So taking the 3kW produced by the motor, the torque at 1000rpm is: Torque = 3000/(1000/60 * 2 * PI) The torque required for the propeller is simply the power divided by the rotational speed in radians per second.
What would be the full-scale moment Ms according to Froude's law of similarity? (Model scale a=30, Pm= 1000 kg/m', ps= 1025 kg/m). The Woodcomp factory produces more than 150 types of fixed, ground adjustable and in-flight adjustable aircraft propellers at its advanced manufacturing and testing facility in Odolena Voda, Czech Republic, working in wood, composites and metal. When the car is being assembled from the factory the mechanics tighten each nut and bolt per the engineering specifications and when the inspector comes along to check the mechanic's work he will place a liquid stripe across the bolt indicating it has been torqued to the proper value. The calculator accepts angular speed in RPM (rounds per minute) and the conversion to radians per second is a simple.
