6、references, and corrects typographical errors. 1. SCOPE This SAE Aerospace Standard (AS) prescribes requirements for the various types of nozzles that are used for the refueling and defueling of aircraft fitted with pressure fuel servicing systems. It is to be used as a replacement for MIL-N-5877, M

7、S29520 and for all commercial applications. 1.1 Classification The nozzles specified herein shall be classified in accordance with Table 1. Type I nozzles are primarily used by military services; Type II nozzles are primarily used in commercial service. 1.2 Field of Application This specification is

8、 for all nozzles that are utilized either in commercial or military applications where the aircraft system utilizes pressure fuel-servicing systems. The nozzle shall be compatible with and mate with the international aircraft adapter fitting in accordance to ISO 45 Aircraft Pressure Refueling Connec

9、tions. 1.3 Nozzle Configuration The nozzle shall conform to the design interface envelope of Figure 1 of this document. The inlet configuration outside of WKHHQYHORSHLVDWWKHPDQXIDFWXUHUVRSWLRQDQGPDEHGHVLJQHGWRKDYHDQDQJOHG VWUDLJKWRUYDULDEOHFRQILJXUDWLRQWRmeet individual requirements. The envelope re

10、strictions are mandatory to assure that aircraft fuel system manufacturers and nozzle manufacturers have a common interface with which to work. This will assure compatibility between the available nozzles and the aircraft refueling system adapters. The nozzle may be configured to include various fea

11、tures and be available in various inlet configurations including, but not necessarily limited to those shown in Table 2. 2. APPLICABLE DOCUMENTS The following publications form a part of this document to the extent specified herein. The latest issue of SAE publications shall apply. The applicable is

12、sue of other publications shall be the issue in effect on the date of the purchase order. In the event of conflict between the text of this document and references cited herein, the text of this document takes precedence. Nothing in this document, however, supersedes applicable laws and regulations

13、unless a specific exemption has been obtained. SAE INTERNATIONAL AS5877B Page 2 of 25 Table 1 Nozzle classifications Type Class Description I D-1 Pressure refueling nozzle with a curved inlet with a 6-bolt flange and without a hose end control valve. Various accessories may be added to the basic noz

14、zle as noted herein. I D-1R Same as Type I, Class D-1 except a 45-psi or 55-psi hose end control valve is included as an accessory. I D-2 Same as Type I, Class D-1 except the inlet is straight. I D-2R Same as Type I, Class D-2 except a 45-psi or 55-psi hose end control valve is included as an access

15、ory. I D-3 Same as Type I, Class D-1 except a variable inlet configuration is used. The variable inlet configuration can assume either the D-1 or D-2 configuration without disassembly. I D-3R Same as Type I, Class D-3 except a 45-psi or 55-psi hose end control valve is included as an accessory. II U

16、nderwing nozzle designed primarily for commercial usage with a straight body and various inlet connections and without a hose end control valve. Various inlets and accessories may be included as noted herein. II R Same as Type II except a hose end control valve is included as an accessory. The custo

17、mer shall specify the pressure setting for the hose end control valve. III - Underwing nozzle designed primarily for commercial usage with a variable geometry body and various inlet connections, but without a hose end control valve. Various accessories may be included as noted herein. III R Same as

18、Type III except a hose end control valve is included as an accessory. The customer shall specify the pressure setting for the hose end control valve. Note: Nozzles may be fitted with on optional strainer ball valve. SAE INTERNATIONAL AS5877B Page 3 of 25 Figure 1 - Envelope requirements 3. Certain p

19、rovisions (dimensions required for connection with the adapter and envelope dimensions) of this specification are the subject of international standardization agreements ASIC AIR STD 25/4, NATO STANAG 3105, and ISO 45. When a revision of AS5877 is proposed which shall affect or violate the internati

20、onal agreements concerned, appropriate reconciliation action through international standardization channels shall be taken. 4. Nozzle poppet face shall be located at 0.475 to 0.506 inches above the Adapter Locking Lug Reference Plane (adapter is located in an underwing position with the lugs on the

21、surface away from the aircraft wing). Nozzle poppet travel shall be 1.375 min to 1.436 max inches. SAE INTERNATIONAL AS5877B Page 4 of 25 Table 2 - Various features available on nozzles Feature Size/Type Description Inlet Thread 2, 2-1/2, and 3 inches NPT or BSPP Inlet configuration may be one of ma

22、ny including, but not limited to, the ones described in this table. Inlet Flange 2-1/2 inches, 6-through bolt type flange for gasket seal “Military“ type tube connection (formerly MS33786-40) utilized on Type I, Class D-1, D-1R, D-2, D-2R, D-3 and D-3R nozzles for military applications. The inside d

23、iameter of the inlet flange shall be 2.506 inches 0.009 inches (63.73 mm). Handle Configuration Various Stick, stirrup and wheel type handles are available from different manufacturers. The manufacturer specifications should be checked before ordering. Note that handle selection may affect nozzle st

24、owage and/or interlock devices on refueling vehicles. Stick type handles are required for military applications. Strainers 40-mesh 60-mesh 100-mesh A device, normally mounted in either the inlet disconnect or ball valve, that is designed to be the last defense against and for the detection of “large

25、“ contaminants entering the aircraft fuel system. The size of strainer mesh is at the option of the buyer (see 3.3.5 for certain restrictions). Note that the degree of filtration capability is dependent upon mesh and wire size. The manufacturer specifications should be checked before ordering. Bondi

26、ng Cable Varies with manufacturer An accessory part of the unit as specified in the procurement document. A relatively short cable with either a standard phone type jack plug or an alligator clip (or both) that allows for bonding the nozzle to the aircraft structure. The manufacturer specifications

27、should be checked before ordering. The bonding of the nozzle to the aircraft, although still done in some locations is not a usual requirement. Bonding cables used on underwing nozzles for military applications are limited to Marine Corps/Army equipment only. Hose End Control Valves (Regulators) Nom

28、inal 2-1/2 inch size with connections to mate the nozzle for which it is designed Unit designed to limit nominal pressure at the outlet and to sense rapid buildup of pressure in the aircraft manifold and to control surge pressure within the aircraft system. Various pressure settings are available an

29、d must be specified in accordance with the manufacturer details. Commonly advertised spring ratings are 35, 45, 50, and 55 psig. Note that the advertised spring ratings may not produce control pressures of the same value. Manufacturers test reports should specify the actual limits. Inlet Type - furn

30、ished as an accessory of the nozzle Most will use the sizes and types noted under Inlet Thread Quick Disconnect - Mates the nozzle to the hose and allow for quick access to a strainer and for quick replacement for repair. A swivel may or may not be present in this type of inlet. Quick Disconnect Dry

31、 Break - Same as above except the hose half of the unit is self-sealing or manually sealed to keep the fuel in the hose from draining out of the system when the nozzle is disconnected. Fuel will still be present in the nozzle body and care shall be exercised to keep from spilling this fuel. Strainer

32、 Ball Valve or similar type device - A unit incorporating a ball valve or similar type device that allows for the inspection of the strainer without removing the nozzle from the system. Provides for the minimum spillage of fuel from the system. A quick disconnect and/or swivel may or may not be incl

33、uded in this unit. Swivel This feature may be an integral part of the nozzle or as an added optional feature contained in either the quick disconnect, dry break, ball valve or similar device. It is needed to ease hose handling during refueling. Vacuum Breaker An optional accessory part of the unit a

34、s specified in the procurement document. A small spring-loaded valve mounted on the side of the nozzle to allow for the incursion of atmospheric pressure to the fuel system to prevent the formation of an excessive vacuum within the system. The manufacturers specifications should be checked before or
