Detail of GJB 540.1-1988

Introduction of GJB 540.1-1988

Cruise missile strength and rigidity specification – General specification 1 Scope and applicability This standard specifies the general requirements for the design, analysis, test and required documents of load, structural strength and rigidity of cruise missile structures under launching, flight, vehicle-borne, ship-borne, transportation and handling conditions. This standard is a general specification, which is applicable to the ordering, design, analysis and verification of cruise missiles. This standard also serve as a basis for determining the development statement of work and the conclusion of the contract. Requirements for specific models shall be implemented in accordance with the development statement of work and contract terms and conditions. 2 Normative references GB1920 Standard atmosphere QJ500 Specification for carbon steel and alloy structural steel forgings QJ501 Specification for stainless, acid-resistant and heat-resistant steel and alloy forgings QJ502 Specification for aluminum alloy and copper alloy forgings QJ168 Specification for magnesium alloy castings QJ1028 Specification for spacecraft coordinate systems QJ1183-1185 Environmental specification for coastal defense missiles QJ1139 General specification for design and manufacture of tactical missiles QJ169 Specification for aluminum alloy castings 3 Composition of the standard series GJB540 consists of the following parts under the general title Cruise missile strength and rigidity specification: GJB540.1-88 General specification GJB540.2-88 Flight loads GJB540.3-88 Transportation and handling loads GJB540.4-88 Shipborne loads GJB540.5-88 Airborne loads GJB540.6-88 Other loads GJB540.7-88 Reliability requirements and repeated loads GJB540.8-88 Aeroelastic instability GJB540.9-88 Vibration GJB540.10-88 Ground test GJB540.11-88 Documents and reports 4 Symbols Symbol Description Unit n Overload — nx1 Axial overload ny1 Normal overload nz1 Lateral overload f Safety factor Vmax Maximum velocity of missile m/s VL Limit velocity M.S.
