The Embry-Riddle Future Space Explorers and Developers Society (ERFSEDS) is conducting research in developing the design for an experimental solid fueled ducted rocket. The primary objective of this research is to study the effects of thrust augmentation from installing a duct or a shroud around the back of a solid propellant rocket. Thrust augmentation is the process in which the combination of a primary exhaust jet and an entrained secondary flow in a chamber provide a higher thrust and specific impulse than the rocket firing in isolation. This presentation discusses the work of members of ERFSEDS to design and build a vehicle to test the ducted rocket concept, and the specific impulse and thrust results from multiple flights to study the effects of thrust augmentation. The end goal of this research is to publish findings in hopes of encouraging the design of more efficient rockets that are powered by solid propellant.
