Abstract
  • The High Altitude Liquid Engine (HALE) team is developing of a 2000 lbf thrust liquid propellant engine for a flight vehicle capable of breaching the Karman Line (100 km in altitude). As part the development of this flight vehicle, this research focuses on the design and characterization of a novel electric actuation system for the main valves of an engine using electric fuel pumps. The design uses a sliding linkage to simultaneously actuate the main valves with a DC motor powering a ball screw. This thesis documents the design of the system, including predictive models for actuation time and thermal performance. Through bench testing, the system opening time, approximate power consumption, and thermal performance under cryogenic conditions were analyzed and compared against the predictive models. This proof of concept design and the data collected on its performance provide a solid groundwork for future iterations and the potential implementation of this design into a space-shot flight vehicle.
