An Efficient Design Solution for a Low-Cost High-G Centrifuge System

The development of high-gravity centrifuge systems (HCSs) for G tolerance training has been justified from both safety and economic perspective. A low-cost HCS can provide a crucial standpoint toward an accessible simulator saving aircrews' lives and air assets during flight operations; however, there are several challenges associated with the design and development of a low-cost HCS. These challenges are a result of the strength and stability of the structure, capability of the main actuator, durability of the subfloor footing system, and cost of preventive maintenance. This article discusses design and development of an efficient and low-cost HCS, named Cyclone. The system has the capability of generating a maximum sustained acceleration of 9G with an onset rate of 5 G/s. Cyclone has a modular design, a capable rotary main drive, and a self-balanced structure with an effective centrifuge radius of 5 m. The design and development steps of the system, including the mechanical design, motion analysis, and structural analysis, are described. These steps have been implemented to meet the highest level of safety for a human-capable system providing an isolated and repeatable motion and force fields for air force aircrews and aviation medicine specialists to take greater advantage of the system for the purpose of effective centrifuge training and aerospace medicine research. The experimental results of test scenarios are shown. The system has not been human-rated, and this step is currently under investigation.
