Hydrostatic Drive for Winch & Mooring System of Aerostat
Hydrostatic drives are widely recognized as an excellent means of power transmission when variable output speed is required. They offer fast response, maintain precise speed under varying loads, and allow infinitely variable speed control from zero to maximum. Unlike other mechanical transmissions, hydrostatics have a continuous power curve without peaks and valleys, and they can increase available torque without shifting gears. Hydrostatic drive technology is used to develop winch and mooring system for medium size Aerostat whose purpose is to raise, lower and hold the balloon. It contains a pressure compensated, load sensing variable displacement axial piston pump, Hydraulic actuator, proportional valve bank and all required controls in one simple package. Such a system provides all the noted advantages of a conventional hydraulic system. It has been designed for raising and lowering the Aerostat at the speed of 75 m/minute at 3400 kgf load and it can sustain a load up to 10T load.
