You'd think measuring an engine's displacement would be simple, but there's a long history of trying to figure out how to categorize the Wankel.

We all know the age-old maxim, "There's no replacement for displacement." It's the truth. That's why so many sanctioning bodies use displacement and compression rules to limit engine power. Of course, ...

Laser Doppler vibrometers (LDVs) measure vibrations in ways that other sensors can't. From large aircraft structures to microscopic MEMS sensors, and vacuum enclosures to red-hot mills, LDVs measure ...
