What do Facebook, Boeing and Raytheon Have in Common?

Apart from the fact that Boeing and Raytheon, like most companies in the world today, use social media and have a Facebook page, what at a core product level do these three companies have in common? Not a lot you might think. Well think again.

Facebook recently announced that it is building an aircraft (video) that has a similar wingspan to a Boeing 737. What is more, when flying at 60,000 ft. this aircraft will be able to transmit information over 10 miles using lasers to hit a point no bigger than a dime at a data transfer rate in the 10s of Gigabits per second. Right in the domain of expertise of companies like Raytheon. Talk about the convergence of the Internet of Things and the aerospace and defense industry! Continue reading

Composites? Not as Lame as Some Would Have You Believe

Like many others, I am delighted to see the progress made over recent years by some of the major aircraft manufacturers to deliver significant improvements in fuel efficiency and associated environmental impact. Popular media examples are the Boeing 787 Dreamliner and the Airbus A350. Improving the performance of aircraft like these involves almost every system and component of the aircraft from the engines, aerodynamics and aerostructures to the vast array of power, mechanical, pneumatic and hydraulic systems and beyond. It cascades from the OEMs right down through the supply chain.

At the recent Paris Airshow, some Boeing test pilots dramatically demonstrated exactly what can be achieved with these new aircraft. Breathtaking.These truly are game changing aircraft. Continue reading

Never a Dull Moment in HPC – Trend Report

young man looking for a way out of a boring job

When one of my friends asked me on Saturday night what I like about my job, I started off by saying that “there is never a dull moment in HPC. The computing landscape is constantly changing, the HPC ecosystem collaborations are so numerous and intriguing, and the strategic/economic value of HPC for simulation has never been greater” (or: relevance of HPC for organizations to become more competitive is so compelling).

All of this was very evident at last week’s ISC conference — one of world’s largest HPC events — drawing this year over 2,800 attendees from 56 countries. Let me share with you a few exciting HPC trends observed during this conference.

ANSYS Campus-Wide Solution Expected to Spur FIU Research Output

ANSYS team during the signing ceremony at FIURecently an ANSYS team was invited to attend a signing ceremony at Florida International University (FIU). The signing ceremony was to formalize ANSYS’ donation of a campus-wide license to FIU and to recognize the generous contribution.

The visiting team included Sin Min Yap, Vice President, Bob Helsby from the ANSYS Academic Program and Ryan Bobryk, Account Manager at ANSYS. They first toured the FlU campus visiting various research labs and departments. The team returned overawed with the fascinating research projects at FIU and shared their excitement with colleagues at ANSYS. Continue reading

AIMing for Better Biomedical Devices

Earlier this year, we introduced ANSYS AIM, the first integrated and comprehensive multiphysics simulation environment designed for all engineers. Check out Richard Clegg’s recent blog post for an overview.

Since then, we’ve been applying AIM to a wide range of industrial applications, including the medical device industry, where AIM provides a modern, easy-to-use tool for a variety of applications. Continue reading

Aircraft Cabin Airflow: Curbing Disease Spread

For me, science and engineering has always been about designing solutions to the various problems in our everyday lives. When I began doing research in seventh grade, my very first project was a roof that converted the impact energy of precipitation into electricity to help power the home. The following year, I came up with a dynamically supportive knee brace that implements smart fluids to vary the amount of support that patients received, depending on the physical activity. Last year, I created a self-cleaning outdoor garbage bin to tackle the issue of urban sanitation in our neighborhoods.

This year, I tackled the issue of airborne pathogen spread in aircraft cabins, generating the industry’s first high fidelity simulations of airflow inside airplane cabins. Using my insights, I engineered economically feasible solutions that altered cabin airflow patterns, creating personalized breathing zones for each individual passenger to effectively curb pathogen inhalation by up to 55 times and improve fresh air inhalation by more than 190%.

Using ANSYS CFD to Analyze High-Lift Wing Design

Agastya ParikhFour years ago, as a high school sophomore, I began work on an independent project that explored ways to improve the performance of high-lift systems used on the Airbus A330-300. One of the biggest challenges facing me was how to best conduct experiments to assess the performance of the different designs. In prior years, I had conducted simple research on aircraft wing design and aeroelasticity using unpowered balsa models of the aircraft being tested. To employ this same method would be unworkable for the relatively complex systems of flaps and slats required by the Airbus aircraft. I would have needed to build a larger scale model or perform wind-tunnel testing — neither of which was viable because I did not have access to equipment of the complexity required. Continue reading

Landing Gear: An Aircraft System We Take for Granted

Watching the news recently I saw a video of an aircraft landing without one of its landing gear fully deployed. Wonderful job by the pilots and crew.

As it turns out, it is not that difficult to find other on-camera examples.
