Research paper, 23-rd international symposium on ballistics, Tarragona, Spain 16-20 April 2007, - 8 p.In last years happens that some type of aircrafts are no more in use from different reasons, but the stocks of ammunition for them are enormous. In some cases the question of possibilities of launching aircraft rockets from ground arises. Commonly, for ground launching of aircraft rockets the need appears for increase of initial launching velocity in order to provide required rocket range and precision. In this paper different interior ballistic possibilities are studied as candidates for appropriate launching. Interior ballistic concepts of open-aft launcher, close-aft launcher, close-aft launcher with additional charge, open-aft launcher with additional charge and countermass and launcher with nozzle and additional propellant charge are analyzed. Appropriate mathematical models and computer codes are developed. Results for 57mm aircraft rocket show possibilities of different interior ballistic concepts to fulfill specified requirements.Content:
