Research demonstrates enhanced thermal stability and electrochemical properties in composite materials for electric rocket engines, indicating potential for improved performance.
This work is devoted to creation of vacuum-tight composite material based on organic binder for manufacture of dielectric parts for electric rocket engines of large diameter considering requirements to their electromagnetic permeability thermal stability and vibration resistance. Results of the study has showed the most effective way to increase the vibrational resistance of thin-walled ceramic parts is to assemble them on an elastic heat-resistant adhesive from ceramic sectors of simplified shape. The experiment was conducted using two functional prototypes of discharge chambers of electric rocket engine. It has been disclosed that Prototype A has a higher density of material compared to Prototype B. Moreover the electrochemical properties and the highest temperature limit of Prototype A are better than that of Prototype B.
