For over 100 years, propellers have been the propulsion method of choice for aircraft, helicopter, and boat manufacturers. With the rise of multi-rotor technology, the limitations of this ancient method of propulsion have placed a glass ceiling on emerging industries such as drone delivery and “flying cars.” Besides the obvious safety issues, the faster that a blade rotates the more inefficient it becomes at transferring energy into thrust. A key reason for this upper limit on economies of RPM is that the faster a blade spins, the more prominent the vortex geometry becomes in the mass flow, which is parasitic to propulsion. This constrains both payload and range.Read the rest of this entry »
Engineering is a pretty exciting place to be right now. There seems to be amazing news about new products and technologies being tested and released nearly every day. ANSYS 18.2 just launched and it’s packed with cool stuff. ANSYS Mechanical has a raft of new capabilities to help engineers make new technologies a reality.
I’m amazed at some of the commercial space industry achievements going on right now and of course, being a big car fan, the technology going into the automotive sector is just incredible. In order to bring these products to market, big changes are taking place in the companies designing these products.
More efforts are being put into every aspect of product design and the drive to build better products faster means increased pressure on engineers.Read the rest of this entry »

Smoking meat (and other food) in a barbecue smoker doesn’t sound complicated, but there are more factors at work in producing delicious food than you would expect. Barbecue enthusiast Travis Jacobs, president of Jacobs Analytics, was aware that in windy conditions the air flow through the bottom inlets and the top outlet vents of a smoker can be variable, leading to internal temperature gradients and swirling air that removes smoke and makes a less savory product. He wanted to make a smoker that could smoke food to perfection in any conditions. Unlike most of us non-engineer weekend barbecuers, he turned to computational fluid dynamics (CFD) simulations to solve this problem.

As only China can do, a tremendous amount of engineering talent is supplied at low cost. Combined with the lower cost of materials and manufacturing, how hard can it be to see a market leading product — whether it is a 3D printer, a CNC machine, an automobile or an airplane — produce another one that performs just as well, if not better.
China. 2nd biggest in land area. But with the biggest population (1.2 billion) and a unified will unencumbered by democracy, is there any stopp…

If you’re not familiar with topological or topology optimization, a simple description is that we are using the physics of the problem combined with the finite element computational method to decide what the optimal shape is for a given design space and set of loads and constraints. Typically our goal is to maximize stiffness while reducing weight. We may also be trying to keep maximum stress below a certain value. Frequencies can come into play as well by linking a modal analysis to a topology optimization.
Why is topology optimization important? First, it produces shapes which may be more optimal than we could determine by engineering intuition coupled with trial and error. Second, with the rise of additive manufacturing, it is now much easier and more practical to produce the often complex and organic looking shapes which come out of a topological optimization.Read the rest of this entry »
