This book was released on 1966 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook presents a general survey of the principal factors affecting the flight of projectiles, and describes the methods commonly used for predicting and influencing the flight performance. The coefficients which characterize the aerodynamic forces and moments of a moving body are identified, methods for determining the coefficients applicable to a projectile having a given shape and center of gravity location are described, and the coefficients of a number of projectiles and projectile shapes are given. The use of aerodynamic coefficients in predicting stability, range and accuracy is described. The effects of variations in projectile shape and center of gravity location on range, accuracy and lethality are discussed. Some material on prototype testing and the effects of round-to-round variations in production lots is presented.

Available in PDF, EPUB and Kindle. Book excerpt: A theoretical analysis is given of the unsteady flow within a liquid- filled cylinder of finite length, which is started impulsively to spin about its axis. It is established that a secondary flow, which is caused by the cylinder ends, has a remarkable effect on the generation of spin in the liquid. The theoretical results are compared with experimental observations and good agreement is found.

Available in PDF, EPUB and Kindle. Book excerpt: The unsteady motion of a fluid which fills a cylindrical container in a spinning projectile is considered. The spin is imparted impulsively to the cylinder and spin-up of the fluid is the basic flow which is perturbed to study the waves in the rotating fluid. The core flow is perturbed, not the Ekman layer flow. This is called the spin-up eigenvalue problem which is solved with modal solutions. Viscous perturbations are needed because of the boundary layer and critical layer. A numerical method of solution is given and several results shown. There are two times at which projectile instability might occur. The results of the theory and method are validated by comparison with experimental results.

Download or read book Liquid Moment on a Filled Coning Cylinder During Spin Up Ad Hoc Model written by N. Gerber and published by . This book was released on 1984 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: A liquid-filled right circular cylinder, coning at constant frequency and small amplitude, impulsively begins spinning with a fixed angular velocity. The ensuing history of the moment, i.e., pressure plus viscous shear, exerted by the liquid on the container is investigated here by computation of the quasi-steady state response of the fluid to the motion of the shell. The partial differential equations of flow are linearized, and a modal analysis (separated variable solution) is applied. The difficulty with endwall boundary conditions which arises from stipulating a modal analysis is avoided by specifying a heuristic boundary condition and then satisfying it aproximately. The current procedure for approximating the boundary condition is an improvement over the one employed in previous work (ARBRL-TR-02563) to obtain the pressure moment. Calculations indicate that peaks of overturning moment occur at or near those times when the coning frequency is equal to one of the frequencies of inertial oscillations of the liquid. This phenomenon of resonance extends the results of Stewartson obtained for inviscid perturbations in solid body rotation. Included here also are a discussion of the accuracy of a part of the method and comparisons with output of the inviscid perturbation method and the above-mentioned previous method.
