Thermocoax’ applications set on satellites dedicated for space debris clean up !

The 22nd of March, 2021 at 06:07am (UTC), GK Launch Services has launched Soyuz 2.1 rocket from Baikonur Cosmodrome.

The launcher has deployed a Fregat upper stage in space, and fired its engine several times over four hours to inject 38 small and medium-size international satellites into three different orbits.

On these 38 satellites, two of them are equipped with THERMOCOAX heating systems dedicated to activate the chemical propulsion.

One of the satellites is dedicated for space debris clean up. The other one is dedicated for imagery with electro-optical sensor in it for earth observation.

These heating systems are designed, developed and produced in our factory of Normandy, France. THERMOCOAX has 15 years heritage. Most of the application are:

  • Catalyst Bed heater for chemical propulsion
  • Magnetic coils and high temperature cabling for electrical propulsion
  • Rod heater for payload temperature control (Mechanical Pump loop )
  • Heating coils for actuators based on SMA technology (pyrotechnic free)THERMOCOAX success is based on the motivation and passion of his all employees plus of course, on the unic home made mineral insulated cable.

The cable offers small dimensions, flexibility, ability to withstand 1000°C and more with exotic material.

This technology has already demonstrated 15 years on board GEOSatcom with more than 15 000 devices.

THERMOCOAX is currently travelling on March with Curiosity for dust samples treatment and will be soon again with EXOMARS program on the landing propulsion system.

THERMOCOAX is pushing its technology on chemical propulsion to make it more efficient and proposes innovative solutions for the electrical propulsion. Some last developments are under qualification and dedicated for the thermal management of high energy intensive 100 volts plateforms.

Two satellites are equipped with catalyst bed heater systems for chemical propulsions.

Since more than 10 years, THERMOCOAX is supplying innovative heating systems for the chemical propulsion, green and hydrazine.

More than 200 catalyst bed heaters are flying currently successfully.

These propulsions are used several times per day for altitude, trajectory and orbit control.

New designs of catalyst bed heater with fast heating ramp-up are now qualified and aim debris avoidance and under demonstration for debris removal mission.

Environment

THERMOCOAX, part of the new space propulsion technology of the key occidental Geosatellite makers.

THERMOCOAX equips with magnetic coils and heating systems to make the platform more reliable and 25 years service life.

The Challenge

Space platform request magnetic coils to produce the thruster of the engine to travel to final orbit and then keep the satellite on the orbit during all his life.

The customer system was looking for component withstand high temperature and long reliability (25 years).

Heating system is used to avoid the engine to rech too low temperature. By this, the engines are fully operational at full power when activated.

These systems need to be fully proven by strict tests and qualifications program. Heavy document have to be provide for a full traceability of the components and production.

The Solution

Based on our homemade mineral insulated cable and our high level of engineering, production and quality management, we design and produce dedicated final systems ready to be mounted on the propulsion system.

 

Choosing electrical propulsion increases the service life of the satellite, means more value for the OEM and more service for the satellite operator.

In pratice, electrical propulsion saves 10 to 15% of volume replaced by payload used for datas that the operator sell to his customers.

Gender equality Index at THERMOCOAX

As of 1 March 2020, companies with between 50 and 250 employees are required to calculate a gender equality index to evaluate whether they are taking appropriate action towards gender equality.

This figure is a measure of equal pay for men and women in the world of work, applying the principle of “equal pay for equal work”.

This index takes the form of a score out of 100 and is based on 4 criteria:

  • No pay gap between women and men with the same role and of a similar age,
  • Equal opportunities for a pay rise,
  • The number of employees who received a pay rise upon returning from maternity leave,
  • At least four women in the ten highest paid positions.

For the year 2019, THERMOCOAX scored 76/100.

This performance demonstrates the company’s commitment to diversity and equality and, as always, pushes us to continue to improve on this score in the future.

Nuclear fusion

1.    FUSION: Advantages and CO2 reduction in energy production.

Fusion is a physical principle during which two nuclei combine to generate energy.

For a peaceful application, electricity would be generated through a reactor generating heat, which would then be transferred in a loop to activate a turbine.

There would be numerous advantages of this technology: CO2 free electricity production, minimal waste compared to FISSION reactors, unlimited “raw material” coming from the sea and intrinsic safety. If problems occur, switch off the reactor.

2.    Basic principle

Fusion is the process that occurs in the core of the Sun and stars. When we see light and feel warmth, this is the result of fusion reactions: hydrogen nuclei collide, fuse into heavier helium atoms and release considerable amounts of energy in the process. Fusion is the main source of life in the Universe. To reach an appropriate environmental condition at which the reaction can occur, different vacuum chambers have been developed with Tokamak reactors.

3.    TOKAMAK reactors

A Tokamak reactor is a vessel which uses a strong magnetic field to contain a plasma and ultimately produce a net energy output. It is shaped like a “donut”.

Tokamak stands for the Russian acronym of toroidal chamber with magnetic coils. This scientific device was initially conceptualised in the 1950s in Russia and built in several countries in the 1970s. The most powerful of them being built in UK, the Joint European Torus (JET).

In the 1980s the idea of an international project called ITER (International Thermonuclear Experimental Reactor) was proposed by Russia to the USA.

4.    ITER

ITER (“The Way” in Latin) is designed to demonstrate the scientific and technological feasibility of fusion energy. ITER is a large-scale scientific experiment that aims to demonstrate the possibility of producing commercial energy from fusion. It is the culmination of sixty years of fusion research, carried out on hundreds of devices all over the world.

ITER is also a unique international collaboration bringing together China, the European Union, India, Japan, Korea, Russia and the United States – seven Members (35 nations).

The ITER Members have a shared responsibility to design, build and operate the ITER installation. Following the establishment of the ITER Organisation and a preparatory site, a unanimous decision was made in 2005 whereby the ITER Members chose a site in the South of France suggested by the European Union.

  • A giant device weighing 23,000 tonnes. A fusion energy generating 500 MW of output power.
  • The World’s largest vacuum vessel, heavier than the Eiffel tower.
  • A plasma temperature of 150 million °C, x 10 the core temperature of the sun.
  • And when less than 10 metres away, there is a magnet temperature of -269°C (4K°).

5.   ALTERNATIVE TECHNOLOGIES

Nowadays multiple initiatives are receiving funding. Some new projects have been launched in the US, in the UK and in China. Plasma is a question of density. To increase plasma density and release more energy than  required in order to initiate the plasma, some compression techniques are combined to magnetic confinement. The future reactor will be more compact, simpler, more stable and cheaper.

6.    THERMOCOAX INVOLVEMENT

THERMOCOAX fully supports FUSION technology. Over the years and through projects like JET, we have accumulated experience and developed specific solutions for the FUSION reactor.

THERMOCOAX technology -Mineral Insulated cable- is ideal for harsh environments with fluctuating temperatures, high levels of radiation, a high vacuum or a high magnetic field.

THX can offer solutions such as:

CABLING: In-vessel cabling, penetration feedthrough

SENSORS: Temperature and magnetic field measurement

HEATING: Backing of small items or massive pieces of steel forming the vacuum vessel

Our integrated nuclear department (engineering, qualification, quality assurance, production) coordinated by our project department develops bespoke solutions, in which norms and regulations play a critical role.
