LOKI WIND CORRECTION COMPUTER AND WIND STUDIES FOR LOKI

Abstract

The effect of an arbitrary wind distribution on the LOKI trajectory during boost was determined by an impulse response method; a function was derived which relates burnout deviation of flight path with the distributed wind along the boost trajectory. The wind influence function was applied to arbitrary and observed wind distributions to establish the basis for a practical field wind measuring system to transmit information to a computer which could perform an aiming correction. Results indicated the feasibility of a correction method based on a linear relationship between burnout deviation and wind, suitably measured, at a limited number of fixed stations. Wind data were gathered in the Mojave Desert and at White Sands Proving Ground by use of a balloon-borne hot wire anemometer system. An anemometer capable of fast response was designed to provide orthogonal wind components in terms of electrical outputs. A complete wind correction computer system based on the influence function and the results of wind studies was designed.
