This book was released on 2018-06-16 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: This program addresses the development of high temperature structural seals for control surfaces for a new generation of small reusable launch vehicles. Successful development will contribute significantly to the mission goal of reducing launch cost for small, 200 to 300 lb payloads. Development of high temperature seals is mission enabling. For instance, ineffective control surface seals can result in high temperature (3100 F) flows in the elevon area exceeding structural material limits. Longer sealing life will allow use for many missions before replacement, contributing to the reduction of hardware, operation and launch costs. During the first phase of this program the existing launch vehicle control surface sealing concepts were reviewed, the aerothermal environment for a high temperature seal design was analyzed and a mock up of an arc-jet test fixture for evaluating seal concepts was fabricated.

This book was released on 2022-11-29 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smart manufacturing is a broad category of manufacturing that employs computer-integration, high levels of adaptability and rapid design changes, together with digital information technology and a technically-trained workforce. This book presents the proceedings of SMMP2022, the 2022 International Conference on Smart Manufacturing and Material Processing, held on 12 and 13 August 2022 as a virtual event due to continuing restrictions related to the COVID-19 pandemic, and hosted from Shanghai, China. The conference provides a platform for researchers and scientists from smart manufacturing and material sciences to come together with researchers from various other application areas to discuss problems and solutions, identify new issues, and shape future directions for research. The conference received 60 submissions. These were submitted to a rigorous peer review process by a committee of experts from various disciplines, after which, 23 were accepted for presentation at the conference and publication here. The topics covered include materials processing and product manufacture, sensors and smart material systems, functional materials, industrial automation and process control, and discussion of the state-of-the-art and future direction of smart manufacturing and material sciences. Providing an overview of current developments in smart manufacturing and material processing, the book will be of interest to all those working in the field.

This book was released on 2018-05-31 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Control surface seals are crucial to current and future space vehicles, as they are used to seal the gaps surrounding body flaps, elevons, and other actuated exterior surfaces. During reentry, leakage of high temperature gases through these gaps could damage underlying lower temperature structures such as rudder drive motors and mechanical actuators, resulting in impaired vehicle control. To be effective, control surface seals must shield lower temperature structures from heat transfer by maintaining sufficient resiliency to remain in contact with opposing sealing surfaces through multiple compression cycles. The current seal exhibits significant loss of resiliency after a few compression cycles at elevated temperatures (i.e., 1900 F) and therefore would be inadequate for advanced space vehicles. This seal utilizes a knitted Inconel X-750 spring tube as its primary resilient element. As part of a larger effort to enhance seal resiliency, researchers at the NASA Glenn Research Center performed high temperature compression testing (up to 2000 F) on candidate spring tube designs employing material substitutions and modified geometries. These tests demonstrated significant improvements in spring tube resiliency (5.5x better at 1750 F) through direct substitution of heat treated Rene 41 alloy in the baseline knit design. The impact of geometry modification was minor within the range of parameters tested, however trends did suggest that moderate resiliency improvements could be obtained by optimizing the current spring tube geometry.Taylor, Shawn C. and DeMange, Jeffrey J. and Dunlap, Patrick H., Jr. and Steinetz, Bruce M.Glenn Research CenterSEALING; STRUCTURAL DESIGN; CONTROL SURFACES; HIGH TEMPERATURE GASES; ACTUATORS; FLAPPING
