value developed by each independent channel should be identical should some of the equipment fail a single channel would be sufficient to continue operations until repairs can be made additional levels of redundancy can also be superimposed in addition to these two redundant channels in accordance with the embodiment of fig5 controller 111 receives monitoring signals from transformer resolver 217 and transmitter resolver 251 from one portion of drive shaft 201 and also receives and monitors signals from transformer resolver 253 and transmitter resolver 251 from another portion of drive shaft 201 controller 111 combines the data in a manner which provides the two independent measurements of the twisting load on drive shaft 201 fig6 is a pictorial and schematic representation of the mechanical components which are utilized in interconnect drive train 301 which mechanically links pylon conversion actuators 303 305 and which is utilized to measure load sharing between the pylon conversion actuators 303 305 as is shown in the view of fig6 the pylon conversion actuators 303 305 terminate at an opposite end with a fixed lug 307 309 on each pylon conversion actuator 303 305 a telescoping ball screw 311 313 is provided as is shown the mechanical systems are symmetrical they include a bevel gear set 315 spur reduction gears 317 and a hydraulic clutch 319 each rotor assembly has associated with it a planetary differential 321 each is mechanically driven by primary hydraulic power drive unit 323 and is braked by primary hydraulic.
