In the first phase mathematical modeling of stationary motion in rigid supports of a rigid rotor
with a cylindrical chamber partially filled with fluid was carried out.
"The compound coaxial offset system requires us to have a fully rigid rotor
system," he said.
a canonical linear harmonic oscillator with a quadratic dependence of the potential energy on the displacement from an equilibrium condition, 2) a rotor with a fixed axis that produced an energy proportional to the square of a quantum number, 3) a rigid rotor
with a free axis that produced a rotational energy based on functional J (J + 1) and 4) a non-rigid rotor as a model of a diatomic molecule that produced again an energy dependent on the same functional.
It consists of a rigid rotor
disk with mass [m.sub.r] and 2DOF ([x.sub.r], [y.sub.r]), mounted on a massless elastic shaft, with stiffness [k.sub.r], and subjected to linear viscous damping [c.sub.r]; a viscoelastic suspended stator, with mass ms and stiffness [k.sub.s], and subjected to linear viscous damping cs, with two translational DOF ([x.sub.s], [y.sub.s]), is also considered.

Sikorsky proved the efficiency of the rigid rotor
co-axial design in 2010 when its 6,000-lb.
The moment of inertia of the associated band was found to be close to that of a rigid rotor
with a 2:1 axis rotation.
The initiator of that concept was Abe Karem, now CEO of Karem Aircraft, the system being based on a hingeless rigid rotor
with variable rotational speed, which is trimmed according to the flight situation.
This paper deals with the balancing of a rigid rotor
supported by hydrodynamic journal bearings by using plane separation technique and artificial neural networks.
* counter-rotating, all-composite rigid rotor
The two-bladed rotor, although in better shape dynamically than a single-bladed rotor, must accept very high cyclic loading if a rigid rotor
hub system is employed or provide a so called teeter bearing to allow the rotor blade to rock (as a pair) to alleviate blade, drive train and tower head loading.
Written by a University of Washington professor, this undergraduate chemistry textbook explores the particle in a box, the harmonic oscillator, the rigid rotor
, and the hydrogen atom in depth.
