A Rapid Method to Achieve Aero-Engine Blade Form Detection

This paper proposes a rapid method to detect aero-engine blade form, according to the characteristics of an aero-engine blade surface. This method first deduces an inclination error model in free-form surface measurements based on the non-contact laser triangulation principle. Then a four-coordinate measuring system was independently developed, a special fixture was designed according to the bl...

Robotic Assembly of Aero - Engine Components

The VITAL (EnVIronmenTALly Friendly Aero Engines) project funded by the European Commission under its Framework 6 Programme aims to provide significant reductions in fuel burn, emissions and noise through the development of innovative design and manufacturing techniques. One way to reduce the amount of fuel burnt, and hence CO2 produced, is to reduce the weight of the engine. A significant prop...

Aero-Engine Adaptive Fuzzy Decoupling Control

A new kind of multivariable adaptive fuzzy decoupling controller is present for Aero-engine, which consists of multivariable fuzzy decoupling control and fuzzy model reference learning control. A fuzzy inverse model is used to produce and adjust fuzzy rules online. The simulation results show that this controller is effective.

A Variable-Fidelity Modeling Method for Aero-Loads Prediction

A Variable-Fidelity Modeling (VFM) method has been developed as an efficient and accurate aerodynamic data modeling strategy. In this approach, a set of CFD methods with varying degrees of fidelity and computational expense is exercised to reduce the number of expensive high-fidelity computations. Kriging-based bridge functions are constructed to match the lowand high fidelity CFD data. The met...
