Test methods for static strength and static stiffness of launch vehicle structures

1 Scope

GB/T 47261-2026 is the Chinese national standard covering loading a rocket structure on the ground until it either proves itself or breaks - the load cases from flight, the test rig and its reaction structure, the instrumentation, the load steps and the criteria for a successful test. First edition, 20,000 words, in force since 1 October 2026. It was issued on 31 March 2026 and takes effect on 1 October 2026, as a first edition. The document is under the responsibility of the Standardization Administration of China. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document describes the test methods for the static strength and static stiffness of launch vehicle structures. This document applies to static strength and static stiffness tests of launch vehicle structures under ambient temperature conditions.
