This SAE Aerospace Information Report (AIR) presents a glossary of terms commonly utilized in the ground delivery of fuel to an aircraft and some terms relating to the aircraft being refueled. The purpose of this document is to provide background material for educational purposes to persons designing, building, and using aircraft ground refueling delivery systems.

This AIR provides descriptions of aircraft actuation system failure-detection methods. The methods are those used for ground and in-flight detection of failures in electrohydraulic actuation systems for primary flight control. The AIR concentrates on full Fly-By-Wire (FBW) flight control actuation though it includes one augmented-control system. The background to the subject is discussed in terms of the impact that factors such as the system architecture have on the detection methods chosen for the flight control system. The types of failure covered by each monitoring technique are listed and discussed in general. The way in which these techniques have evolved is illustrated with a historical review of the methods adopted for a series of aircraft, arranged approximately in design chronological order.

in this AIR should be considered, as opposed to long-life operation and environmental requirements of a manned aircraft, engine-driven pump. Appendix A is intended to indicate typical environments for several different types of missiles. The actual requirements for a given system should be used and specified in the detailed specification.Missile pumps are categorized by a moderate testing life and a relatively short operational service life. Generally, the pumps are operated at higher speeds, temperatures, and pressures than those used in manned aircraft systems, yet reliability must be extremely high, since there rarely is a redundant system aboard the missile. Due to the short but critical life and performance requirements, development, reliability and acceptance testing should be focussed on eliminating infant mortality failures. Missile pumps must be compatible with very severe environmental conditions during the service life.

This SAE Aerospace Information Report (AIR) examines the need for and the application of a power train usage metric that can be used to more accurately determine the TBO for helicopter transmissions. It provides a formula for the translation of the recorded torque history into mechanical usage. It provides examples of this process and recommends a way forward. This document of the SAE HM-1 IVHM Committee is not intended as a legal document and does not provide detailed implementation steps, but does address general implementation concerns and potential benefits.

Metric (SI and CGS) and English units related to aerospace hydraulics are summarized. Conversion of units is provided as required. Fundamental fluid properties and physical laws governing fluid motion, pressure and other significant aspects are described in SI metric units. Examples of application to typical aerospace hydraulic system components are demonstrated.
Full throttle for engine solutions Powering aircraft from Mach 2 fighters to tiny hovering UAVs, military engine technology is now operating on a very broad front. Design and production flexibility together with reduced in-service costs are priorities. To the breaking point Test engineers use new rigs and data-acquisition equipment on the latest generation of pneumatics, engines, and airframes. PCs move into the cockpit Pilot training is getting a bit less expensive with the introduction of more portable flight simulations.
Low-altitude wind shear Researchers investigate the influences of low-altitude wind shear on takeoff, landing, and other low-level flight. Prepare for launch Lockheed Martin and its suppliers are gearing up activities to launch the first Atlas V launch vehicle before the end of the year. Modeling aircraft hydraulic systems Honeywell Normalair Garrett Ltd. and Flowmaster Inc. have developed a new approach to managing the complex and varied tasks required for the simulation of aircraft systems.
