STATIC AND ROTORDYNAMIC CHARACTERISTICS FOR A NEW HOLE-PATTERN ANNULAR GAS SEAL DESIGN INCORPORATING LARGER DIAMETER HOLES Conference Paper uri icon

abstract

  • To reduce manufacturing cost and time, a new larger-diameter hole-pattern seal incorporating hole diameters of 12.27 mm, versus prior hole diameters of 3.175 mm has been proposed. The 12.27 mm hole-diameter seal had substantially better stability performance with higher effective damping and a markedly lower cross-over frequency. It had negative direct stiffness coefficients at low frequency, while the 3.175 mm hole-diameter seal did not.
