“…The topic of rigid body motion is considered one of the important topics in classical theoretical mechanics. It emerged as a clear topic after work by many distinguished scientists [1][2][3][4][5][6][7][8][9], in which the rotational motion of a rigid body about one of its fixed points is transformed into quadratures in three well-known cases, the Euler-Poinsot, Lagrange-Poisson and Kovalevskya cases, when the body moves in a uniform field. There are another two associated cases when the body moves under the action of a Newtonian field, known as generalizations of the Euler-Poinsot and Lagrange-Poisson cases.…”

“…There are another two associated cases when the body moves under the action of a Newtonian field, known as generalizations of the Euler-Poinsot and Lagrange-Poisson cases. These cases assume some conditions on the coordinates of the centre of mass and on the principal moments of inertia of the body [3][4][5]. To accomplish the solution of this problem in full generality, we need an additional fourth first integral.…”
The aim of this article is to study the possibility of obtaining the fourth integral for the motion of a rigid body about a fixed point in the presence of a gyrostatic moment vector. This problem is governed by a system consisting of six nonlinear differential equations from first order, as well as three first integrals. A most important condition for a function F, depending on all the body variables, to be that integral is presented. This work can be considered a mainstreaming of previous works. The importance of this work lies in several applications of the rigid body problem and gyroscopic motion in different areas, such as physics, engineering and industrial applications, for example, in aircraft specially designed to use the auto-pilot function, calculating aircraft turns about various axes of operation (pitch, yaw and roll), and maintaining aircraft orientation.

“…By analogy with [16], we find that the yet unspecified directions of the horizontal axes Oξ and Oη can be chosen in such a way that the components of the fixed hodograph depend on ω 1 , ω 2 , and ω 3 as follows:…”
Section: Hodograph Of the Angular Velocity ωmentioning
Several families of isoconic motions of a heavy nonautonomous gyrostat with a fixed point are analyzed. Assuming that the conditions for the existence of a generalized Steklov solution are satisfied, we indicate the explicit time dependence of the main variables and analytically study the fixed hodographs of the angular velocity ω, the total angular momentum K of the system, and the center of mass position vector. The time dependence of the angle between K and ω is written out and examined. We obtain restrictions on the values of the nutation and proper rotation angles.
