How does a helicopter work? - Explain that Stuff

Jun 24, 2018 · Vertical pitch links push the blades up and down, making them swivel as they rotate. The pitch links move up and down according to the angle of the swash plates. The rotor mast (a central axle connected to the engine by the transmission) makes the entire blade assembly rotate. The rotor hub cap (above the rotors) helps to reduce aerodynamic drag.

Jun 14, 2007 · Tail rotor The tail rotor is a smaller rotor mounted vertically or near-vertical on the tail of a traditional single-rotor helicopter. The tail rotor either pushes or pulls against the tail to counter the torque. The tail rotor drive system consists of a drive shaft powered from the main transmission and a gearbox mounted at the end of the tail ...

Wind turbine | Open Energy Information

VAWTs typically fall into two main design classes: lift-based or drag-based. Drag-based, or Savonius, turbines generally have rotors with solid vanes ("scoops") that rotate about a vertical axis.A 3-cup anemometer (which is used to measure wind speed) is an example of a drag-based design.

A Dynamic Rotor Vertical-Axis Wind Turbine with a Blade ...

This work presents an optimized design of a dynamic rotor vertical-axis wind turbine (DR VAWT) which maximizes the operational tip-speed ratio (TSR) range and the average power coefficient (Cp) value while maintaining a low cut-in wind velocity. The DR VAWT is capable of mimicking a Savonius rotor during the start-up phase and transitioning into a Darrieus one with increasing rotor radius at ...

Geometrical optimization of a swirling Savonius wind ...

The diameter of the rotor can be calculated using the inside and outside diameters of the blade pipe and the blade overlap ratio from D = OD + ID (1-β) formula. As the end plate diameter is usually made 10% larger than the rotor diameter for the conventional Savonius turbine with optimum performance, the same ratio was applied to the new rotor.

Vertical Angle Centrifuge Rotors - Beckman Coulter

Vertical angle rotors feature the shortest pathlength of any rotor type, the fastest run time, and the highest resolution. In a vertical rotor, tubes are vertical during the run. The short pathlength and low k factors of these rotors mean that the particle has only a short distance to travel to pellet, reducing the run time for the application.

AC Motor | Basic Stator and Rotor Operation Diagrams

The rotor is the rotating electrical component. It also consists of a group of electro-magnets arranged around a cylinder, with the poles facing toward the stator poles. The rotor is located inside the stator and is mounted on the AC motor's shaft. The term "rotor" is derived from the word rotating. The rotor then is the rotating part of the AC ...

Vertical Pump Repair and Upgrade Considerations | Hydro, Inc.

Apr 01, 2010 · The overriding repair concept for vertical pumps is two-fold: establish true centerline compatibility between the rotor and stator at the motor-to-discharge head flange location and ensure that the maximum relative radial displacement of the stator to the rotor-at any point for the pump's entire length of the pump-does not exceed the minimum ...
