Introduction

Overlap self-deployer Model 1/2 OL-SD is a self-

extending, non motorized unit capable of deploying a

60-foot-long (18.29 meters) Tubular Extendible Element

(TEE). The mechanism consists of three major components:

■ Cradle and Release Device

■ Tubular Extendible Element (TEE)

■ Storage Spool Assembly

In the stowed configuration, the TEE is wrapped and

stored on the Storage Spool Assembly and secured to

the cradle by the release device. Deployment is initiated

(18.29 meters)

Diameter: 0.5 in (1.27 cm)

maximum

Configuration: Overlap

Material: Beryllium Copper,

0.002 in thick

(0.0508 mm) thick

Thermal Control Silver or Gold with

Coating: Kapton

(if required)

Weight: 8.30 gr/ft

(27.24 gr/m)

Height: 3.25 in (8.26 cm)

Length: 2.812 in

(7.143 cm)

Total Unit Weight: 1.75 lbs (0.79 kg)

Drive System: Element Strain

Energy

Release Device: Pyrotechnic Piston

Actuator

Deployment Rate: Approximately

72 in/sec

(182.88 cm/sec)

Operating

Temperature Range: -54°C to +71°C

by activating a pyrotechnic squib-pin-puller device which

releases a caging strap. A release ejector-spring

provides initial deployment assist for the TEE and the

spool assembly. Deployment continues as the TEE uses

its own stored spring-energy. At full-deployment, the

storage spool assembly is automatically ejected. This

deployment mechanism is designed to meet the

requirements of document MIL-A-083577A (USAF)

General Specification for Moving Mechanical

Assemblies for Space and Launch Vehicles.
