the SOLUTION for the Ares-1 and 5-segments SRB dangerous "vibrations" ALREADY EXISTS I've suggested the solution of all Ares-1 problems TEN MONTHS AGO in my "Ares-F" article: http://www.gaetanomarano.it/articles/024aresF.html the SRB-5 vibrations problems (that's unexisting in the 4-segments SRB) comes from it's lenght and the fact that it's a SINGLE motor well, my Ares-1 design uses three (shorter, smaller and cheaper) Ariane-5 EAPs, then, it could have LESS "vibrations" problems of the 4- segments SRBs!!! also, this solution adds many advantages, since the three EAPs... 1. they have the SAME burning time of the SRBs 2. thay give MORE thrust of the (theoric) 5-segments SRB 3. they are READY AVAILABLE NOW while, the 5-segments SRB (IF works) will be available in 2011 4. the three EAP are cheap like an expendable 4-segments SRB ($45M) since each EAP costs only $15M while the 5-segments SRBs will be VERY HIGH PRICED: http://www.ghostnasa.com/posts/018srb5nonsense.html a further suggestion in my article is to use the (J-2X similar) Vulcain 2 tha's READY AVAILABLE NOW and only need to be man-rated and air-started (while the J-2X will be ready to fly after 2012) about the "political" problem of the Ares-F hardware... just buy the EAP and Vulcain 2 license and do make them in USA by ATK and Pratt & Whitney Rocketdyne this is the only viable solution to save time and money and have the Ares-F ready to fly within 3-4 years (then, just in time to launch the Orion, that will be ready to fly in 2012) and, don't forget, that my Ares-F will replace a rocket (the current design Ares-1) that ("vibrations or not vibrations") can't fly: http://www.ghostnasa.com/posts/012arescantfly.html .. |
