Flexure Testing of Hydraulic Tubing Joints and Fittings

2018-12-17
WIP
ARP1185C
This SAE Recommended Practice (ARP) establishes flexure test procedures to determine and classify the fatigue strengths of reconnectable or permanent hydraulic tube joints. The procedure is intended for conducting flexure tests of fittings and joints for hydraulic tubing materials such as AMS 5561 (21Cr-6Ni-9Mn) steel or AMS 4944 (3AL-2.5V) titanium. A mean stress is applied by holding system pressure in the specimens and flexing in a rotary or planar bending test machine.

Prestressing (Autofrettaging) of Hydraulic Tubing Lines

WIP
AIR1379B
This AIR is intended to describe and document a process presently in use for proof testing, which at the same time improves the fatigue life of 304 1.8 hard CRES and 3A1-2.5V CWSR titanium hydraulic tubing lines. Aerospace Information Report (AIR) 1419 "Inlet Total Pressure Distortion Considerations for Gas Turbine Engines" documents engineering information for use as reference material and for guidance. Inlet total-pressure distortion and other forms of flow distortion that can influence inlet/engine compatibility require examination to establish their effect on engine stability and performance. This report centers on inlet-generated total-pressure distortion measured at the Aerodynamic Interface Plane (AIP), not because this is necessarily the sole concern, but because it has been given sufficient attention in the aircraft and engine communities to produce generally accepted engineering practices for dealing with it.

Fiber Optic Sensor Specification Guidelines for Aerospace Applications

2018-12-17
CURRENT
ARP6366
ARP6366 defines a comprehensive and widely-accepted set of specification guidelines to be considered by those seeking to use or design fiber optic sensors for aerospace applications. Some of the most common applications for fiber optic sensing within aerospace include inertial guidance and navigation (gyros) and structural monitoring (temperature, strain, and vibration sensing). Common sensor infrastructure elements include: transmitting and receiving opto-electronics (e.g., sources and receivers); multiplexing and demultiplexing optics; optical cabling; and signal processing (both hardware and firmware/software).

Inserts, Screw Thread, Helical Coil 19Cr-9.2Ni, Corrosion Resistant Steel, Procurement Specification For

2018-12-13
WIP
AS7245B

This specification covers closely-wound helical coil, screw thread inserts made of a corrosion resistant steel formed wire with a chemical composition in accordance with Table 1 and identified under the Unified Numbering System as UNS S30200 or UNS S30400 that can be formed by an insert manufacturer to achieve the requirements of this procurement specification. The inner surface of the insert coil, after assembly into a screw thread tapped hole, provides internal threads of standard 60° Unified form.

Bolts, Screws and Studs - Screw Thread Requirements

2018-12-13
WIP
AS3062D

This standard establishes the rolled thread element tolerances for lead, half-angle, taper, and out-of-roundness for studs used in aerospace construction; it also establishes the requirements for lead threads and runout threads for these studs.

This standard defines the requirements for runout threads and lead threads for bolt and screw rolled threads used in aerospace construction; it also specifies a referee method, by optical projection, for establishing conformity with these requirements which agree with ISO 3353.

The bolt and screw lead and runout thread requirements are also applicable to other externally threaded products where the threads are produced by rolling.
