Flows around aerodynamic bodies, like aircraft wings, helicopter blades, wind turbines and turbomachinery components develop boundary layers that, to a large extent, define their performance. The boundary layers can either be laminar or turbulent depending on numerous factors, like Reynolds number, freestream turbulence levels and surface roughness, to name a few. Understanding which type of boundary layer is present, and the location of the laminar-to-turbulent transition point under varying operating conditions, is essential for accurate predictions of the performance of aerodynamic devices.

Drones have been in the news a lot recently. The near miss between a commercial flight and an unidentified drone in Florida has been broadcast around the world and has opened lots of questions about how the issue of drones in civilian airspace will be handled as the number of drones increases exponentially. This has spawned discussion regarding the safety of aircraft in the event of a collision with a drone. What is for certain is that the FAA have got their work cut out to ensure the safe management of the exponential growth of the drone phenomenon. Continue reading
In today’s ultra-competitive environment, product differentiation increasingly depends on embedded software. From automobiles to airplanes to medical devices, systems architecture and embedded software are important parts of product development cycles. Being able to manage these processes effectively so that you get the desired results is becoming a differentiator.
Today, the cars that we drive have more that 10 million lines of code! Can you imagine the hours it takes to come up with the definitions of what the car should do and how it should do it — let alone implement all this correctly through software code? It’s a time-consuming process, and getting it right the first time is challenging. We’ve all seen examples of what happens when the code isn’t correct. Incorrect code can cost companies millions of dollars, and more importantly, it erodes customers’ trust in that brand.
By using model-based, production-proven software tools for the development of embedded code, products can be developed in a faster and safer manner. And, when coupled with a certified automatic code generator, compliance for standards like DO-178B/C in aerospace, ISO 26262 in automotive and EN 50128 in rail is more rapidly achieved.
