Program for the Critical Components of a Fly-by-Tube Backup Flight Control System. Part I.

摘要

This report presents the results of a program to develop two of the critical components in an advanced fluidic backup primary flight control system defined as the fly-by-tube concept. Components developed include an input transducer, which converts pilot commands into hydraulic differential pressure signals, and fluidic resistor networks that sum these hydraulic signals together to provide the required servoactuator commands. Results show that this concept which uses signal levels up to +400 PSID is accurate, linear, quiet, simple, low cost, relatively insensitive to changes in fluid viscosity, and has a stable null with adequate response.
