BOLT TO ATTACH A MISSILE LAUNCHER TO THE BOLT OF A CARRIER PLANE.

摘要

THE FATIGUE RESISTANCE OF A BOLT FOR THE CONNECTION OF A TAKEOFF DEVICE FOR A FLYING ARTIFACT WITH THE PILL OF A NURSING AIRCRAFT MUST BE ELEVATED BY IMPEDIMENTING THE INTERIOR AND EXTERNAL SIZING EFFECT. THE BOLT IS PROVIDED WITH A HEAD (10) THAT HAS A SECTION (12) IN THE FORM OF A DISC OF LARGER DIAMETER AND AN EXISTING CYLINDRICAL SECTION (14) FOLLOWING A SMALLER DIAMETER, AND WITH A HANDLE (16) WITH A SECTION (18) CYLINDRICAL FLAT AND A SECTION (20) THREADED PLACED BELOW. THE BOLT IS A PIECE FORGED FROM A CHROME-MOLITENE-VANADIUM STEEL HIGHLY RESISTANT WITH HEAT TREATMENT AND WITH A COMPOSITION OF 0.4 C. 5 CR. 1.3 MO AND 0.5 V, WHICH AFTER HEAT TREATMENT HAS A FINE GRAIN COMPOSITION WITHOUT SAFETY ZONES. THE SURFACE IS TREATED IN A WAY THAT EXCLUDES FRAGILIZATION. THE CURVATURE GRADIENT OF THE INTERNAL EDGES IS GREATER THAN 0.6 MM. THE THREAD AND THE BOLT STEM ARE ROLLED. THE HEAD (10) OF THE BOLT SHOWS A STRESSING IN THE FORM OF SIDES OF INDOOR HOUSING OF SIX EDGES (26).
