Project

Advanced Landing Gear Sensing & Monitoring (ALGeSMo) is a system that measures load and torque at the landing gear to provide these data for use on the aircraft systems for integration with aircraft health monitoring, hard landing and overload detection, flight management and flight controls.

The work consisted in developing and flight testing landing gear loads measurement technology in view of further functional integration in large aircraft avionics systems.

  • The project started formally in September 2016 and ended in October 2020, with a successful demonstration of the system on an iron bird test rig.
  • The project consisted of six main work packages (WP).
  • Total duration: 50 months.

Overview of Consortium and Roles

Work Package Definition and Breakdown Structure

WP1 – Project Management

  • Duration:
    50 months (M1-M50)
  • Lead:
    Meggitt UK Ltd (Airframe Systems, UK – formerly Meggitt Sensing Systems, UK)

This Work Package was set up to primarily enable the achievement of the objectives of the project with respect to time and budget. This included managing the financial and contractual obligations of the consortium, ensuring smooth progress of the work through regular monitoring and communications, ensuring the quality of the work and its deliverables, detecting and managing growing risks and issues that may hinder the work, establishing the necessary actions and plans to ensure appropriate dissemination activity, IP protection, and exploitation of results.


WP2 – Specifications

  • Duration:
    36 months (M1-M36)
  • Lead:
    Meggitt SA (Airframe Systems, Switzerland – formerly Meggitt Sensing Systems, Switzerland)

The objective of WP2 was to set the initial baseline of the sensing system. The definition of the WP2 baseline included all generic requirements, ranging from environmental constraints to safety-of-flight tests, and ensured the creation of a physical envelope that all the partners could use for the implementation of their solutions. Based on the requirements set out by Airbus at the start of the project, the project team then translated this in to a systems specification. This task was a strongly iterative and interactive process with WP3 (Design) and WP5 (Testing). While there was some fundamental requirements and specifications that could be made at the start of the project, it required a series of initial trials and evaluations to understand the behaviour of the prototype sensors to ensure they met the required performance (accuracy, resolution, etc.) before the full system architecture could be specified.


WP3 – Sensor and System Design

  • Duration:
    40 months (M3-M42)
  • Lead:
    Meggitt SA (Airframe Systems, Switzerland – formerly Meggitt Sensing Systems, Switzerland)

The objective for this WP was to design all the components required for the monitoring system. The specifications defined from WP2 provided the baseline for the equipment design. The design phase did comprise a wide range of sub-tasks dedicated to individual aspects of the load monitoring system and sub-systems. There was a lot of inter-dependency between these sub-tasks and with the WP2 (Specification) and WP5 (Testing).


WP4 – Manufacturing

  • Duration:
    46 months (M1-M46)
  • Lead:
    Meggitt Aerospace Ltd (Airframe Systems, UK – formerly Meggitt Polymers & Composites, UK)

The objective of this WP was to manufacture the mechanical, optical, and electronics parts necessary to build the complete landing gear sensing system. However, looking towards exploitation, the task also considered how manufacturing processes could be optimised to allow ramp up to full volume production and manufacture.


WP5 – Testing

  • Duration:
    50 months (M1-M50)
  • Lead:
    Royal Netherlands Aerospace Centre (NLR), NL

The main objective of this WP was to undertake component, sub-system, and system level tests to demonstrate the technology satisfies TRL5 requirements. Bespoke test rigs were required and a wide range of testing was performed.
