Process for Advanced Management and Technologies of Aircraft EOL

Abstract

Different possibilities are available to treat aircraft end-of-life (EOL), each with positive and negative impacts on the 3 spheres of sustainable development. EOL processing includes 4 major steps: decontamination, disassembly of reused or remanufactured parts, dismantling of the remaining carcass, materials recovery and valorization and/or landfill. In this paper, we present general methods to dispose of and/or implement profitable rebirthing processes and a dedicated infrastructure for end-of-life aircraft (real Bombardier CRJ100) and helicopters operated in Canada. This work is critical to help aircraft manufacturers design current and next generation aircraft and to facilitate disposal after use. The scope of this project is well rounded and includes all aspects related to dismantling of an aircraft; from legal, to scientific and engineering. These aspects are studied using both modeling and experimental approaches.

Disposal and Recycle Economic Assessment for Aircraft and Engine End of Life Solution Evaluation

“…Recent research on industrial EoL solutions include that regarding rolling stock [13], automobiles [14], ships [15], and aircraft vehicles [8,16,17]. The research focus ranges from the macro perspective of EoL strategies [8] to the micro perspective of the disassembly and dismantling process [18], as well as material management methods, i.e., the material recycling [19][20][21], and component management [17,22]. In addition, the economic and environmental impacts of the D&R process are also studied [4,23,24].…”

“…Moreover, methods are provided to generate appropriate EoL solutions. The following techniques are often used for strategy selection: alternative strategy modeling [16,28], network flow simulation [29], cost-benefit optimization [15], complex system modeling [28], reverse logistics analysis [17,30], and sustainability considering economic, social, and environmental balances [16,28,31].…”

“…Hur et al [22] investigated inventory control for aircraft spare parts based on continuous-time Markov chain model at the aircraft EoL phase. A component-oriented approach within a computer-aided system was implemented to integrate assembly and disassembly properties to support component management during the aircraft disposal process [17].…”

“…Based on the generalized disposal and recycle process, a specific process plan can be generated using various process planning techniques. The planning can be separated in three levels, depending on distinct levels of planning detail: the strategic level of reverse logistics, the tactical level of disassembly sequence planning and scheduling, and the operational level of detailed dismantling scheduling [17]. The strategic level planning utilizes techniques, such as network design and system dynamics [8].…”

A Lean based process planning for aircraft disassembly

“…(MASCLE et al, 2015) In our case, the goal is to integrate the lean paradigm in the disassembly process, but an airplane is a large product, different areas of work will be existed. Therefore, technical operations are dispersed in different zones of airplane and may have to be performed simultaneously.…”
