CANTON Over the past 15 years C. Mitchell Boulton has been working to make something old new again. Doing what he described as a retirement hobby, Boulton began reverse engineering a radial aircraft ...

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 ...

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, ...

Honda might be looking back to early aeronautics in its latest bid to make variable compression engines simpler and sturdier. The engine is designed to take advantage of the simple crank design of ...

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 ...

Matt Nelson is an automotive journalist with nearly a decade of experience in all things cars. He's spent years working at dealerships in sales, finance, and service. He's since traded in his pens and ...

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 ...

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.

Click to open image viewer. The XR-7755-3 is the largest, most powerful reciprocating aircraft engine in the world. During World War II, the U.S. Army Air Forces requested an engine with high takeoff ...
