Book Description
Reported herein are the results of an investigation whose primary objective was to develop design criteria and performance tradeoffs for supersonic inlets applicable to advanced tactical aircraft. The objective was accomplished by conducting analysis and wind tunnel tests. The baseline models included a two-dimensional external compression inlet, a two-dimensional mixed compression inlet, and a half-axisymmetric external compression inlet. Alternate configurations for the external compression baseline inlets in the AEDC PWT-4T and VKF-A wind tunnels, respectively. The inlets were tested both isolated and in a non-uniform flow field, the later representing partial simulation of a vehicle flow field. Inlet steady state performance was characterized in terms of pressure recovery, pressure distortion, and turbulence levels at a simulated compressor face and immediately downstream of the inlet throat. In addition, detailed analysis and correlation of data obtained with high response dynamic instrumentation were made.

A Numerical Analysis of the Use of Perforated Walls to Control Shock Location and Movement in an Internal-compression Supersonic Inlet

Pages : 60
Book Description
This paper presents an analysis of the ability of a perforated wall in an internal-compression supersonic inlet to control the motion of the shock due to a variety of transients in the flow values at the engine face. The method of one-dimensional unsteady-flow characteristics was used to calculate the shock motion. The perforated walls were found to contain the shock within the inlet for appreciably larger transient magnitudes than was possible with solid walls.
Hypersonic Curved Compression Inlet and Its Inverse Design
Author: Kunyuan ZhangPublisher: Springer
ISBN: 9789811507298
Category : Science
Languages : en
Pages : 332
Book Description
This book presents systematic research results on curved shock wave-curved compression surface applied to the compression surface design of supersonic–hypersonic inlet, which is a brand new inlet design. The concept of supersonic inlet curved compression discussed originated from the author’s research at the Deutsches Zentrum fur Luft- und Raumfahrt (DLR SM-ES) in the early 1990s. This book introduces the research history, working characteristics, performance calculation and aerodynamic configuration design method of this compression mode in detail. It also describes method of estimating the minimum drag in inlet and drag reduction effect of curved compression and proposes a new index for evaluating unit area compression efficiency of the inlet. Further, it reviews the relevant recent research on curved compression. As such it is a valuable resource for students, researchers and scientists in the fields of hypersonic propulsion and aeronautics.
