Engine Mount System for Ultra High Pass Engine

Periodic Reporting for period 5 - EMS UHPE (Engine Mount System for Ultra High Pass Engine)

Reporting period: 2019-11-15 to 2020-08-14

The objectives of this applicant consortium to the project for the Engine Mounts System (EMS) of the Ultra-High Propulsive Efficiency (UHPE) are primarily two:

1. Evaluation and selection of the most promising and suitable Technologies for implementation on Engine Mounts System (EMS), to provide a significant leap in the performance (mainly weight and dynamic behaviour), manufacturing, and assembly of the EMS. This evaluation will be completed using LORD broad experience in EMS configurations and concepts and modelling and analysis of configurations thru virtual prototyping (dynamic modelling) where Politecnico di Milano, Vicoter and LORD have expertise and capability.

2. Develop, design, build and test, in this project, the selected technologies and EMS solutions to significantly advance Technology Readiness Level (TRL).
LORD is collaborating on two main axis which are the Concept Studies and EMS Specification and the second which is Innovation and New Technology Development.

During this first period, the consortium led by LORD has been working on Management and Reporting and EMS for Ground Test (GT) Design and Development as well as identifying preliminary instrumentation needs related to Support activities for the Engine GT. The Management and reporting activities have mainly been impacted by several schedule changes communicated by SAFRAN Aircraft Engine (SAE) and the consequent changes to milestone, deliverables, and work packages description of the Consortium DOA.

Some preliminary activities within the GT Design and Development have been performed to support the different iterations of engine and installation configuration from the topic Manager.
During the second period, the consortium has been working on Work Package 1, Work Package 2, Work Package 3 and Work Package 7.

Within work package 1, the consortium has organized specific sessions with the Consortium to reinforce internal procedures supporting the project management and also covering the requirements for technical and financial reporting.

For work package 2, the Topic Manager delivery was on March 2018 and discussion are still ongoing to define and commonly agree on a path forward.

In work package 3 there were no actual deliverables due during the second period however following the schedule push out announced by the Topic Manager in October 2017. The consortium did nonetheless pursue some activities that have been executed to consolidate the up to date Engine Mounting System design.

Within work package 7, we have continued to investigate and work on Advanced Manufacturing Methods and technologies with the aim to reduce manufacturing lead-time, complexity and costs; looking into manufacturing processes and methods developing new solutions and technologies that are intended to address the challenges coming from the new generation turbofan engines.

During the third period, the consortium has been working on Work Package 1, Work Package 2, Work Package 3, Work Package 4 and Work Package 7. Work Package 1 activities continue to progress in line with the last amendment. Work Package 2 and Work package 7 activities have been impacted by issues related on consortium modelling needs as expressed in DOA, against the Topic Manager modelling delivery. In order to accommodate these, the consortium worked during this third period on a plan that intended to have a better overall visibility on the critical path (WP3 & 4) when the Topic Manager will kick-off again these activities, as well as, continuing to set-up partnership, create detailed statement of works and develop low TRL technologies from WP7.

During the fourth period, the consortium has been working on Work Package 1, Work Package 2 and Work Package 7. Work Package 1 activities are still mainly impacted by the last UHPE schedule communicated by the Topic Manager on June 06, 2019 that directly affects the consortium Work Package 3, 4, 5 & 6. Work Package 2 being impacted by issues related on consortium modelling needs as expressed in DOA, against the Topic Manager modelling delivery (cf Third Period report), activity on this Work Package were dedicated to support the Deliverable D2.1. Some low TRL technologies from Work package 7 being also impacted by issues related on consortium modelling needs (cf Third Period report), the consortium dedicated its effort on WP7 technologies development that aren’t dependant on specific inputs from the Topic Manager, i.e. items 7, 10, 11, 12, 13 thru 16, 20, 27 & 28.
During this fifth period, consortium main activities were focused on:
- WP1: GA Amendment (not impacted by COVID-19 situation)
- WP7: Highly impacted by COVID-19 situation.

Simulation and experimental activities are tightly integrated, thus the development of simulation tools is slowed because of the lack correlation with experimental data.

In addition, as presented in the deliverable D7.1 WP7 items are linked with each other.

As a result of the pandemic situation:
• Prioritization on activities that are not impacted by COVID19 lockdown such as modelling activities, with limitation to the fact that modelling activities needs testing input (all testing facilities being under lockdown)
• Consider in the amendment effort that was under discussion prior the pandemic, a new timeline which takes into account the expected and currently estimated 6 months delay
Within the Innovation and New Technologies Development, understanding the behaviour of the material as well as being able to predict it with good accuracy will allow to advance the state of the art of EMS design for Ultra High Bypass Ratio engines. Space envelope/design optimization will lead to new innovative type of architecture. Better motion control, A/C fuselage high load filter, weight saving, manufacturing cost reduction and easier installation are examples of what a future EMS design can achieve. All of this contributes to the ultimate engine goal of allowing for cleaner and quieter generation of engines.
The consortium will continue development of the high value technologies in support of the next generation of engine and associated EMS. The consortium will work to increase the technical readiness level and evaluate the feasibility, benefit and/or challenges for those identified technologies.
