AN APPARATUS TO DETERMINE THE CHARACTERISTICS OF SOLID PROPELLENT

摘要

THE INVENTION DISCLOSED A STATIC BED FOR DETERMINATION OF SOLID PROPELLANT CHARACTERISTICS. THE SOLID PROPELLANT (60) IS CYLINDRICALIN FORM AND HAS A SYMMETRICALLY POSITIONED CYLINDRICAL BORE THEREIN FORMING A CHAMBER. THE STATIC THRUST BED CONSISTS OF A CYLINDRICAL COMBUSTION CHAMBER (18) WITH A CLOSED END AN OPEN END, A TROLLEY (22) MOUNTED ONTO WHEELS (24) AND ONTO WHICH THE CYLINDRICAL COMBUSTION CHAMBER (18) IS SECURELY MOUNTED AND A LOAD CELL (16) TO DETERMINE THE THRUST GENERATED WHEN THE SOLID PROPELLANT (60) IS IGNITED. THE LOAD CELL CAN EITHER BE OF THE CANTILEVER LOAD CELL TYPE (16) OR OF THE CYLINDRICAL LOAD CELL (36). IN THE EVEN A CANTILEVER LOAD CELL (36) IS USED , A BAYONET (14) IS CONTECTED TO A CLOSED END OF THE CYLINDRICAL COMBUSTION CHAMBER (18). MEANS TO IGNITE THE SOLID PROPELLANT AND MEANS TO DETERMINE THE TEMPERATURE IN THE COMBUSTION CHAMBER ARE INCORPORATED IN THE CHAMBER.(FIG.1)
