5.2.5.2. Planetary Systems Motorized Lightband (MLB)
The Planetary Systems MLB, Figure 5.2.5.2-1, provides a fully qualified and flight proven low shock and
lightweight option for use on Minotaur missions. Multiple sizes of MLBs have previously flown on Minotaur
vehicles. The MLB uses a system of mechanically-actuated hinged leaves, springs, and a dual redundant
release motor to separate the upper ring (mounted to the spacecraft) from the lower ring. The MLB is
flexible and configurable to support various
separation force requirements and number of
required separation connectors. The MLB upper
ring interfaces to the spacecraft through holes in
the upper ring and remains attached after
separation adding approximately 2.04 kg (4.5 lb)
of mass. Due to the unique design of the system
and space constraints for tooling, Orbital provided
socket head cap screw mating hardware must be
inserted from the launch vehicle side. The MLB
offers the unique ability to perform separation
verification tests both at a component and system
level.
5.2.5.3. RUAG 937 Separation Systems
The RUAG 937S 38” separation system, Figure
5.2.5.3-1, is a flight proven, low-shock separation
system that offers outstanding load capability. This
system is composed of two rings and a clamp
band separated by a Clamp Band Opening Device
(CBOD) rather than traditional bolt cutters. The
CBOD uses a redundant, ordnance initiated pin
puller device to convert strain energy, created by
the clamp band tension, into kinetic energy
through a controlled event that greatly reduces
separation shock. Hardware separated with the
payload is approximately 6.2 kg (13.6 lb) for the
937S. Orbital-provided attachment bolts to this
interface can be inserted from either the launch
vehicle or the SV side of the interface.
