| Abstract: | This paper presents the principle of relaxing static stability(RSS) on aircraft firstly,and then calculates the flight performance and structure weight profits from RSS on a given transport airplane.Effects of RSS on the dynamic response character are also analyzed.The stability is worse,so it is necessary to design a control system to ensure the stability of the closedloop system.The method and results can be used in designing a relaxed-staticstability civil airplane. |
