INTRODUCTION INTRODUCTION Shell companies manufacture, and distribute throughout the world a full range of aviation products required for the operation and maintenance of aircraft of all types. This range includes:- 1.4 Aviation Turbine Fuels 07 1.5 Aviation Gasolines AeroShell Performance Additives AeroShell Turbine Engine Oils AeroShell Piston Engine Oils INTRODUCTION AeroShell Greases AeroShell Hydraulic Fluids AeroShell Fluids AeroShell Preservatives This manual contains information on the characteristics and specifications of these products and offers guidance on their application. The Specification information provided is correct as known at the time of going to press. Due to the fact that commercial and military specifications for aviation products are subject to frequent changes, it is advisable to consult the local Shell company, whose representative will also give advice on availability (not all grades are always available worldwide), prices and packaging and will be glad to answer any other queries. All reasonable care has been taken in the preparation of this publication; however, no responsibility can be accepted for the consequences of any inaccuracy which it may contain. GENERAL NOTES GENERAL NOTES ON AEROSHELL PRODUCTS The notes contained in this section apply to the complete range of AeroShell Specifications products. Additional notes specific to each product group are given in the The majority of AeroShell products are manufactured to comply with British or U.S. notes at the front of each chapter. Government Specifications because these are acceptable to most aircraft manufacturers and airline operators. In certain cases where no suitable specification exists, Shell products have 1.6 Notation 06 been developed to meet specific performance requirements. 1.7 The brand names chosen for the range of AeroShell products comprise three parts: the name ‘AeroShell’ followed by the words ‘Turbine Oil’, ‘Fluid’, ‘Grease’, etc. and finally a number Many of the British and U.S. Government Specifications (as well as those of other NATO and/or letters designating each product. The numbers do not always follow a sequence. In countries) are interchangeable, although the specifications are not identical. The words the case of turbine and piston engine oils the number relates to the oil viscosity; for greases, ‘approved’, ‘meets’, ‘equivalent’ and ‘corresponding’ have been used in the text to define GENERAL NOTES fluids and compounds the numbers merely differentiate between products and gaps occur in the relationship between products and specifications; the precise meaning of these terms is the sequence due to obsolescence. Consequently an up-to-date version of this book should as follows: always be used for reference purposes. Approved indicates that the product has been manufactured to meet the requirements of Applications the specification, and against which it has been approved (where type approval is required). GENERAL NOTES Under this heading the more important and known representative aviation uses have been named for each AeroShell Grade, and these are intended to serve as a general indicator of Meets indicates that the product complies with the requirements of the specification and, the type of application for which the grade is normally suitable. Further consultation with the either type approval is being obtained, or because the specification is now obsolete, it is not component manufacturer is recommended in case of doubt. possible to obtain type approval (where type approval is required). Whenever an aircraft is certified, all of the oils, greases and hydraulic fluids used on that Equivalent indicates that the product complies with the major requirements of the aircraft are specified for each application point on the type certificate. The Type Certificate specification but has not necessarily been manufactured to the specification. will specify, either by specification number or by specific brand names, those grades which are qualified to be used. The U.S. Federal Aviation Administration (FAA) regulations state Corresponding indicates that the product has not been manufactured to meet the that only grades qualified for specific applications can be used in certified aircraft. Therefore specification and that it is the nearest product available. it is the responsibility of the aircraft owner or designated representative to determine which grades should be used. The letters ‘DEF’, ‘DEF STAN’, ‘DTD’, ‘DED’, ‘D.Eng.R.D.’, ‘D.Eng.D’, ‘DERD’, ‘CS’, ‘TS’ and ‘BS’ refer to British Specifications; ‘MIL’ and ‘DOD’ refer to American Specifications. As an Many AeroShell products are used in non-aviation applications especially where the aid to users, details of French and Russian Specifications are included but specifications of operating requirements or properties are at the extreme for industrial lubricants (for example, other countries are not included. high or low temperatures). Details are not included in this publication but further information is available from local Shell companies. Currently major changes are taking place to both U.S. and British Specifications. The U.S. authorities have decided to eliminate MIL specifications as they are currently known and In selecting an AeroShell Grade for a non-aviation application the properties of the replace them with performance specifications. These will be labelled MIL-PRF- followed grade must be examined. This will only give an approximate indication as to the expected by a number. Many MIL-PRF- specifications have now been issued and others will follow performance in the specific application. However, such data must be regarded as guidance until all current MIL specifications have been converted. The numeric part of the MIL-PRF- only. There is no laboratory test that can give a complete prediction of performance in the designation is the same as the numeric part of the MIL specification it replaces; actual use, and the final stage in any decision must involve performance tests in either the however, the letter which denotes the Revision level has also changed. MIL actual equipment or in the laboratory/test house under conditions expected in service. specifications which are cancelled or obsolete will not be changed. A small number of MIL specifications have been converted to MIL-DTL- specifications, where DTL represents ‘detail’. GENERAL NOTES For certain products, the U.S. authorities have decided to no longer maintain military Since compatibility also depends upon the operating environment, it is impossible for specifications; in these cases, they have been converted to civil specifications by the SAE lubricant suppliers to be aware of all possibilities of use. Therefore, it is most important that (Society of Automotive Engineers). material or equipment manufacturers are consulted regarding compatibility of oils, fluids and greases with specific materials. Most elastomer manufacturers produce comprehensive 1.8 Examples of these changes include: 08 tables of compatibility of their elastomers with a large range of products and these tables 1.9 should therefore be consulted. MIL-H-5606G became MIL-PRF-5606H MIL-L-23699E became MIL-PRF-23699F Where appropriate, more information on compatibility is given at the front of each product MIL-T-83133D became MIL-DTL-83133E section in this book.
