  • Patent number: 4441676
    Abstract: A force control member assembly 1 comprises a force control member unit 2 carried by an intermediate member 3, the intermediate member 3 itself being attached to a fixed bracket 4 by pivot means 5 allowing resilient movement of the intermediate member 3 with respect to the fixed bracket 4 about pitch and roll axes as shown at 6. The force control member unit 2 includes a force control member and force transducer means associated therewith to generate force control signals related to control forces applied to the force control member. In use, when a control force is applied to the control member, a force control signal will be generated simultaneously with a significant displacement of the intermediate member with respect to the fixed member. The intermediate member will return to a median position on removal of a control force; this imparts a `feel` characteristic to the assembly.

  • Patent number: 4200253
    Abstract: A drooping leading edge device is provided in which the leading edge structure that droops is pivotally mounted, by a single pivot inside the wing, upon the front spar structure of the wing and is of substantially constant shape. A gap which would otherwise open up between the upper skin of the main part of the wing and the upper skin of the leading edge structure, when the leading edge droops, is filled by an upper flexible skin section secured to the main part of the wing and extending forward first into contiguity with the rear edge of the upper skin of the leading edge structure and then inside said leading edge structure. At the underneath of the wing, a rear flexible portion of the lower skin of the leading edge device extends back to meet the forward edge of the lower skin of the main part of the wing.
