Pressurized gas driven vehicle and methods for charging and launching it

A pressurized gas driven vehicle comprising:

• a body defining a pressure chamber;
• nozzle means mounted on said body having inlet conduit means communicating with said pressure chamber to conduct pressurized gas thereto, said nozzle means also having jet outlet passage means communicating with said pressure chamber and being positioned to direct pressurized gas flowing therethrough in a direction generally opposite to the desired path of said vehicle,
• valve means for checking back-flow of pressurized gas through said inlet conduit means;
• and
• electrically conductive jet outlet passage cover means, disintegratable when electric current is conducted through it, attached to said nozzle means for sealing said outlet passage means prior to being disintegrated and for rapidly releasing pressurized gas stored in said pressure chamber through said outlet passage means to propel said vehicle when disintegrated by electric current conducted through it.
