EHP on board Juice

Euro Heat Pipes work is quoted in the newspaper “l’Echo” in an article dedicated to the space probe JUICE (JUpiter ICy moons Explorer) which will explore the icy moons of Jupiter named Ganymede, Europa and Callisto.

We can be proud of our contribution to this space probe JUICE which is noteworthy in many ways:

  • This is the first time that an European probe will go so far in the solar sytem
  • Beyond providing the heat pipes for the probe, we have also performed dedicated studies & trials to assess the impact of the radiations (much harsher around Jupiter) on our products.
  • This probe will leave Earth in 2023 and will make an incredible trip to reach Jupiter:
    • After leaving Earth,
    • it will pass by Venus in 2025
    • will come back close to Earth in 2026
    • will go beyond Mars …
    • but will come back close to Earth, one more time, in 2029
    • and will finally reach Jupiter moons in 2031

Why such a complicated journey ?

A tremendous amount of energy is required to reach the outer solar system. In order to cap the fuel quantity onboard, the probe will make several gravity-assist maneuvers (also called swing-by): by entering and leaving the gravitational sphere of influence of a planet, which is orbiting around the Sun, the probe will be able to accelerate (and also to change direction) with no fuel consumption.

Subsidiary at 51% of Airbus since 2017, Euro Heat Pipes (EHP) company, based in Nivelles (Belgium), has delivered a set of 27 heat pipes (thermal control systems for spacecraft) which allow the transfer of the excess heat to cold areas of the spacecraft.

Heat Pipes Development, Qualification and Industrialisation

EHP has completed its major TELECOM ARTES 4.0 project with ESA funds.

Objectives

The 3 mains goals of this ESA & EHP co-funded project are:

  • Achieve a major increase in terms of EHP heat pipes production capacity 
  • Achieve a major decrease in terms of EHP heat pipes production cost
  • Develop & qualify a new heat pipe product (AG128) for OneWeb project

Challenges

Although heat pipes are well-known products at EHP since decades, its industrialisation (reliable and stable production of large volumes) remained undeveloped.

Improvement of manufacturing processes efficiency and beat rates were challenges.

Benefits

Thanks to the increase of production during the last years, EHP is in a very good situation to propose products with a demonstrated reliability, produced within an existing production line, whose capacity has been demonstrated.

Features

Heat pipes allow to transport a significant amount of heat (typically 100 Watts) over a significant length (typically a few meters), within a negligible thermal gradient (typically a few degrees); which is thousands of times more efficient than thermal straps. 

Example of a heat pipe batch during manufacturing

They are also very reliable as they have no moving parts, which is key for space industry.

System Architecture

Heat pipes are used at spacecraft level for their thermal control. They are mounted on panels or embedded into panels.Plan

Plan

Several phases of industrialization were defined and deployed within EHP workshop in order to implement gradually the updates.Current status

Current Status

Project is successfully completed.

This huge increase of the EHP deliveries transformed EHP into a major worldwide space heat pipes manufacturer.

This also permitted EHP:

  • To extend its marketshare in traditional sectors (European SatCom)
  • To reach new markets (US satellite manufacturers)

From a socio-economic point of view, deployed production line creates 11 full-time jobs at EHP (+ indirect jobs e.g. subco level)

Beyond the scope of this ESA project

Over the years, EHP has grown from a small 600m² facility to working areas spread over 3 buildings for a total of 4500m².
This is not enough for the activities forecasted in the next years With the major OneSat project arriving, and with our heat pipe production continuing to grow, EHP needs much more space.

In 2019, the idea of a new modern building was put on the table. Two years later, in May 2021, the work of a brand new 10 000m² facility has begun

New infrastructure consists of 8000m² of industrial areas, including a 2000m² clean room for the assembly of our thermal and deployable systems. Additionally, it includes a nice 2000m² office building that will offer a well-being working environment to all of us.

The first part of the project, the industrial hall and half of the clean room, are to be delivered in the beginning of 2022. The offices and the rest of the clean room are to be available 6 months later, and the final industrial areas for machining and logistics in the beginning of 2023.

What:

OneWeb, the Low Earth Orbit (LEO) satellite communications company, will launch 36 satellites (EHP Heat Pipes onboard) on Thursday, 1 July 2021, marking the completion of its ‘Five to 50’ ambition enabling connectivity services for the first time to the 50th parallel and above by the year end.

Each of these satellites includes a set of several heat pipes manufactured by Euro Heat Pipes in Belgium. This new launch will bring the total number of in-flight satellites to 254.

Service demonstrations will begin this summer in several key locations – including Alaska and Canada – as OneWeb prepares for full commercial service in these regions in the next six months. Offering enterprise grade connectivity services, the company has already announced distribution partnerships across several industries including with ROCK Networks, AST Group, PDI, Alaska Communications and others, as OneWeb expands its global capabilities. The company continues to engage with telecommunications providers, ISPs, governments and more worldwide to offer its low latency, high speed connectivity services and sees growing demand for new connectivity services to connect the hardest to reach places.

Why:

This launch adds another 36 satellites to OneWeb’s 648 LEO satellite fleet that will deliver global connectivity and represents 100 percent of the satellites required to enable its solution to reach all regions north of 50 degrees latitude.

This launch will enable OneWeb to offer full connectivity services across the United Kingdom, Alaska, Northern Europe, Greenland, Iceland, continental U.S., the Arctic Seas and Canada. Commercial service is expected to be rolled out before the end of the year, and OneWeb intends to make global service available in 2022.

To mark the fifth and final launch of ‘Five to 50’, with all satellites delivered on time, a welcome message “Hello North Pole” is branded on the rocket, reflecting the significant progress OneWeb has made to secure its Arctic coverage.

EHP Heat Pipes on CAS500

Source: https://www.kari.re.kr/eng/sub03_02_03.do#link

KARI is developing the CAS500-1 system, to meet the public needs for satellite images efficiently, to expand the domestic satellite industrial base, to cultivate related industry, and to promote satellite exports.

CAS500 satellite

CAS500 series will adopt the medium-sized standard platform which will be developed for the CAS500-1 system. It will save the time and cost for the development considerably. And domestically developed payloads, such as electro-optical cameras, microwave probes and hyper-spectral imager will be installed on the standard platform.

CAS500 program is divided into phase I and phase II. In phase I, 500kg class standard platform will be developed. And two 0.5m resolution electro-optical satellites (CAS500-1 and CAS500-2) will be developed by using that platform.

While developing the CAS500-1 system, KARI will transfer the satellite technologies accumulated over the years to the domestic industry and the CAS500-2 whose specification is identical to that of CAS500-1, will be developed by domestic industry.

The CAS500-1 will be launched in 2019 and CAS500-2 in 2020.

The CAS500 can be easily commercialized as it can be developed in a relatively short period of time at a low cost compared to medium to large sized commercial satellite. In addition to that, by developing multiple satellites in a short time and operating them simultaneously, it will help satisfy various public needs for earth observation and reduce the observation interval.

EHP has been selected by i3system, Inc. (http://www.i3system.com/eng/index.html) to provide the heat pipes (AG060) for the thermal regulation of the Focal Plane Assembly (FPA).

EHP heat-pipes on Aeolus European satellite

Equipped with a high precision laser, this high-tech machine must allow a serious leap forward in weather forecasts, but also in climate science.

The small Vega launch is preparing to launch this Tuesday from Kourou, French Guiana, the European satellite Aeolus, a high-tech machine designed to measure wind worldwide as part of the Copernicus Earth Observation Program to measure winds from space, Aeolus will experiment with a whole new technology based on a high-performance laser (Lidar for Light Detection and Ranging), that will distinguish the lower layers of Earth’s atmosphere (up to 30km height) to produce vertical wind profiles and gather information about aerosols and clouds. This revolutionary instrument, called Aladin (Atmospheric LAser Doppler Instrument), demanded more than 6 years of development and is equipped with a HP thermal BUS, developped by EHP with the support of Airbus DS NL, that enables an optimised thermal control of the LIDAR.

Today’s daily weather forecasts already contain wind information, including probe balloons and field probes. However, the direct measurements are too fragmentary. Scientists and meteorologists need accurate data on the winds periodically to understand the systems that affect weather and climate and improve their forecasts.

Aeolus will be the first satellite to provide them with this information. The prestigious NASA had developed an instrument based on the same technology for its ICEsat satellite.

The information thus collected will make “not only a serious leap forward in the weather forecasts, but also contribute to long-term climate research”,

A subsidiary of Airbus

The satellite was built by Airbus Defense and Space. A Belgian subsidiary of Airbus, the company EHP, established in Nivelles, was involved in the project. Earlier spin-off of ULB and Sabca, EHP (Euro Heat Pipes) specializes in thermal space control space technology. It provides thermal control equipments based on two-phase heat transfer principles.

Aeolus is part of the European Union Copernicus Program. Copernicus’s ambition is to create a system for monitoring and understanding the environment similar to those found for meteorology. The program includes 6 satellite families (radar image, optical, altimetry, chemical analysis, etc.) dedicated to observing land and sea, as well as monitoring the composition of the atmosphere.

This European Earth observation program will generate a phenomenal amount of environmental data. Due to its long-term character, Copernicus must allow the development of downstream services, which the current scientific satellites do not allow.

Airbus Defense and Space, a subsidiary of the Airbus group, has become the majority shareholder (51%) of Euro Heat Pipes (EHP).

This is a spin-off of the French-speaking Free University of Brussels (ULB). This was announced on Monday by Theodorus, the ULB investment fund. The Walloon region now holds 49% via SRIW (the Regional Investment Company of Wallonia) and Sogepa (the French state-owned body investing in European aerospace).

EHP was born of the collaboration, initiated in 2001, of the Faculty of Applied Sciences in ULB, and Sabca (the Belgian aeronautical construction company) to create a laboratory, unique of its kind, based upon microgravity in space. The aim was to create systems and innovations for aeroplane temperature monitoring.

The technology developed by the spin-off involves a cooling system, without using air or any of the aeroplane’s engines. It extracts the heat at source, carries it away and discharges it. The on-board electronic equipment is thus better protected owing to a lower constant temperature. The company says that the reliability of all of the aeroplane’s engines is thus optimised. It further adds that the process is particularly efficient in extreme conditions.

To design, produce and market its inventions, EHP has benefited from the financial support of Theodorus. The investment funds of ULB have acquired 50% of the capital from the spin-off. To enable the project to grow, Airbus acquired an interest in the business, with a shareholding of 16% in 2008. This share will now grow to a total of 51%.

In a few years, the turnover has gone from €2 million to €8 million and the company, based in Nivelles, now employs some 70 employees.

SES-12 launch

SES-12 equipped with two P-DPS made in EHP was successfully launched to a Geostationary Transfer Orbit (GTO) on Monday, June 4, 2018 from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station, Florida.

Liftoff occurred at 12:45 a.m. EDT. The SES-12 satellite was deployed about 32 minutes after liftoff.

The DPS arms are clearly visible throughout the live launch stream.
