Feanor paper at Airtec 2001 Conference - Frankfurt 2-4 November 2011

6th International Conference “Supply on the wings” 

The International „Conference Supply on the wings“ takes place for the sixth time, November 2 - 4, 2011 in conjunction with AIRTEC. Chairman of the conference is also this year Professor Dr Ing. Richard Degenhardt, Private University of Applied Sciences PFH), Göttingen and German Aerospace Center (DLR). 

This year the future-oriented specialised conference for the aerospace supply chain is under the title "Aerospace - The global innovation driven" and will be again an optimal combination of lectures from industry and science and thus connecting practice and science in a perfect way. It offers excellent opportunities to exchange intensively knowledge, experience and information and to network with renowned experts from industry, governmental institutions, research centres, scientific institutions and universities from the international aerospace sector.

Feanor contribution refers to NDT technology for frame structures with X-Ray diffraction. The purpose of shot peening (blasting) process is the induction of residual compression stress on the surface of components subject to fatigue loads. This is obtained impacting a surface with shots (round metallic, glass, or ceramic particles) with a force sufficient to create plastic deformation. It is similar to sandblasting, except that it operates by the mechanism of plasticity rather than abrasion. This process has been used for many years on special steel automotive (shift gears, connecting rods and suspension components) and aerospace components, in Titanium alloys and light alloy steel.

The characterization of the shot peening process is defined by specific parameters, according to legislation, such as the intensity (expressed in Almen), the diameter of the particles and the degree of coverage. When used on components made of a material different from the Almen specimen (steel), the stress field in the component structure cannot be easily estimated. In that particular case we rely on bibliography for the definition of the process parameters. By use of X-ray diffraction with a new type of instrument, the authors were able to measure the real tensile stress induced by shot peening, carried out with two different parameters on aeronautical structural components in Aluminum alloys.

International Metrology Day 20 May 2011

International Metrology Day 20 May 2011. Feanor OÜ awarded in in Metrology Forum (Moskow VVC) for ‘Research and Development on Software for Calibration and Metrology’

Today 20 May 2011 is the International Metrology Day and there was no better way to celebrate it than by receiving an official recognition by the Federal Agency of Technology and Metrology of the Ministry of Production of the Russian Federation.

The award acknowledges Feanor OU for ‘Research and Development on Software for Calibration and Metrology’ and was presented to Feanor CEO Luca Giorgio Bochese by the Ministry of Production of the Russian Federation, during the International Metrology  Symposium held in Moskow VVC from 16 to 19 May.

There are a number of projects we are involved in at the moment, including measurement of special gears (elliptical), improvement of calibration for large machine tools and CMM (coordinate measuring machines), NDT (non-destructive) inspection equipment for applications in chemical equipment, nuclear facilities, shipbuilding (high pressures) and aerospace (extremely low pressures). This award is the second recognition, after VTTV Omsk in 2009, we ever received in Russia, and confirms that our research and our products have a good chance to contribute to the modernization and continuous improvement of the metrological and technical infrastructure in high precision local manufacturing companies. 

The forum was a success, particularly because of the high level contacts we have generated and fostered with Stankin Institute, Rostest, ROSATOM SNIIP, RUSNANO (Nanotechnology), VNIIM (Metrology Institute) and a number of Technical Universities and Metrology Institutes in different countries and regions, including Kazakhstan, Kazan, Ukraine, Tomsk, Novosibirsk. 

Innovation in Measurement of Residual Stress

Feanor recently developed a portable and compact X-ray diffractometer for XRD, which allows residual stress measurement on-the-field.

XRD (X-Ray Diffraction) technique for residual stress measurement is a technique still known and used in university laboratories.

A particular application on inspection of a welding on a petrochemical reactor will be the subject of a scientific paper, being presented at 7th International Symposium on Precision Engineering Measurements and Instrumentation ( ISPEMI2011), held by the School of Instrument Science and Opto-electronic Engineering of Hefei University of Technology, China http://ispemi.hfut.edu.cn

Fig.1: Diffractometer

The device measures X-ray diffraction generated by electrons inside the anticathode atoms when hit by a flow of high speed electrons, identifying peaks of intensity related to wavelengths related to the anticathode atoms. As an example, if a chrome anticathode is hit with a band of electrons, having energy above the threshold value, it will emit characteristic X rays with a wavelength of about 0.229 nm. A cobalt anticathode will emit a characteristic radiation with a wavelength of about 0.179 nm. When the material irradiated is crystalline, as in the case of metals, the waves diffused will interfere with each other giving a diffraction spectrum.

These re-emitted wave fields interfere with each other either constructively or destructively (overlapping waves either add together to produce stronger peaks or subtract from each other to some degree), producing a diffraction pattern on a detector. The resulting wave interference pattern is the basis of diffraction analysis, called 'Bragg diffraction', and using the related Bragg's Law we are able to relate this information to the tensile stress field of the crystalline structure of the inspected material.

Fig.2: Bragg’s interference

The picture shows the evaluation of inside tensile stress on a welded joint, on a petrochemical reactor, to inspect and verify the effect of the heat treatment. After heat treatment, the surfaces had been sand blasted before painting. The sand blasting process modified and induced a residual stress on the surface, different from the inside. For this reason it was necessary to remove the modified layer using an electrochemical etching, in order to inspect the stress field at different layers without inducing any modification. 

Fig. 3: Testing the petrochemical reactor surface near the welding joint

The paper shows how X-Ray diffraction can be used as non destructive technology to evaluate the impact of stress relief after heat treatment on large surfaces, when not feasible or possible to extract a sample for testing. Well, strictly speaking and according to picture 4, it cannot be considered as 100% non destructive, but its impact is anyway much less invasive, compared to other traditional systems (hole drilling).

This new equipment will also participate in the competition within the 7th Moskow  International Forum and Metrology Symposium (MetrolExpo) in May 2011, under the category 'Quality Mark for diagnostics and non-destructive equipment' http://www.metrol.expoprom.ru/en/

Investments in new manufacturing equipment slowing down

The 12.800 square meters manufacturing plant in Xian Technology Park is almost ready, but investments in equipment will be slowed down, according to the reduced export share forecasts outside China, Korea and India.
Feanor traditional Automotive, Aerospace and Defense markets in South East are not so bad as in the West, and focus will be there in the next two years.
Feanor got no support for research in Estonia in the last twelve years, nor for participation to exhibitions to improve export turnover, that's why design, prototyping and manufacturing of new sensors will be relocated in Xian plant.
Future patents will be registered in China and 10-15 technical staff will be initially provided by Xian Technology Institute. Optimal size would be 300 units.
Other reasons for relocating is lack of local industrial customers (export for many products has constantly been 100%) and skilled personnel.
'Chinese are clever, active and motivated, and this is what is most needed for hi-tech research'.
Translation services, representing more than 10% of total activities, will continue to operate in Estonia.
