100 rpm for all hpt submodels.

VERSION 2.64 9/30/00
Per PWC requests. Changed fixed y-scale limit
for hpt survey plots from 1.0 to 0.5 ips. Fixed bandwidth for hpt
survey to 10000 rpm instead of 9996 (coding error, numeric truncation).

VERSION 2.63 6/28/00
Per PWC requests. Added specific class weight
table for PW206B fan. Changed number of allowed weights and
acceptance limit for PW306B hpt.

VERSION 2.62 2/29/00

VERSION 2.55

Added 308 Turbine to Test Cell Version

VERSION 2.54

Unknown

VERSION 2.53 3/04/99

Predict solution from current vibration rather than starting vibrations. Changed 328Jet sensor to 2.779 Volts / Ips. Changed PW308 washer weight table to permit double washers. Added logic to select washer or saddle weights on PW308. Added weight table and hole layouts for PW308 weight table. Updated Influence Coefficients for PW306 and PW308.

VERSION 2.52 2/18/99

Added default ICF for 300 series turbines. Updated turbine weight table for 306A/B turbine. Minor modifications to 305A/B turbine weight table. Defined good turbine vibration as 0.15.

VERSION 2.51 1/22/99

Fixed bug in optimizer. Added ICF for PW306. Fixed Bug in weight table for 306A. Added logic to vary weight based on hole position to compensate for weight of rivets.
