DZH DYNAMICS

scroll

Since 2019 our research group is working on the development of the next generation of Attitude Determination and Control Systems (ADCS), combining the Dzhanibekov’s effect with current existing technology.
By controlling this phenomena, our technology enables the satellite to perform FAST attitude change manoeuvers with LESS energy consumption, while being stable. This new agility will change satellite operations from the Earth Observation to the communication broadcast.  For more information "click here"

Our projects 

EUROPEAN SPACE AGENCY - FLY YOUR THESIS 

DZH Dynamics has been selected for the European Space Agency The Fly Your Thesis! ( ESA-FYT) programme. The parabolic flight campaign takes place on the Airbus A310 Zero-G, which is operated by Novespace from Bordeaux, France. Each campaign consists of a series of three flights of 31 parabolas, which individually provide about 22 seconds of microgravity. Each campaign is a once in a lifetime opportunity  for the students to propose, design, build, test and fly their scientific experiment or technology research in microgravity conditions. The experiments can be related to the fluid physics, chemistry ,biology, material science, astrophysics, etc.

DZH ZG ESA V2 Prototype

DZH ZG ESA V2 prototype contains an inertia morphing (IM) strategy of two moving masses, acting symmetrically in the structure, and a 3-axis attitude control system using Reaction Wheels (RWs). 
DZH ZG ESA V2 Prototype triggers the DZH effect with a period of less than 4 seconds to be within the constraints of the parabolic flight of ESA-FYT using RWs for faster manoeuvres and less energy consumption.

DZH Nanostar Project

DZH Dynamics has  also been selected for the interuniversity challenge NanoStar. There, teams from different universities develop a space mission where innovative ideas boost the performance of state-of-the-art space technologies. Using the Dzhanibekov effect in combination with Reaction Wheels, DZH Dynamics is working in the development of transformable spacecraft which can benefit from a faster and more energy efficient Attitude Control System (ADCS). In order to test this technology before going to space, DZH Dynamics is collaborating within the NanoStar framework with UC3M and UPM-IDR institute (Instituto Ignacio DaRiva). There, the proof of concept of 1CubeSat Unit Spacecraft using our latest technology is tested in their air bearing facilities, so as to validate the research and algorithms of the ADCS.
