This handbook is for guidance only. This handbook cannot be sited

3、 as a requirement. If it is,the contractor does not have to comply.3. The high reliability required of all launch and space equipment is achieved by the designs,design margins, and by the manufacturing process controls imposed at each and every level ofassembly. The design and design margins should

4、assure that the equipment is capable of performing inthe launch and space environment. The manufacturing process controls are intended to assure that aknown quality product is manufactured to meet the design requirements and that any changes requiredcan be made based on a known baseline. Attention t

5、o every detail is required throughoutdevelopment, manufacture, qualification, transportation, and preflight testing to assure successfuloperations of the launch and space equipment4. For high-priority, long-life, complex spac e equipment, high reliability is usually achieved bystrict compliance to t

6、he requirements and good practices that have historically resulted in successfulmissions. Programs for these types of space equipment are generally structured to provide extensivechecks and balances, with detailed reviews of each step by independent personnel, to assure that noproblem is overlooked.

7、 Particular attention is given in the design to eliminating single-point failuremodes, wherever practicable. Special design analysis, special screening during manufacturing, andother quality provisions that will assure reliability, are implemented on any remaining single-pointfailure items to avoid

8、latent defects. For these programs, a full qualification program is conducted oneach level of assembly ranging from units, subsystems , space experiments, and on to each spacevehicle involved. 5. Not all space equipment is high priority or long life. Many space programs are for a singlemission that

9、is of short duration, and the equipment may be relatively simple, or involve only oneexperiment. Expendable launch vehicles represent another program class where the mission duration isshort, but weight constraints may eliminate redundancy. Regardless of the variations among launchand space programs

10、, there is always a requirement for high reliability, because a flight failure is nevercost effective. At the same time there is a constant drive to reduce the life cycle cost. Testing is aprimary target for cost reduction because testing costs typically represent a high percentage of thetotal progr

11、am cost. The real problem is to identify those cost-saving measures that are reasonable foreach program and that will not increase risks in an unacceptable way. Although an in-flight failure canidentify deficiencies in the test program used, mission success does not prove that the test programwas op

12、timum, cost effective, or even adequate. Nevertheless, mission success will typically be used tosuggest that the testing conducted was excessive and should be reduced in the future. Even if theextent of testing was reasonable and justified, it will often be suggested that the costs were excessive!6.

13、 This handbook, MIL-HDBK-340A, has been prepared to provide baseline test programs forlaunch and space vehicle equipment. The handbook is organized into two volumes. Volume IProvided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-HDBK-340A, Vol. Iiiipres

14、ents a test baseline for high priority space and launch vehicles. The Volume I material previouslywas included in MIL-STD-1540C. For the convenience of contractors, the same weighting factors(3.5.12) have been retained to indicate the relative importance of the baseline requirements. Changingthe wei

15、ghting factor names to provide a softer guidance tone was rejected in the interest of thosecontractors who may want to extract sections of the baseline requirements for their own applications. Volume II of the handbook documents additional facets of information pertinent to the test baselinespresent

16、ed in Volume I and how the baseline requirements can be tailored for specific programs. Thebaselines in this handbook are intended to be used as guidance or as the starting point in developing atest program for a particular program. It should be emphasized that the information included is forgeneral

17、 guidance and should not be followed if it does not accommodate the needs of a particularprogram.7.
