US Patent 12134456 Inflatable structure launching

According to one aspect, a system for launching an aerostat may include a reactor defining a chamber, an inflatable structure including a balloon and a neck, the balloon and the neck collectively defining a volume, a coupling defining a passage in fluid communication between the chamber of the reactor and the volume of the inflatable structure, the passage defining a longitudinal axis, and a collar supported on the reactor, the collar defining an orifice in fluid communication between the chamber of the reactor and the passage of the coupling, and the collar releasably restricting displacement of the passage of the coupling, the volume of the inflatable structure, and the chamber of the reactor relative to one another along the longitudinal axis.
