Abstract:
Simulation techniques have been developed to determine oil circuit flow rate, pressure, and temperature throughout a Variable Speed Constant Frequency (VSCF) electrical power system. This data can be used to indicate if a VSCF system is adequately cooled and lubricated throughout an aircraft flight envelope. A combination of spray-oil and conduction cooling is an effective means of dissipating heat, and provides for lubrication within the same oil circuit. Cooling effectiveness increases with oil flow rate, but a higher flow rate also increases pumping power consumption and lowers VSCF generator efficiency. Oil circuit simulation can be used to optimize flow rate; the result is more efficient VSCF systems, shortened design times, and reduced product development test time.
