Nuts, Self-Locking, UNS N07001, 730 °C, 1100 MPa and 1210 MPa, Procurement Specification For, Metric

2018-03-18
WIP
MA1943B
This procurement specification covers aircraft quality self-locking nuts for wrenching (hex, spline) and anchor (plate, gang channel, shank) type of nuts made from a corrosion and heat resistant nickel-base alloy of the type identified under the Unified Numbering System as UNS N07001. Tension height nuts having overall length of threaded portion not less than 1.2 times the nominal thread diameter have 120 MPa minimum tensile strength at room temperature. Shear height nuts having shorter threaded portion have 1100 MPa minimum tensile strength at room temperature. Maximum test temperature of parts is 730 degrees C.

Design and Operating Requirements of the Onboard Aircraft Refueling System and Associated Ground Refueling Equipment Interface

2018-03-18
CURRENT
AS5751
This SAE Aerospace Specification (AS) is applicable to all aircraft. This AS defines the minimum design and operating requirements for the aircraft refueling interface. These requirements establish the minimum criteria for the aircraft design that provides practical standardized refueling system requirements, provides minimum standardized criteria for the operation and performance of any aircraft refueling equipment, and establishes an integrated minimum performance for aircraft refueling operations. This standardization provides the minimum design criteria to assure full compatibility between the aircraft refueling system connection point(s), aircraft operating characteristics, and the design and operation of ground based aircraft refueling equipment in all steady state and dynamic refueling and defueling conditions. The criteria that shall be used to test the operation and performance of the aircraft refueling system and equipment are also specified.
