Innovative V-Band Clamp Nut Keeps Turbochargers Sealed

V-Band Clamps encounter many extremes. When it comes to turbochargers, which are increasingly used in light trucks and cars to deliver the power of a V8 engine in a V6, the clamps seal off hot exhaust, forcing compressed air into the intake. The result is lighter vehicles and better fuel economy. But component temperatures around

Using sodar in complex terrain

Editor’s note: This article comes from sodar manufacturer Second Wind Measuring wind in complex terrain is becoming increasingly critical as more of the ideal, flat, windy sites available for windpower are developed. Ground-based, portable remote sensing is ideal for measuring wind in complex terrain because it’s hard to put up towers, and developers can measure […]
