Title:The Effect of Installation Power Losses on the Overall Performance of a Helicopter
Issuing Committee:S-12 Helicopter Powerplant Committee
Scope:The purpose of this SAE Aerospace Information Report (AIR) is to illustrate the effect of installation power losses on the performance of a helicopter. Installation power losses result from a variety of sources, some associated directly with the basic engine installation, and some coming from the installation of specific items of aircraft mission specific equipment. Close attention must be paid to the accurate measurement of these losses so that the correct aircraft performance is calculated.
Product Code:SAE J2362
Title:Lubricating Oil, Automotive Engine, API Service SM for Military Administrative Service
Issuing Committee:Fuels And Lubricants Tc 1 Engine Lubrication
Scope:This SAE Standard describes lubricating oils meeting the physical, chemical, and performance requirements of the American Petroluem Institute (API) SM category and the International Lubricant Standardization and Approval Committee (ILSAC) GF-4 standard. These oils are suitable for the lubrication of spark-ignition engines (gasoline engines). This document supersedes the military驴s Commercial Item Description (CID) A-A-52039.
