Jörg Freiling,Holger Nieswandtube closed at its ends by diaphragms, the ram accelerator, has generated considerable interest over the last years in different countries: especially in the United States, Israel, Japan, Prance and others. In Prance, the ISL performed, among others, experiments in a 30-mm-caliber ram accelerator, camilligram 发表于 2025-3-25 20:11:57
By shock compression, i. e., by the bow wave and its reflections at the tube wall, the gas mixture is heated progressively so that it becomes ignited in subdetonative combustion mode at the body’s back and in superdetonative mode, investigated mainly in the RAMAC 30 of ISL, in the slit between theGlycogen 发表于 2025-3-26 02:54:51
