This specification covers the general requirements for electrical solenoids used to actuate various devices through the conversion of electrical signals into mechanical motion. These solenoids are of the axial stroke type and the rotary stroke type.
This Aerospace Recommended Practice (ARP) specifically discusses five configurations of flexible tubing. The design data given will aid in design of coiled tube assemblies using Ti-3Al-2.5V cold worked, stress relieved (CWSR) tubing per specification AMS4944. It should be noted that a particular system operating pressure level is not specified. The configurations discussed should be compatible with pressure levels up to 8000 psi upon completion of analysis for the actual stress and life requirement of the intended application. Formal qualification tests are recommended to verify satisfactory installation, clamping, and life of each unique design.
This recommended practice encompasses design, analysis, fabrication, and installation of pressurized plain metal tubing used in fluid power systems to provide relative motion. Specific data given are for MIL-T-6845 tubing ranging from 1 4" to 1" dia. used in 3000 psi hydraulic or pneumatic systems, Types I, II, III or IV applied to any type of vehicle. The flexible configurations of plain metal tubing are intended for application to actuators that oscillate about a pivot, to areas of large structural deflection such as reservoirs installation, and to areas of extreme environment where flexible hose could not survive.
This SAE Aerospace Recommended Practice (ARP) is intended as a guide to aid in the specifying and testing of direct acting three way, two position, single and multiple coil, normally open and normally closed solenoid valves used for the pilot actuation of hydraulic control systems and the control of hydraulic components. The information presented should be useful in standardizing terminology, in specifying requirements and performance parameters, and in defining test methods. The recommendations do not restrict or attempt to define the internal design features of solenoid valves. Standard mechanical, electrical and fluid porting interfaces are recommended to provide commonalty, interchangeability, design flexibility and to be more affordable. In general, this recommended practice is directed toward solenoid valves for use in military and commercial flight control and hydraulic actuation systems.
