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
The pressure is on to reduce fuel burn for gas turbines of all types. The need is particularly acute for aircraft engines, in that fuel is a large component of operating costs of an airline, so much so that even the volatility in its price can mean the difference between profit and loss. So when airlines demand more fuel efficient aircraft, much of that requirement is passed along to the engine manufacturers. While reducing gas turbine fuel burn is a primary driver, carbon emissions are related, so reducing the fuel burn “kills two birds with one stone”. Continue reading
The first issue of the ANSYS Advantage magazine for 2013 is now available for your reading pleasure… and it focuses on the aerospace industry. Our subject is especially timely, since the aerospace industry is poised to kick off another record year: OEMs (including Boeing and Airbus) as well as the supply chain (such as GE Aviation and Pratt & Whitney) have record backlogs of orders. I’m proud to be involved in putting this magazine together. The publication involves a huge effort from our customers and our staff, so I congratulate and thank them for an excellent job.

I’ve always been passionate about aircraft. When I served in the Air Force and took my pilot training, I learned a lot about how systems on military planes work. One of the most amazing components, to me, was the ejection seat, probably one of the most complex pieces of equipment on board.
Even if the purpose of the seat is clear and simple — to provide the pilot a safe and immediate way out of the aircraft in case of accident — its job is a very tough one. The seat has to work in emergency conditions; it represents the last chance for a pilot to leave a severely damaged aircraft, maybe spiraling out of control. This system must be designed not to fail despite the critical, varied and unpredictable conditions in which it will be used. That’s quite a challenge for designers! Let me give you an example.

The headlines have been filled with the Boeing 787 Dreamliner, a revolutionary vehicle hailed as the airliner of the future. The Dreamliner uses a phenomenal amount of electricity to power many of the systems on board — and that power is supplied by huge and complex lithium-ion (li-ion) batteries. This week, aviation authorities around the world ordered airlines to stop flying their Boeing 787 Dreamliners due to the fire risk associated with battery failure.
While experts everywhere are weighing in on the possible causes, solutions and consequences, we at ANSYS have confidence that Boeing’s engineering, research and technology teams will rapidly and thoroughly resolve the issues, and history will show that this was merely a blip in the overarching aircraft development process.
