Closed Loop Throttle Control of a Liquefying Fuel Hybrid Rocket Motor

Motor / Tachometer Closed - Loop Speed Control System

DSP Based Closed Loop Position Control of BLDC Motor

This paper presents the design of digital controller for a BLDC motor to control the speed and position control using Digital Signal Processor (DSP) TMS320LF 2407 which is used in an Electromechanical Actuator. Brushless D.C motor (BLDC) are one of the motor types rapidly gaining popularity. This motor offer a simple and rugged motor Solution for many variable speed drive application. Rotation ...

Visualization of Combustion Within a Hybrid Rocket Motor

A visualization facility has been developed at Stanford University in order to study flow in a turbulent combustion boundary layer. The motivation for the facility arises from recent studies of fast burning fuels for hybrid rocket propulsion where droplet lift-off from the melting fuel surface is the dominant mass transfer mechanism. The facility, shown in Figure 1, has been used to image the c...

A hybrid solution approach for a multi-objective closed-loop logistics network under uncertainty

The design of closed-loop logistics (forward and reverse logistics) has attracted growing attention with the stringent pressures of customer expectations, environmental concerns and economic factors. This paper considers a multi-product, multi-period and multi-objective closed-loop logistics network model with regard to facility expansion as a facility location–allocation problem, which more cl...

A Labscale Hybrid Rocket Motor for Instrumentation Studies

An interest in plume spectroscopy led to the development of a labscale Hybrid Rocket Facility at the University of Arkansas at Little Rock (UALR). The goal of this project was to develop a reliable, consistent rocket motor testbed for the development of plume spectroscopy instrumentation. Hybrid motor technology was selected because it has proven to be safe and inexpensive to operate. The proje...
