Unsettled Technology Domains in Aerospace Additive Manufacturing Concerning Safety, Airworthiness, and Certification

To be published on 2019-12-20 by SAE International in United States
Additive manufacturing (AM) is currently being used to produce many certified aerospace components. However, significant advantages of AM are not exploited due to unresolved issues associated with process control, feedstock materials, surface finish, inspection, and cost. Components subject to fatigue must undergo surface finish improvements to enable inspection. This adds cost and limits the use of topology optimization. Continued development of process models is also required to enable optimization and understand the potential for defects in thin walled and slender sections. Costs are high for powder-fed processes due to material costs, machine costs, and low deposition rates. Cost for wire-fed processes are high due to the extensive post-process machining required. In addition, these processes are limited to low-complexity features. Incremental improvements in all of these areas are being made but a step change could potentially be achieved by hybrid processes, which use wire feedstock to deposit the bulk of the part and powder for fine detail. NOTE: SAE EDGE™ Research Reports are intended to identify and illuminate key issues in emerging, but still unsettled, technologies…

Unsettled Domains Concerning Electric Propulsion Technology for Commercial Aircraft

drR2 Consulting-Ravi Rajamani
  • Research Report
  • EPR2019006
Published 2019-12-13 by SAE International in United States
According to some, electric propulsion is already on its way down the “trough of disillusionment.” This report argues that while there are some concerns with associated technologies, such pessimism is unwarranted. Yes, battery systems can be more energy dense; charging standards are late in being developed; it is not clear what technologies and architectures will win out for which sectors; we still have to figure out how to deal with thermal management issues at all levels in future designs; and what might be the certification standards for electric aircraft. But that does not mean that these issues will not be solved. Yes, these unsettled questions may take a little longer to solve than originally estimated, but there is full expectation within the industry that electric propulsion for commercial aircraft will succeed. In this SAE EDGE Research Report we present points of view from leading researchers in the industry who are thinking deeply about solving these problems.
