Model Based Improvement of Performance, Maintainability and Reliabi lity of Helicopter Structures


Foreseen Results

A set of procedures and refined techniques for the optimal execution of
ground and flight tests of helicopter for vibration purposes
the corresponding data analysis
the generation of the finite element model
the correlation and updating of the various data sets

A guideline to use the obtained data to the improvement of performance, reliability and maintainability of the helicopter.

The demonstration of the investigated approach for a few selected design problems.
The main aim of the project is to realize a consistent approach to the model supported design of complex structures. The methodology will be developed and validated around the industrial case of a helicopter structure, but its applicability will be general. This "virtual prototyping" approach should form the basis for model simulation as well as design of proper modifications of the structure, improving performance and reliability and safety. Ultimately, it should enable the development of a model-based predictive maintainability strategy.

The main activities of the project will focus on the modelling of complex structures in real operating conditions, particularly on improving the numerical CAE (FEM) model based on ground and flight test data modelling.

This will start from a comprehensive evaluation of the state-of-the-art in this field involving the selection and validation of the most appropriate techniques, the transfer of the required know-how on modelling and model improvement to the Polish partners, and the joint execution of the testing and numerical modelling work.

The result of the project will be a documented procedure for the application of model based virtual prototyping of complex structures, validated for the case of helicopter design. It will include the required refined methodologies for in-flight testing, as well as for modelling and model updating from in-flight data.

The consortium formed to reach these goals consists of a Polish helicopter manufacturer, a leading Polish and UK university and a Belgian engineering company specialized in structural dynamics methods.

The proposal directly relates to Theme 7.3 of the INCO-Copernicus work programme: "Design of products and processes, involving tools and techniques for innovative design, maintainability and reliability".
