Description
Technical field
Utility model is related to a kind of parafoil, and in particular to a kind of double-vane umbrella.
Background technique
The same wing of parafoil shape, the reason of generating air force, are identical as general straight wing, according to bernoulli principle,
The air velocity of top airfoil is fast, forms low pressure, and lower aerofoil air velocity is slow, forms high pressure, and upper and lower aerofoil forms pressure difference, generates
Air force and torque.Parafoil mainly has keel type parafoil and parafoil, and keel type weight is larger and structure is relative complex,
Therefore application is seldom.The parafoil overwhelming majority applied at present is ram air parachute, and this parafoil is the flexible part made of fabric
Part.It is made of upper and lower aerofoil and rib, and rib extends parafoil to many gas chambers are divided into, and has venthole on fin.Parafoil
Leading edge extend to be opening (parafoil having has several closed air chambers at both ends).Ram-air enters gas chamber by opening,
The indoor pressure of gas is set to be greater than the pressure outside gas chamber, canopy is just filled, and parafoil section is made to reach designed air foil shape.Fin
On venthole air can be made to flow to another gas chamber from a gas chamber, make each gas chamber pressure keep balance.
There are two types of methods for the directional control of conventional ram-type parafoil: the first is that one side rear is pulled down by control wire；The
Two kinds are to close the several air inlets in outer wing side with control wire, so that the unilateral outer wing of parafoil be made to roll over.But two kinds of method of operating
There is shortcoming: when using the first directional control mode, it may appear that some adverse conditions: as when pulling one side rear
When, the lift of the flank face increases, but resistance increases faster.Lift increment generated in transverse plane it is a kind of sidewinder become
Gesture, and augmented resistance then mainly causes the yaw rate in a course in the horizontal plane, therefore the angular speed yawed compares rolling
Angular speed becomes apparent from.When yaw rate reaches certain value, the difference of the effective speed and effective angle of attack that make aerofoil both sides is arrived greatly
To a certain degree, enter unilateral aerofoil stall conditions.Further, since reversely sidewindering the presence of trend, manipulation is made to seem not clever enough
Work tends to form manipulation excessively entrance spiral stall campaign.Although second of method of operating safety is relatively good, right
When large area throwing object parafoil carries out directional control with the method for closing outer wing part air inlet, steering force and manipulated variable compare
It is small.
Utility model content
In view of this, the present invention provides a kind of double-vane umbrellas, and the folding and unfolding by controlling parafoil controls its heading, and
Parafoil area can be changed according to actual demand, to meet the flight lift resistance ratio, glide ratio and flight demand of different weight load, tool
Standby preferable lift resistance ratio, handling and stability.
The double-vane umbrella includes: extendible connection device and is connected to rushing for the extendible connection device left and right ends
Pressure type parafoil；Each parafoil passes through the parafoil control wire group being attached thereto and is connected with load storehouse；
The extendible connection device includes: fixed bracket and the parafoil reel positioned at the fixed bracket both ends；Each institute
It states parafoil reel and connects a parafoil；The parafoil reel rotates under the drive of power unit, to realize to being attached thereto
The folding and unfolding of parafoil.
Preferably: parafoil reel connector sleeve, the parafoil reel being set with the connecting pin of parafoil reel on the parafoil
Connector sleeve and parafoil use same material that one is made, and the parafoil reel connector sleeve is sleeved on outside the parafoil reel, energy
It is enough to be rotated under the drive of the parafoil reel.
Preferably: being connected in the setting length range of one end on the parafoil with the parafoil reel and be not provided with parafoil behaviour
Vertical rope.
The utility model has the advantages that
(1) traditional parafoil is compared, the double-vane umbrella of the utility model improves lifting capacity, and two parafoils can be mutual
Backup, further increases safety.
(2) by carrying out individual folding and unfolding and control to each parafoil, the lift resistance ratio of each parafoil can be changed, to control
Multiple wing umbrella heading；By adjusting each parafoil area, meet the flight lift resistance ratio, glide ratio and flight need of different weight load
It asks.
(3) parafoil rope is not used in parafoil reel connector sleeve setting length range, thus, it is possible to not change parafoil
Change parafoil area on the basis of aerodynamic configuration, realizes the fine tuning to parafoil area.
