Flight Qualification of Deployable Radiator using two phase technology


Pegasus is a project of the EU Horizon 2020 Programme
1. Increase the maturity of thermal management components

The proposed DPR represents a unique technology, an evolution of loop heat pipes with enhanced thermal dissipation. The DPR qualification provides a key contribution to plans for improving European space platform capacities.

2. Qualify a European supplier for space critical technologies

PEGASUS project goes a step forward catching the DPR technology manufactured in Europe and addressing its validation for LEO and GEO platforms. The outputs of the project will guarantee a European DPR product fully qualified for next flight mission.

3. Integrate a European supply chain

PEGASUS project is structured in a building block approach. The project integrates end users and platform manufacturers with components manufacturers, design offices and test centers. The project opens a supply chain for both telecom and earth observation future platforms.

4. Promote the number of Small Companies in space activities

In PEGASUS consortium there are two small companies: IberEspacio and ActiveSpace. The complementary competences of these small companies allow to offer a complete subsystem to end users.

5. Provide validated space technologies for spin-off in non-space sectors

The new materials technologies developed under PEGASUS proposal could be transferred to non-space users. The use of alodine-Cr free technology is a spin-in approach, but the results of evolution and validation for space use could extend the applications.

6. Develop a commercial evaluation of the technology and address how to access the market

The business plan for the exploitation of the results of the project consists in the detailed market analysis in order to define key clients in each country related with the aerospace sector and non-space industry as well.


Flight Qualification of Deployable Radiator

Pegasus is a project of the EU Horizon 2020 Programme, focused on the Activity COMPET-1-2014 “Technologies for European non-dependence and competitiveness”.

The increasing demand of power rejection in present and future satellites, mainly for telecommunication applications, requires the development of deployable radiator panels which can be stowed for launch and then deployed once the satellite is on its orbit.

In particular, in the case of the full electric propulsion systems for new telecom platforms, the need of deployable radiators to cover the main communications panels (north-south) during the orbit raising time (up to 180 days) is the most common baseline design demanded by the telecom satellite manufacturers.

Once in nominal operation orbit, such deployable radiators are used to provide the corresponding extra heat rejection capability of the satellite and therefore to increase payload transponders amount and type.


The project partners constitute a reliable supply chain capable of achieving the project objectives. The consortium is well balanced and integrated at European level (Spain, France, Italy, Portugal), which is a need for satellite platform manufacturing.
Coordinator of the project and responsible of the design, manufacturing and testing of the DPR.
In charge of the system specification issuing for telecom and LEO applications. Ensuring all along the project the consistency between the system needs and the DPR development. Design, manufacturing and testing to demonstrate the scalability, flexibility and adaptability of the design.
Responsible for the design, manufacturing, assembly and testing of the DPR Deployment Mechanism for Development and Qualification model.
Responsible for the structural modeling and manufacturing of the machined parts of the DPR QM and the prototypes.
In charge of the new materials development, in particular the replacement of the chromium-based coatings currently used in the DPR by alternative chromium-free surface treatments and coatings.
