<p>The invention relates to a plastic propelling nozzle to be used in rockets, characterised in that the nozzle is made from a plastic material with glass fibre injection, that has characteristic properties allowing the entire rocket ignition and firing process to be carried out successfully without presenting the problem of the nozzle melting or being damaged due to the launching heat. The nozzle made from a plastic material is advantageous in terms of weight reduction, which allows the rocket longer flight autonomy and a more reliable flight, as it displaces the pressure centre of the rocket, improving the aerodynamics thereof, which also allows the payload of the rocket, i.e. the warhead, to be increased, without reducing the flight distance.</p> |
