Propulsion System Flow Stability Program (Dynamic). Part II. RA-5C Accommodation Control System Analysis.
Abstract
Propulsion systems conventially operate below optimum steady-state performance levels in order that adequate stability margins be available during off-design and transient operation. An ideal 'accommodation' control system would schedule operation for near optimum steady-state performance, and provide additional stability margins only when required to accommodate transients. Such a system has been synthesized for the RA-5C/J79-8 propulsion system. Hybrid computer and digital computer simulation programs were used in defining and checking performance of the accommodation control system. Simulation results show that the digital-computer-centered control system successfully accommodated all the transients to which the propulsion system was subjected. The accommodation control system component requirements are within the current or near-future state of the art. However, the need for development of high temperature sensors with increased dynamic response is indicated. (Author)
