Embodiment Construction
[0041] The present invention will be further described below in conjunction with the accompanying drawings.
[0042] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides an electronically controlled harpoon grill helicopter landing aid system to solve the problem that the existing harpoon grill system has a complicated mechanical structure, heavy structural weight and complicated system. It needs regular maintenance and inconvenient use.
[0043] see image 3 , and the electronically controlled harpoon grill helicopter landing aid system of the present embodiment, the main components are as follows:
[0044] Harpoon, Grille and Harpoon Controller.
[0045] The grid 1 is a standard part, that is, the grid of this system also adopts the same domestic standard grid as the "Zhi 9" helicopter, such as figure 1 and image 3 As shown, the grille is fixed on the ship.
[0046] see Figure 4 and Figure 5 , and the harpoon and ha...

The invention discloses an electric control fishgig-grating deck landing assisting system for a helicopter. The electric control fishgig-grating deck landing assisting system is mainly composed of a fishgig, a grating and a fishgig controller. When the shipboard helicopter is in a severe sea condition, problems, caused by ascending or descending or swinging of a warship, existing in the deck landing and tying on the warship are mainly solved. Full electric drive and control are adopted, and the electric control fishgig-grating deck landing assisting system has the advantages that because an independent hydraulic or pneumatic power source is not needed, the mechanical structure is simple, operation is stable, responding is rapid, acceleration is high, the frequency band is wide, the service life is long, adjusting parameters can be programmed, and the electric control fishgig-grating deck landing assisting system and a flight control system are conveniently integrated.
Description
technical field [0001] The invention relates to the field of aviation technology, in particular to a helicopter landing aid system. Background technique [0002] Helicopter landing is a more complicated process than landing, and the special issues that need to be considered are as follows: [0003] (1) The influence of the turbulent surface flow field on the helicopter maneuvering. The influence of the buildings on the deck and the gust of wind at sea makes the airflow state on the deck very complicated, and there are small torrents, etc. Once encountering an unexpected flow field state, it is likely to cause abnormal aerodynamic response of the helicopter and cause damage to the aircraft ; [0004] (2) The deviation of landing point is allowed. Since the landing deck is always moving under the action of sea waves and sea wind, the safe landing range is also constantly changing. The deviation of the landing point increases with the increase of wind waves and ship speed. ...
