ESP (External-Stores Program) - A Pilot Computer Program for Determining Flutter-Critical External-Store Configurations. Volume 2. Final Report on Program Enhancement and Delivery,
Abstract
A pilot computer program for determining flutter-critical external-store configurations, which was partially developed under two previous Naval Air Systems Command contracts, has been further enhanced and made operational on the Central Computer System at the Naval Air Development Center. The enhancements were introduced to: (1) Increase the applicability of the program to modern attack aircraft with thinner, more flexible wings, and (2) Permit the utilization of aircraft dynamics-model data from both the COSMIC and the MacNeal-Schwendler Corporation versions of NASTRAN, and also from card-image files. Additional modifications, including a substantial reduction in computer core requirements, were made to convert the original IBM code to a CDC version compatible with the computing facility at NADC. Also, logic was added to by-pass data required for store-search runs if only a conventional flutter analysis is desired. Finally, a user's manual was prepared (Volume I of this report), which, in conjunction with a FASTOP user's manual and previous theoretical documentation of the store-search procedure, should permit a practicing flutter analyst to use the new External-Stores Program (ESP) effectively.
