초록 ▼

A system for vibrating a seat within the cockpit of a flight trainer to simulate aircraft buffeting. The seat is mounted at its rear on a pair of linear bearings which permit z axis movement of the seat relative to the trainer cockpit. A hydraulic actuator, acting through a bell crank and link, vibrates the seat up and down under computer control. The computer determines the required seat vibration frequency and amplitude as a function of simulated aircraft angle of attack and maneuvering load factor. Analog signals representing the computed vibration frequency and amplitude are fed to a voltage controlled ramp generator which provides a seat driving signal to the hydraulic actuator through a closed loop servo system.

대표청구항 ▼

Apparatus for simulating, in the cockpit of a flight trainer, the buffeting experienced in an operational aircraft, comprising: an ejection rail located within the cockpit of said flight trainer; a seat mounted on said ejection rail; means fixed relative to said cockpit for supporting said ejection rail from the rear; at least one linear bearing oriented along the trainer\s z-axis and connecting said ejection rail to said rear supporting means; means for jointly vibrating said seat and ejection rail relative to said cockpit along said linear bearing, said vibrating means comprising an hydraulic actuator having a bi-directionally movable ram and means linking said ram to the bottom end of said ejection rail so that ram movement is translated into z-axis seat movement, said vibrating means being located within said cockpit, said hydraulic actuator being disposed perpendicular to said z-axis, and said linking means comprising a rotatable bell crank and a link; and means for controlling the frequency and amplitude of said vibration in such a way as to provide an occupant of said seat with vibration Sensations similar to those experienced in the operational aircraft during buffeting.
