Hybrid Control Components, Fluidic: Hydromechanical Interface Study.
Abstract
A 'pinch tube' concept was evaluated as a fluidic-to-hydromechanical interface for application to gas turbine engine control systems. The particular application selected for implementation in prototype hardware was a fuel flow valve for small gas turbine or ramjet engines. Based on initial testing of a ponch tube which utilized only fluid interactions, it was established that a mechanical advantage would be required to multiply the low-level fluidic signal (plus or minus 5 psid) to a high-level hydraulic signal (700 psia). Bench testing of a prototype pinch tube, using a 4-inch diameter force multiplying piston, demonstrated comparatively high slew rates and an insensitivity to Mil Spec vibration. However, significant non-linearities and hysteresis were evident. (Modified author abstract)
