<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>Finite element analyses and computational fluid dynamics analyses are commonly performed throughout a development program and often afterwards to diagnose and correct issues that arise later.&nbsp; They are often performed very early, during proposal preparation before a contract is even awarded and many times after that during a development program.&nbsp; If all that you have is that sort of analysis that ought to get you to about a TRL of 3.&nbsp; You are a very long way from just an integration effort when the analysis is complete.&nbsp; </DIV></p><p>Again I will disagree,&nbsp; the LTA component is the only new piece.&nbsp; Everything else comes with an RFI tag and data attached.&nbsp;There will be some ECPs but the intent is to use Off-the-shelf with minimum modifications.</p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>There is a lot of testing needed to validate the analysis and more analysis as pieces come together and more testing and more analysis and</DIV></p><p>Much of which can be done on a computer in a simulated environment.&nbsp;</p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>&nbsp;...

Each test will reqjuire a fnite element analysis and comparison with test data from a large number of strain gauges. Then you need to address the structure to be built of those pieces. You will probably need to perform some sort of modal testing to support the dynamics analysis, and you will likely need quite a bit of destructive testing to validate the structural analysis.&nbsp; And this is only a quick overview of what will probably be a lot more involved analysis and testing. just for the composite framwork.&nbsp; <br />Posted by DrRocket</DIV><br /><br />I invite you to go count the number of pieces in the design.</p> <div class="Discussion_UserSignature"> <p> </p><p>"I am therefore I think" </p><p>"The only thing "I HAVE TO DO!!" is die, in everything else I have freewill" Brian P.

Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>$100k for this sort of program won't last an hour.Let me give you a yardstick, though perhaps a poor one.&nbsp; A while back I was working on a proposal for moving the manufacture of a rocket motor from one location to another.&nbsp; The design existed.&nbsp; All we had to do was to figure out how to manufacture it in another location, using somewhat different equipment,&nbsp;without changing it too much.&nbsp; We spent about&nbsp;2 months putting that proposal together and were spending well in excess of $20,000 per day.&nbsp; That was just in trying to figure out how to do the job and what it would cost.&nbsp; We didn't actually make anything during that period.&nbsp; This work was quite a bit less complex and less risky than development of a system with an entirely new approach. <br />Posted by DrRocket</DIV><br /><br />Well then I guess getting an entirely new system through what I would call the concept refinement phase of the acquisition life cycle and ready to begin the development phase for $100K represents quite a bargain and justifies NASAs faith in the COTS process. <div class="Discussion_UserSignature"> <p> </p><p>"I am therefore I think" </p><p>"The only thing "I HAVE TO DO!!" is die, in everything else I have freewill" Brian P.
