28 -- NON-RECURRING ENGINEERING AND ANALYSIS AND SUPPORT TO DETERMINE THE EFFECTS OF INTEGRATING THE NP2000 SYSTEM IN THE T56 SERIES POWERED E-2C/C2A AIRCRAFT!! POC Molly Akin, Phone (301) 757-7033; Contracting Officer, Terrence O'Connell!! E-MAIL: akinma.jfk@navair.navy.mil, akinma@navair.navy.mil. The Naval Air Systems Command intends to place an order under the terms of basic ordering agreement, N00019-95-G-0001, with Allison Engine Company for non-recurring engineering, test services and program support to facilitate the integration of the NP2000 propeller system in the E-2C/C2-A aircraft powered by Allison Model T56 engines. The engineering effort requires preliminary structural analysis to determine potential structural effect of the NP2000 system the T56 Series III and IV engines as integrated in the E-2C and C-2A aircraft. Specific investigations include fatigue loads on the prop shaft, engine carcass loads due to maneuvers, 1xP loads and hard landings and engine vibratory modes. Technical management support may include support of the NP2000 IPT, associate contractors in design review and provision of data. Allison Engine Company has a forty year investment in the design, development and manufacture of Model T56 series engines and is the only source with the T56 design, performance and engineering expertise, data, models and test capability required to perform the analysis and assess the effects of the NP2000 propeller system on engine performance characteristics and parameters.
