Recently, when I attended the AIAA SciTech2014 Conference, I was impressed by a talk about electric aircraft, with a focus on distributed electric propulsion, presented by Mark Moore, a Design Engineer at NASA Langley Research Center. After returning from the conference, I started to read more about these concepts — especially looking for the benefits, challenges and most importantly to see how ANSYS simulation tools can help address the challenges.

Passenger CARE and Aircraft Design

A few days ago, while I was waiting to board a flight, I ran into a childhood friend who I hadn’t seen in 20 years, and he was waiting for the same flight. We talked about all the developments in our lives over the last two decades, and it was wonderful catching up. I told my friend about how I had graduated in aerospace engineering, that my specialization is in CFD, and that I get to work with aerospace customers. He was quite interested in learning more about how our software helps with aircraft design.

Just around that time, the announcer issued the boarding, and so we boarded the flight and managed to get seats side by side.

While we continued our discussion, the aircraft was on the tarmac and began acceleration for take off. All of a sudden, my friend grabbed my hand. I was quite surprised and looked at him, even more shocked to see his tensed face with eyes closed and ears filled with cotton. Continue reading
