Mar. 8th, 2010 @ 09:25 am Wanted: jet engine
Hey aero engineers:

Does anyone here know how much a busted turbojet or turbofan engine would cost (the bigger the better)? I intend to use it (the fan blades, specifically) for art, not for anything dangerous. Alternatively, how much would some big fan blades cost? And who on earth do I talk to to get them? Any leads would be appreciated.

Thanks!

Jan. 28th, 2010 @ 06:34 pm searching for references in numerical methods...
Hi,

I am searching for some bibliography on the non-linear solvers used in commercial FEM software, e.g. the Sparse Direct Solver for ANSYS and so on..

Can anyone give me a piece of advice?
Welcoming any help ;)

Thanks in advance.

Dec. 8th, 2009 @ 09:11 pm On the research of the Antarctic.
airshipScientific researches in Antarctica linked to enormous difficulties not only because of the harsh climatic conditions on the mainland of the continent, but also because of the high cost of preparations for the expeditions. In turn, the high expedition’s costs depend on the inaccessibility of the Antarctic for the marine vessels and aircrafts. As a rule, only icebreakers can go to the Antarctic latitudes. The air traffic is even more difficult because of the extreme hardship building of landing strips on the ice-covered continent.


In this small article we would like to suggest some non-trivial approaches to solve traffic problems in Antarctica.

Jul. 29th, 2009 @ 12:18 am Zometool structural analysis
Attendees of the Bridges 2009 Math & Art conference are in the process of building the largest Zometool sculpture ever. It will be ~12 feet high and wide if completed, and consume 24000 parts IIRC. There isn't a master digital model yet, but the portion of the model that I do have was run through a simple structural analysis program of mine and shows significant tensional stresses at the narrow junctions.



Red is for segments in tension, blue is for compression. Since the magnitudes of the peak tension and compression forces are roughly equivalent, I have to conclude that if the structure does break, it will be a tensional pull-out failure, and will occur on the undersides of the narrow junction regions.

(cross-posted to my own journal, apologies to those who have to see it twice)

Jun. 19th, 2009 @ 04:44 pm SuperJet-100 At Le Bourget Air Show
Russia’s Sukhoi Super-Jet-100 passenger plane was presented at the air show in Le Bourget. Sukhoil Director-General Mikhail Pogosyan said that the number of orders for the plane might grow to 150 by the end of the year.

He also said that the flight testing of the plane would be completed by the end of the year, and the first four planes would be handed over to the customers – Armenia’s Armavia airline and Russia’s Aeroflot.



The SuperJet is the first new Russian passenger plane over the past 20 years. Sukhoi SuperJet-100 integrates the world's best industry practices and solutions. Its technical and operational performance make the product fully marketable and capable of taking a solid share in the highly competitive global market.
