Moog specializes in the design, manufacture, and integration of turret stabilization and fire control systems for military vehicle platforms. Their technology supports weapon stabilization, fire control, and seamless integration on manned and unmanned turrets.
The Flexible Mission Platform (FMP™) is a mission-agnostic system designed for use across various platforms including vehicles, ships, and trailers. It can host various payloads and offers features like Moog's high-performance stabilization and weapon stores management.
A common movable element on spacecraft is the communication (or radar/microwave) antenna. Antenna Pointing Mechanisms (APMs) have long been used to perform the vital function of pointing the antenna bore sight to its target and tracking to maintain the RF link to the spacecraft. APMs are typically two-axis gimbals, providing options for full hemispherical coverage or configurations ideal for tracking satellites in Low-Earth Orbits (LEO). These mechanisms include several approaches to electrical cable management and may integrate RF rotary joints if needed.
The Moog Type HT-1 Rotary Incremental Actuator is a new addition to the rotary actuator product line. It is a compact, closely integrated coaxial design composed of a small size permanent magnet stepper motor driving the output stage through a gear transmission consisting of a larger size harmonic drive.
The Micro3 rotary incremental actuator is a compact, closely integrated design made up of two key elements: a rotary actuator and a standard Type 3 speed reducer and output flange. The motor is a small angle permanent magnet stepper with relatively high holding torque.
The UPT3 is a closely-integrated package that utilizes all available space to significantly increase performance and reliability. While design and performance margins are elevated with the introduction of this actuator, key interface envelope dimensions of the Moog heritage Type 3 are preserved in order to facilitate interchangeability.
The M8 Rotary Incremental Actuator is a compact, closely integrated design made up of two key elements: a motor and a harmonic drive speed reducer. The motor is a small angle permanent magnet stepper with relatively high holding torque.
The Rotary Actuator consists of a small-angle permanent magnet stepper motor coupled with a Harmonic Drive Speed reducer, with a large rotating output flange member. The family of Rotary Actuators is based on heritage design with a wide range of step sizes available. The options include Stepper or Brushless DC Motors, Direct Drive and Gear Transmissions, as well as several options for position feedback such as optical encoders, resolvers, potentiometers, and hall effect sensors.
The Type 11 biaxial gimbal as shown consists of two Type 1 actuators in an orthogonal combination. The Type 1 actuators can be provided with a variety of options. These gimbals can be used for two-axis antennae or solar array drives.
The Type 55 biaxial gimbal assembly is a robust two-axis gimbal which is right-sized for supporting and positioning the majority of larger payloads. It is based on the Moog Type 5 rotary incremental actuator. The gimbal can be configured for limited rotation, with the inclusion of range-defining hard stops on the actuator outputs, or, for continuous rotation on one or both axes with the integration of a slip ring assembly.
The Type 33 Biaxial Gimbal is of a size appropriate for many antennas, and it has become by far our most popular Antenna Pointing Mechanism configuration. Available in either Elevation/Azimuth or X/Y, these units have proven their reliability and versatility many times over.
The Type 22 antenna positioner assembly is a compact two-axis gimbal which is ideally suited for supporting and positioning small to medium-sized spacecraft communications antennas. It is based on the Moog Type 2 rotary incremental actuator.
Electrohydrostatic (EHA) actuators offer highly reliable, two-fault tolerant steering control solutions. With EHA actuation, the motor works through gears and the output of a pump directly actuates a conventional hydraulic piston, providing enhanced reliability for future man-rated space vehicles.
Electrohydraulic (EH) actuators produce force by a hydraulic power unit (HPU) which includes electric motors, pumps, reservoirs, relief valves, check valves, and associated plumbing. They enable precise control by employing electrohydraulic servovalves, converting current input signals into controlled fluid flow.
