Internal combustion type self-starting ramjet engine

Abstract

The invention discloses an internal combustion type self-starting ramjet engine. The shapes of a front stage and a rear stage of the internal combustion type self-starting ramjet engine are the same,the front stage and the rear stage are composed of spherical front tubes and vertebral tail tubes. The vertebral tail tubes of the front stage enter into the spherical front tubes of the rear stage, the front stage is a main body of the internal combustion type self-starting ramjet engine, the rear stage is a passive thrust lifter, and is equivalent to a large ducted fan. A methanol gasifier is installed in an engine shell body of the front stage, and a combustion chamber of the methanol gasifier is internally wound around a coiler in a wall-attached mode. One end of a pipeline A is connectedwith a high-pressure alcohol pump, the other end of the pipeline A is connected with one end of the coiler, and the other end of the coiler is connected with a pipeline D. The tail end outlet of the pipeline D is a methanol high-pressure nozzle B, and a valve V is installed at the initial end of the pipeline D. A windproof torch group is arranged adjacent to the methanol high-pressure nozzle, thewindproof torch group is composed of six torches, and the flame orientations of the torches are the front, the rear, the top, the bottom, the left and the right. The internal combustion type self-starting ramjet engine has simple structure, no gas turbine, no compressor and no fan, and the process is extremely simple.

Description

technical field [0001] The present invention relates to the field of engine technology, more specifically, to an internal combustion type self-starting ramjet engine (Neiranxing. Ziqidong. Chongya. Fadongji, abbreviated as NZCF). Background technique [0002] Aircraft power mostly uses turbofans, and multiple factors restrict the improvement of turbofans, such as: vibration limits the increase of the fan (bypass ratio), sound speed limits the lengthening of compressor blades, and heat-resistant materials limit the increase in temperature before the vortex, etc. . There are also fatal flaws in turbofans, such as: surge, flying birds...; turbofans are especially not suitable for hypersonic flight. [0003] In the early days, someone installed a small ramjet on the tip of the rotor, turned the rotor manually, started the ramjet, and then went straight up. Among the surface-to-air missiles in active service, the second stage mostly uses punching machines. The stamping machine...

But so far the stamping machine has not been used in the aircraft: just because the stamping machine cannot start at zero speed
