Application Briefs
Valves and manifolds are historically
produced via subtractive machining,
with boring tools removing unwanted
material to construct their radial passages
within a single metal block. The radial
passages are typically cylindrical or
slightly frustoconical in nature. This design
approach allows for passages that expand
in two dimensions. By introducing
a third dimension through AM, however,
Marotta has improved those passage features
to achieve desired performance.
Marotta's patented approach starts
with a 3D CAD model of choice that can
meet varying ranges of end application
specifications. Via the SLS machine, powdered
metal is fused together layer by
layer to construct a solid, single-pieced
component with three-dimensional passage
structures that can vary in shape-
diamond, horizontal dome, spindle,
branch-like, and others.
Marotta has evaluated its 3D valve concept
in more than a dozen design configLoitering

U
Vision Air Ltd., a company that specializes
in loitering munitions systems
of all sizes for a variety of missions,
is marketing its Hero-120 and
Hero-400EC Loitering Munition systems
with anti-tank capability, providing
an all-inclusive solution for countering
MBTs (main battle tanks). Hero
Loitering Munition systems provide an
accurate, effective, and highly lethal response
to hard targets. They are capable
of locating hidden targets, tracking
them and attacking at significantly
longer ranges than commonly available
anti-tank guided missiles (ATGM).
As members of the HERO series of loitering
munition systems, both the
Hero-120 and Hero-400EC can carry
multi-purpose warheads for extended
lethality against a wide range of targets,
as well as having unique attack capabilities
from any direction and angle, including
top attack. With long endurance
and low acoustic, visual and
thermal signature, the systems can locate,
track and strike static and moving
targets with pinpoint accuracy. The
ability to launch Loitering Munitions
from a remote-controlled multi-canister
launcher provides effective deployment
of the Hero systems from a variety of
platforms - air, land and sea - away from
enemy lines.
The Hero-30 Loitering Munition System,
developed and manufactured by
UVision, incorporates a high level of
precision attack and abort capabilities.
This simple-to-operate system enables
front-line forces to initiate operations,
as well as to respond to any enemy target
or threat that arises, and eliminate it
with extreme accuracy. The Hero-30's

as is the part's impact on the overall
manifold's production and performance.
Founded in 1943, Marotta Controls'
current product portfolio includes pressure,
power, motion, fluid, and electronic
controls for tactical systems, shipboard
and sub-sea applications, satellites, launch
vehicles, and aircraft systems.
