Homework Help: Rewriting aircraft equations of motion

  1. Apr 6, 2009 #1
    Hi, I hope someone can help me with this question, although its aeronautical engineering, I think I have more of a maths related problem - I don't really know where to start.

    I have been a given a matrix containing aircraft equations of motion (see attached picture). Also shown is an equation involving the pilot rudder input (where r is the yawing angular velocity).

    Please note: when i looked at the attachment on my computer, the smaller equation didn't display properly until i zoomed in a bit - a minus sign seemed to be missing.

    I am asked to rewrite the equation (by 'equation' I think they mean the matrix of equations) showing the pilot’s input only on the right hand side.

    I won't attempt to write out all the symbols etc, but my guess at the solution would be to change the top row of the left hand side adding to each column the term -ζ+kr. Though I wouldn't really know what to do about the right hand side - (would the left hand column of the first matrix be deleted - if so that would surely have to change the left hand side of the expression).

    Any help with this problem would be much appreciated.
