Method and apparatus for singularity avoidance for control moment gyroscope (CMG) systems without using null motion (The United States of America as represented by the Secretary of the Navy, Washington, DC (US), 2017-02-14);A method is described for avoiding gyrocopic singularities during attitude correction to a sytem, such as a spacecraft having a CMG array. The method receives a corrective torque vector µ and gimbal angle values δ for ...
Resonant octupole strength at 13 MeVin (58)Ni and (60)Ni and the character of the 53A(-1/3) state in heavy nuclei (Monterey, California. Naval Postgraduate School, 1977);Inelastic electron scattering reveals a concentration of resonant E3 strength at (13.3 ± 0.2) MeV in 51Ni and (12.8 ± 0.2) MeV in 60Ni. The energy agrees closely with the 52 A- 1/ ' MeV predicted by Hamamoto for the ...
(SAE International, 2016);The SPA-10 project, sponsored by U.S. National Science Foundation, is to acquire and qualify a replacement for the retired T-28 “storm penetration” aircraft previously used to acquire meteorological data to enable ...
