摘要

Ammonium dinitramide/glycidyl azide polymer (ADN/GAP) composite propellants with or without metallic fuels are most likely candidates for a green alternative to ammonium perchlorate/hydroxyl-terminated polybutadiene (AP/HTPB) formulations. These ingredients are not only interesting in terms of environmental friendliness but also to overcome the intrinsic performance limitations of AP/HTPB. This paper describes some properties and the burning behavior of ADN/GAP-based propellants, as a function of ADN particles sizes and metallic fuel (Al, AlH₃), regarding burning rate, pressure exponent, flame temperatures, particle temperatures, and agglomeration phenomena. Furthermore, aging properties and the formation of pores during sample preparation are discussed. A small-scale motor test of an ADN/GAP/Al propellant demonstrates the basic applicability of ADN/GAP-based formulations.
