Loads and damage tolerance for helicopters

This report reviews the applicability of damage tolerance concepts to helicopter structures. After a general discussion of the damage tolerance concept, attention is paid to the specific aspects of the helicopter loading environment. Examples are presented of damage tolerant design, both in metal and in composite structures. However, it is felt...

Investigation of a cross-coupling drift compensation method on a single axis gyro stabilized platform

In this report the phenomenon of cross-coupling drift (both S-IA and S-OA) due to vehicular angular movements is investigated. In a hardware test set-up, using an experimental Single Axis Platform composed of surplus parts from the former Eldo-A program, the theoretical result as well as a proposed method of compensation is verified.
