Description

TECHNICAL FIELD

[0001] The present application relates to the field of helicopter navigation aid, in particular to a portable navigation aid for helicopter field training. BACKGROUND

[0002] Most of the existing mobile navigation aid for helicopter adopts mobile vehicle type. Due to being too heavy, the car cannot reach the field area without road, and needs to be connected to the power supply of the vehicle. It is not suitable for use in harsh outdoor environment, and cannot be stably fixed on the ground in the field. It may cause tilting and rollover phenomenon. The sealing of the endurance lamp assembly has relatively high requirements, and cannot be backed up in the field. When the light power is consumed, it cannot be used again. The standby battery cannot be replaced in time. When the temperature is too low, the screw connection will be frozen and cannot be unscrewed. The endurance is relatively weak, which seriously affects the field training and flight safety. Therefore, a portable navigation aid for helicopter field training is designed.

[0018] Beneficial effects

[0019] Compared with the prior art, this application provides a portable navigation light for helicopter field training, which has the following advantages:

[0020] The bottom fixing device provided in this application can be a tail cone, a flange plate, or no other accessories. The tail cone, which is fixed to the ground, can be quickly screwed on and inserted directly into a softer surface. The flange plate can be placed on a harder surface and is equipped with a handle. Both the tail cone and flange plate fixing methods can prevent the navigation light from being blown over by airflow. At the same time, when no other accessories are provided, it can be used directly by hand. No additional wiring is required. The navigation light on the top, the battery box, the bottom button switch and the outer casing are electrically connected to form a closed power circuit.

[0021] The right-angle head and right-angle tail cone of this application are designed so that when the wind is too strong in the field, the vertically placed navigation light is prone to tilting and tipping over. Horizontal placement can stably fix it in the windy environment. The right-angle adapter at the tail cone can fix the navigation light a second time.

[0022] The battery box provided in this application has the same diameter at the bottom of the battery box shell as the bottom of the extended battery box shell, and the same diameter at the top of the extended battery box shell as the top of the rear cover; it is easy to disassemble and the number of batteries can be quickly increased or decreased, so that it can be modified to a single battery or dual batteries (multiple batteries) to improve the battery life of the navigation light.

[0023] The heating rings at the top and bottom of the extended battery box shell provided in this application are made of aluminum or iron. At the same time, the top O-ring, upper O-ring, bottom O-ring and middle O-ring all have the function of waterproof sealing. The bottom O-ring and middle O-ring also play the role of preventing short circuit. Compared with other metal materials, aluminum and iron have poor conductivity, higher resistance and more heat generation, which prevents the problem of being unable to replace the battery due to the interface being too cold.
