Abstract: The system controls the frequency of an ultrasonic signal to be applied to a waveguide, such that the frequency corresponds to a preferred resonance mode of the waveguide and not to adjacent undesirable resonance modes. The system operates by carrying out a first scan of a predetermined portion of the generated signal, determining the number of resonance modes of the waveguide within this portion and selecting from these resonance modes either that one mode which is at a central frequency or that one mode which is at a frequency nearest thereto. The system may also set limits on each side of the selected resonance mode and carry out a second scan within these limits each time that the generator is activated to check whether the selected resonance mode is drifting.

Abstract: An electric generator of the type that is oil-cooled and generally used in aircraft includes a fluid brake assembly. The fluid brake assembly includes a fluid brake rotor which is generally in the form of a fan or impeller which is connected to the drive shaft of the generator. Under normal conditions with the cooling oil withdrawn from the housing of the generator by the scavenge system, the fluid brake rotor freely turns with the shaft. When the oil scavenge system becomes incapacitated, the generator becomes "flooded" and the fluid brake rotor acts as pump to try to pump the oil, creating a torque load on the drive shaft. This load is preferably greater than the shear strength of the shaft, causing the shaft to shear and disconnecting the generator from the aircraft engine. By shearing the drive shaft, the operation of the main engine is unaffected by the flooding of the generator, and serious failure of the aircraft engine is avoided.
