Improved Recovery Vehicle (IRV) M88A1E1 Hydraulic System Analysis.

Abstract

Current M88A1E1 recovery vehicles do not have the required winch, hoist, and tow capabilities to support M1 tank equipped units. M88A1E1 prototypes to meet this requirement, were found to have serious performance deficiencies during Technical Feasibility Testing (TFT). This report document 1990-91 APG Summer Testing (ST) which resolved those deficiencies. Failure reports developed during TFT were the source upon which a ST plan was developed. Main winch pull capability, hoist block and tackle, and hydraulic system overheating were critical short comings identified in TFT and resolved during ST. The ST has identified that a hydraulic oil cooler must be installed to meet the requirements of the IRV purchase description. An assessment is presented which describes typical heat gain characteristics, of the M88A1E1 hydraulic system, during vehicle operation. Actual versus theoretical data has been evaluated and used as the basis for sizing and specifying a representative oil cooler.
