Abstract:
A propulsion system combined with a bipropellant rocket using hydrogen peroxide gas generator and an operating method of the same are provided to progress as a ramjet gradually by initially forming combustion chamber environment in the ram combustion for thrust generation. A propulsion system combined with a bipropellant rocket using hydrogen peroxide gas generator comprises: a diffuser(160); a fuel injection nozzle(150); a combustion chamber; a control door(400) being equipped at the inlet of the diffuser and controlling air volume; a hydrogen peroxide gas generator(300) equipped at the front end of the combustion chamber; and a controller controlling the control door, a gas generator and a fuel injection nozzle. When the controller controls the control door and the hydrogen peroxide gas generator, inhaled air volume is gradually increased and the power of the hydrogen peroxide gas generator is gradually decreased.
Abstract:
A supersonic ejector having a minimum pressure load and a driving method thereof are provided to operate the supersonic ejector with a minimum pressure of the ejector through a simple operation. A supersonic ejector having a minimum pressure load comprises a first compressor(50), a first dryer(52), and a main tank(54). The first compressor is serially connected to the first dryer and the main tank. A second compressor(60) is serially connected to a second dryer(62) and a service air tank(64) to remove moisture in the air. The main air tank and the service air tank are connected to a set chamber. The set chamber(70) is configured and a user can set a target pressure. The pressurized air discharged from the set chamber is injected into a drive fluid part of the supersonic ejector through a first valve(72). The injection amount can be adjusted by an opening level of the first valve.
