An anomalous propulsion mechanism

Spacecraft Electric Propulsion—An Overview

A short review of the status of electric propulsion (EP) is presented to serve as an introduction to the more specialized technical papers also appearing in this Special Issue (Journal of Propulsion and Power, Vol. 14, No. 5, Sept. –Oct. 1998). The principles of operation and the several types of thrusters that are either operational or in advanced development are discussed Ž rst, followed by s...

Control of a propulsion mechanism over a wireless network

This paper investigates the implementation of a pendulum-driven cart-pole system through wireless networks. The system is underactuated since the only control input is the motor which drives the pendulum movement while the cart has free movement wheels. An onboard client PC controls the torque to the motor, whilst a host PC monitors progress and controls the demand to the motor. The two PCs hav...

A Mechanism of Action for Shawyer emdrive Propulsion System

Mott Mechanism and Anomalous Charmonium Suppression

We investigate a scenario where conditions for Mott dissociation of charmonium are fulfilled locally in ultrarelativistic heavy ion collisions at the short time scales before hadronization and study possible consequences to be drawn from observation of “anomalous” thresholds in the J/ψ suppression pattern. We suggest that for a compilation of experiments with different kinematics, variables pre...

A new concept and design aspects of an ‘antigravity’ propulsion mechanism based on inertial forces

a = index referring to the lumped mass ‘a’ b = index referring to the lumped mass ‘b’ Fxi = X component of the inertial force acting on the i-th lumped mass (i = a or b) Fyi = Y component of the inertial force acting on the i-th lumped mass (i = a or b) Fzi = Z component of the inertial force acting on the i-th lumped mass (i = a or b) R = half of the distance between the two arms (bars) in par...
