URLIM - a Unified Radome Limitations Computer Program, Volume 1. Theoretical Background

Abstract

URLIM, a unified radome limitations computer program, has been developed to aid the radome design engineer by providing a definition of the maximum flight performance capabilities of radome materials. URLIM numerically determines the response of the radome to aerodynamic heating and loading. It computes the following as functions of trajectory time: thermal stress; radar boresight error rates; missile-radome attachment stresses caused by maneuvers, pressure, and drag forces; and the onset of radome melting. The basic output of the program is a notation of trajectory time at which the radome reaches its design limitations. Many options are available to the user of the URLIM program that provide a wide variety of analysis capability. For this reason, URLIM may also be considered as a general purpose aerodynamic heat transfer program as well as a specific purpose radome limitations program. Volume 1 of this report presents the theoretical background of the analysis techniques used in URLIM; Volume 2 provides a detailed explanation of how to use URLIM.
