  • Securement and release mechanisms for spacecraft
    Patent number: 11518551
    Abstract: A carrier of a spacecraft can include multiple latch assemblies that are linked together and held in place by one notched bolt or main shaft, which is out of the main load path. The latch assemblies secure the payload (e.g., CubeSat device) within a carrier by interfacing with pin assemblies on the payload. To deploy the payload, the shape memory alloy actuator is fired which causes a series of springs and preload forces to rotate latches of the latch assemblies out of the path of the pin assemblies. Once the latches are out of the way, the payload is deployed by a spring-loaded pusher assembly and guided through deployment using rollers. Each latch assembly is preloaded in tension using a corresponding preload lug of a receiver assembly.
