Elaboration of the Method for Quick Estimation of Aeroelastic Characteristics during In-Flight Flutter Tests
Virtual Engineering Group of Poznan University of Technology entered a new cooperation with Institute of Aviation, Warsaw.
The project:
“Elaboration of the Method for Quick Estimation of Aeroelastic Characteristics during In-Flight Flutter Tests“
is being carried out under the Operational Program Innovative Economy 2007-2013, Priority 1 „Research and Development of New Technologies“, Activity 1.3 “Support for R&D projects for enterprises undertaken by science establishments“, Sub-Activity 1.3.1 “Development Projects“
The main aim of the project is to meet the following functional requirements for flutterometer set by plane producers and test pilots:
- 20+ measurements at a sampling rate of 32+ Hz
- Completely automatic identification of mode frequencies and damping ratios
- One global result for all measurements
- Period of the update of the identified modes: max.1 second
- Mode frequency range: from 0.5 Hz
In the computational part of the project the following aspects are to be taken into account:
- Numerical analysis of the plane aeroelasticity based on a dynamically similar model designed for tests a in wind tunnel
- Building a numerical solid-structural model of the plane based on a dynamically similar model
- Validating the numerical model of the plane
In the framework of the project, the only one in Poland FLUTTER LABORATORY has been established:
