Stability of Spinning Spacecraft with Partially Liquid-Filled Tanks
نویسنده
چکیده
This paper presents general stability conditions for a spinning spacecraft with partially liquid-filled tanks by using Rumyanstev and Mclntyre methods. These methods are compared for accuracy and limitation by applying them to a specific case of a spinning spacecraft with two partially liquid-filled tanks. The stability conditions require that, for a stable motion, the spin to transverse moment of inertia must be greater than 1 + C, where C is a positive definite function of the spacecraft parameters. Numerical spacecraft parameters are also used to determine minimum inertia ratios, 1 + C.

Dynamic Characteristics of Liquid Motion in Partially Filled Tanks of a Spinning Spacecraft
This paper presents a boundary-layer model to predict dynamic characteristics of liquid motion in partially filled tanks of a spinning spacecraft. The solution is obtained by solving three boundary-value problems: an inviscid fluid problem, a boundary-layer problem, and a viscous correction problem. The boundary-layer solution is obtained analytically, and the solutions to inviscid and viscous ...

متن کاملSurface Tension Lockup in the Image Nutation Damper – Anomaly and Recovery
Early telemetry from the spin-stabilized IMAGE spacecraft indicated that the vehicle’s initial nutation was not decaying. This behavior was especially puzzling because the spacecraft’s passive nutation damper behaved as expected while IMAGE was attached to the spinning upper stage. The lack of damping was also puzzling because the damper was a tubular ring partially filled with liquid mercury; ...
متن کاملBuckling Study of Thin Tank Filled with Heterogeneous Liquid
Buckling of imperfect thin shell tank which is subjected to uniform axial compression is analyzed. The effect of internal pressure on the stability of a shell tank filled with a homogeneous-heterogeneous liquid was considered. Investigation of the liquid nature effect on reduction of the shell buckling load is performed by using the finite elements method. Calculating results in terms of analyt...

This paper presents a Takagi-Sugeno fuzzy model-based controller which stabilizes the attitude of spacecraft with a partially-filled fuel tank. First, the nonlinear equations of motion of spacecraft containing a liquid fuel store is presented briefly. Then, the fuzzy modeling and the parallel distributed compensation control technique are applied. The proposed fuzzy controller is a nonlinear co...
