Abstract
Recent developments in the design of integrated microthrusters and thruster arrays with nanoenergetic propellants present new promising directions. The nanostructured energetic composites based on bismuth hydroxide and aluminum nanoparticles generate adequate thrust, heat, pressure, and gas flow. Nanothermites can be successfully used as solid fuel propellants in microthrusters. Low-fidelity experimental validation and characterization of fabricated 3D-printed microthrusters and thruster arrays with hydroxide nanoenergetic propellants are reported. 3D printing allows integration of compliant thruster components and functional modules. We outline further developments to guarantee robustness, stability, thermal control, and self-assembly of advanced-technology nanoenergetic materials for aerial systems, as well as advanced sensing. The reported solutions are examined and experimental results are documented.
