    Propulsion system performance, the gas generator Brayton cycle, zero dimensional analysis of ideal ramjet, turbojet and turbofan cycles, non-ideality and isentropic efficiencies. Performance analysis of inlets and nozzles, gas turbine combustors, compressors and turbines and discussion of . Abstract. Various papers on numerical methods for engine-airframe integration are presented. The individual topics considered include: scientific computing environment for the s, overview of prediction of complex turbulent flows, numerical solutions of the compressible Navier-Stokes equations, elements of computational engine/airframe integrations, computational requirements for efficient.

    Pulse detonation engines (PDEs) are new exciting propulsion technologies for future propulsion applications. The operating cycles of PDE consist of fuel-air mixture, combustion, blowdown, and purging. The combustion process in pulse detonation engine is the most important phenomenon as it produces reliable and repeatable detonation waves. The detonation wave initiation in detonation tube in Cited by: The renewed interest in high-speed propulsion has led to increased activity in the development of the supersonic combustion ramjet engine for hypersonic flight applications. In the hypersonic regime the scramjet engine's specific thrust exceeds that of other propulsion systems. This book, written by a leading researcher, describes the processes.

    multi-body aerodynamics. In high-speed propulsion systems, shock-boundary layer interaction (SBLI) can occur in intakes, supersonic combustion chambers and nozzles. Computational fluid dynamics (CFD) is routinely used to study SBLI flows and predict such interactions in geometries of practical interest. This volume - the third and final in a mini-series on hypersonic propulsion along with High Speed Flight Propulsion Systems, volume , and Developments in High Speed Flight Propulsion Systems, volume - presents a comprehensive and detailed exposition of the gradual maturing of scramjet technologies.

PERSPECTIVES ON HYPERSONIC VISCOUS AND NONEQUILIBRIUM FLOW RESEARCH H.K. Cheng Department of Aerospace Engineering University of Southern California Los Angeles CA FOREWORD This report (USCAE ) is based on a study prepared for the article "Perspectives on Hypersonic Viscous Flow Research" in the Annual Reviews of Fluid Mechanics.

Shown in Fig. is the hypersonic strong viscous interaction at the leading edge of the flat plate to create induced pressure zone.

Since there is a considerable pressure change at the leading edge region the analysis of the boundary layer in hypersonic flow must be quite different from the classical approach.

In the framework of the PVSL theory, systematic numerical solutions of some two- and three-dimensional hypersonic viscous gas flow problems past blunt bodies for a wide range of Reynolds numbers and body shape are obtained; the accuracy and the applicability range of the suggested model are estimated on the basis of comparisons with theoretical Cited by: 1.

A computational study of hypersonic air ow over a three-dimensional blunt leading edge is carried out to investigate the energy deposition due to an arc discharge along the surface.

The discharge is the result of an imposed potential di erence between two ush-mounted electrodes. The energy deposition is the result of Joule heating, which is. Gas turbine engines (GTEs) for aircraft GTE have undergone continual evolution and improvement since their introduction during World War II.

As shown in Figurefundamental engine performance parameters have been significantly r, there remains substantial potential for improvement beyond the current state of the art for fielded military engines, which must undergo.

Great efforts have been dedicated during the last decades to the research and development of hypersonic aircrafts that can fly at several times the speed of sound. These aerospace vehicles have revolutionary applications in national security as advanced hypersonic weapons, in space exploration as reusable stages for access to low Earth orbit, and in commercial aviation as fast long-range Cited by: Hypersonic Flow Hypersonic Vehicles Effects of High Mach Number Effects of High Temperature Viscous Hypersonic Flow Effects of Low Density Approximate Analyses of Inviscid Hypersonic Flow Aerodynamic Heating FTT: Hypersonic Flight Testing Scramjet Nozzles 46th AIAA/ASME/SAE/ASEEJoint Propulsion Conference&Exhibit Integration with hypersonic vehicle Three-dimensional vehicle with triangular panels Propulsion flowpath modeled as two-dimensional Vogel, J.
