Environment

The combustion chamber in a rocket engine is a main critical part since this area creates the thrust needed to propel the rocket or spacecraft. In order to function properly, this chamber needs to endure extreme temperatures and pressures as well as intense vibrations.

Challenge

The biggest challenge encountered in a rocket’s combustion chamber is managing the constant variation of temperature and pressure. Along with this critical-mission technical element, you must also factor in the required low load and stringent tightness level.

Solution

High-performance sealing solutions such as Omniseal® metal C-Seals create a tight seal between the combustion chamber walls and the injector plate that is responsible for releasing propellants into the chamber. 

Why is a seal so critical in this area? A seal’s primary function is to prevent the escape of propellants and maintain a hermetic barrier. By selecting the optimal metal seal, it will provide the necessary resilience,  conforming to irregularities in mating surfaces and ensuring a tight seal.

Our metal C-Seals are engineered from advanced materials such as Inconel ®.  Valued for their resiliency, these solutions are critical for sealing control due to being able to cope with temperature and pressure variations.
