User's Manual for Steady State and Transient Thermal Analysis of a Shaft-Bearing System (SHABERTH)

Abstract

Predicting the performance of helicopter engine and transmission bearings following loss of normal circulating lubrication is an important part of an aircraft vulnerability estimate. The program SHABERTH was developed to provide the means of estimating the mechanical and thermal state of critical components within a shaft-bearing-housing drive system, first in the normal service (steady state) lubricated condition, and second, in the oil-starved (transient) condition. The program is installed on the BRL Univac 1108 system and is used primarily to predict time-to-failure and failure mode after oil starvation; however, it will at the same time predict thermal dams, critical clearances and other significant behavioral features of the system under treatment, for both normal and dry operation. The program is being used for problems concerning domestic developmental aircraft and non-domestic aircraft, for which no physical test data or hardware are available.
