摘要： A vibration attenuator (301) for attenuating vibrations in a mast of an aircraft is disclosed. The vibration attenuator comprises a first spinner (215) configured for rotation about a first axis; a first mass (307) coupled to the first spinner for rotation therewith, the first mass being movable radially relative to the first axis between an inner position and an outer position; an actuator (311) coupled to the first mass for selectively controlling a radial location of the first mass relative to the axis; and a first motor for driving the first spinner in rotation about the first axis.

摘要： A method (300) of simulating an aircraft one-engine inoperative ("OEI") event includes operating (302) a supplemental power unit ("SPU") at a first SPU power level less than an SPU contingency power rating, operating a primary engine at a first primary-engine power level, reducing (304) the primary-engine power level to less than the first primary-engine power level, and maintaining (306) a sum of the primary-engine power level and the SPU power level at a power level substantially equal to the SPU contingency power rating.
