Using Shuttle SRB technology
With the demise of the shuttle program, there may be a large capacity
to make shuttle SRB going to waste. Why not make non-re-usable SRB for commercial purposes? Non-re-usable would greatly reduce the cost. |

I doubt it would save much Reusing today costs about the same as new every time. Considering costs of recovery etc If non reusable had great saving NASA would of proposed it as a shuttle upgrade |

Non-re-usable would greatly reduce the cost. Ask yourself, if it's such a great idea, why hasn't anyone done it before? -- Greg Moore Ask me about lily, an RPI based CMC. |

I did some reading up on that after my posting. The field joints on the filament-wound booster became the basis of the design used on the current SRBs when they were redesigned after Challenger was lost. Pat |

Yes, from dim memory: The ASRM program used a different supplier for the composite wound casings. I'm not certain how far the rogram actually got before it was cancelled. The casings promised to be lighter, and would therefore increase the payload capacity of the shuttle stack, particularly to high inclination orbits (e.g. polar orbits launched from Vandenburg). With the demise of Vandenburg as a launch site, the motivation for the project quickly evaporated. From the web: http://www.globalsecurity.org/space/...s/sts-asrm.htm http://www.astronautix.com/stages/shueasrm.htm The NASA technical documents server has at least 7 papers on the ASRM: http://ntrs.nasa.gov/search.jsp?Ns=HarvestDate|1&N=4294888953+280&Ntk=a ll&Ntx=mode%20matchall&Ntt=asrm There are a total of 7 record(s) matching your query.

With the demise of Vandenburg as a launch site, the motivation for the project quickly evaporated. I think you're confusing Filament-wound Solid Rocket Booster with the Advanced Solid Rocket Motor. FWSRB was a composite casing version of the standard SRB intended to improve Vandenberg performance and vanished without a trace after 51L. ASRM was a later program intended to increase payload for Space Station missions using a slightly greater diameter steel casing made up of three segments (one fewer field joint.) Brian |
