Method and means for forming a gaseous passage

Claim 1

A METHOD FOR PROGRESSIVELY FORMING A CONTINUOUS NOZZLE PASSAGE AT AN AFT END OF A ROCKET DEVICE, SAID ROCKET DEVICE FORMED ON A LONGITUDINAL AXIS AND HAVING AN EROSIVE TYPE OUTER CASING, A BURNING TYPE MAIN SOLID PROPELLANT MEANS AND A BURNING TYPE SECONDARY SOLID PROPELLANT MEANS BETWEEN SAID OUTER CASING AND SAID MAIN PROPELLANT MEANS COMPRISING THE STEPS OF: PROGRESSIVELY AND CONTINUOUSLY DISCHARGING A MAIN PROPELLANT GAS STREAM WHEN SAID MAIN PROPELLANT MEANS BURNS FROM AN AFT END TO A FORE END THEREOF ALONG SAID AXIS; PROGRESSIVELY AND CONTINUOUSLY DISCHARGING A SECONDARY PROPELLANT GAS STREAM AROUND SAID MAIN PROPELLANT GAS STREAM WHEN SAID SECONDARY SOLID PROPELLANT MEANS BURNS FROM AN AFT END TO A FORE END THEREOF ALONG SAID AXIS; MAINTAINING THE PROGRESSIVELY MOVING BURNING AFT ENDS OF SAID MAIN SOLID PROPELLANT MEANS AND SAID SECONDARY SOLID PROPELLANT MEANS A PREDETERMINED DISTANCE FROM EACH OTHER; PROGRESSIVELY AND CONTINUOUSLY ERODING SAID EROSIVE TYPE OUTER CASING FROM AN AFT END TO A FORE END THEREOF ALONG SAID AXIS; MAINTAINING THE PROGRESSIVELY CHANGING BURNING AFT ENDS OF SAID SECONDARY SOLID PROPELLANT MEANS AND SAID OUTER CASING A PREDETERMINED DISTANCE FROM EACH OTHER; AND PROGRESSIVELY FORMING A CONTINUOUS GASEOUS PASSAGEWAY OF PREDETERMINED CONFIGURATION TO GUIDE AND CONTROL THE EXPANSION OF SAID FIRST GAS STREAM.

Claim 2

A METHOD FOR PROGRESSIVELY FORMING A CONTINUOUS NOZZLE PASSAGE AT AN AFT END OF A ROCKET DEVICE, SAID ROCKET DEVICE FORMED ON A LONGITUDINAL AXIS AND HAVING AN EROSIVE TYPE OUTER CASING, A BURNING TYPE MAIN SOLID PROPELLANT MEANS AND A BURNING TYPE SECONDARY SOLID PROPELLANT MEANS BETWEEN SAID OUTER CASING AND SAID MAIN PROPELLANT MEANS COMPRISING THE STEPS OF: PROGRESSIVELY AND CONTINUOUSLY DISCHARGING A MAIN PROPELLANT GAS STREAM WHEN SAID MAIN PROPELLANT MEANS BURNS FROM AN AFT END TO A FORE END THEREOF ALONG SAID AXIS; PROGRESSIVELY AND CONTINUOUSLY DISCHARGING A SECONDARY PROPELLANT GAS STREAM AROUND SAID MAIN PROPELLANT GAS STREAM WHEN SAID SECONDARY SOLID PROPELLANT MEANS BURNS FROM AN AFT END TO A FORE END THEREOF ALONG SAID AXIS; MAINTAINING THE PROGRESSIVELY MOVING BURNING AFT ENDS OF SAID MAIN SOLID PROPELLANT MEANS AND SAID SECONDARY SOLID PROPELLANT MEANS A PREDETERMINED DISTANCE FROM EACH OTHER; PROGRESSIVELY AND CONTINUOUSLY ERODING SAID EROSIVE TYPE OUTER CASING FROM AN AFT END TO A FORE END THEREOF ALONG SAID AXIS; MAINTAINING THE PROGRESSIVELY CHANGING BURNING AFT ENDS OF SAID SECONDARY SOLID PROPELLANT MEANS AND SAID OUTER CASING A PREDETERMINED DISTANCE FROM EACH OTHER; AND PROGRESSIVELY FORMING A CONTINUOUS GASEOUS PASSAGEWAY OF PREDETERMINED CONFIGURATION TO GUIDE AND CONTROL THE EXPANSION OF SAID FIRST GAS STREAM.
