MODEL FOR A GYROSCOPE WITH INNER ROTORS CONNECTED AT 120 0

Abstract

This paper is conceived as a follow up of the paper Model of a Dynamically Tuned Gyroscope. It deals with creating this time a model for a dynamically tuned gyroscope with inner rotors connected at 1200. Before generating the model it seemed interesting to also create a representation of the instantaneous axis of rotation motion, as we know the gyroscope has a fixed point motion. The representation shows different postions of the axis during the gyroscopic motion, using again the Mathcad programme. Then, the model at rest was represented and after introducing the matrix of the rotation angles, we obtain the changed positions of the inner rotors and of the torsion bars, for two different situations. The transducers equipping the inner rotors will transmit the information to the gyroscopic device they are serving and it is easier and cheaper to check their functionality using virtual models on the computer, before the device is assembled on the aircraft.
