Abstract

This short review article explores the advancement, challenges, and prospects of boron-laden solid fuel for ramjet. The energetic aspect of boron combustion is well known, but the complications associated with its efficient combustion persist and must be overcome to harness its potential completely. The strategies like coating, adding additives, and utilizing boron nanoparticles, which may improve its combustion performance, are widely studied. The latest development in advanced rocket propulsion systems, i.e., using a hybrid fuel-based gas generator for ducted rockets or air augmentation of hybrid rockets, seems a feasible idea; as it can provide two-stage combustion, which may significantly promote and improve the combustion performance of boron hence the specific impulse. Since it utilizes hybrid fuel, it retains its advantages of it as well as its drawbacks. To mitigate these drawbacks, various strategies/suggestions are briefly discussed here. A fundamental aspect of boron combustion must be fully understood and addressed for its applications in advanced propulsion systems.

冲压发动机应用含硼固体燃料的挑战和前景综述

这篇简短的综述文章探讨了冲压发动机用含硼固体燃料的进展、挑战和前景。硼燃烧的能量方面是众所周知的，但与其有效燃烧相关的复杂性仍然存在，必须加以克服才能完全利用其潜力。涂层、添加添加剂和利用硼纳米颗粒等策略可以提高其燃烧性能，这些策略被广泛研究。先进火箭推进系统的最新发展，即在管道火箭中使用混合燃料气体发生器或混合火箭的空气增强，似乎是一个可行的想法；因为它可以提供两阶段燃烧，这可以显著促进和改善硼的燃烧性能，从而提高比冲。由于它使用混合燃料，它既保留了混合燃料的优点，也保留了缺点。为了减轻这些缺点，这里简要讨论了各种策略/建议。硼燃烧在先进推进系统中的应用必须充分理解和解决硼燃烧的一个基本方面。
