This book was released on 1973 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: A simplified flow field solution has been programmed in an attempt to improve the accuracy of estimates of the static aerodynamic characteristics of ordnance projectiles. It provides estimates of drag, normal force, static moment, and roll damping moment for pointed bodies of revolution at supersonic speed. The program combines the Van Dyke hybrid theory for potential flow, the Van Driest compressible turbulent boundary layer theory, and the Chapman-Sternberg model for supersonic base pressure. Good agreement is demonstrated between the theoretical and experimental data.

This book was released on 1952 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: A semiempirical profile-correction factor is discussed which enables the estimation of the wave-drag coefficient due to thickness at supersonic speeds for three-dimensional wings with arbitrary airfoil section (subject to restrictions of the thin airfoil theory) through use of previously calculated or known drag coefficients.

This book was released on 1956 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summary: The problem of designing an aircraft which will develop high lift-drag ratios in flight at high supersonic speeds is attacked using the elementary principle that the components of the aircraft should be individually and collectively arranged to impart the maximum downward and the minimum forward momentum to the surrounding air. This principle in conjunction with other practical considerations of hypersonic flight leads to the study of configurations for which the body is situated entirely below the wing; that is, flat-top wing-body combinations. Theory indicates that sensibly complete aircraft of this type can be designed to develop lift-drag ratios well in excess of 6.

Download or read book Estimation of Flight Performance with Closed form Approximations to the Equations of Motion written by Charlie M. Jackson and published by . This book was released on 1966 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: An approximate method for calculating climb and acceleration performance of an air-breathing aircraft has been developed. Basically, the method involves linearization of the equations of motion to obtain closed-form expressions for the desired performance parameters. These expressions are applied over finite velocity intervals where the aerodynamic, propulsion, and flight-path parameters are assumed to be constant. The method is extended by a rapidly convergent iteration procedure to estimate the climb performance for a flight path limited by sonic-boom considerations. Typical examples are presented where the performance is estimated for an air-breathing boost mission to hypersonic speeds and for a complete supersonic-transport mission. The examples illustrate the simplicity of the method and show that the estimated performance is in good agreement with the results of a numerical integration of the equations of motion. The application of the approximate method to these examples indicates the utility of the method for producing performance estimates suitable for preliminary airframe design, sizing studies, propulsion-system evaluation, and cursory heat-transfer and inlet-flow-field determinations along a flight path. In order to increase the utility of the method further, nomograms are presented which provide rapid solutions to the approximate performance equations.

Download or read book Estimated Lift drag Ratios at Supersonic Speed written by Robert T. Jones and published by . This book was released on 1947 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent developments in supersonic flow theory are applied to obtain estimates of the lift-drag ratios that may be achieved by aircraft employing swept-back wings. Lift-drag ratios greaterr than 10 to 1 can be maintained up to a Mach number of 1.4 bythe use of large angles of sweep and high aspect ratios. As the speed increases in the supersonic range the attainable lift-drag ratios decrease and the gain due to sweepback also appears to diminish. An efficient configuration for M = 1.4 would require about 60 degrees sweepback, an aspect ratio of 4 and a wing loading of one-third the atmospheric pressure. For a wing loading of 50 pounds per square foot the cruising altitude would be 60,000 feet and the indicated airspeed 290 miles per hour.

Download or read book Aerodynamic Principles of Flight Vehicles written by A. G. Panaras and published by AIAA (American Institute of Aeronautics & Astronautics). This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In "Aerodynamic Principles of Flight Vehicles" Argyris Panaras examines the fundamentals of vortices and shock waves, aerodynamic estimation of lift and drag, airfoil theory, boundary layer control, and high-speed, high-temperature flow. Individual chapters address vortices in aerodynamics, transonic and supersonic flows, transonic/supersonic aircraft configurations, and high-supersonic/hypersonic flows, beginning with definitions and historical data, and then describing present-day status and current research challenges. Emphasis is given to flow control, to the evolution of flight vehicle shapes as flight speed has increased, and to discoveries that enabled breakthrough developments in flight. The book: examines why various equations and technologies were developed, explains major contributors in areas such as vortices and aircraft wakes, drag buildup, sonic boom, and shock wave-boundary layer interactions, among others, and helps readers apply concepts from the material to their own projects. Archival and encyclopedic, "Aerodynamic Principles of Flight Vehicles" is a superb reference for aeronautical students and professionals alike. Although most beneficial to readers with a working knowledge of aerodynamics, it is accessible to anyone with an introductory understanding of the field.
