Product Description
High temperature resistant graphite rocket nozzle - an important component used in extreme environments.
Graphite nozzles play an important role in the flames of rocket engines. It is a carbon element that can withstand the impact of high-temperature gas above 3000℃, which is closely related to its many characteristics.
The unique performance of graphite nozzles is mainly reflected in the following aspects:
1. Anti-ablation: The melting point of graphite is as high as 3650℃. The graphite nozzles produced by it do not melt at high temperatures, and the reaction rate with combustion products is extremely low, thus avoiding the nozzles from being ablated and perforated by high-speed gas.
2. Thermal shock resistance: During the rocket eruption, the temperature experiences room temperature to ultra-high temperature. The thermal expansion coefficient of the graphite nozzle is low. During this process, it will hardly crack and is suitable for repeated engine start-stop.
3. Self-lubricating heat conduction: The internal layered structure of graphite can accelerate heat dissipation and avoid local overheating. The graphite powder that falls off during this process can temporarily lubricate the gas flow channel and reduce turbulent friction.
Its series of characteristics make it widely used, mainly as follows:
1. High-temperature gas guidance: In solid rocket engines, graphite nozzles collide with each other in the inner cavity to accelerate high-temperature and high-pressure gas to supersonic speed and convert it into thrust.
2. Structural stability guarantee: Graphite nozzles can also maintain dimensional stability in the metal-rich particle scouring environment of aluminum-containing solid fuel and ensure that the thrust curve meets the design.
