Typical Technical Specifications:

Introduction

Hingelock deployer Model 621 was originally developed

for the San Marco D/L satellite. Two such units, located

180° apart, were deployed to form a

dipole antenna along the Z-axis as part of a 3-axis

Electric Field Experiment. This motorized mechanism is

capable of extending and retracting a 0.5 in (1.27 cm)

diameter Tubular Extendible Element (TEE). The deployer

features electrical and mechanical stops at both

full-extension and -retraction. A potentiometer, driven by

the moving element, provides a continuous indication

of deployed length. This deployment mechanism is de-

signed to meet the requirements of document MIL-A-

083577B (USAF) General Specification for Moving

Mechanical Assemblies for Space and Launch Vehicles.

Similar units were used on the Radio Astronomy Explorer

(RAE-B) Satellite.
