ACME US Army RAH-66 Comanche 3D Seat Design

Project Overview: ACME designed Dynamic Motion Seat Systems to provide the motion cues for the RAH-66 Comanche Mission Simulator.  The seats were representative of the actual Comanche aircraft seat in appearance as well as function.

ACME Services Used: Mechanical Engineering, Software Engineering, Systems Engineering.

Project Details: The Dynamic Motion Seat System for the RAH-66 Comanche mission simulator consisted of the motion seat, support electronics, and software to provide the motion cues required during pilot training.

The seat was representative of the actual Comanche seat in appearance and function.  This included the relative position within the simulator, shape of the bucket, as well as cushions and restraints.  The Comanche seat adjustments were also incorporated into the Dynamic Motion Seat.  The side stick controller and jettison handle mounting provisions were included in the design of the seat.

The Dynamic Motion Seat System provided motion cues in four axes of control, one each for sway and surge and two for heave.  The seat also incorporated a sonic transducer for vibrations felt through the seat pan.

Covers and closeouts were designed to prevent access to moving parts when the seat is in use, while providing access for maintenance.  A weight-on-seat switch and consent interlocks were used to ensure safe operation of the seat.
