The use of carbon composites has continuously increased in the commercial aircraft industry due to more challenging weight targets which is one way to handle the environmental requirements to lower the CO2 emissions. One type of aircraft structure component made at Saab Aerostructures is long and slender U-sections manufactured in carbon composites. The manufacturing is performed by manual layu...

Traditional commercial aircraft design attempts to improve performance and reduce operating costs by minimizing takeoff weight. A better design approach also takes into account factors such as aircraft demand, market uncertainty, and development and manufacturing costs. This paper presents a design methodology that integrates an aircraft performance model with a program valuation technique base...

Developed by Dr. T.P. Wright in 1936, learning curves projected World War II production capacities. Afterward they became standard in the aircraft industry. In defense contracting, an expected learning rate is often factored into negotiations. However, learning curves seemingly made little impact on manufacturing progress in aviation or elsewhere. The history of the learning curve illustrates o...

Objectives The objective of this work is to develop a continuum sensitivity finite element analysis for the robust design of multi-stage metal forming processes in aircraft manufacturing. The computational forming design simulator being developed is applied to industrial forming design and provides the means to select the sequence of deformation processes, design the dies and preforms for each ...

The paper addresses the design of agile cells for manufacturing low volume aircraft sub-assemblies and focuses on the problem of robust grasping and handling carbon fiber fabric. The difficulty of the manufacturing task is faced equipping the cell with two cooperative robots. Both robots use purposely developed. The paper presents in detail the adaptive end-effectors purposely developed like ro...

Abstract The process of metal additive manufacturing (AM) is now widely used in fabricating complex parts today’s industry. scope this paper to redesign a for aircraft components using wing ribs as example by considering embedded Internet Things (IoT) sensory capability that can be an Industry 4.0 ecosystem moving away from condition-based preventive maintenance system data-driven predictive ma...
