SOME APPLICATIONS OF WIND TO UNGUIDED ROCKET IMPACT PREDICTIONS,

Abstract

The report discusses the maximum layer thickness to be used in a real-time system where the maximization results in the minimization of digital computer core storage usage but delivers the desired accuracy. Results show that small layers, on the order of the size of the rocket, need to be used in the first portion of the wind profile but can expand to quite large thicknesses at the top of the profile. The effect of winds encountered by an unguided rocket on the re-entry leg of its trajectory and the effect of winds above 100 thousand feet are discussed. Results show that winds on re-entry are never needed above 100,000 feet and only rarely below. Winds above 100,000 feet should be used if the burnout altitude of the rocket is above 100,000 feet.
