“…With respect to fuels, Al is the most popular due to its favorable properties, such as high energy density (30.5 kJ/g), wide availability, low cost, and environmentally benign products. , In particular, Al nanoparticles (ANPs) have attracted increasing attention because of their high chemical activity in various oxidizers, such as O 2 , CO, CO 2 , and H 2 O, and thereby a high benefit to enhance propulsive performance. − In comparison, little work has been devoted to that with H 2 O 2 . The combination of Al particles in H 2 O 2 can serve as promising hybrid propellants owing to the high heat release (25.8 kJ/g) and green oxidation products (Al 2 O 3 , H 2 O, O 2 , and H 2 ). , The theoretical specific impulse of Al/H 2 O 2 bipropellant can reach 258 s, which is comparable to many conventional ammonium perchlorate composites . Notably, it was found that Al particle size (from 38 nm to 35 μm), H 2 O 2 concentration, and temperature play a significant role in the combustion behaviors of this bipropellant .…”
