Development and Initial Testing of a Micro-Newton Torsion Pendulum with Gas-Dynamic Calibration
… be robust against electromagnetic interference effects internal or external to the thruster being tested. The design and testing of a gas-dynamic calibration thruster is included. This thruster is fully self-contained on the pendulum arm, with no external wires or feedlines connected to the …

Instrument development and plasma measurements on a 200-watt Hall thruster plume
… Plasma measurements consisted of studying facility and thruster effects on the plume. Facility effects included background pressure and sweep radius, while thruster effects included discharge voltage and flow rate. Experimental results showed that current density is more sensitive to …

Measurements of secondary mass flux from a surface bombarded by an [EMIM][BF4] electrospray plume
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2024-03-01 without embargo terms

Performance characterization and optimization of a diverging cusped field thruster with a calibrated counter-weighted millinewton thrust stand
… signicant, though not completely predictable, effects on thruster performance. The modes differ in plasma diffusivity and anode current. Facility effects, such as chamber back pressure and cathode coupling, on performance were also briefly y researched. In order to characterize the performance …

Fluid-structure interaction of a cantilevered plate in supersonic separated flow
… This setup allows for the study of recirculation effects and unsteady pressure forcing on the cantilevered plate in the absence of shock-boundary layer interactions that would be present if the plate were inclined to the flow. The height of the cavity has been chosen such that it corresponds to …

Measurement and Prediction of Rotor Noise Sources for sUAS in Outdoor and Laboratory Environments
… and under different operating conditions. Facility effects on performance and noise were first assessed by experimentally studying two commercially available eVTOL rotors in an enclosed anechoic environment and an open environment. For experimental measurements that were conducted in the …
