This paper revisits the notorious Dean’s drive, aiming at causing unidirectional motion when attached to an object at rest (inertial propulsion). Instead of the usual circular path along which lumped eccentric masses move, a novel figure-eight-shaped curve is proposed. It is generally shown that the rotational kinetic energy accumulated in the rotating masses produces an equivalent linear ‘initial’ velocity to the object, and therefore, it further works like an oscillating projectile within the…

Inertial propulsion Part III : A note on Laithwaite ’ s engine
In this paper, using Newtonian mechanics, we show that under the assumption of small motion about the horizontal plane, the famous Laithwaite’s engine operates like an ideal harmonic oscillator. It


A study of the mechanics of an oscillating mechanism
This paper discusses aspects of the mechanics involved in the Dean-like Space Drives, which are mechanisms with two eccentric lumped masses that rotate in opposite direction about parallel linear
A Device that can Produce Net Impulse Using Rotating Masses
This paper describes a device capable of producing net impulse, through two synchronized masses, which move along a figure-eight-shaped orbit. In addition to the detailed description of the
Support forces in a synchronized rotating spring-mass system and its electromagnetic equivalent
This paper deals with the dynamic analysis for the calculation of the support forces in a rotating elastic rod when subjected to simple types of axial forces. For simplicity the model starts with a
