Abstract

A bird strike is a critical problem in the context of safety in the aviation industry. All modern aircraft structures are designed with account of likely collision with birds. Thus, aviation standards in force require that the aircraft construction would allow the crew to conclude the flight safely after collision with a 1.81-kg bird. A method for analysing the stress-strained state of laminated airplane glazing at different operational factors is presented. The method includes a technique for strength analysis of the laminated airplane glazing at bird impact, and a technique for analysis of excess pressure. The model of laminated glazing is based on the refined first-order theory accounting for transverse shear strains, thickness reduction and normal element rotation inertia in each layer. The mathematical model of the pressure impulse authentically reproducing the bird impact is based on experimental research. Theoretical results are in good agreement with experimental data, thus allowing to recommend the method to develop new airplane glazing elements.

Highlights

Collisions between birds and aircraft during the take-off, cruising and landing phases are events of serious concern as regards aircraft safety
According to the statistical data of the Federal Aviation Administration, the number of bird strike accidents annually has increased six-fold from 1,795 to 10,856 incidents in the years 1990 and 2013, respectively, with a total of 138,257 incidents over 14 years. Such intensive bird strike incidents have caused huge fatalities, namely, at least 103 aircraft and 262 lives were lost in civil aviation during 1912-2008, with annual property losses increasing from 614 million to 1.28 billion US dollars [1,2,3]
40% of major bird strike incidents with civil aircraft can be attributed to engine ingestion, 33% to collision with wings, 16% with windshields, and 7% with fuselages
