We have been building a Mach 0.5 recirculating wind tunnel for, believe it or not … 10 (!!) years … there were various challenges and setbacks, but lots of students contributed to this and the tunnel finally turned on today! See the turn on video at https://youtu.be/m5LAk-bmYgU
The sonic anemometer successfully flew from New Zealand to Argentina on a NASA/CSBF stratospheric balloon, and is back on the ground! System has been recovered successfully. Waiting for this to return to Tufts so we can pull all the data off!
The Tufts Sonic Anemometer launched from New Zealand on a NASA/CSBF heavy lift stratospheric balloon! It will travel across the Pacific gathering stratospheric wind data. You can see the flight data returned from our onboard system at https://ultrasonic-anemometer.onrender.com
The NASA/CSBF team has recovered the Antarctica balloon! We received the shipment back at Tufts June and are starting to look at the data. It looks like we successfully recorded about 9 to 10 days of wind data in the stratosphere over Antarctica!!
Very pleased to announce that Souleymane Cissokho is joining our research group for the Spring semester 2025! Souley joins after completing his undergraduate degree at Rose Hulman and with experience in acoustic signal processing from Idaho National Labs. Very glad to have him on board! He will be working on acoustic sensing technologies.
Our JTech paper on the 2022 New Mexico high altitude balloon flight has published! Great job to lead author Tim Cheng!
