FLY-ASS NOZZLE

SiC “Y”-TIP Nozzle

…. MAYBE THE ONLY ONE….

ONCE THE PROBLEM IS WELL UNDERSTANDED, THE SOLUTION IS EASIER TO FIND, RELATIVE ALSO TO TECHNOLOGIES THAT ARE SO USUAL BUT NOT COMPLETELY DISCOUNTED.

BY WELL ANALYZING THE THERMO-FLUODYNAMIC BEHAVIOR OF THE LAST PART OF THE NOZZLE, I HAVE DETERMINED THE DANGEROUS “ZONE” AND NOT ONLY REGARD TO ITS DURATION.

DESIGNING IT IN A CERTAIN WAY, I UNDERSTAND HOW THE ENTIRE SYSTEM COULD DRAW CONSIDERABLE ADVANTAGES ALSO TO THE PRINTING PROCESS AND ITS QUALITY.

SO, AS THE “Y” SHAPE OF THE LAST SECTION, CONFIRMS HOW THE MONOLITHIC BUILDINGS BENEFIT IT, FOR CERTAIN ANGLE OF INCLINATION AND FOR CERTAIN LENGTHS OF THE CONICAL OUTLET SECTION

“Y” SHAPE THAT DETERMINES NOT SO MUCH AN “END-POINT”, AS A REAL “CRUCIBLE” OF MELTING BEFORE BECAME AN OUTLET.

CONFIRMED THE THEORY, THE PRACTICE HAS JUST BEEN MORE COMPLEX, NOT BOTH FOR THE CHOICE OF THE CORRECT MATERIAL, BUT FOR THE DIMENSIONS WITH WHICH THE SHAPE RELATIVE TO THE DANGEROUS AREA HAD TO BE MADE.

IN ANY CASE, THE BEST “IDEAL” MATERIAL FOR THE OUTLET AREA OF THE NOZZLE WOULD BE DIAMOND.

BUT, BEING SATISFIED IF JUST HAVE:

•  HARDNESS NEAR THE DIAMOND FOR DON’T SUFFER THE WEARING
•  HIGH THERMAL CONDUCTIVITY, (AT LEAST THE SAME OF BRASS) FOR DON’T BECAME A “COLD” POINT AND FOR THE BEST THERMAL CONDITION
• VERY LOW FRICTION COEFFICIENT, ESPECIALLY IN CONTACT WITH HIGH TEMPERATURE FLUIDS FOR ITS BEST SLIDING
• HIGH RESISTANCE TO THERMAL SHOCKS FOR DON’T SUFFER THE HIGH “ΔT” BETWEEN ITS EXTERNAL AND INTERNAL SURFACE
• GOOD ELECTRICAL CONDUCTIVITY (AT LEAST THE SAME OF BRASS), SINCE MANY PRINTERS LEVEL THE TABLE WITH AN ELECTRIC SIGNAL,
• PRODUCTION PROCESS THAT DOES NOT LIMIT THE CONSTRUCTION OF “IDEAL” GEOMETRIES TOO MUCH

AT THE MOMENT I DON’T THINK THERE CAN BE SOMETHINGS BETTER THAN SiC…….. BEYOND DIAMOND…..BUT I LOOK FORWARD TO WELCOME UPDATES.

ABOUT THE DATA RELATING TO ITS PHYSICAL-MECHANICAL PROPORTIES, I REFER TO THE DEDICATED PAGE WITHOUT MAKING COMPARATIVE TABLES… ..I THINK IT IS NOT NECESSARY.
