Evaluation of on-board hydrogen storage methods for hypersonic vehicles [PDF]

open access: yes
Hydrogen is the foremost candidate as a fuel for use in high speed transport. Since any aircraft moving at hypersonic speeds must have a very slender body, means of decreasing the storage volume requirements below that for liquid hydrogen are needed. The

Effect of Correlation on Multi-Engine Rocket Propulsion Systems [PDF]

open access: yes
A matter of great concern in the design and operation of multi-engine rocket propulsion systems is the effect of the premature shutdown of one engine on the vehicle.

High-Vacuum Condenser Design: Experimental Effects from Cesium and Mercury Ion Beams [PDF]

open access: yes
Effects of variable-energy electrostatic rocket-engine ion exhaust beams that pertain to the design of high-vacuum condensers are discussed. Three ion-engine beam sources, using cesium and mercury as propellants, were operated at energy levels of 200 to ...
