NTROL, BOMB RELEASE POINT, FORTRAN, FORTRAN 4 PROGRAMMING LANGUAGE, CONTROL THEORY. The concern in the work reported is the development of a dynamic precision weapon delivery system model for analyzing the effects of system parameters and disturbances on delivery performance. In addition, a methodology of precision weapon delivery flight control design is developed, without considering the pilot as a control element. The aircraft model accommodates a wide variety of airframe nonlinear dynamics, control points and methods and measurement systems. The bomb model is general enough for a variety of dive-bomb angles, release altitudes and release speeds. The circular error probable (CEP) at impact is chosen as a measure of weapon delivery performance, and a technique is developed for relating the effects of flight control parameters, airframe dynamics, measurement errors and gust disturbances to this measure by using the system model. Demonstration analysis is performed to show how to identify critical system parameters with regard to the delivery of an iron bomb and to illustrate how the method of analysis can be used. Digital computer subprograms (in FORTRAN 4 language) were developed and documented implementing the mathematical models.
