Indirect drive active control column

摘要

An indirect drive active control column for an aircraft control system is provided. The indirect drive active control column provides both active and passive feedback to the control stick. The passive feedback relates to adjustments of the control stick relative to a feedback neutral position. The active feedback actively adjusts the position of the feedback neutral position to adjust a feedback profile of the passive feedback.

主权项

1. An indirect drive active control column comprising:
a stick moveable relative to a mechanical ground; a passive feedback arrangement movable relative to the mechanical ground, the passive feedback arrangement directly acting on the stick providing a passive feedback force profile to the stick when the stick is moved relative to the passive feedback arrangement; an actuator coupled to the passive feedback arrangement for actively adjusting the position of the passive feedback arrangement relative to the mechanical ground; and wherein the passive feedback assembly includes a cam including a cam surface and a resistance arrangement, the cam surface defining a feedback neutral position, the stick includes a cam follower following the cam surface, wherein the resistance arrangement increasingly biases the cam surface to resists movement of the cam follower from the feedback neutral position to provide the passive tactile feedback.
