Downwind direction controller

Abstract

A downwind controller is composed of a wind indicator, a potentiometer, a controller and a support. The wind indicator is hung on a potentiometer rotating shaft; a potentiometer seat is arranged in a pin control of the rectangular frame through the rotating shaft; the wind direction controller is installed at the top of the front end of the airship, the wind indicator rotates along with wind and can drive the potentiometer to rotate synchronously, the potentiometer is an adjusting end of the controller, the controller can output forward and reverse rotation control signals by rotating the potentiometer, and the forward and reverse rotation control signals can control airship direction wings to rotate synchronously along with the wind direction so as to achieve downwind control of the airship. The controller not only can be used for controlling a power airship, but also can be used for a tethered boat, can control the airship to hover in the downwind direction through flight control, and can also greatly improve the downwind performance of the tethered boat when being used for controlling the tethered boat.

Description

Technical Field

[0001] The invention belongs to the field of aerostats, more specifically to airship or moored boat components. Background Art

[0002] At present, the wind resistance of small and medium-sized airships generally does not exceed level four or five. The main reason is that the crosswind wind resistance is very large, and it is difficult to cope with strong winds. Since the airship is in the shape of a teardrop, there is the smallest wind resistance in the downwind direction. If the airship can maintain the downwind state, it can resist greater winds. At present, if the airship needs to stay in the air at a certain point, the control difficulty is relatively high. If it is remotely controlled, the rudder needs to be constantly controlled to align with the wind direction, and the appropriate throttle needs to be adjusted to balance the wind and power to achieve hovering. However, there is currently no airship flight control system that can control hovering. The main reason is that it is impossible to judge the wind direction. At present, the fixed point control with the flight control is generally achieved by circling, but if there is a strong wind during circling, the crosswind may cause the airship to fly far away, and it takes a lot of power to return to the vicinity of the fixed point. This especially restricts the application and development of stratospheric airships, because stratospheric airships generally need to hover in the air for a long time at a certain point. If a downwind controller is used, downwind control can be easily achieved, and long-term hovering controlled by the flight control can also be achieved. Summary of the invention

[0003] The present invention provides a downwind direction controller which can be switched to a downwind direction control state by remote control or the like to achieve hovering and cope with the influence of strong wind on an airship. In particular, it can be switched to flight control for long-term fixed-point hovering, and directional movable wings can be added to a tethered boat to improve the downwind direction performance of the tethered boat.

[0004] The present invention is realized in the following manner: a downwind direction controller, which consists of a wind vane, a potentiometer, a controller and a bracket; the wind vane is hoisted on a potentiometer rotating shaft, a potentiometer seat is installed in a pin control of a rectangular frame through a pin shaft, an extension shaft of the potentiometer rotating shaft passes through a wind vane rod and extends to the lower end of the rectangular frame and is fixed with a gravity hammer, and the lower end of the rectangular frame is fixed on the front upper side capsule of an airship through a supporting rod and a flange plate; the wind vane can be kept in a horizontal state by rotating around the pin shaft on the potentiometer seat through the gravity hammer; the wind vane can drive the potentiometer to rotate with the wind direction to output a control signal for the synchronous rotation of the airship directional wing to the controller, so as to realize the downwind direction control of the airship.

[0008] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention. The present invention is implemented in the following way: a downwind direction controller, consisting of a wind vane 1, a potentiometer 2, a controller 7, and a bracket; wherein the bracket is composed of a support rod 5 and a flange 6; the potentiometer 2 shaft suspends the wind vane 1, and the potentiometer seat is installed in the pin hole of the rectangular frame through a pin shaft. The extension shaft of the potentiometer shaft passes through the wind vane rod and extends to the lower end of the rectangular frame and is fixed to the gravity hammer 4, and its extension shaft is connected to the potentiometer shaft through a coupling sleeve; the lower end of the rectangular frame is fixed to the upper side of the front end of the airship hull 8 through a support rod 5 and a flange 6.

[0009] The wind vane of the present embodiment can be kept in a horizontal state by rotating around the pin shaft on the potentiometer seat through the gravity hammer; the wind vane can have better wind-following performance and more flexible rotation by keeping in a horizontal state.

[0010] The wind vane rotates with the wind direction, which can drive the potentiometer to rotate and output a control signal to the controller for the synchronous rotation of the airship's directional wing, so as to realize the downwind control of the airship; the output signal of the controller controls the steering of the directional wing through the connection and the switching switch, and the switching switch can be switched to downwind controller control or remote control, flight control, manual control state through remote control, flight control, manual control and other control methods. When switched to remote control, flight control, manual control state, the airship is in a conventional control state, and the downwind controller no longer interferes with the flight direction.
