U.S. and Russian Air Force: Sealed Storage of Air Materials

The high-tech aviation materials that the Air Force mobilizes, supplies, and manages are among the most important special equipment supplies for the maintenance and repair of modern fighter aircraft. Therefore, in the process of military logistics such as storage, transportation, and supply of high-tech materials, the quality factors of sealed packaging appear to be increasingly important in the protection of high-tech aviation materials. This article focuses on the methods and applications of the storage and packaging (inner packaging) of high-tech aviation materials of the US and Russian air forces, and provides reference for the storage of aviation materials for our military.

First, the United States, the Russian air force high-tech aviation materials storage target United States, the Russian Air Force air material storage packaging packaging is the use of a unified, effective and economical method, so that aviation materials are protected. The storage and packaging of high-tech aviation materials meet the needs of the military and ensure 100% storage, transportation and reliability of use. It is scientific, safe, applicable, and economical, making the overall military efficiency and economic efficiency the best. The U.S. and Russian air forces use the ABC classification method to statistically analyze inventory materials according to their importance, value, frequency, repairability, maintainability, and structural technical properties, and determine their proportional relationship. High value, high technical content, and relatively important high-tech aviation materials occupy a considerable proportion (accounting for about 25%, but the value is about 65%) as the focus of its management, implementation by item by item High-quality, high-storage grades of specially sealed packaging (such as the US Air Force's use of the highest level of A-class storage for high-tech aviation materials) are reliably and effectively stored and supplied to meet the needs of aircraft operations and training.
Second, the United States Air Force high-tech aviation materials storage and packaging methods
The US Air Force’s requirement for sealed storage of high-tech aviation materials is: At any time in the world, at any time, and under all kinds of possible adverse environmental conditions, air materials must be in a usable state after they arrive, and usually do not appear “acceptable”. The "damage. The U.S. Air Force believes that the Air Force’s weaponry and equipment system is becoming increasingly complex and expensive, and the proportion of high-tech products is increasing, making it more difficult to seal and pack aviation materials. In the course of these products must have a high degree of reliability, therefore, sealed packaging systems for demanding, these features lead to cost specifications and requirements, rather too much in terms of safety and reliability, but also do not want to reduce the cost of the product was dangerous . Sealed packaging in the development of high-tech air material aspects of the issue acceptable risk does not exist. The above view of the US Air Force stated that in terms of sealing and packaging of high-tech aviation materials, more consideration was given to the quality and reliability of sealed packaging, and economy was placed second.
The U.S. Air Force uses two standards for the storage and packaging of aviation materials: US Federal Standard Fed. Std. No. 102b (protection, packaging, and packing grades) and U.S. military specification MIL-P116G (protection, packaging methods). Yes: Establish protection, packaging grades, and specify appropriate protection and packaging methods and standards. The U.S. military specification MIL-P116G specifies general process procedures, including cleaning, drying, coating of protective agents, and the use of encapsulation, shock-absorbing gaskets, pads, and packaging containers as required; 14 types of cleaning are also listed in the specification. The method, which can be specified in the contract or chosen by the contractor; proposes specific test methods to prove that the product has been properly cleaned, and 5 approved drying methods to remove any cleaning fluid or residual moisture; apply protective agent The method lists eight options; a more detailed protective packaging method (main packaging method and sub-method) is specified; quality assurance (quality testing and inspection) is specified. General aviation materials (simple in structure, not easily corroded and damaged) are sealed and packaged using U.S. federal standards without special requirements, because the cost can be reduced if the requirements are met. High-tech aviation materials require the use of U.S. military regulations, and the quality of sealed packaging is very stringent. Some packaging materials used for sealing and packaging of specific aviation materials are used in the contract to indicate the applicable packaging requirements in the contract (for example: circuit board device MIL- STD-726 3P / 1/1/00 / AA / AA / Y / XX / 5 / D3 / A / AG / AB TP3.)
Third, the Russian Air Force high-tech aviation material packaging method
The requirements of the Russian Air Force for the storage and packaging of aviation materials during storage and transportation are clearly stipulated in the aviation materials management documents. The storage, re-storage and disposal of aviation materials were separately regulated. Mainly includes the storage, resealing and disposal of aero-engines; storage, re-storage and disposal of spare parts; storage, resealing, treatment and technical maintenance of aviation ordnance equipment; aircraft aviation equipment, radio electronic equipment, communication equipment, radio flight protection Storage, resealing and disposal of equipment and testing instruments; storage, resealing and disposal of airport flight support equipment; custody and maintenance of parachute equipment; storage, resealing and disposal of aviation repair plant equipment; storage and resealing of metal materials And processing and so on. These are collectively referred to military technology and equipment storage (sequestration KOHCEPAB ЦИЯ), namely: comprehensive technical measures of military technology and equipment in long-term storage or transport taken in order to prevent corrosion. 
The basic methods of storage include: sequestration using lubricating oil; use of atmospheric anti-corrosion inhibitors; use of polymeric materials to inhibit the storage of layers; dry air storage; Examples of short-term (temporary) protection measures for black and non-ferrous metals and their products include the use of oil seal oil to prevent rust, use of working oil to prevent rust, use of oil seal grease to prevent rust, and the use of removable anti-corrosion polymeric coatings to prevent rust; Use washable anti-corrosion coating to prevent rust; use anti-corrosion polymeric coating that cannot be removed to prevent rust; use air static drying method to prevent rust; use contact anti-corrosion agent to prevent rust; use gas phase inhibitor to prevent rust; use inertness Gas rust prevention. The basic basis is: the surface of the product is isolated from the external medium and the process that causes the change in the technical state of the product is blocked. For the main sealed packaging components such as unpacking, unsealing, cleaning, drying, applying protective agent, packaging, etc., according to different requirements of aviation materials, using appropriate methods and processes. There are special provisions for the storage materials used for aviation materials, such as oil storage materials and packaging materials used for storage of aviation materials, which mainly use the materials specified in the TOCT series standards (eg: HГ-203 oil seal oil TOCT12328-77, polyethylene film TOCT10354-73 , anti-corrosion packaging paper TOCT16295-77, etc.). The author conducted an investigation on the storage and packaging of Russia's SU-27 and SU-30 aviation materials imported by the Air Force. The high-tech aviation materials used are all primary packaging. According to the nature, structure, and functional requirements of the aviation materials, corresponding special applications are used. Sealed packaging technology and comprehensive sealed packaging methods, such as internal storage, external storage, hygroscopic agent, sealing, gasketing, fixing, and packing, etc., have been applied to high-precision aeroengine fuel pumps and hydraulic pumps of hydraulic systems.
Concluding remarks: The Air Force aviation materials system should learn from the foreign military, especially the storage and packaging methods of American and Russian air force aviation materials, combined with the experience of air force aviation material storage and packaging, actively engage in research, testing, practice and application of high-tech aviation material storage and packaging. , Including studying the dynamics, development trends, packaging management systems and management methods of sealed packaging at home and abroad; researching new sealing packaging materials and applications, trial-producing new sealed packaging containers, improving sealing and packaging technology, and improving the effect of sealed packaging; researching sealed packaging Containers and machinery to realize modern packaging; research packaging specifications, quality, series, and formulation of packaging standards to achieve standardization, serialization, and generalization; and under the premise of ensuring military benefits, strive to improve the economic efficiency of sealed packaging and the efficiency of sealed packaging; The basic theory of packaging and talent development, training and education, improve the theoretical level and professional quality.
