This SAE Aerospace Standard (AS) prescribes requirements for the various types of nozzles that are used for refueling of aircraft fitted with pressure fuel servicing systems. It is to be used as a replacement for MIL-N-5877, MS29520 and for all commercial applications.Classification: The nozzles specified herein shall be classified in accordance with Table 1. Type I nozzles are primarily used by the US military services; Type II nozzles are primarily used in commercial service.Field of Application: This specification is 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 Connections.Nozzle Configuration: The nozzle shall conform to the design interface envelope of Figure 1 of this document. The inlet configuration outside of the envelope is at the manufacturer’s option and may be designed to have an angled, straight or variable configuration to meet individual requirements. The envelope restrictions 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 features and be available in various inlet configurations including, but not necessarily limited to those shown in Table 2.
