METHOD OF TESTING OF CHARGES ATTACHED TO THE HOUSING OF SOLID PROPELLANT ROCKET ENGINES Russian patent published in 2017 - IPC F02K9/96 

FIELD: rocket construction.

SUBSTANCE: invention relates to rocketry, namely, to solid-propellant rocket engines, and, in particular, can be used in testing of attached to the housing large-sized charges in rocket systems of various purposes, mainly used on mobile carriers road or railway type. When testing attached to the housing solid fuel rocket engine charge temperature control of charge at forced loads is performed as well as subsequent verification of serviceability by fire bench tests. Charge is exposed to serial application of static and repeatedly alternating forced loads, level and duration of which is determined from the condition of parity of accumulated damages in charge in the mode of standard operation and at forced tests. Immediately before fire bench tests control of structural integrity of attached charge is performed.

EFFECT: invention provides higher reliability and reduced duration of tests of charges attached to the housing of solid propellant rocket engines.
