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.
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.
This SAE Aerospace Recommended Practice (ARP) lists wrenching surface sizes and tolerances for fluid fittings which utilize machined or unmachined hex bar dimensions and machined or forged wrenching surfaces across the center body section of shape fittings.
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).
This SAE aerospace recommended practice (ARP) covers the requirements for external ground power equipment supplying 115/200 V, three-phase, 400 HZ output power measured at the aircraft receptacle. All forms of 400 Hz ground power including mobile and fixed systems are addressed by this document.
Identify the phase of flights that can take benefit of Aided Visual Flight for the various missions of helicopters both VFR and IFR such as: Commercial Air Transport Operations offshore and onshore, EMS (Air ambulance), Law enforcement (Operations with Specific Approvals),Search and Rescue (SAR) operations both in Maritime and Mountainous operations The Aided Flight should be considered with various levels of on-boarded sensor technology and its performance such as, but not limited to: NVG, Addition of Axial IR Sensor (with minimum performance to define), Potential use of orientable search light (night VFR) and other situation awareness means like HTAWS, SVS, and sensor like Radio Altimeter including the display mean head-down or head worn that influence operational aspects.
