The airworthiness of aircraft is valid only if all engines, structures and avionics systems are checked periodically and the faults are maintained according to international aviation maintenance rules such as FAA or EASA requirements. This study examines extensive corrosion damage seen in the aft cargo compartment of a Boeing 737-300, which was taken into My Technic Aircraft MRO Services' Hangar, ISG International Airport-Istanbul, Turkey for the C check and structural repair. Through structural maintenance, many structural parts, including sections of the skin of the aircraft, were exchanged and repaired because the corrosion was quite extensive. The aluminum alloy patches used for skin repair were prepared by means of the English Wheel Tool. As a result, the corrosion damage on the skin was fixed by using a five-stage patch with dimensions of 2.7 meters in length and 1.6 meters in width.

An algorithm for designing nonlinear springs, or nonlinear dampers, using a mechanical force generator and its application to an aircraft landing gear Yıldız, Fatih; Soylu, Reşit; Department of Mechanical Engineering (2021-12-03) The landing gear system is one of the most critical aircraft sub-systems that takes part in the landing, taxi and take-off phases of every aircraft. Its main function is the absorption of part of aircraft's kinetic energy during landing. There are different types of shock absorbers to perform this task. The performance of the shock absorbers has developed a lot after the invention of air-oil type shock absorbers. However, increasing the performance of these shock absorber elements is still a field of resear...
Integrated aircraft and passenger recovery with cruise time controllability Arikan, Ugur; Gürel, Sinan; Akturk, M. Selim (Springer Science and Business Media LLC, 2016-01-01) Disruptions in airline operations can result in infeasibilities in aircraft and passenger schedules. Airlines typically recover aircraft schedules and disruptions in passenger itineraries sequentially. However, passengers are severely affected by disruptions and recovery decisions. In this paper, we present a mathematical formulation for the integrated aircraft and passenger recovery problem that considers aircraft and passenger related costs simultaneously. Using the superimposition of aircraft and passeng...
Performing helicopter maneuvers with optimization methods Tosun, Fatih; Yaman, Yavuz; Department of Aerospace Engineering (2020-8) In order to certificate a helicopter, aviation safety agencies must know that all designed helicopter configurations can withstand all loads resulting from maneuvers defined in certification standards. In other words, the maneuvers defined in regulations must be performed for each appropriate combination of weight and center of gravity. Then, designers have to prove that the helicopter can fly safely across the entire flight spectrum. Therefore, load engineers perform all maneuvers defined in the heli...
Determination of dynamically equivalent fe models of aircraft structures by using modal test data Karaağaçlı, Taylan; Özgüven, Hasan Nevzat; Yıldız, Erdinç N.; Department of Mechanical Engineering (2010) Reliable flutter analysis of aircraft structures is a major requirement to determine safe flight envelops. Dynamically equivalent finite element model of an aircraft structure correlating well with experimental modal is a major requirement for a reliable flutter analysis. Currently available model updating techniques require enormous time and engineering work to achieve appropriate finite element models of aircraft structures. The method developed within the scope of this thesis work aims to remove importan...
