    Question bank - errors in questions?

    I am struggling with the following 4 questions:

    Question ID: 210732

    Is this question correct or the answer that is?

    Are the Stators followed by rotors or vise versa?

    Question ID: 210450

    Answer ?produce less maximum power output?? the explanation talks about power to weight ratio. Is the text of the answer on the same lines?

    Question ID: 220256
    Turning errors – correct answer give is ?a decrease in heading? isnt this incorrect shouldn?t the correct answer be either increase in heading or apparent turn to the south?

    Question ID: 820 209
    If an autorotative descent is commenced from a high altitude and collective position is not changed, then, as altitude reduces, rotor RPM:

    Answer given as correct: ?and rate of descent will decrease?

    Best regards,
    IH2

    In a compressor a rotor preceeds a stator, and in a turbine a stator preceeds a rotor.
    The compressor compresses the air, the turbine is after combustion, and drives the compressor.

    Thanks for your quick reply. Ill move the latter two questions to the appropriate forum.

    But how does question 210680 then fit in?

    Question:

    ?A stage in an axial compressor:?

    Anwer given as correct:

    ?Consists of a rotor disc followed by a ring of stator blades?

    Hi
    this has been posted under AGK, and only the first two question are AGK, both of which the answers and explanations are correct. In a turbine, a stator is followed by a rotor, and a gasoline engine will produce more power than the same size diesel engine.

    The other two are PoF, and will be answered by the relevant expert.

    Regards
    Keith
