Goals of the 1st Smolensk Conference Create space for exchange of scientific results on 10.04.2010 Create data basis for those who want to perform such research Limiting factors No posibility of examining the wreckage and „black boxes” No access to reliable data Part of evidence irreversibly lost due to improper treatment No funding of such research is available in Poland Positive elements In scientific community growing awareness of loopholes of the official investigation Growing number of scientists who openly declare their will of undertaking the examination

Examples of the difficulties we have...

17 m ? Radar altitude 120° Inconsistencies of the official reports (need access to original data) 17 m ? Radar altitude 120°

Issues that require laboratory examination (first of all, bring the wreckage to our labs)

Data source files are needed and not low-quality plots of the official reports Example: possible problem with engine 3 (not mentioned in the official reports)

The twin aircraft 102 is an important source of knowledge on technical details. Experience with servicing in Poland of former Soviet aircrafts shows that details of construction typically differ from the published technical documentation. Polish authorities try to sell 102 to Russia, which expresses interest in this transaction...

Funding? Standard paths of funding grants are here unavailable – the project is sensu stricto neither fundamental nor applied

Project proposal for National Center for Research & Development (NCBiR) Parametric modeling of the final few seconds of flight of TU-154M in Smolensk on 10 April 2010 Gdańsk University of Technology (Politechnika Gdańska) 5 departments from 4 faculties Institute of Fluid-Flow Machinery, Polish Academy of Sciences (IMP PAN) 3 departments 15 permanent group members + up to 20 persons to hire Duration 2 years

Examples of previous activities of the Gdańsk group
