Abstract

The invention discloses a novel helicopter electric harpoon grille landing assisting system. The novel helicopter electric harpoon grille landing assisting system comprises a harpoon and a grille. The harpoon comprises an installation plate. The lower portion of the installation plate is provided with a gear box connected with a brushless direct current motor. The output end of the gear box is connected with one end of an inner barrel through matching of a ball screw and a screw nut, and the other end of the inner barrel is connected with a locking releasing mechanism matched with the grille. An electromagnet assembly used for controlling the locking releasing function of the locking releasing mechanism is arranged between the other end of the inner barrel and the locking releasing mechanism. The electromagnet assembly and the brushless direct current motor are controlled by a controller. The novel helicopter electric harpoon grille landing assisting system has the advantages of being simple in structure, light in weight, convenient to maintain, high in speed, free of pollution, low in power consumption and the like and solves the various problems caused by hydraulic drive.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to a novel helicopter electric harpoon grille landing aid system. Background technique [0002] The helicopter landing process is a complex process, which is easily affected by external natural conditions, and has the following problems: [0003] (1) The influence of external natural conditions on the helicopter: the influence of the turbulent airflow and sea breeze generated after the helicopter approaches the ship surface, resulting in the instability of the helicopter's state in the air when it lands; [0004] (2) The influence of external natural conditions on the ship: the ship keeps moving under the action of waves and sea wind, etc., resulting in the relative movement of the landing area relative to the helicopter; [0005] (3) The relative displacement between the helicopter and the ship surface after landing: when there is no mooring facility or the mooring is not firm, ...
