摘要: Aspects of the disclosure relate to flight termination systems for tethered aerial vehicles. For instance, a flight termination system for a tethered aerial vehicle including an envelope may include a tool and a tether. The tool may include a first piece configured for attachment to an interior surface of the envelope and including a cutting blade. The tool may also include a second piece configured for attachment to an exterior surface of the envelope. The tether may be attached to the first piece such that when in use, a force on the tether causes the tool to cut an opening into the envelope.

摘要: The technology provides a launch rig structure capable of filling a very large balloon envelope while the balloon is arranged vertically. The filled balloon is capable of staying aloft in the stratosphere with its payload for months or longer. The launch rig structure is configured to rotate up to 360° in response to current wind conditions. It includes an integrated lifting boom and gas handling system to fill the envelope. A payload release assembly is configured to couple with a rigid connection member of the balloon, enabling the envelope to be filled while in a vertical orientation. The payload release assembly is part of a launch cart that is positioned within the interior space of the launch rig. A gripper assembly engages with the rigid connection member. Once the envelope is filled, the gripper assembly disengages from the connection member so that the balloon floats away from the launch rig.
