Aerospace – System Integration Factors That Affect Hydraulic Pump Life

Published by: 2017-02-13 / 2017-02-13

This SAE Aerospace Information Report presents the following factors that affect hydraulic pump life and performance:

a. The need to supply hydraulic fluid at the correct pressure and quality to the pump inlet port

b. Considerations for the pump output

c. Factors to be considered for the pump case drain lines

d. The mounting of the hydraulic pump

e. Hydraulic fluid properties, including cleanliness

Ice Melting Test Method for Runways and Taxiways Deicing/Anti-icing Chemicals

Published by: 2017-02-21 / 2017-02-21

This test method provides stakeholders (runway deicing chemical manufacturers, users, regulators, and airport authorities) with relative ice melting capacity of runway deicing chemicals, by measuring the amount of ice melted as a function of time. Such runway deicing chemicals are often also used on taxiways and other paved areas.

This test method does not quantitatively measure the theoretical or extended time ice melting capability of ready-to-use runway deicing/anti-icing chemicals in liquid or solid form.

Aerospace Hydraulics and Actuation Lessons Learned (Stabilized: Feb 2017)

Published by: 2017-02-09 / 2017-02-09

This SAE Aerospace Information Report (AIR) contains Lessons Learned from aerospace actuation, control and fluid power systems technologies. The lessons were prepared by engineers from the aerospace industry and government services as part of SAE Committee A-6, Aerospace Fluid Power, Actuation, and Control Technologies, and were presented to the A-6 during meetings held from 1989 through 1999. The document is organized into five sections covering systems, actuation, hydromechanical components, electrical components and miscellaneous, each further divided into subsections. The lessons are presented in a concise format of Problem, Issue, Solution and Lesson Learned, often with accompanying descriptive diagrams and illustrations for clarity and understanding.

Because of the potential growth in the size of the document as new lessons are published, those presented to the A-6 Committee in 2000 and later years are planned to be released in separate slash number documents, AIR4543/1, AIR4543/2 and so on.

Unmanned Systems (UxS) Control Segment (UCS) Architecture: Data Distribution Service (DDS)

Published by: 2016-12-20 / 2016-12-20

This platform specific Interface Control Document (ICD) provides an example mapping to the Object Management Group’s (OMG) Data Distribution Service (DDS) infrastructure middleware. The mapping is based on the Unmanned Systems (UxS) Control Segment (UCS) Architecture: Model, AS6518. A series of non-normative implementation choices have been made that are specific to this ICD. These implementation choices may not be appropriate for different system implementations. The machine readable ICD and result of this mapping and implementation choices are provided with AIR6521.

Use and understanding of this document assumes a working knowledge of the UCS Architecture, the model structure and its contents.

UxS Control Segment (UCS) Architecture: UCTRACE

Published by: 2016-12-20 / 2016-12-20

The Use Case Trace (UCTRACE) is SAE publication AIR6519 of the Department of Defense Unmanned Control Segment (UCS) Architecture. This document is the SAE publication of the Department of Defense UAS Control Segment (UCS) Architecture: Use Case Trace (UCTRACE) Version 3.4(PR) approved for Distribution A public release 15.S-1859.

This information is produced from a script run against the System Use Case Model contained in the UCS Architecture Model AS6518-MODEL.eap configuration item.

The System Use Case Model includes, at its lowest level of elaboration, use cases Level 2/3 (L2/L3) that describe specific scenarios of message exchanges between Actors and internal system Participants via ServiceInterfaces.

These message exchanges provide a way to create detailed traces that answer the question: “What UCS service interfaces must my components implement to satisfy functional requirements represented by a given Level 2/3 UCS use case?”

The AIR6519-UCTRACE spreadsheet contains trace information derived directly from the message sequences in the L2/L3 use cases.

Unmanned Systems (UxS) Control Segment (UCS) Architecture: RSA Version of UCS ICD Model

Published by: 2016-12-20 / 2016-12-20

This User Guide describes the content of the Rational Software Architect (RSA) version of the UCS Architectural Model and how to use this model within the RSA modeling tool environment.

The purpose of the RSA version of the UCS Architectural Interface ICD model is to provide a model for Rational Software Architect (RSA) users, derived from the Enterprise Architect (EA) ICD model (AIR6515).

The AIR6515 EA Model, and by derivation, the AIR6516 RSA Model, have been validated to contain the same content as the AS6518 model for:

– all UCS ICD interfaces

– all UCS ICD messages

– all UCS ICD data directly or indirectly referenced by ICD messages and interfaces

– the Domain Participant, Information, Service and Non Functional Properties Models
