The Second Generation Comprehensive Helicopter Analysis System (2GCHAS) is a comprehensive, multi-disciplinary, computer software system for predicting rotorcraft aeromechanics characteristics. It is a finite element based system with a variety of aerodynamic modeling options and provides modeling and analysis flexibility, prediction accuracy, and user-friendly input and output. The software is maintainable, expandable, and transportable to various computer platforms. The paper briefly describes the development of the System and key features for modeling complex rotorcraft. A series of rotorcraft analysis problems is presented to illustrate the range of capabilities available, including single and tandem rotor helicopters with engine/drive trains and feedback flight control systems. Various aerodynamic airloads, rotor wake, and component interference models are used in calculating performance, flight dynamic response, rotor loads and vibrations, and aeroelastic stability.
