DARPA Open-Sources Military Vehicle Design 105

Posted by samzenpus from the bigger-fins-and-a-hood-scoop dept.
Velcroman1 writes "The army's secretive technology division has been collecting dozens of ideas for the design of its in-the-works rescue vehicle via a social-media contest — relying solely on the power of the crowd to get the next big thing built. Local Motors of Chandler, Ariz., is running the competition, officially known as the Experimental Crowd-derived Combat-support Vehicle (XC2V) Design Challenge, through March 10. It's not so different from when multiple users edit a page on Wikipedia, Local Motors CEO John Rogers said. 'Effectively, we want to co-create all aspects of a vehicle,' Rogers explained. 'The Wikipedia method of co-creation is really not far off from the way we talk about it.'"

    And yet somehow it will still get built by the same contractors the military already uses, have huge cost overruns, weigh too much, and be unable to fully fulfill the mission for which it was originally designed. The problem with our military-industrial complex isn't in the design stage. Historically we've had brilliant designers. The issues arise in the politics involved with defense acquisitions. Our procurement and testing system is notoriously corrupt. Preference is always given to the same big companies. If a new design/weapon/technology threatens some general's(or congressman's) pet project, it is dropped. Start looking outside the usually suspects for stuff like this, not designing. Make defense contracts actually be real bid contracts, and keep them adhered to the contract.

                Reality is for a flexible vehicle the driver and passengers should be as far forward as possible. The motor should be as low as possible, preferably horizontally opposed http://en.wikipedia.org/wiki/Flat_engine [wikipedia.org], under the driver and passengers butt.

Start throwing in a bunch of contradictory requirements and you end up with tradeoffs in design which means the final product doesn't meet any of the requirements all that well.

    That puts a kind of serious limitation on just how creative you can get. If you could at least move the driver around, you could try for some interesting arrangements or variations, but if the driver has to be in the one standard spot, and the wheel position is already determined, and the frame... they are going to get an awful lot of designs which are just variations on a theme, I suspect.
