Description / Abstract:
The Engineering Analysis SYstem (EASY) computer program is
summarized in this report. It provides techniques for analysis of
steady-state and dynamic (transient) environmental control system
(ECS) performance, control system stability, and for synthesis of
optimal ECS.
General uses of a transient analysis computer program for ECS
design and development, and general features of EASY relative to
these uses, are presented. This report summarizes the nine analysis
options of EASY, EASY program organization for analyzing ECS, data
input to the program and resulting data output, and a discussion of
EASY limitations.
Appendices provide general definitions for dynamic analysis, and
samples of input and output for EASY.
Purpose:
A generalized computer program for determining transient
thermodynamic performance of aircraft ECS, and methods for dynamic
analysis of aircraft ECS are discussed in this report.
