Aircraft Engineering and Aerospace Technology, 1935
THOUGH rockets have aroused a good deal of public interest during the last few years and a great number of very interesting books and articles have been published about the theoretical side of this new science, little is generally known about the experimental progress that has been made, especially in Germany and the U.S.A.

Nuclear rocket engines may be divided into two general classes based on the type of reactor used, i.e., solid-core systems and fluid-core systems. The latter may be further subdivided into liquid-, gas-, and plasma-core engines. Although fluid-core systems have been studied by a number of investigators during the past ten years, no major development ...

Nanoparticles for solid rocket propulsion
Journal of Physics: Condensed Matter, 2006The characterization of several differently sized aluminium powders, by BET (specific surface), EM (electron microscopy), XRD (x-ray diffraction), and XPS (x-ray photoelectron spectroscopy), was performed in order to evaluate their application in solid rocket propellant compositions. These aluminium powders were used in manufacturing several laboratory

Rocket Propulsion with Sparklers
The Physics Teacher, 2006A fairly well-known demonstration using a sparkler is the following: Bend the wire where you hold it at 90° to the active part, and insert it into the chuck of a drill. Darken the room, ignite the sparkler, and let the drill rotate slowly. A shower of sparks flies off tangent to the circular motion, much like sparks from a rotating whetstone.

This is basically a long write-up I made about antimatter rocket propulsion. I’m still learning, so a lot of the maths and ideas are from reading online papers and trying to understand how proton–antiproton annihilation works. I tried to model how the energy splits into pions, how a magnetic nozzle could maybe push them into a single direction, and ...

Thermodynamics and rocket propulsion
Journal of Chemical Education, 1969This paper outlines the application of the principles of chemical thermodynamics to a comparison of the merit of one rocket propellant (fuel plus oxidizer) with that of another fuel-oxidizer pair for liquid-fueled rocket motors.
