Pyrotechnics and fireworks
Pyrotechnics is used in several applications, such as fireworks, airbags for cars, infrared flares for military vehicles and igniters for rocket motors and ammunitions. TNO has the knowledge for both...
Defence laboratories are always searching for new, less sensitive and more powerful propellants. Propelling a projectile at high velocity is, however, not the only requirement. The use of high-energy gun propellants with armour-piecing projectiles, for instance, also leads to extensive barrel erosion. The use of Triple Base Propellants - in naval guns - does reduce both barrel erosion and the muzzle flash, but at the same time has an adverse effect on velocity. An ideal gun propellant shows a good balance between all the necessary characteristics. At TNO we have been researching and testing gun propellants for more than 40 years.
The expertise gained by TNO in gun propellants is used in both support and product development. TNO supports Defence in all kinds of issues related to gun propellant-based weapon systems, including e.g. new developments, service munitions and life extension. TNO also designs and develops charge concepts, ignition systems and small to medium - up to 1000 kg - batches of propellants. Finally, TNO is able to assist in the optimisation of gun propellant production methods. Our extended facilities for Modelling & Testing offer the guarantee that Defence, the principal user of gun propellants, will always have a good insight into all their characteristics, such as chemistry, ballistics, rheology and extrusion.
