The ERM is a derivative of the BE2K Ejector (See Custom Actuators).   The principal of operation is that a bolt is threaded into the coupler section of the Actuator and used to secure a spacecraft deployable.  On command the coupler section is released by powering the Actuator. The ERM is a uniquely simple and effective device which offers the following key features: High Load Capacity The range of ERMs currently available have load capability of between 500 and 4000 lbs. Simple Mounting The ERM mounts to the structure via a two-point mounting flange and connects to the deployable via a single bolt threaded into the coupler. Fast Function Time The ERM can jettison the deployable with a standard pyro pulse limited to 5 amperes and 50 milliseconds. Simple Reset The ERM can be reset within seconds while still attached to the structure via a simple tool provided by TiNi Aerospace. High Life Cycle The ERM has a minimum life of 50 cycles. Redundant Firing Circuit As with all TiNi Actuators a redundant SMA circuit is incorporated.  This provides complete electrical redundancy as well as mechanical redundancy for the critical TiNi trigger element. Auto Shut-Off Switches Auto Shut Off Switches are incorporated making each ERM operational using a wide range of power levels. Misalignment Protection The ERM  has a swivel capability in which the Actuator housing can rotate up to ±5 degrees within the mounting enclosure.  This is an important feature for applications where the deployable is hinged and therefore traverses an arc as it is released. Custom Configurations As with all TiNi Actuators custom configurations are readily attainable with minimum effort. Detailed Specification See spec sheet for each model or contact TiNi Aerospace.
