Model rocket engine

Abstract

The invention relates to a model rocket, in particular to a model rocket engine. The model rocket engine comprises a shell body, an electronic ignition head (1), a catalyst sprayer, catalyst particles (2), a cap (3), a storage tank bottom cover (6), a propellant inlet (8), a diaphragm (7), a working medium and a catalyst net thrust chamber (9), wherein the shell body is composed of a storage tank top cover (4), a storage tank shell body (5) and a spray pipe (10); the catalyst sprayer and the catalyst particles (2) surround the periphery of the electronic ignition head (1); the cap (3) is used for packaging the catalyst particles (2) from the lower portion in a normal state; the storage tank bottom cover (6) is arranged on the lower middle portion of the interior of the shell body and used for sealing the storage tank shell body (5); the propellant inlet (8) is located in the center of the storage tank bottom cover (6); the diaphragm (7) covers the propellant inlet (8); the working medium is packaged inside the storage tank shell body (5); and the catalyst net thrust chamber (9) is located between the storage tank bottom cover (6) and the spray pipe (10). According to the model rocket engine, the safety is good, the working temperature is low, no high-temperature flame is ejected out, and exhausted gas is clean and environmentally friendly; and the model rocket engine can serve as a power system to be widely applied to science popularization, education and entertainment.

Description

technical field [0001] The invention relates to a model rocket, in particular to a model rocket engine. Background technique [0002] At present, most commercial model rocket engines use black powder as the main propellant. Black powder has high impact sensitivity, friction sensitivity and electrostatic sensitivity, and is dangerous during transportation and storage. The high-temperature flames emitted can easily ignite surrounding objects and cause accidents. The discharged gas contains harmful substances such as sulfur dioxide and nitrogen oxides, which is poor in safety and environmental protection. Contents of the invention [0003] The purpose of the present invention is to provide a model rocket engine that can overcome the deficiencies of the prior art and is safer and more environmentally friendly. [0004] The technical solution of the present invention is: a model rocket engine, which includes: a casing composed of a storage tank top cover, a storage tank shell ...
