We have to look for safe and non - hazardous characterstics when trying to find new propellants.
<h3>What are propellants ?</h3>
Propellants are any gas, liquid, or solid the expansion of which can be used to impart motion to another substance or object.
The Desirable properties for propellant combinations are ;
- low molecular mass and high temperature of reaction products (for high exhaust velocity),
- high density (to minimize tank weight),
- low hazard factor (e.g., corrosivity and toxicity),
- low environmental impact,
- low cost.
