PROBLEMS ENCOUNTERED IN THE USE OF LIQUID OXYGEN 570170

Types of problems which are encountered by using liquid oxygen as the source of breathing oxygen are discussed; and, it is noted that today's liquid oxygen systems are workable solutions for military aircraft. The question is raised whether today's systems are the end result or simply a step in the right direction. Schematics of the typical oxygen systems are introduced, and it is concluded that the basic shortcomings of the current systems are complication and the degree of reliability. In order to stimulate thinking toward the solutions of the basic problems; methods of decreasing leakage, improving filling time, and presenting oxygen quantity in more useful terms are discussed in the light that frequent re-appraisal leads to improvement changes.
