1. A generator system adaptive, cooling-oil lubrication system, comprising:

  • a primary reservoir compartment and a power generation compartment in fluid communication with said primary reservoir compartment, said primary reservoir compartment being adapted for receiving from and pressurizing through an oil line to said power generation compartment, a cooling-oil lubricant;

    a power generation section of said power generation compartment including means with a rotor rotatingly coupled to stationary means having a rotating electric field for producing electrical power generation output for said power generation section;

    pump means for scavenging the cooling-oil lubricant at a plurality of indices of gravitational orientation for said primary reservoir compartment in order to pressurize the cooling-oil lubricant for forced return to said power generation compartment during operational cooling and lubricating of vital rotational and electrical components of said power generation section when fluid pressure and volume is within an established operational range;

    a residual reservoir section of said power generation compartment in a casing adapted to cause primary recirculated fluid passage of the cooling-oil lubricant from said pump means, said casing having a plurality of fluid communicating passages for collecting and distributing a limited preselected volume of the cooling-oil lubricant to vital rotational components of said power generating section, the limited preselected volume being supplemental to a returnable primary fluid portion in the casing passages during normal fluid pressure operation of said power generation section, and the limited preselected volume of fluid being available for slinging the fluid to said communicating passages by rotor reaction during a fault or failure mode when the fluid pressure operation ceases,said rotor means thereby imparting an energetic release of the cooling-oil lubricant to replenish a portion of said fluid communication passages for continuously recollecting and redistributing the limited preselected volume of cooling-oil lubricant, which remains available during a fault or failure mode to vital rotational and nominal electrical components, without returning the cooling-oil lubricant to the primary reservoir compartment.
