Using of Damper Supports (DS) is the most effective way to decrease vibration level and dynamical stresses in engine parts. A rather difficult problem of DS design can be separated into three main stages as the following:

1. Denision to use a DS: DS locating, definition of desired stiffness and damping.
2. DS design: choice of the DS type, calculation of its main dimensions, detailed design.
3. DS manufacturing and testing, including engine tests.

Purpose of this Guide is to disclose the milestone points, DS layouts and design, to disclose current possibilities in DS design.
