Starting with the presently recognized requirements of accelerations, levels of various exposure conditions, and combinations of stresses in aerospace systems, a design study was made of an acceleration research device which would simulate these conditions. It was required that this accelerator use proven construction methods and be economically feasible. In simulating the various performance requirements there were certain areas that were quite significant in the over-all design: (1) Power requirement during the first second of maximum centrifuge onset is approximately 86,000 horsepower and necessitates a stored energy means to keep electrical power requirements below 20,000 horsepower; (2) Gyroscopic actions plus simulated vibration conditions at the end of the centrifuge arm dictate that major attention be given to arm natural frequencies and dampening qualities; (3) Resultant acceleration effects plus cab inertias necessitated some reduction in cab RPM's and onset rates to keep torque and horsepower requirements within feasibility limits; and (4) Coriolis forces must be considered in both the effect upon the subject being tested and cab structure.

The report fulfills the following objectives: (1) Presents a tentative configuration and performance of a centrifuge and facility that best fits present and anticipated weapons systems. (2) Evaluates and adjusts the centrifuge design with respect to the research value of a specific performance requirement and its associated cost. (3) Presents a design which can be built with present-day knowledge and with assurance of meeting performance requirements. (4) Presents a design complete enough in detail to show its feasibility and to establish an estimated cost. (5) Recommends staging of construction and the staff personnel necessary to maintain and operate the facility.

Winner of the Shingo Publication Award Accelerate your organization to win in the marketplace. How can we apply technology to drive business value? For years, we've been told that the performance of software delivery teams doesn't matter―that it can't provide a competitive advantage to our companies. Through four years of groundbreaking research to include data collected from the State of DevOps reports conducted with Puppet, Dr. Nicole Forsgren, Jez Humble, and Gene Kim set out to find a way to measure software delivery performance―and what drives it―using rigorous statistical methods. This book presents both the findings and the science behind that research, making the information accessible for readers to apply in their own organizations. Readers will discover how to measure the performance of their teams, and what capabilities they should invest in to drive higher performance. This book is ideal for management at every level.
