Book Description




Advanced Non-Intrusive Instrumentation for Propulsion Engines


Book Description

Changes in engine technology such as higher temperatures, higher tip speeds, new metal/composite/ceramic materials together with radical changes in design philosophy will require amongst other prerequisites the ability to measure and to monitor key internal gas and structural characteristics. The symposium papers presented non-intrusive measurement and analysis technologies in the following categories: (1) Laser Point Measurements (11); (2) Absorption and Infrared Techniques (4); (3) Paints; (4) Surface Sensors (6); (4) Laser Induced Fluorescence (6); (5) Mechanical (7); (6) Films (5); and (7) Laser Planar Measurement (9) and a Keynote Address.







Engineering of Solid Rocket Motors


Book Description

In the last few years, the aerospace industry has grown exponentially for both military and civil applications. This book explores the systems engineering, production processes and performance issues which happen constantly during solid rockets operations and flight. It also discusses state of the art experiments and techniques, as well as many recent developments. The book will appeal to rocket scientists, students and lecturers, senior scientists and professors.




Particle Image Velocimetry


Book Description

This book summarizes the main results reached using the EC-funded network PivNet 2. It also presents a survey of the state of the art of scientific research using PIV techniques. You get a clear introduction to the basics of these techniques. The authors then guide you through current and possible future applications for flow analysis, including combustion and supersonic flow. Hundreds of illustrations, many in full color, are provided.




Non-intrusive Sensing Techniques for Advanced Turbine Engine Structures


Book Description

This paper presents an overview of current research efforts aimed at improving turbine engine structural instrumentation capabilities. Emphasis is placed on non-intrusive concepts which will be applicable to the advanced engines currently being designed for initial operational testing around the turn of the century. Technologies to be described include; blade tip deflection sensors to determine dynamic stress, thermographic phosphors to measure metal temperature, fiber optics to measure both temperature and steady-state strain while embedded in composites, and neutron diagnostic techniques. Advantages of the various systems, potential problems and limitations, as well as, an assessment as to when the various technologies are likely to be ready for actual engine test usage are discussed.

Pressure and Temperature Sensitive Paints


Book Description

Luminescent molecule sensors, called pressure-sensitive paint (PSP) and temperature-sensitive paint (TSP), measure factors essential for understanding the aerodynamic performance and heat transfer characteristics of flight vehicles. They provide a powerful tool for experimental aerodynamicists to obtain a deeper understanding of the rich physical phenomena in complex flows around a flight vehicle. This book helps the reader to understand the physics and chemistry and the capabilities of PSP and TSP. It provides an overview of the wide scope of applications and explains the system requirements for using these sensors. The book also includes an extensive table of properties of PTP and TSP. As such, it is a thorough and up-to-date coverage of the underlying physics and applications of luminescent molecules designed for global pressure and temperature mapping
