Aerostructures assembly (ASA) is a vital process in any aircraft production phase that integrates individual detail parts, sub-assemblies, major assemblies, components, and systems into a final deliverable, a completed aircraft structure fit for flight. ...ASA depends on highly skilled manual labor work across the global aerospace supply chain for various assembly processes and subprocesses required for assembling detail parts into sub-assemblies and components to achieve the design intent of the load-carrying aerostructure that is airworthy for the complete operational cycle till disposal of an aircraft. ...The 6M enhanced framework is used to create as a process design tool, and the outputs of the research are converted in assessment guidelines, which were validated by a global aerospace accreditation body for its adoption in the aerostructures supply chain. This paper can also be used as a reference guide by ASA engineers to readily identify the factors that can impact any process, ensuring the highest quality and reliable aerostructures products to customers ensuring cost-effective On-Time Delivery (OTD).

An Aircraft’s assembly process plays a vital part in its design, development and production phases and contributes to about half of the Total cost spent in its entire product lifecycle. Design For Assembly (DFA®) principles have been one of the proven effective methodologies in Automotive and Process industries. Use of DFA® principles have resulted in proactively simplifying and optimizing engineering designs with reduced product costs, and improved efficiencies in product design and performance. Standardization of Assembly guidelines is vital for “Design and Build” and “Build-To-Print” manufacturing supplier organizations. However, Standardizing design methodologies, through use of proven tools like Advanced Product Quality Planning, (APQP) are still in the initial stages in Aerospace part and process design processes.

A Study on Mitigating Head Gap Defects due to Radius of Externally Threaded Fasteners in Aerostructures Assembly

Externally threaded fasteners such as HI-LOK™, HI-TIGUE™, and HI-LITE™ fasteners are used in Aerospace Industry for their light weight, high strength, and controlled preloaded designs. These pins are offered in a variety of head styles, materials, finishes, and coatings. The pins are easily installed from one side, by one person, and quietly without the conventional riveting noise. In the design specifications of these pins, there is a radius R provided under the head which is to be accounted during manufacturing. The head radius, R comes with a manufacturing tolerance of 0.015 to 0.025 inch for standard sizes of 5/32 inch and 0.020 to 0.030 inch for higher sizes for protruding heads and similarly vary from 0.020 to 0.030 inch for 5/32-inch flush head style. As a general assembly practice, it is essential to deburr the edge of the holes to accommodate the head radius of the pins.

Collins Aerospace brings next gen avionics to Portuguese C-130s

2019-02-28
The aging Lockheed C-130 Hercules military transport platform is used by numerous countries for military and government logistics. The aircraft first flew in 1954, and in order to stay relevant, Collins Aerospace has developed a Flight2 aftermarket avionic solution to upgrade communications, navigation, surveillance, and air traffic management (CNS/ATM) capabilities. Collins’ latest customer, the Portuguese Air Force, will use Flight2 to upgrade avionics and enable their fleet of C-130H aircraft to communicate in next generation airspace.
