Pitot tubes are used to measure airflow velocity, but advanced tunnels deploy laser anemometers that detect wind speed by "seeing" airborne particles in the airstream. Pressure probes monitor air pressure and water vapor pressure sensors track humidity. In addition to sensors, visual observations ...
“The monopiles made by SiF Netherlands are enormous,” says Kaimes, referring to the steel foundation tubes that are piled into the seabed to support the weight of the wind turbine and withstand the forces exerted by wind, waves, and currents. “They are eight metres in diameter, and dep...
In T-Mount setups, the propeller is secured to the motor bell usingtwo small M2 screws. The motor shaft, typically1mm or 1.5mm in diameter, helps center the prop. The lightweight design is ideal for smaller, less powerful drones. It offers a secure fit without requiring large threaded sha...
Before choosing a motor, it’s important to have at least a rough idea of the size and weight of the drone you plan on building. I’ll walk you through the process of determining motor size based on the drone you are trying to build, but if you’re focusing on building a 5″ FPV ...
If you work with electronics and electrical systems, chances are very good you've heard about -- and likely own -- a multimeter. But to give the rest of us a little background, a multimeter is a handy device that's able to measure a wide range of parameters in the world of all thi...
chemicals are pumped through tiny jets into a chemical bath where the plastic coagulates and solidifies into fibers. The spinning step is important, as it helps in directing the internal atomic structure of the fibers. The fibers are then washed and stretched to the desired fiber diameter. ...
To determine the size variation, pitch diameter of the internal thread was measured after each assembly. Ten different manufacturers of 0.5-13 UNC setting plugs were used to set ten different manufacturer's adjustable ring for both GO and NOT GO gages. The fit was controlled between 15 and ...
