Available in PDF, EPUB and Kindle. Book excerpt: The importance of mathematical models in designing a rocket is apparent in savings of time and money. Testing of certai theories of rocket flight can be done only by mathematical models. Such a model is given for a ballistic rocket, one for which there is no guidance after launching. It consists of six simultaneous differential equations which can be numerically solved rather quickly on a high-speed computer. All necessary parameters are completely defined, but the equations of motion are given without proof. The use of perturbation equations, which describe changes in the trajectory due to small changes in the atmospheric or rocket data, is discussed, indicating how their use can greatly increase computing speed. Numerical integration of the equations is discussed, together with the characteristics one would desire in a computer program which make the model as complete and flexible as possible. Some indication of computing speed is given, as well as the time required to program the model for a high speed computer. Finally, several applications for which the model was designed are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: The equations of motion which describe the position in space, the pitch, yaw, and roll of an unguided rocket are developed. Some effects considered are those of gravity, thrust, spin rockets, canted fins, aerodynamic forces and moments, loss of mass, rotation of the earth, wind, variable speed of sound, and variable atmospheric pressure. The vector forces and moments are defined and resolved into suitable components from which the equations of motion are derived. The problem of numerical integration of these equations is discussed. How perturbation techniques can be used to increase the computation speed is shown. Applications of the resulting mathematical models including prediction of the impact point for real-time support of an actual firing are explained. (Author).

This book was released on 1958* with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: While the linear theory has been the backbone of ballistic missile design and has served with excellent success in its various forms over the years, recent spectacular missile flight failures have appeared unexpectedly and are unaccounted for by this linear theory. It is these flight failures which now require attention and consideration of the non-linearities in the fluid force and moment system which contribute to missile flight performance and dynamic stability. Two types of non-linear flight instability have been isolated and identified as NonLinear Magnus Instability, and Catastrophic Yaw. It is these 2 flight instabilities which will be discussed. Approximate mathematical models will be suggested for the evaluation of missile dynamic stability. Both experimental and analytical applications of these models will be made and discussed.

Available in PDF, EPUB and Kindle. Book excerpt: US Strategic Command (USSTRATCOM) is developing a new linear programming model called the Weapons Assignment Model (WAM) to perform weapons assignment for the Strategic Integrated Operations Plan (SIOP). One of the major improvements WAM will have over its predecessor is the ability to include Multiple Independently Targetable Reentry Vehicle (MIRV) footprinting constraints in the optimization process. In order to include MIRV footprint constraints in WAM, a methodology is needed to model the MIRV footprints in a manner that is consistent with the limitations of linear programming Two techniques for modeling MIRV footprints were developed. The first, Geometric Approximation (GA), uses a carefully positioned and sized ellipse on the earth's surface to model the capabilities of a Post Boost Vehicle (PBV) to disperse MIRVs. Any combination of targets within the ellipse is considered to constitute a feasible targeting plan for a missile. The second model is called Energy Space Transformation (EST). This model scales the distance each MIRV is displaced from the missile aimpoint to account for the PBV energy required to maneuver for each MIRV. The sum of the maneuvering energy for each MIRV is used to calculate the fraction of the PBV energy required to strike a particular combination of targets. Any combination where the fraction is less than one is considered feasible. These two models were tested and verified using 120 missile sorties. Both models were approximately 85 percent accurate.
