The Regression Rate-Based Preliminary Engineering Design of Hybrid Rocket Combustion System

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...

Regression rate study in a small Hybrid Rocket Engine using N 2 O / paraffin propellant

1 Abstract: In the frame of the FAST20XX project under the supervision of ESA, two hybrid rocket engines are developed at Université Libre de Bruxelles (ULB) in collaboration with the Royal Military Academy of Belgium to assess the performance of paraffin/N2O propellants. The goal behind the study is to measure the regression rate and optimize the size of ALPHA, which is a sub-orbital vehicle d...

Dispersion of Toxic Exhausts from Liquid Rocket Propellant Combustion 25 Dispersion of Toxic Exhausts from Liquid Rocket Propellant Combustion

Environmental impact assessment of liquid rocket motor exhaust obtained due to mainly liquid propellant combustion have been highlighted. Exhaust product analysis has been carried out theoretically by computer software NASA CEC -71 to identify toxic emissions of rocket combustion. In the present study a high volume Air Samplers (APM-430) was deployed at predetermined locations near launch pad f...

Survival of the Interest Rate Based Debt Financing System

Evidence has been mounting (over the centuries) that the interest based debt financing regime is under ever increasing distress. All of the earlier crises whatever label they carried− exchange rate crisis or banking crisis – have been debt crises in essence. At the present, empirical research suggests that the debt-to-GDP ratio of the richest members of the G-20 threatens to touch 120% m...
