Title: Nikolai Fedorovich Molev: Innovator in Gas Generator and Combustion Chamber Technologies

Introduction

Nikolai Fedorovich Molev is a notable inventor based in Khimki, Russia. He has made significant contributions to the field of engineering, particularly in the development of gas generators and combustion chambers. With a total of 2 patents, his work showcases innovative methods that enhance the efficiency and functionality of rocket propulsion systems.

Latest Patents

Molev's latest patents include a method for producing a gas generator of welded-brazed construction. This gas generator is composed of separate units, including a mixing head, a casing, and an outlet branch pipe, which are interjoined by welding. The mixing head is welded to the outlet branch pipe through a spacer and a structural spherical casing. The spacer and the outlet branch pipe are made of two inter-brazed envelopes, with the inner envelopes welded at their end faces by electron-beam welding. The outer structural envelopes are welded by electron-arc welding using a split ring. The spherical casing of the gas generator is welded to the outlet branch pipe and the mixing head after the spacer is welded to both components.

Another significant patent is for a method of producing a welded-brazed combustion chamber. This combustion chamber is designed for a liquid-propellant rocket engine and includes an injector head joined to a combustion chamber casing with an exhaust head on the nozzle output. The casing consists of a steel jacket and a bronze-steel internal fire wall, which are joined together and contain shells connected in series. The exhaust head and shells of the casing are brazed using a solder based on nickel, chromium, and manganese. Parts of the injector head and other members of the combustion chamber casing are brazed using a copper-silver solder. The shells of the fire wall are connected by electron-beam welding, directing an electron beam into axial gaps left while brazing between the shells of the jacket.
