Investigating Placement of Antennas Inside an Aircraft Fuselage

You may be surprised to learn that a standard passenger jet can have 30 to 50 antennas protruding from the aircraft’s external surface, producing drag forces that can drastically reduce fuel efficiency at a time when airlines are trying to reduce energy consumption. Most antenna designs are engineered for safety purposes, such as air traffic control, traffic collision avoidance, instrument landing systems and distance measuring equipment. Increasingly, antennas are being added to meet passenger demand for more and faster Wi-Fi access, in-flight TV and cellphone applications.

Startups Bring Excitement to Established Industries

Startup companies are using ANSYS software in exciting and groundbreaking ways. It should come as no surprise then that some of my favorite articles in our ANSYS magazines (ANSYS Advantage and Dimensions) in 2017 were generated with the assistance of startups. I think the enthusiasm of these hardworking teams of entrepreneurs who participate in the ANSYS Startup Program is demonstrated in these articles about how their pioneering products are being developed.

Many startups literally begin in a garage. For example, Kyle Doerksen, Founder and CEO of Future Motion, inventor of the Onewheel motorized skateboard, prototyped his idea in his garage before launching a Kickstarter campaign. With the help of engineering simulation his team quickly moved from prototype to mass production. Future Motion has shipped more than 10,000 products, expediting many short commutes and creating a new form of transportation and recreation along the way.

Ensuring EMI/EMC Compliance with Electronics Simulation

Today we live in a hyper-connected world, surrounded by smart products. If industry forecasts are correct, by 2020 — just 2 short years from now — there will be over 28 billion internet-connected devices. Beyond smart phones and autonomous vehicles, smart cities, smart factories, and smart homes are also quickly emerging as promising opportunities that could help improve how we live, work and play.

While these new capabilities will be a delight to us as consumers, they are a nightmare for engineers and product designers. With hundreds of sensors, microprocessors, and wired and wireless communication components, engineers face immense challenges in ensuring reliability and performance. In the complex web of electronic circuitry, something, somewhere that is left unaddressed could lead to failure. One of the big challenges confronting product designers is electromagnetic interference, or EMI.

Pervasive Simulation for Electronics in ANSYS Advantage

ansys advantage electronicsElectronics are everywhere. Amazing innovations such as driver assistance systems (ADAS), IoT, 5G communications, hybrid propulsion and others all depend on electronics. Engineers and designers in almost every industry, must account for electromagnetic fields to design, optimize and deliver products quickly to market.

As radio frequency (RF) and wireless communications components are integrated into compact packages to meet smaller footprint requirements while improving power efficiency, electromagnetic field simulation is the only way to make these trade-offs.  Simulation enables innovative ideas, that can push products beyond their traditional limits, to be tested and realized without the burden of prototype costs and time.

The latest issue of ANSYS Advantage features articles from industry leaders who make the most of electromagnetic field simulation to develop next-generation products and deliver them to market quickly.

Structural Simulation Delivers Modular Wi-Fi Towers Quickly

Wi-Fi access today seems more like a right than a privilege. But easy access to Wi-Fi is not widespread in many countries, especially in out-of-the-way rural areas where structural design and building of Wi-Fi towers can be challenging. In the interior of Brazil, only 22 percent of the people have Wi-Fi due to the costs of installing towers and the economics of providing service to sparsely populated areas. But startup Jet Towers is trying to remedy this situation using ANSYS AIM for structural simulation to design prefabricated, modular truss towers that can be installed and running within a week of purchase, instead of the normal five weeks for custom designed Wi-Fi towers.

ANSYS Advantage: Simulate Early for Successful Products

ANSYS Advantage Issue 2 2017The vast majority of engineering decisions are made without the insights that engineering simulation could provide into the impact of those decisions. It is estimated that 80 percent of the total product development costs are locked in by choices made early in the design process — and subsequent analysis and optimization now has to live within the implied constraints or face very costly and time-consuming design changes.

With increasingly complex products taking advantage of advanced materials, additive manufacturing and IoT, this issue will grow exponentially as many more permutations and design options must be evaluated for any given product. The only way to harness the potential of these mega trends, and tame the inherent complexity, is to bring simulation upfront in the product development process. To design the products of tomorrow, leading companies are doing exactly that.

Pump Simulation Advances with ANSYS 17.0

Pumps are pervasive and play an important role across many industries and in our daily lives. They have been around for a long time, when you consider that the Archimedes screw dates back over two thousand years. They come in a wide range of sizes and styles, from heart pumps that measure only millimeters in size to large pump-turbines that measure meters in diameter. Some pumps are custom- engineered and very high-tech, such as those used for liquid rocket propulsion, nuclear submarines or power plant applications. Many others are regarded as a commodity items, although that view is changing, as we shall see. Some estimate that pumps consume as much as 10% of the electricity generated worldwide.

ANSYS Advantage: Spotlighting Process Compression

Around the world, businesses, no matter what the industry, are facing similar challenges:

  • Customers demand compelling products delivered on more frequent cycles.  
  • Products have become a complex mixture of mechanical, electrical and embedded software systems.  
  • Global markets offer more opportunity, but also more competition.

To remain competitive, companies must deliver innovative products to market faster and at a lower cost. But the pressure to innovate more quickly and move even faster is relentless. Simulation has long been a valuable tool to verify designs and reduce testing, saving both time and money, but using simulation towards the end of the product design cycle is no longer sufficient.  Continue reading
