Abstract：In the first trial-manufacture of an aero-engine centrifugal fuel nozzle, the spray angle is smaller than design
requirements, through theoretical analysis, formulate measures for a variety of commissioning process, and has carried
out experimental study. Tests show that measures for reducing swirl angle, reducing spout length, increasing spout diameter,
reducing swirl chamber length and reducing swirl tank depth can increase the spray angle to a certain extent. Eventually,
we adopted double angle rubbing process, combined with the measures for decreasing the swirl tank depth, has reached the
design requirements of the spray angle.
