About this book

This book describes systematically telemetry theory and methods for aircraft in flight test. Test targets of telemetry in flight test include airplanes, helicopters, unmanned aerial vehicles, aerostatics, carrier-based aircraft, airborne equipment (systems), weapon systems, (powered) aircraft scale models, aircraft external stores (e.g., nacelle, auxiliary tanks), and ejection seats and so on. The book collects the author's telemetry research work and presents methods that have been verified in real-world tests. The book has eight chapters: the first three discuss the theoretical basis of telemetry, while the other five focus on the methods used in flight tests.Unlike other professional textbooks, this book describes the practical telemetry theory and combines theory and engineering practice to offer a comprehensive and systematic overview of telemetry in flight test for readers.

Chapter 1. Overview
Abstract
As an important part of developing aeronautical science and technology, flight test refers to indispensable practices to investigate and study new principles and technologies in the field of aviation.

Chapter 2. Basic Theory of Flight Test Telemetry
Abstract
As an important branch of telemetry science, flight test telemetry involves the basics of many disciplines such as analysis of time-domain discrete signals, parameter estimation, fuzzy mathematics, and test error theories. This chapter introduces signals and noises, Fourier-series transform, Z-series transform, Wavelet, and the basic methods of test parameter estimation in flight test telemetry. In the end, fundamental concepts of fuzzy mathematics and error theory are presented.

Chapter 3. Aviation Sensors and Their Calibration
Abstract
Sensor technology is an important component of flight test telemetry technology. In flight tests, thousands of sensors (or transducers) are being used. They are a crucial part of the airborne data collection system. In some extent, the sensors play a decisive role in determining the measurement accuracy of a telemetry system.

Chapter 4. Airborne Data Acquisition and Recording
Abstract
The airborne data acquisition and recording now faces the challenge of the linearly rising number of test parameters caused by the increasing improvement, complexity, and comprehensiveness of modern aircraft.

Chapter 5. Telemetry Information Transmission
Abstract
The transmission of telemetry information is a process in which the airborne data collection system collects data and sends them to the parameter selector to pick out the key parameters that are then transmitted by the telemetry transmission system and received by the ground telemetry receiving system, to achieve real-time flight safety monitoring.

Chapter 6. Telemetry Data Processing and Analysis
Abstract
Telemetry data processing and analysis is one of the important contents of flight test telemetry. The telemetry data are discrete quantities (data) based on time series. The sampling rate of telemetry parameters are different, and there are slow variables and fast variables; some are direct measurement parameters, and some are indirect measurement parameter (derived from the calculation model, sometimes called derived parameters or calculation parameters).

Chapter 7. Test Data Management and Data Mining
Abstract
Flight test is a scientific study to carry out the identification and evaluation of military products under real flight conditions. Flight test data truly reflects the tactical and technical performance index and comprehensive combat effectiveness of an aircraft and its airborne system in the real atmosphere environment, and it is the most direct and important basis for type design finalization/identification and aviation science exploration. This chapter introduces the flight test database management method, data mining algorithm, and the application of cloud technology in flight test telemetry.

Chapter 8. Integrated Space–Ground Telemetry Network
Abstract
With the advent of network-centered system of systems (SoS) like C4ISR, air–ground integration, air–sea integration, and global information grid (GIG), current test and evaluation methods cannot meet SoS test and evaluation (T&E) needs. T&E theories and methods of the complicated weapon systems (large combat network) are still under research and exploration.
