An inflator-based system provides for the actuation of valves and other devices using automotive air bag inflators, for example. One or more inflators can be connected to a valve body with an adapter such that upon inflator activation, inflator gases can act on a piston or similar device to achieve desired movement or operation of the valve or device. An inflator-based actuator can provide for a single action or multiple actions of a valve or other device. Such a system can provide safer and more reliable alternatives to electro-explosive ordnance devices found in pyrovalves, for example. Other uses for an inflator-based actuation system can include a lanyard pull initiator, a dual cartridge cutter, a bolt cutter, a hot gas generator (HGG) body, and a HGG pressure cartridge, to name a few examples.

Systems and methods for inflator-based actuation

An unmanned aerial vehicle (UAV) system provides for UAV deployment and remote, unattended operation with reduced logistics requirements. The system includes a launcher that can include one or more launch tubes, each launch tube configured to house a UAV in a canister and one or more gas generators operatively connected to each canister and configured to push the UAV out of the launch tube by releasing gas into the canister. A controller for activating the gas generators can sequentially, and with a predetermined time delay, expel the UAV with a desired velocity and acceleration. The system further includes a UAV recovery device, a power supply, a security subsystem, a command and control subsystem and a communications subsystem. Command, control and communications can be provided between a remote station and the UAV.
