximations to model the XV-15 at a reduced computational cost. Part III will showcase the results obtained...

In a recent breakthrough published in Nature Photonics, a high-efficiency, high-bandwidth spatial light modulator (SLM) has been developed. The work, led by Chris Panuski and prof. Dirk Englund at the Massachusetts Institute of Technology, demonstrates a proof-of-principle device based on an array of photonic crystal microcavities with all-optical control of the resonance frequencies of each individual cavity. A key innovation was the cavity design, which was optimized simultaneously for high spatial confinement, high quality factor and high directionality of the...
