Innovation
Roxel designs, develops, manufactures and markets a wide range of high-technology defence systems for air, land, sea and space applications.
Thrust modulation
Pulse motors
Pulse motors are the simplest way to achieve thrust modulation. The most popular form of pulse motor is the dual pulse motor. They are very promising candidates for the next generation of missiles.
The key characteristic of the motor is the management of different thrust impulses according to mission needs.
Pulse management is performed by several propellant charges separated by a frangible bulkhead or a soft membrane, where the charges can be ignited separately (consecutively).
Discrete or continuous variable throat
The discrete or continuous variable throat is a recent technology to achieve enhanced thrust modulation.
The key principle is to adjust the thrust to demand in real time by means of a variation of the throat area and consequently of the mass flow which is directly linked to the thrust.
A future version of the continuous variable throat will be used in conjunction with extinguishable propellant in order to add the possibility to stop and restart and thus vary the thrust on demand.
Thrust vectoring
Different technologies for thrust vectoring have been used for decades (jetavator®, jet interceptors, jet vanes, flexible nozzles, etc.).
Recent work aims to reduce manufacturing costs, enlarge the operational temperature range, reduce mass and energy consumption, achieve larger deflection angles, replace hydraulic by electrical actuators, etc.
Divert attitude control system (DACS)
Divert Attitude Control Systems (DACS) are designed to perform the endgame manoeuvre of extremely high-speed missiles used to defeat high-speed threats.
Recent work has the same objectives as previously. Future versions will use advanced energetic materials, innovative temperature-resistant materials (ceramics, etc.) for valves and nozzles.
Soft vertical launch
Soft vertical launch makes use of different technologies like particle-free propellant charge, hot gas valves, etc., to obtain an efficient, small, responsive, safe and reliable device that forms the initial trajectory of surface-launched missiles.
Hybrid propulsion
Roxel is involved in the PERSEUS study, led by the French Space Agency (CNES).
The benefits of this technology, which inherently allows thrust variation by adjusting the fuel and oxidant mass flow rates by means of an injection system, could be useful for tactical applications.
Signature control (stealth)
Roxel propulsion technologies can be used to design motors with optimised characteristics to meet the requirements of missile manufacturers across the entire spectrum (visible, ultra-violet and infrared).
Different propellant formulations are available to comply with the prime requirements concerning the solid rocket motor plume by seeking to reduce or eliminate primary and secondary smoke.
In addition, Roxel is able to adjust the design and select the most appropriate inert materials in order to obtain the stealthiest solution.
Insensitive munitions
Insensitive Munitions (IM) are munitions for which, in the event of physical or mechanical aggressions, the probability of untimely initiation as well as the violence of the reaction and the resulting collateral damages have been reduced. While being safer, IM continue to satisfy performance, availability and employment conditions.
Roxel has a world lead in IM technology and is active in developing positive solutions. Roxel has a proven capability of designing systems to withstand different potential aggressions (bullet impact, cook off, fragment impact, sympathetic detonation, safety drops).
Roxel contributed to the propulsion system for the British ASRAAM missile and the boost motor system for the Seawolf. Both missiles have been put into service. The ASRAAM rocket motor has the highest IM rating for any missile.
Roxel is a member of IMEMG (Insensitive Munitions European Manufacturers Group) and Roxel UK is a member of the MoD’s Joint IM Strategy Group.
Roxel, committed to innovation
Every year, Roxel makes significant investments in innovations for solid rocket motor technologies and in production processes for motors and subassemblies, under an EN9100-certified internal innovation process (collection and evaluation of new ideas, supervision and evaluation of projects).
This work is carried out internally and with numerous partners: SMEs (NIMITECH, etc.), research bodies (CNRS, universities, ONERA, QINETIQ) and major groups (MBDA, ArianeGroup, Nexter, Airbus, etc.).
Part of this work is carried out under the Franco-British Materials and Components for Missiles Innovation and Technology Partnership (MCM ITP), for lower Technology Readiness Levels (TRLs), as well as under upstream study programmes financed by the French defence procurement agency (DGA) and the UK Weapons Science and Technology Centre.
Roxel is also involved in civil aeronautics, e.g. through its participation in an initiative under the French CORAC aerospace research programme in which Roxel, in partnership with NIMITECH, is developing an engine pylon heat exchanger shroud built from an innovative composite material.
Research & technology
Thrust management: ITP
As leader in the solid rocket propulsion sector, Roxel is involved in the Franco-British partnership called MCM ITP (Materials and Components for Missiles Innovation and Technology Partnership). MCM ITP is an advanced research programme self-funded for one half and equally sponsored for the other half by the DGA procurement agency of the French Ministry of Defence and its British equivalent, DSTL (Defence Science and Technology Laboratory).
Its aim is to build up, through transnational innovative solutions, common technology and an industrial base for the development of future European guided weapons.
Roxel has proposed a number of topics and is now studying thrust modulation, thrust orientation and a combination of the foregoing to develop a flexible and agile concept.
Energetic materials
Roxel is involved in research in energetic materials through applied research programmes at the French DGA and the UK MoD’s Weapons Technology Centre.
PERSEUS
The PERSEUS science student space research programme was initiated and is led by the French Space Agency (CNES). This project is looking to spur innovative technical solutions in all areas related to launchers. It is aimed chiefly at students in higher education.
Roxel has been involved in the PERSEUS project since 2006 and has been an industrial partner on the study of hybrid propulsion solutions since 2009. As a recognised expert in propulsion and pyrotechnics, Roxel also counsels the CNES and students on issues related to solid propulsion.
Roxel is in charge of carrying out propulsion systems testing.

We have not, do not and will not compromise on these standards due to our zero tolerance policy that calls for immediate disciplinary sanctions against our stakeholders and employees. Ethics and compliance are part of Roxel’s identity.
To support the continuing strict application of our standards, we have established a Group Business Ethic Committee to monitor the application of our code of ethics and our full set of compliance programmes, to establish a schedule on these subjects, to assess Roxel’s performance with respect to these standards and, if necessary, to implement improvement plans, including an update or the implementation of new dedicated procedures.
This committee includes all members of the Group Executive Committee and reports directly to me. Roxel shareholders are informed about these standards and their implementation.
Furthermore, the success of our standards is ensured by dedicated operational organisation comprising a Group Chief Compliance Officer (a member of the Executive Committee) and local compliance officers.
Compliance officers are in charge of setting the priorities established by the Business Ethic Committee and myself, validated by our shareholders. They also make sure that our procedures are applied at all times and in all places. These procedures cover: risk mapping, management of whistle-blowering, performance of stakeholder verification actions. They have a key role: operational decision-making depends on them.
The compliance officers network is also responsible for employee’s awareness-raising in close coordination with human resources and depending on the category of employee for which the awareness session is adapted. I have also launched an effort to raise stakeholder awareness by preparing a supplier code of conduct and by establishing anti-corruption standards applicable to all Roxel stakeholders.
The success of these standards is also due to an in-house culture of ethics and compliance supported by regular awareness-raising, integration of these standards and procedures into the quality management system accessible to all employees and the possibility of reporting any violation of these standards under the whistleblowering accessible to all employees and stakeholders.
The whistleblowering is supported by the following guarantee: whistle-blower protection; presumption of innocence of the accused person; confidential, impartial investigation; and the accused person’s right to defend themselves.
We have also identified the need for compliance programmes dedicated to specific, complex regulations. In this respect, I have decided to divide our ethics policy into specific compliance programmes:
• Corporate social responsibility
• Anti-corruption compliance programme
• Export/import control and international economic sanctions compliance programme
• Personal data collection and processing compliance programme
• Competition law compliance programme
The respect of our ethics policy and compliance programmes involves all our employees and stakeholders who are responsible for ensuring that they are respected and promoted. This is the best way to achieve excellence in our performance.
