Electrodynamic Tether Technology for Passive Consumable-less Deorbit Kit

Deliverables

Coated LWTs will be tested in the vacuum chamber to determine the work function in addition to optical tests mechanical tests traction and fatigue thermal cycling Atomic Oxygen and Ultraviolet radiation A bulk measurement will serve as a reference for the LWTs

DK Target Requirements

DeOrbit Kit Target Requirement document with justification Document includes functional performance operational and verification requirements

LWT Mission Design

Document describing the algorithms to make optimal mission design with LWTs In particular the algorithms provide the optimal tether geometry shape and dimensions It considers both deorbit and reboost missions and the corresponding figures of merit such as system mass deorbit time system efficiency tether cut probability etc The algorithms will be used to calculate the optimal performance of LWT in the two scenarios as a function of the physical properties of the LWT

DM Baseline Design

The report illustrates the results of the tradeoff analysis among different mechanical solutions the preliminary definition of requirements and presents the deployment mechanism baseline concept

Powder Synthesis and First paste

Two synthesis routes for the C12A7-base material (solid state reaction and glass ceramic route, both including doping for enhanced photoelectron emission) and a thermal treatment for the transformation into the electrid C12A7:e- will be developed in order to provide a processable powder quality. Sintered hollow cathodes made of C12A7:e powder will be manufactured and available for characterization of photoelectron behavior (TUD) as well as for the development and qualification of suitable adhesive brazing pastes. First composite pastes based on C12A7:e- powder and brazing alloy powders will be available and characterized ready for coating experiments on metal foils on LWT by screen printing processes (20x20mm2).

LWT Model and Target Requirements

Document with a detailed description of the LWT/plasma model for round and tape tether geometries. Precise list of the target requirements, i.e. the optical, mechanical and thermal properties that the LWT should satisfy to meet the performance in deorbit and re-boost missions.

Project Website

Public website with information about the space debris problem, the tether solution and the goals of E.T.PACK. It also includes information about the partners and their roles in the development of the deorbit kit. The website will be updated periodically with the publications list, presentations in international conferences, and main results, including simulation data.

Data Management Plan

Management plan of the data that will be generated in E.T.PACK. It will be mainly focussed on the numerical data generated on emissive Langmuir probes and its application in flight simulator of low work function tethers.
