Accurate Spray-Wall Interaction Predictions with ANSYS Fluent 16.0

Computational Fluid Dynamics (CFD) has become an integral part of product design and development. Today, CFD is extensively used across industries like Aerospace, Automotive, Marine, Oil and Gas, Electronics, Health care, Process and Infrastructure. While CFD tools provide detailed engineering insights and shorter product development cycles at reduced cost, CFD community is constantly working hard to improve accuracy, speed and ease of use of these tools. Complex physical phenomenon such as detailed chemistry, primary atomization, electro-chemistry, icing formation are constantly investigated and newer, better and accurate numerical models are introduced in CFD tool.

Springing into the Future of Aerospace Transport

The recent and very significant fall in oil prices has been very welcome as far as the cost of heating is concerned. Sure the days are becoming perceptibly warmer and there is a feeling that we have finally turned the corner from Winter to Spring. While I personally welcome the reduced expenditure, I am glad to see that this recent downward shift in oil prices has not caused the aerospace industry to lose focus on the long term, interconnected objectives of reducing fuel usage and environmental impact.

DO-178C – Aeronautics Industry Moves To New International Software Safety Regulation

Embedded software in today’s aircraft is becoming continually larger and more complex. For example, the volume of embedded software in the A300 was a few thousand lines and it is in the order of 100 million in the A380. Moreover, a sizeable part of this software is safety critical. Hence, delivering certified code is one of the critical path design elements that is growing in significance. Continue reading

Don’t Call Them Blimps!

Many of us based in North America were glued to the screen recently to watch the annual Super Bowl event. Almost synonymous with this sporting extravaganza is the Goodyear Blimp. But this isn’t confined to the Super Bowl. You will find these lighter than air vehicles in the sky above almost any major sporting event around the globe. Not only do they add to the spectacle but their long loiter capability contributes significantly to the coverage we all enjoy. Continue reading

ANSYS Adds Aircraft Icing Simulation

aircraft icing simulationLast week, I was preparing for a visit to customers in the Washington DC area. This involves only a short flight from my office in New Hampshire. Then came winter storm Juno and with it myriad flight cancellations — and the end of my trip before it had even started. While these events can be frustrating at the time, the priority is obviously safety. It is because aircraft designers and airline operators follow strict aircraft certification guidance from the US Federal Aviation Administration (FAA) and other regulatory bodies that air travel is as safe and reliable as it is today.

What Does Stephen King Have to do With Systems Engineering and AIAA SciTech 2015?

Those of you familiar with the writing of Stephen King may find talk of being under the dome a little disconcerting. And this time we are talking about not just one dome, but two – an alpha and a beta. But rest assured, this is not a spooky science fiction story, this is science fact and the Systems Engineering Simulator facility, which contains the two test domes at NASA Johnson, is a very practical demonstration of the significant benefits to be gained by the application of systems engineering, hardware and virtual hardware in the loop simulation. Using these facilities, engineers and scientists can prove out design concepts and operations in a virtual environment before risking a mission in space. The benefits are clear and include risk mitigation, cost reduction and design cycle compression. Continue reading

Why Antares Launch Failure Isn’t a Failure

Pushing the frontiers of space exploration is risky business. One thing that history has taught is that setbacks remain as inevitable as successes. Indeed it could be argued that the setbacks are a necessary component of the successes. That’s one indispensable truth we all can take away from Tuesday’s Antares launch failure on Virginia’s Eastern shores. It doesn’t dampen the exciting frontiers we envision when commercial interests, as well as policymakers, propel forward space exploration. Newscasters can play Monday morning quarterback on the failure of the Orbital Science launch, in which nobody was killed or injured, but they’ll be in a tough spot if they try to deny that this is anything more than growing pains in the emerging commercialization of the space industry.

When Universities Fly High – University of Naples

20140226_135427 (1)We are pleased to present a guest blog from Giovanni Paolo Reina and Angelo Della Sala at the University of Naples.

The weapon-aircraft integration is one of the most important aspects in military aircraft design and for the study of its performances. In particular store separation problems, i.e. problems related to the release of underwing bodies during the flight, are very critical because they occur during a flight operating condition.
