    With the first ever production of synthesized "solar" jet fuel, the EU-funded SOLAR-JET project has successfully demonstrated the entire production chain for renewable kerosene obtained directly from sunlight, water and carbon dioxide (CO2), therein potentially revolutionizing the future of aviation. This process has also the potential to produce any other type of fuel for transport applications, such as diesel, gasoline or pure hydrogen in a more sustainable way.

  • Among the concepts to be studied by the Astrium team are a two-stage configuration with a Vulcain II-type or expander cycle cryogenic main-stage engine, a two-stage design with a methane/oxygen main-stage engine; and a three-stage configuration with solid propulsion first- and second-stage motors.

    doesn't look very ambitious with such choices!

  • They both believe the systems engineering processes that have served the aerospace and defense community since pre-Apollo days are no longer adequate for the large and complex systems ­industry is now developing.

    1) it has to actively work and produce a result that's what you intended 2) the design must be robust. 3) it should be efficient 4) it should minimize unintended consequences. "But we have to establish a formal, mathematically precise mechanism to measure complexity and adaptability . . . [where] adaptability means the system elements have sufficient margin, and can serve multiple purposes." "We need to break the paradigm of long cycles from design to product" some interesting questions....

    indeed ... already hotly debated in CDF ... any suggestions in addition to what we already contributed to this (e.g. system level optimisation)
  • Joris _ on 03 Nov 10
     
    what is the outcome of the CDF study ? I think actually that optimisation is not at all the key point. As it is stressed in this news, it is robustness (points 2 and 4). This is something we should think about ...

  • Sanswire-TAO’s ultimate goal is to loft an airship that can ascend to the lower stratosphere, about 18 kilometers up, and fly for weeks or even months at a time, says Dan Erdberg, vice president of operations for Sanswire.
