Research for the Finnish Air Force by VTT extended the life of high-pressure turbine blades in Hornets -- almost hundredfold savings achieved

Research for the Finnish Air Force by VTT extended the life of high-pressure turbine blades in Hornets - almost hundredfold saving achieved

With the help of research by VTT Technical Research Centre of Finland, the Finnish Air Force (FINAF) has succeeded in increasing the operational life of the high pressure turbine (HPT) blades of its Hornet jet engines by 10%. The saving for taxpayers is an estimated 3 million US dollars, or over 2.7 million euros, compared to which the research investment was modest and the return (ROI) almost 100 times the research investment.

FINAF sent the VTT's research results and some used HPT blades to the engine manufacturer. On the basis of the research findings and its operational experience, GE increased the lifespan of the HPT blades for its F/A-18C/D Hornet engines (2 × General Electric F404-GE-402) by around 10%. The FINAF has adopted the new life limit into operational use since May 2015.

VTT's research for FINAF has therefore created savings for the taxpayer and will ensure expertise-based security of supply in Finland.

#537 Science Journalism, Hold the Hype
Everyone's seen a piece of science getting over-exaggerated in the media. Most people would be quick to blame journalists and big media for getting in wrong. In many cases, you'd be right. But there's other sources of hype in science journalism. and one of them can be found in the humble, and little-known press release. We're talking with Chris Chambers about doing science about science journalism, and where the hype creeps in.
