Dr. Krish Ahuja, Regents Professor at Georgia Institute of Technology (Georgia Tech) helped attendees at the eighth annual Electric Aircraft Symposium understand an unusual set of problems by starting off with an explanation of acoustics for non-acousticians.  His credentials, impressive as they are, are more than matched by his ability to help those outside his specialty understand his discipline. According to his Georgia Tech web page, “Dr. Ahuja is a former associate editor of the AIAA Journal and also a former Chairman of the AIAA Aeroacoustics Technical Committee. Dr. Ahuja has authored or co-authored over 180 technical articles or reports on a range of topics including acoustic shielding, fan noise, active flow control, flow/acoustic interactions, jet noise, cavity noise, automobile …

In a series of far-reaching competitions for university students, the FAA has opened the gates on innovation for new aircraft and airport infrastructure design. Announcing the winners of its Design Competition for Universities, the FAA awarded three prizes in the Electric/Hybrid Electric Aircraft Competition.  In doing so, it acknowledged the pioneering work of the CAFE Foundation and NASA in promoting the original Green Flight Challenge, generously supported by sponsorship from Google. “Recently, the Green Flight Challenge and efforts of general aviation manufacturers and others have demonstrated flight using electric motors on general aviation aircraft. Under NASA’s Subsonic Fixed Wing Project, aircraft and engine manufacturers identified key technology capabilities required for electric and hybrid-electric propulsion of single aisle aircraft, expected by …
