Abstract
The article of record as published may be found at http://dx.doi.org/10.2514/3.24129Presented as Paper 93-2389 at the AIAA/SAE/ASME/ASEE 29th Joint Propulsion Conference, Monterey, CA, June 28-30, 1993Large cyclical pressure excursions from stator-averaged values are observed on the suction side of a
rotor blade at the case wall in a multistage compressor as the rotor moves relative to the stator. The
pressure changes correlate well with stator relative position, occur in the passage away from the blade,
and are only slightly modified by tip clearance changes. Close to the entry and exit of the tip gap, however,
the pressures remain stable. The pressures near the gap are only slightly affected by stator proximity
and primarily vary with tip gap height.Naval Air Systems CommandAir Breathing Propulsion Research Progra
