Abstract: Aspects of the disclosure relate to flight termination systems for aerial vehicles having envelopes. For instance, a flight termination system may include one or more heat sources mounted on the top plate and oriented towards envelope material of the envelope. The one or more heat sources may each include a gas generator configured to generate gas of sufficient temperature to melt the envelope material and vent lift gas from the envelope. The flight termination system may also include a drag device arranged at the top plate which may be being configured to provide stability to the envelope during descent.

Abstract: The technology relates to techniques for an aquatic energy discharge system for an energy storage system of an aircraft. An aquatic energy discharge system can include an energy storage system, a pair of electrodes coupled to the energy storage system, and a water detection system configured to detect a water landing. The electrodes can be configured to submerge in a body of water after the aircraft has landed in the body of water, and cause a hydrolysis reaction that drains energy from the energy storage system in response to the water detection system detecting the water landing. A method of discharging an energy storage system of an aircraft can include detecting that an aircraft (or portion thereof) has landed in a body of water, and discharging the energy storage system by powering a hydrolysis reaction using a pair of electrodes.
