Abstract
The utility model relates to a kind of motion sailing boat sail wing non-standard ellipsoid whirlpool maker, be made up of half non-standard ellipsoid, strip bottom support bracket, pressure sensitive adhesive, viscosity inside story, it is characterized in that: strip bottom support bracket is divided into quarter, the two ends of half non-standard ellipsoid are fixed on the equal portions place at strip bottom support bracket one side two ends by pressure sensitive adhesive, viscosity inside story is fixed on the equal portions place at strip bottom support bracket another side two ends by pressure sensitive adhesive; Centre two equal portions of strip bottom support bracket are folding to be bonded together by pressure sensitive adhesive, and makes two equal portions at strip bottom support bracket two ends connect into straight line.Remove the viscosity inside story of strip bottom support bracket during use, strip bottom support bracket is adhered on sail aerofoil just passable.The utility model economy, easily installation are also easily dismantled, and can improve the flowing of sail wing surrounding air.
Description
Technical field
The utility model relates to the motion sailing boat sail wing non-standard ellipsoid whirlpool maker, belongs to field of fluid mechanics.
Background technology
The wind produced when ship wind is sailing, wind speed just equals sail navigation speed, and direction is contrary with sailing boat working direction.If the size of true wind speed represents with V1, relative wind velocity V is exactly the Vector modulation of ship wind V2 and true wind speed V1, and relative wind velocity V is course angle with the angle in navigation direction, and apparent wind is the actual wind that the sailing boat sail wing bears.Angle between apparent wind and sail wing sail string is the angle of attack.
After the sailing boat sail wing is subject to apparent wind effect, define lift and resistance on the sail wing, this lift and resistance are due to sail wing ambient air flowing formation.When air flows through sail wing surface, create low pressure at the lee face of the sail wing, create high pressure in the windward side of sail, just this results in the aerodynamic force suffered by the sail wing by sail wing windward side and lee face like this, lift and resistance can be broken down into.Lift, resistance are respectively perpendicular to apparent wind direction with along apparent wind flow direction.Also sail wing combined air force is resolved into thrust and side force when sailing is studied.
As mentioned above, the aerodynamic force of the sail wing is the pressure difference formation of sail wing windward side and lee face.The Pressure difference distribution of sail wing surface is different at sail wing diverse location.When air flows through sail wing lee face, starting is laminar flow, becomes turbulent flow subsequently, and there is flow separation in stall spot.Transition position along with the shape of the sail wing different with the angle of apparent wind and different, be commonly referred to be at distance chord length place, sail wing bench section, sail wing forerunner limit 1/10 to 2/10.If generation flow separation, so the propulsion coefficient of the sail wing will reduce.If the separation point of the sail wing can postpone or can move along the sail wing backward, so the lift of the sail wing just can increase.
Summary of the invention
For above-mentioned Problems existing, the purpose of this utility model is to provide a kind of newly, the economic motion sailing boat sail wing non-standard ellipsoid whirlpool maker, improves the flowing of sail wing surrounding air.
To achieve these goals, technical solution of the present utility model is:
The motion sailing boat sail wing non-standard ellipsoid whirlpool maker, be made up of half non-standard ellipsoid, strip bottom support bracket, pressure sensitive adhesive, viscosity inside story, it is characterized in that: strip bottom support bracket is divided into quarter, the two ends of half non-standard ellipsoid are fixed on the equal portions place at strip bottom support bracket one side two ends by pressure sensitive adhesive, viscosity inside story is fixed on the equal portions place at strip bottom support bracket another side two ends by pressure sensitive adhesive; Centre two equal portions of strip bottom support bracket are folding to be bonded together by pressure sensitive adhesive, and makes two equal portions at strip bottom support bracket two ends connect into straight line.
Described strip bottom support bracket length is 2 ~ 6 centimetres, wide 1 ~ 2 centimetre.
Described pressure sensitive adhesive is that poly-ester fibres is made, and very soft can being easy to like this of poly-ester fibres is folded into whirlpool of the present utility model maker.
Described half non-standard ellipsoid is flexible body, size: wide 1 ~ 2 centimetre, long 2 ~ 12 centimetres, can be pasted onto completely on strip bottom support bracket, and fold along with strip bottom support bracket.
Remove the viscosity inside story of strip bottom support bracket during use, strip bottom support bracket is adhered on sail aerofoil just passable.
Adopt above technical scheme, the utility model has the following advantages, provide a new whirlpool maker to yachtsman, its is economical, easily install and also easily dismantle, so yachtsman can test the performance of the whirlpool maker of their concrete sail wings very easily very much.
Accompanying drawing illustrates:
Fig. 1 is strip bottom support bracket schematic diagram of the present utility model.
Fig. 2 is the lateral plan that non-standard ellipsoid of the present utility model is bonded on strip bottom support bracket.
Fig. 3 is schematic diagram of the present utility model.
Fig. 4 is the schematic diagram that the utility model is arranged on the sailing boat mainsail sail wing.
Detailed description of the invention
Be described in further detail the utility model below in conjunction with accompanying drawing, when description below relates to accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawing represents same or similar key element.Embodiment described in following exemplary embodiment does not represent all embodiments consistent with the disclosure.On the contrary, they only with as in appended claims describe in detail, the example of apparatus and method that aspects more of the present disclosure are consistent.
The utility model is made up of half non-standard ellipsoid 200, strip bottom support bracket 100, pressure sensitive adhesive 201, viscosity inside story 202; As shown in Figure 1, strip bottom support bracket 100 is divided into quarter by the fold line 101 of three parallel transverse directions, long 2 ~ 6 centimetres of described strip bottom support bracket 100, wide 1 ~ 2 centimetre; As shown in Figure 2, the two ends of half non-standard ellipsoid 200 are fixed on the equal portions place at strip bottom support bracket 100 one side two ends by pressure sensitive adhesive 201, viscosity inside story 202 is fixed on the equal portions place at strip bottom support bracket 100 another side two ends by pressure sensitive adhesive; Centre two equal portions of strip bottom support bracket 100 are folding to be bonded together by pressure sensitive adhesive 201, and makes two equal portions at strip bottom support bracket 100 two ends connect into straight line, is made into whirlpool maker as shown in Figure 3.Described pressure sensitive adhesive 201 is made for poly-ester fibres, and very soft can being easy to like this of poly-ester fibres is folded into whirlpool of the present utility model maker.Described half non-standard ellipsoid is flexible body, size: wide 1 ~ 2 centimetre, long 2 ~ 12 centimetres, can be pasted onto completely on strip bottom support bracket, and fold along with strip bottom support bracket.
As shown in Figure 4, during use, remove the viscosity inside story 202 of strip bottom support bracket 100, strip bottom support bracket 100 is adhered on sail aerofoil just passable.What by mode, adjacent whirlpool maker is installed to determine according to the flow field situation around the sail wing.Normal conditions in order to find the best position of whirlpool maker, carry out at an arbitrary position test and numerical modelling be necessary.In this exemplary embodiment, whirlpool maker is arranged on mainsail, but they also can be arranged on forerunner effectively.
