Experimental Investigation of Corncob Charcoal as a Sustainable Carbonaceous Fuel for Composite Solid Propellants

Abstrak

This current scientific exposition rigorously investigates the foundational physicochemical traits governing solid composite propellants engineered through a direct comparative analysis bridging two distinctly unique carbonaceous materials namely the organically harvested corncob charcoal against the standardized activated carbon baseline. Deploying an uncompromisingly strict quantitative experimental framework dictates the formulation of test specimens utilizing an exact compositional ratio encompassing 75% potassium nitrate acting as the primary oxidizer fused seamlessly alongside 15% carbonaceous substance and 10% sulfur before subjecting these precise mixtures toward exhaustive empirical evaluations encompassing rigorous density measurements alongside definitive combustion velocity tracking and raw propulsive thrust quantification culminating in the exact calculation of specific impulse alongside the paramount thrust-to-weight ratio.

The subsequently retrieved empirical datasets unequivocally expose a profoundly massive characteristic divergence separating these two distinctly utilized combustible materials. The industrially standardized activated carbon framework absolutely dominates the sheer kinetic power spectrum by miraculously generating a 32.5% superior specific impulse magnitude peaking flawlessly at 79.07 seconds while simultaneously maintaining an average TWR metric standing exactly 23.5% greater than the agricultural alternative whereas the organically formulated corncob refuse conversely establishes an unshakeable supremacy regarding absolute combustion stability alongside unparalleled inter-sample consistency considering the maximum specific impulse deviation afflicting the botanical specimen reaches a minuscule 2.62 seconds thereby proving phenomenally more stable when positioned against the highly erratic industrial carbon counterpart enduring severe operational fluctuations hitting exactly 13.55 seconds. This overarching scientific breakthrough ultimately finalizes a concrete academic recommendation mandating the deployment of activated carbon constructs within advanced propulsion mechanisms desperately requiring massive kinetic surges while simultaneously designating the discarded corncob charcoal as the unequivocally ideal candidate powering ballistic rocket architectures strictly prioritizing an unwavering combustion profile devoid of excessive operational volatility.
