TiNi’s Separation Link is similar to the “Sep Nut” concept, however it is designed to release a Tie Down link using Arms which swing out of the way upon application of power. This device leverages our ERM through a simple linkage to amplify the force capability by an order of magnitude. The embodiment shown is capable of 10,000 lbf and currently under qualification.
TiNi’s Cable Release Device was developed jointly with our partner company in Japan (Wel Research). The device uses a TiNi standard Pinpuller which is coupled to a swing arm mechanism that provides a significant gain in the hold down and release force. This can be configured to work with a single cable termination point, or dual as shown.
TiNi’s Pinpusher is yet another derivative of our Pinpuller technology. The embodiment shown has a relatively narrow body diameter and long Pin stroke. It also incorporates custom electrical switches which were designed to provide both a shut off function as well as telemetry.
TiNi’s SMA Cylinder was developed for a remote Down Hole application for the oil and gas industry. The project required high actuation force in an environment that could reach very high temperature’s (150C). TiNi was successful in developing the Actuator shown which mimics a hydraulic cylinder. However in this case the Actuator is electrically powered rather than using complicated mechanical systems.
TiNi Rotary Actuators operate on the same basic principal as our Pinpullers. However, the TiNi trigger is used to release energy stored in a preloaded Torque Spring (rather than Compression). Output Torque and Angle are scalable but typically extend up to 15 in-lb (1.6 Nm) and 180 degrees, respectively.
TiNi’s Launch Lock Actuator was originally nicknamed as, “The Jack” for the basic function that it provides. It uses an array of SCSMA cylinders (much like bullets in a revolver) to provide forces up to 50,000 lbf and displacements up to 0.25 in. The work output is greater than any non-pyrotechnic Actuator on the market.
TiNi’s Separation Nut works on the basis of a traditional segmented nut which is made to separate on command to release a tie down bolt. TiNi’s mechanism, however, is fully reusable and field resettable and uses two independent TiNi Pinpullers as the means for actuation to offer the utmost in redundancy and reliability.
Fail Safe Actuator
TiNi’s Fail Safe Actuators have many applications, but are fundamentally born out of the need to push or pull an appendage, in case something goes wrong in a critical component. These actuators are characterized by having relatively low-force, high-stroke, and their ability to maintain position without the application of power.
SMA Retaining Ring
TiNi’s “Releasable Retaining Ring” was an early prototype demonstrating how SMAs can be used in fire safety applications. In this case, a Shape Memory Alloy extension spring was used to detach a high force Retaining Ring thereby disabling critical munitions system.
TiNi’s Cut & Release Actuator was developed for a unique subsea application where a Fiber Optic cable assembly needed to be Cut & Released, on command. This was done by using two of our P50 Pinpullers in an orthogonal fashion to minimize mounting footprint. The custom developed interface included special adapters that provided both the Cutting and Release functions.
Fail Safe Actuator
TiNi FS04-5 Fail Safe actuator was jointly developed by TiNi Aerospace and the Jet Propulsion Laboratory (Pasadena CA) to be used as part of the rotating calibration mirror mechanism of the MIRO instrument. This flew on the historic flight to Comet 67 aboard the European Space Agency’s Rosetta spacecraft. The unit incorporates redundant Shape Memory Alloy (SMA) wires as the means to de-couple the Aperture Cover Window from the drive mechanism in the event of a motor failure.
