Embodiment Construction

[0027] The invention patent is a boron-based solid fuel ignition technology applied to propellers. By using a high-power plasma generator as an ignition device, the boron-based solid fuel placed in the thruster is heated, and its start-stop and power regulation are controlled through the power supply and electrical adjustment equipment connected to the plasma generator.

[0028] The ignition system consists of a plasma generator, an electrical control adjustment system, a water cooling system and a combustion injection system.

[0029] The plasma generator adopts high-frequency arc ignition under the condition of medium pressure greater than 0.12MPa by using direct current, and obtains directional flow air plasma with stable power under the control of strong magnetic field, and its temperature can reach above 5000K.

[0030] The electrical control adjustment system is composed of PLC, potentiometer, relay, contactor, etc., through the control circuit to adjust the switch of th...

Abstract

The invention relates to the technology of a propeller, which aims to provide a boron-based solid fuel propeller igniting through a plasma generator. The boron-based solid fuel propeller igniting by using the plasma generator comprises an air inlet, a gas generator, a secondary combustion chamber and a tail sprayer nozzle. The gas generator is internally provided with the boron-based solid fuel, the plasma generator is arranged at the tail end of the gas generator, and the plasma injection opening is aligned with solid fuel. The propeller further comprises an electric control and adjustment system for adjusting the power of the plasma generator and a cooling water system for cooling. The plasma generation process is stable, and high density heat can be provided within a certain time. Compared with conventional igniting powder applied to ignition of the boron-based solid fuel propeller, the ignition is not limited by operation time. Compared with the conventional igniting powder, the temperature is greatly enhanced, and ignition of the boron-based solid fuel can be realized. The ignition power of the plasma can be precisely adjusted through the power adjusting system, so that the invention provides the boron-based solid fuel propeller suitable for different dosages.

Description

technical field [0001] The invention relates to propulsion technology, in particular to solid rocket propulsion. Background technique [0002] At present, the solid fuel in the solid rocket ramjet (solid fuel propeller) is mainly ignited by ignition powder. Ignition powder is mainly composed of oxidizing agent, combustible agent and binder. It has stable physical and chemical properties, is sensitive to thermal shock, and has sufficient ignition ability. Fill the igniter into the igniter, ignite it with an electric spark, and release a large amount of heat to heat the solid propellant, thereby making it ignite and burn. Adopting this method needs to open up a part of space specially in the gas generator for placing the ignition powder, thereby reducing the filling amount of the propellant. And the method of using the ignition powder to ignite makes the propellant have a larger ignition delay, which reduces the sensitivity of the reaction. [0003] Because boron has excell...
