Magnetic Attitude Control of Dynamically Unbalanced Spinning Spacecraft during Orbit Raising
Publisher: American Society of Civil Engineers
Abstract: In this article, the use of a magnetic attitude control system (MACS) in preparing a spacecraft for orbit circularization without the use of high-level torque-restoring actuators is investigated. The main task of the ...
Dynamics of a Cylindrical Pile in a Transversely Isotropic Half-Space under Axial Excitations
Publisher: American Society of Civil Engineers
Abstract: For the first time, a theoretical formulation is presented for the load-transfer analysis of an elastic cylindrical thin-walled pile immersed in a transversely isotropic half-space under axisymmetric excitations. By ...
Thermal Analysis of an Oil Jet-Dry Sump Transmission Gear Under Mixed-Elastohydrodynamic Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Improved fuel efficiency and reduced emissions are key drivers for modern drivetrain systems. Therefore, in recent years, dry sumps with air–oil mist lubrication have been used for efficient transmission design in order ...
