When learning about the design of a machine or mechanism, reading and watching videos is certainly effective, but it’s hard to beat hands-on experimentation. In the video after the break, [Brick ...

Everyone generally knows about piston and rotary engines, with many a flamewar having been waged over the pros and cons of each design. The “correct” answer is thus to combine both into a single ...

During World War II the radial engine was popular, and it was used in many fighter and bomber aircraft. Manufacturers in aviation used them because the engines deliver a ton of power for their size, ...

Like all good engineers, those designing aircraft engines are greedy. They always want more power, more durability, and more efficiency. They also want it in the smallest, lightest package possible.

German researcher Otto Lutz introduced the swing-piston concept about 1923. Intended primarily as a high pressure compressor or gas generator for relatively high power gas turbine engines for ...

While the bright yellow fuselage has been restored, it’s the front section of the biplane that’s unique. A turboprop engine has replaced a radial piston engine. It’s the work of Turbines Inc., which ...

As the automotive propulsion industry shifts toward electrification, the last-of-breed combustion engines are a stultifyingly similar bunch, focused around the same CAD-optimized 500cc cylinder ...
