Abstract
A biomechanical feedback arrangement wherein a varying force tending to improve the neuromotor tracking response of a human subject, particularly in the presence of lateral or front-back G force fields, is added to the test subject input member of a feedback control system. Use of the biomechanical feedback in a high-performance aircraft and in a ground-based simulator apparatus is also disclosed, along with comparison results from simulator testing of human subjects.
Claims10
Aircraft lateral tracking improvement apparatus comprising:
- aircraft maneuvering controls located adjacent a pilot supporting seat in an aircraft cockpit apparatus;
- means for conveying a prescribed lateral course to be tracked and a tracking error signal to said pilot;
- means for generating a signal representing the incurred G force acceleration of said aircraft along an axis lateral of said pilot;
- means including predetermined twelve to fifteen Hertz frequency agonistic to antagonistic muscle transfer tremor attenuation means for generating a maneuvering control bias electrical signal in response to said lateral G force acceleration signal;
- and
- bias force transducer means connected with said maneuvering controls and responsive to said bias electrical signal for applying a muscle tremor attenuation lateral bias force supplementary to one of said agonistic and antagonistic muscle forces to said maneuvering controls.
