Fuel Tank Question
Question from a non-aviation engineer - how does the fuel pick up in an aerobatic aeroplane work? When it's under negative G, or sloshing about wildly during wild acrobatics, I can't see how a fixed pickup could keep up. I thought of a bladder type arrangement which could pressurise the fuel and pick up from the bladder neck, but this means the fuel would be under pressure at all times, including during filling. It also wouldn't permit any baffles in the tank, which I assume must be there to reduce the sloshing mentioned earlier. Even airliners must suffer from this to some degree, eg during take off acceleration.
Sorry if it's obvious, but enlighten me someone please?
