Abstract:

This paper presents a brief review of our understanding of the mechanism of dispersion of rocket fire and in particular, shows the very high intrinsic sensitivity of rockets to various imperfections which are sometimes so minute that in practice they are not measureable. As an example of the basic problems of the design of rockets, the following crude figures may be given for a hypothetical simple rocket deflection of the rocket per unit inclination of the nozzle, 40 typical inclination of the nozzle, 1 mil factor by which it is desirable to reduce the sensitivity of such rocket to this particular imperfection, 400. All known systems of unguided rocket fire can go only a small part of the way toward such an ideal - and so so only at the cost of considerable complications of design, extreme care in manufacture, and relaxation of the standards of performance.
