Dr. Ahmed F. El-Sayed
Dr. El-Sayed is a Professor of Aerospace and Mechanical Power Engineering in the Aeronautical and Spacecraft Department at Zagazig University in Egypt. He worked as a technical inspector and R&D engineer in EgyptAir Company from 1970-1983, earning his Ph.D. from the Aeronautical Engineering Department, Cairo University, in 1980. In addition to being a professor at Zagazig University from 1983 to present, he has also worked as a visiting professor in several universities, military, and civil academies in USA, Russia, UK, Belgium, Austria, Syria, Libya, China, and Japan. He is a member of 10 International societies and institutions. He authored 11 International textbooks, two of which handle aircraft and rocket propulsion as well as gas turbine engines. He authored a forthcoming Wiley title (Bird Strike in Aviation), 2019. Moreover, he published some 100 technical papers and reports in international journals and conferences. He is consultant to Arab Organization for Industry (AOI) and Egyptian Academy for Research. He is the founder of four research groups in Zagazig, Helwan, and Cairo Universities, handling aircraft propulsion, particulate flows in industrial applications, wind energy, and aerodynamics & dynamics of automotive.

Abstract
Bird Strike is defined as a collision between an airborne animal (usually a bird or bat) and a man-made vehicle (i.e., rockets during launch and aircraft in flight or on a takeoff or landing roll). The Wright brothers recorded the first bird strike on September 7th, 1905. Nearly 7000 incidents and accidents are recorded every year. In this talk, major accidents in the last 60 years will be reviewed. Since 1988 more than 219 people have been killed worldwide as a result of bird strikes. Bird strikes cost up to $1.3 billion to commercial aircraft worldwide. Birds are classified based on their weight into 5 groups. According to the FAA, EASA, TC; 90% of bird strikes happen during takeoff or landing, or during low altitude flight. Less than 8% of strikes occur above 900 m (3,000 ft). Statistics for day and night accidents due to Bird Strike will be reviewed along with locations of aircraft damage due to bird strike (Boeing, Airbus, EASA, Russian statistics). Accident statistics by critical phases of flight will also be discussed. Moreover, accident statistics (year/parts of aircrafts/bird type/costs) for both civil and military Fixed and Rotary Wings aircrafts will be presented. Bird Strike management using different active and passive approaches to reduce accidents/incidents will be described in detail. Numerical (CFD) simulation of bird strike with wings/tails and engines are will be discussed. Experimental testing of bird strike with airframe and engines will also be described. Finally, bird identification using DNA and other methods will be highlighted.
