The invention discloses a method for quickly verifying the capability of an auxiliary power device based on a rack, and the operation environment of the method comprises the steps: carrying out a
simulation test on the rack, and simulating an inlet
throat of an air
turbine starter through a contraction
nozzle in the test; before a test, a total pressure
recovery coefficient sigma and a conversion inlet area At * of an air
turbine starter are calculated, the minimum
throat area At'of the shrinkage
nozzle is determined, during the test, a test total pressure
recovery coefficient sigma'and a conversion area At * 'of the shrinkage
nozzle are calculated, and the minimum
throat area At'of the shrinkage nozzle is determined by adjusting the test total pressure
recovery coefficient sigma' or the minimum area At 'of the shrinkage nozzle. Enabling At * to be equal to At * ', obtaining the required power Pt of the auxiliary power device at the moment, calculating the
test power Pt' of the auxiliary power device at the moment, and judging whether the capability of the auxiliary power device meets the requirement or not by comparing Pt with Pt '. Through the method, the
verification method and difficulty are simplified, the capability of the auxiliary power device can be rapidly verified under the rack condition, and the
verification efficiency is effectively improved.
