Available in PDF, EPUB and Kindle. Book excerpt: The book is a concise guide dealing with the subject of air turbulence and its methods of detection with particular applications to aviation turbulence. It begins with a general description of turbulence and provides a background into the nature and causes of atmospheric turbulence that affect aircraft motion, giving updates on the state-of-the-art research on clear air turbulence (CAT). Important physical processes leading to the Kelvin-Helmholtz instability, a primary producer of CAT, are also explained. The several categories of CAT along with its impact on commercial aviation are also presented in a separate chapter, with particular emphasis on the structural damages to planes and injuries. The central theme of the book deals with both the earlier and the latest CAT detecting methods and techniques for remote and in situ sensing and forecasting. A concise presentation of new technologies for reducing aviation weather-related accidents is also offered. A chapter on the weather accident prevention project of the NASA aviation safety program is also included. Additionally, the book ends with a full description of the recent research activities on CAT and future challenges in turbulence detection, prediction and avoidance.

This book was released on 1974 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the winter operations, from 1967 to 1971, of Clear Air Turbulence (CAT) research at Wallops Island, Virginia, the Weater Radar Branch of Air Force Cambridge Research Laboratories observed eighteen cases of significant turbulence, defined as cases of light-to-moderate or moderate intensity. The report presents the meteorological data for each of these cases, consisting of synoptic sea level and upper air charts and rawinsonde data, observations of clear air echoes with powerful radars, and aircraft data which are used to indicate the present location and intensity of the turbulence.

Download or read book Clear Air Turbulence a Bibliography 1950 1967 written by Dorothy E. Bulford and published by . This book was released on 1968 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clear air turbulence encounters can occur unexpectedly without any visual evidence or warning. As operations of higher altitude aircraft increase, the phenomenon is encountered more often. Clear air turbulence is defined as 'all turbulence in the free atmosphere of interest in aerospace operations that is not in or adjacent to visible convective activity (this includes turbulence found in cirrus clouds not in or adjacent to visible convective activity).' This bibliography consists of 578 references to technical reports, articles in periodicals, and books published during the past 17 years. References about other forms of turbulence such as that occurring with storms and airplane wake vortices are not included. (Author).

Download or read book Aviation Turbulence written by Robert Sharman and published by Springer. This book was released on 2016-06-27 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anyone who has experienced turbulence in flight knows that it is usually not pleasant, and may wonder why this is so difficult to avoid. The book includes papers by various aviation turbulence researchers and provides background into the nature and causes of atmospheric turbulence that affect aircraft motion, and contains surveys of the latest techniques for remote and in situ sensing and forecasting of the turbulence phenomenon. It provides updates on the state-of-the-art research since earlier studies in the 1960s on clear-air turbulence, explains recent new understanding into turbulence generation by thunderstorms, and summarizes future challenges in turbulence prediction and avoidance.

Download or read book Study of Techniques for Detection and Measurement of Clear Air Turbulence written by Raymond E Zirkle (Jr) and published by . This book was released on 1966 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two general ways in which laser optical radar (optar) might be useful for clear air turbulence detection were examined. The first method involves spectral analysis of doppler-shifted light, backscattered by moving particles, to provide measures of average and gust spectrum velocity components. The second method involves the mapping of particle formations arrayed in the atmosphere by correlates of rough flying conditions such as wind shear, the jet stream, mountain waves, etc. Calculations show that the particulate matter of the troposphere which dominates optical backscatter is dynamically suitable for the mapping of wind motions consistent with anticipated requirements of CAT detection. Experiments by other groups have shown that laser doppler methods can measure particle velocities in the laboratory. Experimental extensions of these techniques will be needed to apply the concept to aircraft. An experimental program with pulsed ruby laser optars was conducted. Particle arrays were detected in both laboratory and field environments, but no evidence was obtained indicating a correlation with turbulent conditions. Laboratory turbulence-generated refractive index changes were much higher than those encountered in the atmosphere. Field tests at Rollinsville, Colorado were inconclusive due to poor weather conditions. Many cloud returns were obtained, but they were not related to mountain waves or turbulence. Airborne optars should be used in further work of this type to provide mobility and to allow direct correlation between signals received and turbulence encountered. (Author).

This book was released on 2018-09-23 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recognition of the importance of turbulence mitigation as a tool to improve aviation safety, NASA's Aviation Safety Program developed a Turbulence Detection and Mitigation Sub-element. The objective of this effort is to develop highly reliable turbulence detection technologies for commercial transport aircraft to sense dangerous turbulence with sufficient time warning so that defensive measures can be implemented and prevent passenger and crew injuries. Current research involves three forward sensing products to improve the cockpit awareness of possible turbulence hazards. X-band radar enhancements will improve the capabilities of current weather radar to detect turbulence associated with convective activity. LIDAR (Light Detection and Ranging) is a laser-based technology that is capable of detecting turbulence in clear air. Finally, a possible Radar-LIDAR hybrid sensor is envisioned to detect the full range of convective and clear air turbulence. To support decisions relating to the development of these three forward-looking turbulence sensor technologies, the objective of this study was defined as examination of cost and implementation metrics. Tasks performed included the identification of cost factors and certification issues, the development and application of an implementation model, and the development of cost budget/targets for installing the turbulence sensor and associated software devices into the commercial transport fleet.Kauffmann, Paul and Sousa-Poza, AndresGlenn Research CenterAIRCRAFT SAFETY; CLEAR AIR TURBULENCE; FLIGHT SAFETY; METEOROLOGICAL RADAR; OPTICAL RADAR; TURBULENCE; ASSESSMENTS; AUGMENTATION; CERTIFICATION; COCKPITS; COMMERCIAL AIRCRAFT; CONVECTION; COSTS; HAZARDS; INJURIES; LASERS; MARKET RESEARCH; RADAR DETECTION; SUPERHIGH FREQUENCIES
