摘要

A Joint Aircraft Survivability Program (JASP) project was awarded in 2014 in order to accelerate the research and development on military helicopter transmission loss of lubrication survivability. This JASP project, "Helicopter Transmission Loss-of-Lubrication" was a collaboration between the US Army, US Navy, and NASA and completed in 2018. The approach for the effort was to first screen emerging technologies using coupon-level methods, then test those showing the most promise at the component level, and finally to downselect and evaluate these technologies at the system level. Several concepts to reduce heat generation, increase heat rejection, increase material tolerance to higher temperatures, and increase material resistance to damage were evaluated for this effort. Included in this evaluation were: a ceramic material for bearings, four different gear steels, various levels of gear surface roughness, six gear coatings, five lubricant and lubricant additive variations, and gearbox noble gas injection. After gear testing at the component level, isotropic superfinishing and ionic liquid lubricant additive were down selected as the two most suitable technologies for the system level testing. These technologies underwent loss of lubrication testing to failure in an intermediate gearbox from a standard configuration medium lift helicopter. A baseline loss of lubrication test, without these technologies, was also performed for comparison.
