Detailed description of the invention

By further illustrating the technological means and effect that the utility model taked by reaching predetermined technique purpose, below in conjunction with accompanying drawing and preferred embodiment, structure of the present utility model, feature and effect are described in detail as follows.

As Fig. 3, Fig. 4, Fig. 5, Fig. 6 show an embodiment of the present utility model, the transfer for air ship in this embodiment, including manipulating bracing wire 19 and turning to rudder plate 9, the corresponding screw 11 of rudder plate 9 is turned to be arranged on protection cage 8 rear portion, turn to rudder plate 9 to include rudder plate body 9-1, rudder plate body 9-1 is provided with rotating shaft or axis hole, rotating shaft or axis hole and arranges along rudder plate body 9-1 length direction, rudder plate body 9-1 cross section in the width direction is that fairing is wing, the widest at rotating shaft or axis hole.The present embodiment uses axis hole 9-5.

Rudder plate is turned to overlook as long drops, two ends are narrower, at rotating shaft, width is maximum, this kind of design primary concern is that and reduce the windage that rudder plate is subject to along hull vertical line direction, increase the contact area of rudder plate side and air stream, making rudder plate play optimal rotating effect while little torque rotation, the manipulation rudder stock farthest reducing driver makes firmly, makes driving air ship more comfortable, light.

As it is shown on figure 3, the axial line distance screw 11 center 400-420mm of rotating shaft or axis hole, turn to rudder plate 9 transverse center linear distance power set shaft axis 90-100mm.

Specifically, the axial line distance propeller center 415mm of rotating shaft or axis hole, turn to rudder plate 9 transverse center linear distance power set shaft axis 95mm.

As shown in Figure 6, the long 1225mm of rudder plate body 9-1, wide 560mm.

Depending on the profile arrangement turning to rudder plate is based on the size of hull and the power size of air ship engine prop generation, 1225 × 560mm is suitably sized to hull size 4800 × 2400mm, and engine power is the air ship of 330hp.

Rudder plate body 9-1 hollow, lumen loading expanded material, both can guarantee that integral rigidity, intensity, can guarantee that again light.Rudder plate body 9-1 afterbody is provided with little tailgate 9-4；Rudder plate body 9-1 arranges two panels, arranges the linkage of connecting rod 9-6 in lower end, and connecting rod 9-6 is hinged with rudder plate body 9-1.

The steering locking angle degree turning to rudder plate 9 becomes 40-45 ° with hull vertical line, and the steering moment turning to rudder plate 9 is 120-130nm.

As shown in Figure 6, rudder plate body 9-1 is provided with axis hole 9-5, axis hole 9-5 and arranges along rudder plate body 9-1 length direction, protection cage rudder plate installing rack is provided with the rotating shaft of cooperation, needing therebetween, plastic sheath is set and plays bearing effect.

As it is shown in figure 5, manipulation bracing wire 19 includes that the connection of bracing wire body 19-2, bracing wire body 19-2 two ends has pull bar, being divided into front tension bar 19-1 and back stay 19-4, front tension bar 19-1 to connect manual manipulation bar, back stay 19-4 connection turns to rudder plate 9.

Back stay 19-4 is located in sliding sleeve 19-3, and sliding sleeve 19-3 is fixed on protection cage 8, turns to rudder plate 9 bottom to be provided with connecting shaft 9-3 and connects back stay 19-4.

Bracing wire body 19-2 uses stainless steel wire, and stainless steel wire is located in protection set.

In sum, the utility model has the advantage that

Through experimental verification, turn to the steering locking angle degree of rudder plate when it becomes 40-45 ° with hull vertical line, air ship turning efficiency is best, if steering angle is less than 40 °, needs the biggest radius of turn, be unfavorable for during fast running controlling its direction, if steering angle is more than 45 °, owing to its front face area is excessive, it is unfavorable for turning to rudder plate just to return, is easily caused the rollover of air ship.The steering moment of design rudder plate is 120-130mm, through experimental verification air ship handling best in the range of this, if steering moment is less than 120mm, according to lever principle, now manipulate rudder stock is used in laborious state, is unfavorable for turning to rudder plate just to return, if steering moment is more than 130mm, in the case of manipulation bracing wire stretching travel is constant, the anglec of rotation meeting relative reduction of rudder plate, experiment proves that this kind of situation is the most inadvisable.

Turning to rudder plate to be fixed on protection cage, its installation site is determined by the propeller position in dynamical system, draws through many experiments, and the cross-sectional distance of its rotating shaft and propeller hub, when 400-420mm, turns to rudder plate safety coefficient the highest, and turning efficiency is best；If both are smaller than 400mm, when adjusting propeller blade angle, the two hypotelorism, easily cause screw and turn to the damage of rudder plate, if it addition, the two hypotelorism, being unfavorable for the smooth and easy circulation of air stream, affecting the travel speed of air ship；If the distance of the two is more than 420mm, owing between the two away from excessive, the air-flow that propeller rotational produces will produce active force largely to rudder plate, causing air ship general safety coefficient and reduce, therefore turning efficiency also can reduce.

Rudder plate is also turned to the spacing turning to rudder plate cross central line and has a great impact by screw rotating shaft simultaneously, when between the two away from for 90-100mm and when turning to rudder plate cross central line in oar axle lower end, airflow acting force owing to now turning to rudder plate lower half to be subject to is bigger, air ship handling best, the derivative power being perpendicular to water surface direction produced is minimum, air ship mobility now is best, and stability is the highest；When turning to rudder plate cross central line in oar axle upper end, the installation site of rudder plate is too high, adds the whole height of air ship, and stability is substantially reduced, and the power being perpendicular to water surface direction of generation has had a strong impact on the gait of march of air ship；When both are smaller than 90mm and turn to rudder plate cross central line in oar axle lower end, both are close together, cause rudder plate bearing up-down force size close, owing to screw rotating shaft is with the horizontal certain angle, so now rudder plate bearing up-down force is close is unfavorable for that hull travels in the horizontal direction, therefore the travel speed of air ship can reduce；When between the two away from more than 100mm and when turning to rudder plate cross central line in oar axle lower end, turn to rudder plate to rotate produce vertical the most excessive with the power in water surface direction, also can have a strong impact on the gait of march of air ship.

Described above simply to illustrate that the utility model, it is understood that the utility model is not limited to above example, meets the various variants of the utility model thought all within protection domain of the present utility model.
