2results about How to "Stable flight attitude" patented technology

The utility model discloses an unmanned plane soil remote sensing monitoring devices, include: support part, support part includes unmanned plane frame and machine base, machine base is fixed at the bottom of unmanned plane frame, spoiler part, spoiler part includes transverse board, spoiler, inner recess, rotating shaft and drive rod, transverse board is installed at the both sides of machine base outer surface, and inner recess is set up at the one end of transverse board top, and rotating shaft sets up at the both sides of inner recess inner surface, and spoiler rotatoryly connected between two rotating shafts, and drive rod sets up at the outside of one end rotating shaft. The utility model above -mentioned device when practical use, if external is in gale environment, airflow disorder makes unmanned plane flight attitude difficult steady control, and the lateral force and the jounce force that it receives increase greatly, this not only makes flight trajectory deviate predetermined route, also has improved the crash risk significantly, has reduced the stability when unmanned plane flight.

This utility model discloses a 38mm stun-type riot control bullet for riot guns, relating to the field of riot control ammunition technology. The utility model includes a launch tube assembly, the inner cavity of which houses a projectile assembly. The projectile assembly includes a projectile shell disposed inside the launch tube assembly. An end cap is fixedly connected to the bottom of the projectile shell, and a tail fin is fixedly connected to the bottom of the end cap. A flame delay detonator is fixedly connected to the bottom of the inner cavity of the end cap. This utility model reduces air resistance during flight by designing the projectile shell head as a spherical structure with a curvature radius of 15-20mm. Simultaneously, tail fins evenly distributed circumferentially at the bottom of the end cap form an aerodynamic layout similar to a stabilizing wing. The spherical head reduces wind resistance interference, and the tail fins balance attitude shift by generating aerodynamic lift. The combined effect of these two elements makes the projectile's flight attitude more stable, solving the accuracy problem caused by structural design defects in existing products.
