This essential information captures the state of the composites industry to assist engineering/technical professionals in charting a course for achieving economic success. The material characteristics of composites, their applications, and complex composites manufacturing processes depend on many factors. These are all fully considered and presented to meet the challenges that face this marketplace.

A new, automated production method of installing Lightweight Groove Proportioned (LGP) and Hi-Lok bolts in wing panels has been implemented by Electroimpact, Inc. The system inserts LGP and Hi-Lok bolts into interference holes using a ball screw mechanical squeeze process supported by a back side rod-locked pneumatic clamp cylinder. Collars are fed and loaded onto a swage die retaining pin and swaging is performed through ball screw mechanical squeeze. Offset and straight collar locations are accommodated for 99.99% coverage of fastener diameters of 3/16", 1/4" and 5/16". Collar stripping forces are resolved using a dynamic ram inertial technique that reduces the pull on the work piece. Titanium TN nuts are fed and loaded into a socket with a retaining spring and installed on Hi-Loks with a Bosch right angle nut runner. Bolt installation and collar swage loads, as well as nut torque values are captured and logged for future reference.

With the development of automated manufacturing processes for orthotropic laminates, it has become much easier to tailor the properties of laminates as per design considerations. Minimizing the stress concentrations around cutouts in a plate is often a design problem, especially in the Aerospace industry, one quick example being cutouts in a fuselage. A problem of optimizing spatially varying fiber paths in a symmetric, linear orthotropic composite laminate with a cutout, so as to achieve minimum stress concentration under remote unidirectional tensile loading is of interest in this study. A finite element model is developed to this extent, which constraints the fiber angles while optimizing the fiber paths, proving essential in manufacturing processes.

The Boeing Company has recently developed a mobile robotic drilling and fastening system, in support of its commitment to lean manufacturing techniques. The robotic system, referred to as Lower Panel Drilling and Fastening System (LPDFS), was initially developed as a way to minimize facilities costs by not requiring costly foundation work. It is designed to operate with a high level of autonomy, minimizing operator intervention, including that required for machine setup and tool changes. System design enables positioning the work piece at a lower ergonomic height for concurrent manual processes. In all aspects of design, the system will maintain maximum flexibility for accommodating future manufacturing changes and increases in production rate, while meeting the strict accuracy requirements characteristic of aircraft manufacturing.

Abstract The significant problem of engine power-loss and damage associated with ice crystal icing (ICI) was first formally recognized by the industry in a 2006 publication [1]. Engine events described by the study included: engine surge, stall, flameout, rollback, and compressor damage; which were triggered by the ingestion of ice crystals in high concentrations generated by deep, moist convection. Since 2003, when ICI engine events were first identified, Boeing has carefully analyzed event conditions documenting detailed pilot reports and compiling weather analyses into a database. The database provides valuable information to characterize environments associated with engine events. It provides boundary conditions, exposure times, and severity to researchers investigating the ICI phenomenon. Ultimately, this research will aid in the development of engine tests and ICI detection/avoidance devices or techniques.
