<dd>A Graphical User Interface (Gul) was developed and implemented as the front end of the NPS software Joint Army/Navy Rotorcraft Analysis and Design (JANRAD). The original JANRAD computer program was developed to aid in the analysis of helicopter rotor performance, stability and control and rotor dynamics. An interactive program, JANRAD was capable of accurately and quickly solving helicopter design problems at the preliminary design level. The addition of the Gul greatly simplified the use of the program but added considerable complexity to the original MAThAB0 M-File code. Because of the increased complexity, only the Performance Analysis module of the program was modified. The use of several new features of MAThAB0 version 5.1, such as the GUIDE0 and Structure functions, simplified the construction of the Gul environment and enhanced the tie between the user interface and performance calculation routines. Although initiated from the MAThAB command line, the program can now be worked entirely from the "Windows'1 environment. The performance routines weremodified extensively to connect the user input with the existing analysis routines. However, the fundamental method of analysis remains unchanged. Several cases of Sikorsky UH-60A Black Hawk input data were run and results compared with those from JANRAD version 3.1(1995). The results correlated exactly. A users Guide was developed and is included in Appendix A</dd>
