A Comprehensive Study on Design Standards for Ground Testing of Helicopter Transmission System

Transmission system is one of the most important and critical parts of a helicopter. Stringent test requirements are therefore essential to prove capability of the system and thereby ensuring flight safety of helicopter. With this objective, different standards have been defined by military and civil certification agencies. In this paper major system level ground test requirements prescribed in some of the widely accepted standards have been examined and compared. Similarity in test requirements is observed in many cases with a few significant differences.
