Low-Cost Thermal Inkjet Thrusters for CubeSat Attitude Control

This project investigates the feasibility of using COTS thermal inkjet cartridges as micro thrusters for attitude control in CubeSats. With limited options available for CubeSat stability and maneuvering, this innovative approach aims to provide an affordable, low-mass solution with minimal thrust increments, ideal for small satellites. The research will focus on both analytical and experimental evaluations of the technology over a year, comparing performance against traditional reaction wheels, to fulfill the CubeSat community's need for efficient thrust in the micro-Newton range.

  1. Thermal Inkjet based attitude control TIJCube: low cost, COTS Thermal Inkjet Heads as attitude control thrusters for CUBEsat class satellites OBJECTIVE • The project will investigate and demonstrate the feasibility of a micro thruster for attitude control of cubesats based on COTS ink-jet cartridges with and without post acceleration for positional maneuvering including distributed telescopes. DESCRIPTION • There are few options for attitude control of cubesats. This project aims to provide a low cost, low mass, low incremental thrust option ideally suited for cubesat, The work will be in proving the concept analytically and experimentally. EXPECTED PERFORMANCE • Analysis and Ideation 3 months ARO • Experimental evaluation of COTS TIJs 6 months ARO • Evaluation of Improvements in TIJs 12 months ARO COMPARISON TO THE STATE OF THE ART • The only recommended cubesat attitude control component is a reaction wheel rated at 2 ft-lbs. This is too large for a cubesat. The Cubesat community needs a microthruster at the 10s-100s of micro-Newton range. COTS TIJ + post accelerator as in a colliodal thruster or a FEEP can provide the correct level of thrust. USC: INFORMATION SCIENCES INSTITUTE Project Schedule Characterize COTS TIJS Full experimental evaluation of COTS TIJs Design and construct post accelerators for TIJS Measure and calibrate TIJs with accelerators plus Final report Months 3 6 9 12 ATTACHMENT 2: Quad Summary Chart Format BAA NRO 000-08-R-9999
