Lightning Strikes Airplane – Clever Engineers Save the Day

Earlier this year we experienced a quite severe storm with thunder and lightning here in New Hampshire in the US. While this is not in itself unusual, it sticks in my mind because it brought a tree down on my garage. Fortunately the damage was only superficial, no one was hurt and it was repaired relatively quickly. However, since then I pay a bit more attention either during storms or when I read about the effects of them in the press.

If you watch the video below, I think you will agree it is spectacular and also a little frightening, particularly if, like me, you fly extensively. Continue reading

Defense Technology and A Coat of Paint: The Difference Between Winning and Losing

Defense technology news has been awash recently with stories of the defeat of the Lockheed Martin F35 Joint Strike Fighter during a dog fight with a 40 year old fighter, the F16. Of course, such sensational stories are to be expected for an aircraft program that is under the microscope, particularly when it is alleged that the test pilot stated that the “F35 is at a distinct energy disadvantage” when it comes to maneuverability.

But just as quick was the response from the F35 team. According to the Washington Post, Pentagon officials pointed out that one of the key technologies that was missing from the F35 that was tested in the dog fight was its “special stealth coating” — or literally an extra coat of, albeit very expensive, paint.

Monthly Healthcare Webinar: Sharing Knowledge to Innovate Faster

This is very frustrating. I have the chance to travel quite a bit and meet with numerous medical partners —academic leaders, industrial experts, thought leaders and medical device executives. Many of them are as passionate as I am about using simulation to accelerate the pace of innovation for medical device and pharmaceutical solutions. Yet, most of them are amazed when I show them some of the achievements of their peers. Some simply didn’t know that this application or model was possible to simulate or didn’t know how to do it .If all of them would share great results in their areas of expertise then everyone could learn and benefit.

This is not acceptable for an industry where our pace of innovation means better comfort, less pain or perhaps survival for the patient! Continue reading

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.

raymond wang intel science fair winnerYet perhaps, I am best known for my most recent project, which won the 2015 Intel International Science and Engineering Fair, out of 1,700 students nationally selected from 75+ countries. 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%.
