Abstract

The search for "greener and less toxic" alternatives to commonly used hydrazine and hydrazine derivative fuels is urgent due to their toxicity and complex handling. In this paper, the suitability of 2-azidoethanol as a possible replacement candidate for hypergolic bipropellants is reported. The compound shows good properties, such as easy synthesis, good sensitivity values, higher density, and lower toxicity. As an eco-friendly oxidizer, high test peroxide [(HTP), 98% content] is used. Rocket specific calculations of 2-azidoethanol based on the Gordon McBride code predict a maximum specific impulse of 303 s in a HTP bipropellant system. Drop tests were performed to investigate different additives for hypergolicity and short ignition delay times. Also, the effect of the amount of additive was tested and evaluated.
