Description / Abstract:
This SAE Aerospace Recommended Practice (ARP) is an application
guide for hydraulic power transfer units and describes:
• The various types
• Typical design approaches
• Their operational characteristics and limitations
• Circuit recommendations
• Typical applications
The scope of this ARP is limited to devices that transfer power
between hydraulic systems and do so by means of rotary
subassemblies such as hydraulic motors and pumps.
Purpose
The purpose of this document is to apprise the system designer
of the available options in power transfer units, configuration
tradeoffs, and system design precautions in their application.
