In der Flugzeugentwicklung werden numerische Strömungssimulationen zur Verbesserung der Aerodynamik schon lange eingesetzt. Doch sie können auch zur Verringerung von Fluglärm beitragen.
Mit dem weltweiten Anstieg des Luftverkehrs zeigen sich einige neue Herausforderungen bei der Entwicklung moderner Flugzeuge. Denn das immer weiter erhöhte Flugaufkommen führt zu großen Lärmproblemen, vor allem bei den Anwohnern städtischer Gebiete im Start- und Landebereich. Daher muss das Design künftiger Flugzeuge neben Effizienz und Kostenersparnis verstärkt auf die Geräuschentwicklung hin untersucht werden.
Exa Corporation explains how transient flow simulations can enable more realistic reproduction of real-world conditions for accurate assessment of fuel economy
For a typical car driving at highway speeds, about 50% of the energy is spent overcoming aerodynamic drag and the other 50% is required to overcome the mechanical losses (engine, transmission, tires, ancillary systems, etc.). This means that every 2% in aerodynamic drag reduction translates to a 1% improvement in fuel economy.

A study has revealed that several carmakers are likely to incur fines of hundreds of millions of euros by missing EU-mandated emissions reduction targets.
According to an analysis by PA Consulting Group, five European car firms will miss the targets set by the EU, which require new car fleets to not emit more than an average of 95g of CO2 per kilometre.
Exa® Corporation (NASDAQ:EXA), a global innovator in simulation software for product engineering, today announced that the company will host a live webcast of its Analyst and Investor Day on Wednesday, December 14, 2016. Exa's management team is scheduled to begin presentations at 9:30 am ET and to conclude at approximately 1:00 pm ET.
"We continued our momentum in the third quarter and delivered revenue that was in the middle of our guidance range and profitability that was above the high end of our guidance range," said Stephen Remondi, President and Chief Executive Officer of Exa. "With license revenue increasing 14% from a year ago, we continue to drive a shift in mix to higher-margin, recurring license revenue. Strong renewal activity in the quarter sets us up for a healthy finish to fiscal 2017 and start to fiscal 2018.
It can be as loud as standing alongside a Boeing 767 at takeoff. And it’s about as irritating as having someone thumping on a bass drum in the back seat. Whether you call it wind throb or buffeting or just plain annoying, it happens when someone in the car opens a single window at speed and it stops when a second window rolls down.
Fuel-consumption targets and emissions legislation, combined with the relative maturity of engine and bodyshape designs, are forcing commercial-vehicle manufacturers to find innovative new ways to improve the efficiency of their vehicles – and one of the latest technological developments in their armoury is digital simulation.
Indeed, testing systems in a virtual environment is now a key tool in the development of more fuel-efficient and eco-friendly vehicles.
Seit wir leistungsfähige Computer nebst entsprechender Mathematik haben, helfen uns Simulationen, unsere Welt vom ganz Großen bis ins Kleinste besser zu verstehen. Wenn wir "Simulation" hören, ordnen wir den Begriff schnell ein zu "das zweitbeste nach Realität", weil es unserer Lebenswelt entspricht. Motorradfahren. Sex. Fußballstadion. In vielen Bereichen jedoch hat sich die Simulation als der Realität weit überlegen gezeigt. Manchmal kann man die Realität nicht so zum Experiment gestalten, dass wir sinnvolle Ergebnisse erhalten.
Exa® Corporation (NASDAQ:EXA), a global innovator in simulation software for product engineering, today announced that it will release its financial results for the third quarter of fiscal 2017, ended October 31, 2016, after market close on Wednesday, November 30, 2016. On that day, management will hold a conference call and webcast at 5:00 p.m. ET (2:00 p.m. PT) to review and discuss the Company's results for the third quarter of fiscal 2017.
Since the recent Tata-funded Jaguar Land Rover (JLR) rebirth, Jaguar has had its chance to shine with XE, XF and F-Pace; Range Rover had its starring role with both Range Rover and Range Rover Sport SUVs; and now its Land Rover's turn with the all-new much light, tech laden and more luxurious Discovery.
The 2017 Land Rover Discovery is being hailed for its sleek design and what’s under the hood, but its major accomplishments—shedding 1,000 pounds and becoming more aerodynamic—wouldn’t have been possible without serious horsepower in the form of virtual testing and simulation.

If Tesla wants its planned electric truck to come with enough range that is acceptable to haulage fleets, it might need to accelerate research into platooning. Platooning is when smart trucks connect digitally to travel in close convoy, in order to improve overall fuel economy.

At the 2016 Paris Motor Show, Jaguar Land Rover (JLR) showcased its new Discovery – a seven-seater SUV that will go on sale in spring 2017. It includes a number of striking design choices, like the lightweight aluminium construction that saves 480kg and is a key contributor in reducing CO2 emissions by 22% compared to the previous generation.

This year’s Paris Motor Show was full of superfast concept cars and innovative technology, but the Land Rover Discovery was still one of the most important cars unveiled in the French capital last week. Although it looks pretty conventional on the outside, it was developed using sophisticated simulation technology that you’d usually associate with F1.
In the past, cars were built almost by a process of trial and error. You built a prototype, then tested it to find out what worked and what didn't. Nowadays, much of this work is done by computers.
Theo Leggett has been talking to Stephen Remondi, chief executive of Exa Corporation, to see how 3D simulations are being used by designers to refine their work in the virtual world before a single car panel has been built in the real one.
JaguarLandRover engineers continue to achieve significant vehicle mass reductions, this time with the new generation Land Rover Discovery. Shifting to aluminum construction for the bodyshell instead of steel and complemented by an intensive light weighting program for the whole car, has yielded a remarkable 480 kg (1,058 lb) saved compared with the previous model. This exceeds even the 420kg (925 lb) reduction of the Range Rover in 2012 when it was switched to an aluminum-intensive architecture.
Reinventing the wheels: Tesla Model 3
The wheels on the forthcoming electric sports sedan direct air under the body. Tesla uses aero simulation tools from Boston-based Exa, and the computer-aided wheel design would reduce the need for expensive active aero devices, thus cutting costs.
Onroak Automotive a dévoilé ce vendredi à Spa la Ligier JS P217 qui arpentera les circuits du monde entier dès la saison 2017.
