Tech Talk - Acoustic and performance measurements obtained in the NASA Langley Small Hover Anechoic Chamber - Ms. Nicole Pettingill, Research Aerospace Engineer, Aeroacoustics Branch, NASA Langley, Thursday 4/29 @ 3PM EDT, Microsoft Teams bit.ly/VFSPettingill

What a great session today with the people from NASA Langley Research Center at #SIAMAN18 !! High performance computing, aeroacoustics, CFD, uncertainty quantification and more :)

🔊 Open Rotor Engine Simulation | #Aeroacoustics & #Aerodynamics 🔊

👉 Open rotor engines are expected to consume substantially less fuel when compared with traditional ducted turbofans. 🧵👇

I love my job! Spent this week doing #acoustic measurements in the Poul la Cour wind tunnel DTU Wind and Energy Systems. What a magnificent construction! #plct #aeroacoustics #windtunnel

Congratulations to Patrick Mills for successfully defending his MASc thesis on 'Flux Reconstruction as a Direct Method for Near-Field Computational Aeroacoustics' including the distinction of it being accepted with no modifications.

Congratulations Patrick!

A preprint of our Annual Reviews paper on high-speed gas-particle flows is online: doi.org/10.48550/arXiv… Justin Wagner Sandia National Labs and I provide historical perspectives + new insights from simulations & experiments on shock-particle interactions, multiphase aeroacoustics & more

Some drones swarm configurations save energy but also have smaller noise footprint. See latest research paper by Talib DBOUK(PhD, HDR) and dimitris drikakis University Nicosia entitled: Quadcopter Drones Swarm Aeroacoustics. Research published by AIP Publishing

Follow along with this #aeroacoustics tutorial to learn how to model an acoustic liner with a grazing background flow: buff.ly/2IRjPXs

The aeroacoustics on this is pretty wild. The dominant pitch corresponds to a frequency very close to 440 Hz. It's wild that the frequency is so close to the standard pitch reference for the A above middle C. In the 2-minute video the frequency only deviates about +/- 2 Hz.

End of day one and well done to more of our young scientists..

I did a hard thing. 🤪 After spending days w/ students preparing for, traveling to, & setting up Transporter 8 Falcon 9 launch noise measurements, I rented a car & drove 270 miles to the AIAA aeroacoustics conference last night. My head's in San Diego but my heart's in Lompoc.

Optimised noise insulation, aeroacoustics and vibration comfort: in order to ensure the best possible comfort ever realised in a BMW, THE NEW i7 is undergoing a diverse range of tests in our laboratories and test benches. #BMWGroup #THE7 #THEi7

An engine expected to consume far less fuel when compared with traditional ducted turbofans? Let us introduce you to open rotor engines. 🛫 This simulation demonstrates the capability of our PowerFLOW solver to predict the aerodynamics and the aeroacoustics of an open rotor.
