The cluster was synthesized through a controlled reaction resulting in an atomically precise structure. This specific architecture provides the stability necessary for handling, addressing the common "inherent instability" of traditional hydride compounds. 2.2 Ignition Testing
The advancement of aerospace propulsion requires the development of environmentally benign, high-performance solid hypergolic fuels. While hydride-containing compounds offer superior combustion properties, their instability has historically limited their use. This paper explores the synthesis and performance of an atomically precise copper hydride cluster, Cu11H3(5N-dpf)6(OAc)2 (denoted as Cu11H3 ). When combined with high-test peroxide (HTP), the cluster achieves a remarkable ignition delay (ID) of 16 ms and a specific impulse of 254 s. This research highlights the critical role of hydride-proton interactions in accelerating the ignition process. 1. Introduction H 3.mp4
Performance was evaluated using high-test peroxide (HTP, >90% H2O2) as the oxidizer. The ignition process was documented via high-speed videography (referenced in technical documentation as Video H 3.mp4 ) to measure precise ignition delay times. 3. Results and Discussion 3.1 Hypergolic Performance The experimental data revealed that exhibits: Ignition Delay (ID): 16 ms. Specific Impulse (Isp): 254 s. 3.2 Chemical Mechanism The cluster was synthesized through a controlled reaction
