| Abstract | Aircrew of a modern combat aircraft is exposed to hazardous effects of high G-forces and high angular velocities. In order to protect human lives and to avoid material losses, High-G training in human centrifuge is used to artificially increase accelerative force under controlled conditions. In this paper, centrifuge is modeled as 3 DoF revolute robot manipulator with planetary, roll and pitch axis. Pilot seat is controlled as last unit of robot manipulator. Control system is obtained by adding new functionalities for flight simulation in control unit for robot programming previously developed and by implementing solutions for the kinematics and dynamics of this robot. Standard open-loop flight simulations imply predefined profiles of absolute acceleration in the gondola of the centrifuge. It is necessary to develop algorithms for controlling this acceleration. An algorithm for calculating the angular velocity of main arm of human centrifuge which provides predefined profile of absolute acceleration in gondola of centrifuge, where the onset rate of absolute acceleration is constant, is developed. As a solution of nonlinear differential equation, Jacobi elliptic function appears. Results obtained by developed algorithm are compared with results obtained by simulation in Simulink. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
