Title: Innovations of James H Andrus
Introduction
James H Andrus is a notable inventor based in Glendale, AZ. He has made significant contributions to the field of aerospace engineering, particularly in the development of advanced control systems for small satellites. With a total of 2 patents, his work showcases innovative solutions that enhance the functionality and efficiency of spacecraft.
Latest Patents
One of his latest patents is focused on a control moment gyroscope based momentum control system for small satellites. This self-contained momentum control system (MCS) features a miniaturized gyroscopic rotor that operates at a rotational speed exceeding 20,000 RPM. The MCS includes at least three control moment gyroscopic mechanical assemblies (CMAs) that are rigidly mounted within a single enclosure. Each CMA is oriented either orthogonally to the others or parallel but in opposite orientations. To minimize the size of the MCS, an electronics package is integrated within the enclosure to manage command and control signals and provide power to the CMAs. Additionally, shock isolation devices secure each CMA to the enclosure, reducing launch loads and allowing for smaller rotor spin bearings. The entire MCS enclosure is hermetically sealed to protect the components.
Another significant patent by Andrus involves an electromagnetic actuator equipped with a sensor to measure the applied force. This actuator maintains an adjustable force by varying the current in its coils. It consists of an armature and a stator, with the stator featuring a U-shaped back iron that houses two coils. These coils create a magnetic flux path, and sensor units mounted on the pole faces of the back iron measure the flux densities. The output voltage from the sensors is directly proportional to the force, which correlates with the square of the flux density.
