Actuators

ARQUIMEA Actuators Group is specialized in the development of low-shock non-explosive actuators for Space applications. Based on our proprietary Shape Memory Alloy (SMA) material, so called SMARQ, we can provide any type of actuator (linear, rotary, hold down and release, break, smart valves...) qualified for spaceflight operation in an extended temperature range from -90oC up to +125oC. SMARQ is immune to radiation, immune to magnetic field and immune to electromagnetic jamming.

ARQUIMEA Actuators Group is open to work with our Customer engineers to adapt our actuators to the interface and requirements of your application. Either for Satellite or Launcher mechanisms, SMARQ technology is well suited to meet your requirements.

SMARQ Actuators can be used in satellite Hold-Down and Release Mechanisms (HDRM) and also on Deployment Mechanisms (DM). Most spacecraft have appendages (Solar Arrays, Antenna Reflectors, Radiators, Instruments, Doors, Sensors, Booms, etc.) that are held stowed during launch, in order to fit into the available launcher volume and survive launch loads, and then later deployed in orbit into their operating position.

Other equipment like scanning/refocusing mechanisms, Electric Propulsion Pointing Mechanisms or Coarse Pointing Mechanisms, shall be stowed during launch and released once in orbit in order to allow on station operations without any specific deployment.

To achieve these functions, two different types of low shock non-explosive mechanisms are used one after the other, HDRMs and DMs.

HDRMs are standard components for spacecraft to achieve mission related critical functions. Their main functions are to secure during launch and to release once in orbit, or during descent to/on planetary surface, movable payload items, deployable appendages and separable mission elements. They can also be used in order to achieve timely synchronization for the deployment and/or ejection of specific appendages or separable mission elements.

DMs are used to enable deployment of a released appendage from its stowed position to its operational position following a defined set of kinematics and passive-to-active controlled dynamics. Once the final position is reached, the appendage is either latched at a defined position or the DM is used as a re-pointing or trimming device in order to achieve specific mission related functions.

SMARQ based low-shock non-explosive actuators provide high load and minimum release shock. SMARQ rotary actuator for DM allows an electrically controlled deployment, avoiding springs and, therefore, avoiding the need for shock absorbing devices or brakes. Also, SMARQ actuator technology is highly reliable due to its built-in redundant design (multi-fiber approach) and it allows easy mechanism testing during AIT due to its electronic resettable function.

Pin Pullers (actuators)
Pin Pullers

Pin Puller actuators are low-shock non-explosive SMA based mechanical devices in which a pressure cartridge causes a pin or piston to retract inside the structure frame, usually against a side load. In the extended position, the pin or output shaft can be seen to be loaded by a compression spring. The pin remains firmly locked in this position due a mechanical components block stroke.

HDRM (actuators)
HDRM

Low-shock non-explosive Hold-Down and Release Mechanisms (HDRM) are mechanical devices which function is to hold-down a mechanical system to the time it has to be released or deployed for operation. Its mechanical design has been conceived for optimizing device’s weight, reducing parts complexity and achieving a suitable stiffness.
