In-line Damper for Space Application
This patented In-Line Damper aims to provide energy dissipation from a tether, to reduce oscillations and improve dynamical stability, particularly for a conductive tape/tether for space applications.
The device is intended for use on satellites and in particular in deorbiting devices for satellites in low earth orbits (LEO). These devices are based on electrodynamic cables or tapes that provide by interaction with the magnetic field an opposing Lorentz (electrodynamic) force on motion to lower the orbital height until atmospheric reentry in compliance with the guidelines for mitigation of human-produced orbital debris.
Current TRL is 4-5. Further financing for upscaling will bring TRL to 7-8.
