    Well it also covers all of the sub-systems on the aircraft as well, from countermeasures to communications down to how to evacuate the aircraft toilet waste. The information in tha…

    Seems novel in that they are combining the best of current rotary atomizers and electrostatic guns, and removing the need for compressed air. If you look at current electrostatic g…

    In terms of a general statement, its a bit misleading to state that sintered metal gears retain the improved strength of traditional metal gears. They are a lot stronger than plast…
