Abstract
A lithium-soap-thickened synthetic hydrocarbon (polyalphaolefin) grease was developed in response to failure of a sodium-soap-thickened mineral oil grease on long term storage in the F-107 engine of the Cruise Missile. The new grease was heavily fortified with performance improving additives and has demonstrated excellent results in bench tests, in an engine test and in the actual application. The superior capabilities of the grease include very high speed (30,000 rpm), high load, high temperature, low water washout, excellent corrosion inhibition and excellent wear resistance. A military specification, MIL-PRF-32014, was written to procure this grease. Testing of the grease in C-5 aircraft landing gear is currently underway and new applications are being investigated. This grease is anticipated to meet most of the military applications and is being proposed as a new multipurpose grease that could significantly reduce the number of greases in the military inventory. Presented at the 57th Annual Meeting in Houston, Texas May 19–23, 2002
