When SMART rejections help.It's inevitable that some suggestions for equipment improvement will be turned down in the SMART program. Sometimes those rejections recognize the soldier has correctly identified a problem but that another solution has already been adopted. An example is the grease grease, mixture of lubricant and thickener. It is used to reduce friction between surfaces from which oils would leak away or cause damage by dripping, or where lubrication must be assured for extended periods. Many greases are mixtures of mineral oil and soap. seal, NSN NSN National Stock Number NSN Nokia Siemens Networks NSN National Storytelling Network NSN NATO Stock Number NSN New Substances Notification (CEPA) NSN National Student Number (NZ) NSN Never Say Never 5330-00-849-4366, for the CH-47, shown in Fig 182-2, TM 55-1520-240-23-P. A soldier noted in his suggestion that the grease seal comes as a single piece. The seal is removed every 100 hours in order to inspect the swash plate (Mach.) a revolving circular plate, set obliquely on its shaft, and acting as a cam to give a reciprocating motion to a rod in a direction parallel to the shaft. See also: Swash bearings. Unfortunately, the seal can be damaged during removal. Replacement requires removal of blades, rotor head Noun 1. rotor head - the axis around which the major rotor of a helicopter turns rotor shaft axis of rotation, axis - the center around which something rotates and ram shield. The soldier's solution was to cut the replacement grease seal in Verb 1. seal in - close with or as if with a tight seal; "This vacuum pack locks in the flavor!" lock in confine - prevent from leaving or from being removed half. The two equal parts could be installed with less effort at the unit. The SMART program evaluated and rejected the idea because the problem had already been addressed by Research, Development & Engineering Command (RDECOM RDECOM Research Development and Engineering Command (US Army, Aberdeen Proving Ground, MD) ) personnel. They have been developing a procedure for removing the one-piece swash plate grease seal since 2004. The RDECOM solution allows the cutting of the grease seal in one place. A special tool has already been designed to allow the proper cut to be made and to ensure that each seal modified is modified in the same manner. Flight testing of this modified grease seal win begin this year. However, the modified seal is a temporary fix. Past problems associated with both the forward and aft swash plate are driving development of new swash plates. The new swash plates will use a three-piece grease seal. So, while the soldier's suggestion wasn't implemented, he was nonetheless informed about both an interim and a final fix.
