Coordinate transformer for transforming control signals in airplanes

Claim 1

In a coordinate transformer for transforming conTrol signals for aircraft, particularly for transforming Cartesian input signals into polar output signals which aircraft have, in addition to a thrust control element, a thrust direction control element for controlling thrust components and uncoupling control axles, the improvement which comprises first and second multi-sectional linkage means connecting a control means adapted to be actuated by a pilot and a source of thrust, one of which linkage means determines the distance r, and the other of which determines the coordinated angle Alpha towards the polar axis from the two Cartesian x-y input signals, said first linkage means including a y-input signal member connected to a first rocker arm mounted in a suspended manner on a frame, coupling means connecting the end of the first rocker arm with a second counter rocker arm, first double lever means mounted on the counter rocker arm, x-input signal means acting at one end of the double lever means through an angle lever means and a coupling means, means connected at the other end of the double lever means for measuring the angle with respect to the polar axis as an output member, and said second linkage means including a third rocker arm mounted on a shaft supporting said first rocker arm, the said rocker arms being mounted normal to each other, second double lever means hingedly connected at one end through a coupling means to the end of the third rocker arm, and the other end of said second double lever means being connected through a coupling means to a fourth rocker arm on a shaft supporting the angle lever means through which the x-input signal means acts, said second double lever means being supported in the center thereof by bearing means on a fifth rocker arm which is approximately parallel to the second double lever means, angle lever means acting through an excess pressure member at the bearing means, and linkage means connected to said angle lever means, the setting value of the output movement of the latter linkage means corresponding to the distance r.
