Book A Non gaussian Turbulence Simulation

Download or read book A Non gaussian Turbulence Simulation written by Paul M. Reeves and published by . This book was released on 1969 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comparison of the statistical properties of low altitude atmospheric turbulence and the characteristics of presently used simulation techniques shows that these techniques do not satisfactorily account for the non-Gaussian nature of turbulence. A non-Gaussian turbulence simulation, intended to be used in conjunction with piloted flight simulators, is developed. The simulation produces three simultaneous random processes which represent the three orthogonal gust components. The probability distribution of each component is characterized by a modified Bessel function. The rms intensity and scale length of each component are independent parameters. A general method of introducing cross spectra between components is demonstrated. The multiplication of independent random processes is used to generate each of the gust components. Gaussian white noise generators, analog multipliers, and linear filters are used throughout the simulation. A complete analog circuit diagram is presented. (Author).

Book Atmospheric Turbulence Simulation Techniques with Application to Flight Analysis

Download or read book Atmospheric Turbulence Simulation Techniques with Application to Flight Analysis written by Show-Tien Wang and published by . This book was released on 1980 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Statistical modeling of atmospheric turbulence is discussed. The statistical properties of atmospheric turbulence, in particular the probability distribution, the spectra, and the coherence are reviewed. Different atmospheric turbulence simulation models are investigated, and appropriate statistical analyses are carried out to verify their validity. The models for simulation are incorporated into a computer model of aircraft flight dynamics. Statistical results of computer simulated landings for an aircraft having characteristics of a DC-8 are reported for the different turbulence simulation techniques. The significance of various degrees of sophistication in the turbulence simulation techniques on the landing performance of the aircraft is discussed.

Book Flight Simulation

Download or read book Flight Simulation written by J. M. Rolfe and published by Cambridge University Press. This book was released on 1988-05-12 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the complexity and capability of flight simulators have matched the growth of aerospace technology, there has until now been no textbook dealing specifically with the design and construction of flight simulators. This is a primary purpose of Flight Simulation. Written in collaboration with a number of internationally known specialists, the book considers the subject in three sections. Firstly it introduces the concept of simulation in order to identify the essential elements which make up the modern flight simulator. The development of these elements is also traced through the historical evolution of flight simulation. The main section of the book commences with an exposition of the mathematical models into dynamic physical devices capable of representing the response of a specific aircraft and its systems. The simulation of the flight environment is also covered in relation to cockpit motion systems and methods of representing the external visual scene. Another important aspect of simulation, the design of instructor and operating stations, is given separate attention. The final section considers the application of flight simulation to research and training and concludes with an appraisal of future prospects and developments.
