Abstract

An auxiliary power-assisted empennage for a water rocket, comprising a socket body, a fixed piece, a fastening bolt, an empennage, a deflector and a booster piece, the empennage includes a socket pipe installed between the tail of the water rocket body and the nozzle body; the outer wall of the socket pipe is provided with four tail fins extending radially; the socket body and the tail fins are fixedly connected by a fixed piece; the fixed piece is adhered to the outer wall of the socket pipe; the tail fin There are deflectors adhered between the fins; the upper surface of the connection between the deflector and the tail fin is provided with a booster sheet; the outer wall of the socket pipe is provided with 4 fastening bolts; the deflector is arc-shaped plate structure; the inner wall of the socket pipe is provided with threads; the booster plate is a tetrahedron structure with an inclined surface, and is attached to the tail fin and is seamlessly connected with the surface of the socket pipe body; the socket pipe body of the present invention is arranged. It is beneficial to install the empennage device on the water rocket more quickly and conveniently.

Description

technical field [0001] The invention relates to the technical field of supporting structures for water rockets and concrete empennages for play, in particular to an auxiliary booster empennage for water rockets. Background technique [0002] The water rocket is a toy designed using mass ratio and air pressure. It is also one of the famous cases in physics teaching. It can cultivate students' interest in physics learning, and the physical principles contained in it are an important basis for understanding mechanics in physics. . The empennage of the existing water rocket is usually installed and fixed on the middle and lower parts of the water rocket body, and its fixing method is mainly bonding. [0003] The inventors have found that most of the existing auxiliary power-assisted empennage devices for water rockets are not firmly fixed, and the air resistance of the empennage is relatively large, which is inconvenient for directional flight and complicated to install.
