This paper explores a novel structural design concept for a demonstrator of a high altitude photovoltaic feeder airship. The presented structural design concept aims to minimize the use of strategic m....
Quality itself is no longer a differentiator among aerospace manufacturers. High quality is expected and achievable. With enough time and money, any manufacturer can turn around a high-quality product....
A cost effective, portable particulate control system was developed, built, and evaluated at the University of Louisiana at Lafayette. Prototype of the presented system was developed for experimental ....
To join sheet metal made out of aluminium, riveting is common practice. This process contains several disadvantages. On the one hand, large, specially designed and cost-intensive machines are used wit....
In order to machine a wide variety of materials with a single spindle and setup, a multi-purpose spindle for machine tools has been developed. The spindle achieves both high power/ torque for heavy du....
In the present study, a fully controlled experimental protocol is used to investigate the difference in milling Invar and HexTool® for composites curing tools. The main difference is the use of the di....
The challenging performance and affordability goals of next generation aircraft have accelerated the demand for advanced structural materials and concepts capable of achieving significant weight and c....
This paper documents the development of a novel CNC metal forming process called “Stretch roll forming”. It is an extension of the three roll forming (or slip-roll) process, wherein many pairs of roll....
Wing and fuselage aircraft structures require large precise tools for assembly. These large jigs require periodic re-certification to validate jig accuracy, yet metrology tasks involved may take the t....
Deep-hole drilling is among the most critical precision machining processes for production of high-performance discrete components. The effects of drilling with superimposed, controlled low-frequency ....
Premium AEROTEC has developed several concepts for an automated process chain in order to manufacture CFRP parts by means of an RTM process. The presented process is robot assisted and the degree of a....
The present paper characterizes the difference between metals and composite repairs in aerospace application. The main difference, focus on 5 axis scarfing instead of 2 axis sheet metal cutting, using....
Automated Fiber Placement (AFP) machines typically consist of 3 linear and 3 rotary axes of motion in order to manufacture complex shapes. These axes are generally orthogonal and semi-coupled. In thes....
The objective of this paper is to discuss challenges involved in the measurement of key characteristics in an integrated aircraft assembly line environment. The measurement process is complicated by t....
The objective of an engineering analysis - a numerical model and simulation designed to represent a specific manufacturing process - is not simply to determine the behavior and impact of that process ....
Many Aerospace Manufacturers desire to automate their painting processes to improve quality, reduce coating and other materials usage, and reduce labor content. Automated Painting Systems have been de....
Aerospace manufacturing is becoming more competitive and cost reduction is a key factor in building a competitive edge. Robotic technology has advanced tremendously over the past 25 years primarily du....
