Description

Suspended wing mobile take-off and landing device and method

Technical field

The present invention relates to a maneuvering take-off and landing device and a method of taking off and landing of an aircraft such as a wing, a paraglider, and an ordinary parachute.

Background technique

At present, the flight of hang-wings and unpowered paragliders that take off in mountain conditions needs to meet one of the basic conditions: that they have suitable terrain. Pilots need to carry a flying wing or paraglider to climb the mountain first, then assemble the flying wing, and then take off with the upwind of the mountain upwind slope. Therefore, the sport currently has the disadvantages of being restricted by terrain, being unable to be carried out in the vast plains and coastal areas, and taking off and taking time.

Summary of the Invention

The object of the present invention is to provide an aircraft, such as a wing and a paraglider or an ordinary parachute, which can be taken off frequently on land or on the water and can take off frequently and conveniently. Mobile flying device and flying method.

The purpose of the present invention is achieved as follows: When taking off on the water surface, a winch and a corresponding operating system are provided on the speedboat. The system is equipped with a retracting and releasing device and a braking device to control the working state of the winch. A certain length of high-strength rope is coiled on the winch. The other end of the rope is connected to a suspension aileron through a set of aircraft take-off and attitude control ropes, and the suspension aileron is connected to the suspension wing through a set of locking and tripping devices. At this time, the position between the suspension wing and the cantilever aileron is parallel, similar to the biplane structure of a fixed-wing aircraft, with the suspension wing up and the suspension aileron down. The function of the suspension wing is to carry people. The function of the suspension aileron is to provide a certain lift during the take-off phase, thereby shortening the take-off distance. The first is to lift the traction rope after the suspension wing is decoupled from the air. Provides a lift to prevent it from falling into the water, which facilitates the retraction of the traction rope. A take-off and landing platform is provided above the speedboat. The platform is provided with suspension wing support and fixing devices. The suspension wings are fixed on the landing platform by the fixing device. At this time, the suspension wings are high in front and low in height, and have an upwind angle. The platform is also provided with a traction rope positioning vehicle or a traction point positioning wheel to control the front-to-back change of the traction point. The front-point traction can ensure that the hanging wing leaves the boat smoothly when taking off on the speedboat. The hanging wing leaves the boat and becomes the rear point. Towing to ensure the stability of the towing speed boat at high speeds. Start the speedboat and gradually accelerate it. When the speed of the boat reaches the take-off speed of the wing, open the lock of the fixed wing on the boat, control the winch rope and brake, and move the towing point from the front of the speedboat to the speedboat. In the rear part, the process of rope release and traction is repeatedly performed, so that the suspension wings are gradually raised. This work step is basically the same as that of our kite flying. At this time, the flying attitude of the suspension wing is basically controlled by the attitude control rope of the suspension aileron. After the flying wing is released to a predetermined height, the pilot controls the trip device in the air to disengage from the flying aileron and enters the main flight phase.

After disengaging from the suspension wing, the hovering aileron continues to provide a lift for the flying rope so that it does not fall into the water. At this time, the winch is manipulated to retract the flying rope for the next take-off.

Another way to take off the wing is by land. The method is as follows: a certain length of traction rope is pre-released. When the speedboat starts, because the traction force at this time is not enough to take off the cantilever wing, the pilot needs to take a few steps forward. At this time, the hanging wing takes off and enters the traction raising stage.

The above-mentioned suspension flight may not be provided with a suspension aileron, and the traction rope may be directly taken off by the traction rope through the takeoff and landing attitude control rope.

The take-off and landing attitude of the suspension wing can be controlled by the take-off and landing attitude control rope, or by the pilot.

The flying winch can be operated either mechanically or manually.

The flying takeoff and landing device and takeoff and landing method mentioned above can also be used to fly or tow a flying glider or parachute. When flying a paraglider or parachute, Instead, the aileron is suspended by using a smaller auxiliary parachute to provide gravity for the towline. The parachute is closed in parallel. When the pilot is ready to leave the towline for autonomous flight, the parachute is opened.

There are four ways to hang the wing: First, it freely lands on the speedboat. This way of landing requires the driver of the speedboat to control the relative position and speed of the speedboat and the suspension wings, so that the relative speed of the two is zero as much as possible. The pilot needs to control the descent speed and angle. The disadvantage of this method is that the stability is poor when the crosswind or wind is strong; a landing method is that after the suspension wing has landed to a certain height, the pilot lowers a certain length. The landing rope is connected by the personnel on the speedboat to the traction rope on the winch, so as to restore the traction flight status of the speedboat to the hanging wing. At this time, the rope retraction device of the winch is activated to retract the hanging wing to the take-off and landing of the boat Platform; the other two landing methods are the same as the current suspension wing landing method, one is free landing on land; the other is free landing on water.

Because the above-mentioned flight and landing methods are adopted, the take-off of such a wing or paraglider no longer depends on the mountain highlands, and it can take off conveniently on the vast sea, lake or river, thus making this flight Compared with the current wing or paraglider flying on mountain terrain conditions, it becomes both labor-saving and efficient, and greatly expands the activity space of this sport, which is highly entertaining.

A winch system 3 is provided on the speedboat 1, and the system is equipped with a rope retracting device, a rope releasing device, a rope arranging device and a braking device to control the working state of the winch. There are two ways of the winch's power system: one is to directly use the engine as the working power, and to control the various working states of the winch through a set of variable speed, steering gear and corresponding transmission, clutch, and brake devices; another way Is: a generator is set on the engine power output shaft, the generator is connected to the engine through a gear or a pulley, a clutch, and a set of rectifiers, relays, control buttons is connected to the battery and the motor under the generator, so that the generator sends Electricity can either directly drive the motor through rectification, then drive the winch through the motor, or charge the battery, and then use the power of the battery to drive the winch to drive the motor. The battery can also provide power to other electrical appliances on board. A certain length of high-strength traction rope 4 is coiled on the winch, and the other end of the rope is connected to the suspension aileron 7 through a set of suspension wing take-off and landing attitude control ropes. The attitude control ropes are divided into three-wire and four-wire The suspension aileron is then connected to the suspension wing 8 through a set of locking and tripping devices. At this time, the position between the suspension wing and the suspension aileron is parallel, similar to the bi-wing structure of a fixed-wing aircraft, with the suspension wing up and the suspension aileron down. The function of the suspension wing is to carry people. The function of the suspension aileron is to provide a certain lift during the take-off phase, thereby shortening the take-off distance. Into the water surface to facilitate the retraction of the traction rope. The paraglider for flying paragliders or ordinary parachutes also has the same function. This traction device is used to fly a paraglider or a normal parachute. When the pilot is ready to leave the traction flight state and enter autonomous flight, Open before row status. A take-off and landing platform 10 is provided above the speedboat, and the platform is provided with a traction rope positioning vehicle system 5, or front traction wheels 5 and rear traction wheels 9, and suspension wing support and fixing devices 11, the suspension wings are fixed to the hoisting device by the fixing device. On the landing platform, the suspension wings now have a high front and a low back, with an upwind angle. Start the speedboat and gradually accelerate it. When the speed of the boat reaches the take-off speed of the wing, open the lock device of the fixed wing on the boat, control the winch release and brake device, and repeatedly engage in the work procedure of release and traction. This makes the suspension wing rise gradually. This work step is basically the same as when we fly a kite. At this time, the flying attitude of the suspension wing is basically controlled by the take-off and landing attitude control rope 6 of the suspension aileron. After the flying wing is released to a predetermined height, the pilot controls the trip device in the air to disengage from the flying aileron and enters the autonomous flight phase.
