Introduction

Hingelock deployer Model 358 was developed for the
International Sun-Earth Explorer (ISEE-3) satellite. Two
such mechanisms, located 180° apart, were used to form
a dipole antenna along the Z-axis as part of
the 3-axis Radio Mapping Experiment. This
motorized mechanism is capable of extending and
retracting a 1.12 inch (2.86 cm) diameter by 32.8 foot
(10 meters) long Tubular Extendible Element (TEE).

The deployer features electrical and mechanical stops at
full-extension and –retraction. A potentiometer, driven
by the moving element, provides a continuous indica­tion of deployed length. This deployment mechanism is
designed to meet the requirements of document
MIL-A-083577B (USAF) General Specification for Moving
Mechanical Assemblies for Space and Launch Vehicles.
This unit can deploy and retract in orbit.
