The Western Aeronautical Test Range of NASA Ames Research Center [PDF]

open access: green23rd Aerospace Sciences Meeting, 1985
An overview of the Western Aeronautical Test Range (WATR) of NASA Ames Research Center (ARC) is presented in this paper. The three WATR facilities are discussed, and three WATR elements - mission control centerns, communications systems, real-time processing and display systems, and tracking systems -are reviewed. The relationships within the NASA WATR,

3D Modeling of the Elastic-Plastic Behavior of Thin Aeronautical Adhesive Films Suited for a Wide Range of Tensile/Compression-Shear Loads [PDF]

open access: greenThe Journal of Adhesion, 2013
Adhesive bonding is an interesting structural assembling technique for weight saving in modern commercial aircraft, in which the use of composites materials is increasing. In order to meet both optimization and respect of safety conception constraints, the development of accurate numerical strategies is required.

Potential Applications of Electrodynamic Tethers [PDF]

open access: yesInternational Journal of Aviation, Aeronautics, and Aerospace, vol. 8 (2021), iss. 4, no. 3, 2021
In recent decades, alternative propulsion systems have been investigated and have attracted great interest in the space community. Most of these alternative propulsion systems need propellants. One alternative propulsion system that does not require propellants and is not often discussed is electrodynamic tethers (EDTs).
