The main objective of the Integrity Improvement of Rotorcraft Main Gear Box (MGB) research project has been to determine ways of improving the integrity of rotorcraft gearboxes. There have been two primary work streams to be carried out as part of this research project:

Stream 1: The project should evaluate rotor and rotor drive system configurations and determine system architecture and design means to prevent single points of catastrophic failure, wherever possible. This can be accomplished by means of a review of typical rotorcraft gearbox configurations and development of proposals for improvements based on the knowledge and experience of the organisation conducting the research.

Stream 2: The project should identify the most significant design parameters that influence the reliability and tolerance to flaws of case-hardened materials subject to rolling contact fatigue. Based on the outcome of this activity, rolling contact fatigue tests and simulations should be conducted with the objective to:

After a public tender procedure, EASA awarded the project implementation to Airbus Helicopters Technik (former ZF Luftfahrttechnik GmbH). The project team has now successfully accomplished all tasks and would like to invite you for the final dissemination webinar.

In this webinar, EASA and the project team of Airbus Helicopters Technik will:
