Facebook Twitter Share Proven competencies To aim at perfection Integrated propulsion systems A rocket motor is mainly composed of: • A motor body, which is generally part of the external structure of the rocket or missile • A set of insulations protecting the case from thermal and/or chemical aggressions • A propellant grain • Blast tubes and nozzles with or without jet deflectors (flexible stop, jet deflector unit) • An ignition device • In some cases the rocket motor also includes other components such as an Igniter Safety Device (ISD), external thermal insulation, hangers, etc. Roxel offers a very wide range of propellants and motor cases plus associated materials: • Energetic materials: propellants (EDB, CDB, composite, nitramite) • Manufacturing technologies for rocket motor structures Inert materials Roxel, designs, develops and manufactures a wide range of inert materials. They are used to protect the structures and to inhibit the propellant grain where needed. These materials must possess: • Resistance to thermal shock and high temperatures • Ability to reduce thermal transfers to the case (low thermal conductivity) • Resistance to mechanical shock linked to initiation • Resistance to chemical and mechanical erosion linked to combustion gases • Chemical compatibility with propellant grain and propellant gas • Lowest possible density Inert materials can be classified under the following component families: • Elastomeric materials, such as silicones and rubbers (applications: thermal insulators, ablative protections for short duration systems, flexible thrust nozzles, inhibitors, glues, etc.) • Rigid materials using phenolic resins, etc. (applications: thermal insulation applied for combustion chamber reinforcement, pipes, heads, ramjet nozzles and cases, intumescent paints, etc.) • Ceramic and composite materials (applications: TVC (thrust vector control) components such as nozzles, valves, jet vanes, etc.) • Refractory materials, such as molybdenum (applications: nozzles, jet tabs, etc.) Structures Roxel, through its versatile panel of in-house casing production technologies, can design and propose the best compromise (cost, performance, IM properties) to fulfil the customer’s requirements. Motor assembly Roxel is not only an expert in the core elements of a rocket motor (energetic materials, structures, inert materials), but is also an assembler and integrator. Thus, based on customer specifications (thrust, weight, sizing and requirements for assembly within the missile) Roxel can conceive, design and produce the propulsion system.
