Liquid Fueled Rockets

Article: Building A Better Rocket Engine
Date: Oct 14.
Although not very current, today is the 18th, I thought it would be worthwhile to know what the infamous NASA scientists are really doing with their hard earned money (going back to one of our class discussions from our science section).
Anyway, the skinny is that engineers have found a new way to improve the perfromance of "liquid fueled rockets." This was accomplished by changing the "plumbing" of the rocket to "preburn" fuel to create hot gas that helps to fuel the rocket. The goal of this project, said someone named Genge, was to create "better fuel effecientcy and higher thrust-to weight ratio, and improved reliability all at a lower cost."
Despite the high hopes for these newly fueled rockets, the goal right now is to just get something called the "alternate flow pattern" operating.
