Hydraulic Designers Fight Heat Effects

Conventional hydraulic fluids and component materials can’t fulfill heavy demands of new hydraulic services or withstand high hydraulic system temperatures caused by aerodynamic heating. Use of hydraulic boosted flight controls calls for high response rates and raises such new problems as resonance and coupling between hydraulic system pressures and airframe deflections.
