Drive Shaft in Kite Energy
Torque Transmission

• How do driveshafts play in some kiting applications?   The driveshafts transmit torque.
• Torqued tethers sometimes occur when not wanted. These scenes may be explored.  Tether rotations
• Universal joints, swivels,
• Cased driveshafts
• Uncased driveshafts
• Gears
• Shafts of rotors come in many diameters and lengths.
• What drives the rotation of the drive shaft?  
• What is driven by the rotation of the drive shaft?
• Uncased rope or cable as driveshaft
  • SkyMill (Italy)

  Comment: "Note- a drive-shaft/torsion-tube is a high-compression structure that presses hard on its core under load. Most of the weight is solely to fight this compression, either by a solid core, or by a rigid tube section. Buckling failure is more likely given the vagaries of service, but a torsion-tube can actually implode under load.  13Oct2010 ds"
