Download or read book Ice Accretion and Icing Technology written by Robert J Flemming and published by SAE International. This book was released on 2015-04-16 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of inflight atmospheric icing can be devastating to aircraft. Universities and industry have been hard at work to respond to the challenge of maintaining flight safety in all weather conditions. Proposed changes in the regulations for operation in icing conditions are sure to keep this type of research and development at its highest level. This is especially true for the effects of ice crystals in the atmosphere, and for the threat associated with supercooled large drop (SLD) icing. This collection of ten SAE International technical papers brings together vital contributions to the subject. Icing on aircraft surfaces would not be a problem if a material were discovered that prevented the freezing and accretion of supercooled drops. Many options that appeared to have promising icephobic properties have had serious shortfalls in durability. This title addresses, among other topics, the measurement techniques and the drop physics that apply to icing, certification for flight through ice crystal clouds and in supercooled large drops, improvements in predictive techniques, scaling methods, test facilities and techniques, and rotorcraft icing.
Download or read book Aircraft Icing Weather Data Reporting and Dissemination System written by Ellen J. Bass and published by BiblioGov. This book was released on 2013-08 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The long-term operational concept of this research is to develop an onboard aircraft system that assesses and reports atmospheric icing conditions automatically and in a timely manner in order to improve aviation safety and the efficiency of aircraft operations via improved real-time and forecast weather products. The idea is to use current measurement capabilities on aircraft equipped with icing sensors and in-flight data communication technologies as a reporting source. Without requiring expensive avionics upgrades, aircraft data must be processed and available for downlink. Ideally, the data from multiple aircraft can then be integrated (along with other real-time and modeled data) on the ground such that aviation-centered icing hazard metrics for volumes of airspace can be assessed. As the effect of icing on different aircraft types can vary, the information should be displayed in meaningful ways such that multiple types of users can understand the information. That is, information must be presented in a manner to allow users to understand the icing conditions with respect to individual concerns and aircraft capabilities. This research provides progress toward this operational concept by: identifying an aircraft platform capable of digitally capturing, processing, and downlinking icing data; identifying the required in situ icing data processing; investigating the requirements for routing the icing data for use by weather products; developing an icing case study in order to gain insight into major air carrier needs; developing and prototyping icing display concepts based on the National Center for Atmospheric Research's existing diagnostic and forecast experimental icing products; and conducting a usability study for the prototyped icing display concepts.

Available in PDF, EPUB and Kindle. Book excerpt: Approximately 28,000 nautical miles (52,000 km) of select, in-flight measurements of cloud water concentrations, droplet sizes, temperatures, and other variables in supercooled clouds over portions of North America, Europe, and the northern oceans have been condensed into a computerized database for deriving a worldwide, statistical description of aircraft icing conditions aloft. The data are compared with the currently accepted envelopes of icing cloud variables specified in Title 14 Code of Federal Regulations Parts 25 and 29 Appendix C for the design of aircraft ice protection equipment. There are differences, along with some deficiencies, unrealistic trends, and difficulties in the use of Appendix C. As a result, suggestions are made for updating, modernizing, and improving the currently accepted envelopes in Appendix C.

Book excerpt: Icing of unprotected aircraft components is a major problem engineers are faced with during the development phase of an aircraft programme. Ice accretions as well as their shape have to be predicted in order to investigate their effect on aerodynamic flight safety and performance and to decide on the need for anti-or de-icing systems. The Fluid Dynamics Panel of AGARD sponsored a round-table discussion on the subject of Aircraft Icing, on 30 September 1977, in Ottawa, Canada, in conjunction with an FDP Symposium on Unsteady Aerodynamics. The seven papers presented, covering a broad spectrum of topics, are presented in this Advisory Report. (Author).

This book was released on 2018-07-17 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: A compact and rugged probe based on the phase Doppler method was evaluated as a means for characterizing icing clouds using airborne platforms and for advancing aircraft icing research in large scale wind tunnels. The Phase Doppler Particle Analyzer (PDPA) upon which the new probe was based is now widely recognized as an accurate method for the complete characterization of sprays. The prototype fiber optic-based probe was evaluated in simulated aircraft icing clouds and found to have the qualities essential to providing information that will advance aircraft icing research. Measurement comparisons of the size and velocity distributions made with the standard PDPA and the fiber optic probe were in excellent agreement as were the measurements of number density and liquid water content. Preliminary testing in the NASA Lewis Icing Research Tunnel (IRT) produced reasonable results but revealed some problems with vibration and signal quality at high speeds. The cause of these problems were identified and design changes were proposed to eliminate the shortcomings of the probe. Bachalo, W. and Smith, J. and Rudoff, R.

Book excerpt: In 2018, approximately 4.3 billion passengers were carried by scheduled flights in the member states of the International Civil Aviation Organization. To satisfy the needs of day and night flight operations even in situations of inclement weather, aircraft icing is an inherent component of the certification of large transport aircraft. Ice detection and protection systems ensure flight safety and must be designed carefully. The reliable prediction of ice accretion is a mandatory intermediate step that involves many challenging problems of fluid mechanics that will be treated in this volume. After introducing the topic of aircraft icing with a brief historical overview of technological and scientific progress over the last century, current challenges from the perspective of fluid mechanics are outlined. In particular, the governing boundary conditions of the phenomenon are highlighted, accompanied by remarks on non-dimensional groups and scaling laws. Selected physical properties of water and ice are elucidated. Classic ice accretion is usually triggered by the impact of supercooled droplets on a surface. After analysing the solidification process of supercooled water, drop impact is studied on both dry and wetted substrates. Macroscopic phenomena of ice accretion are considered using a combined approach of experiments and computations. To carry out experimental investigations, the Braunschweig Icing Wind Tunnel was built. Together with the results of the icing code TAUICE, the gathered data are used to develop a deeper understanding of the process of glaze ice accretion, which involves a broad range of physical phenomena, including wetting, roughness formation, transitional flow and heat transfer.
