Abstract
A pseudo-ornithopter features that multiple arc flaps are paired and then serially linked to a central vertical axle, and under the drive of power, they are fastly and continuously moving up and down relatively by the same stroke to compress the air for generating the lifting-up force.
Description
The present invention relates to the paired loose-leaf frame that a plurality of camber loose-leaves of a kind of usefulness are formed, under power transmission, make the vertical compressing air that falls to moving that rises of rightabout relatively high speed and produce the lasting lifting force of similar birds flapping wing vibration.Belong to a kind of new flying method in the aeronautical technology field.
The mankind have three kinds of flying methods at present: a kind of H of being
2He
2The flight of air bag; The 2nd, wing is the flight of draught head up and down; The 3rd, the screw propeller flight that air produces lifting force of cutting sth. askew.But all mechanism's heaviness only is applicable to relatively large flight.And people also very envy that the flapping wing of birds circles in the air, and the dream power consumption is very low, and are free brisk, promptly play the sole flight who promptly falls.The long-term trials that come many people also once to make the flapping flight of various imitation birds all end in failure, but never find out the basic reason of its failure.In fact, this reason is very simple, be because exist intermittent factor in the flapping wing activity of their made, thereby acceleration due to gravity has played interference effect and become invalid fluttering.So this only is a design-calculated thinking problem.
Purpose of the present invention is exactly: provide a kind of double-type, do the vibration that falls of the vertical equidistant liter of relative high speed on string one vertical pivot, the loose-leaf frame of being made up of most camber loose-leaves (idol is apart from moving).The nothing that can produce continue lifting force intermittently overcomes the effect of acceleration due to gravity, makes the method for the technical pattern that carrier takes off.Set up the mode of human the 4th kind of flight.
The object of the present invention is achieved like this: this " couple distance moving arc type rotor aircraft alive " is by lift portion, and driving section and power part three are partly formed.(1) lift portion is by a pair of or several the loose-leaf frame is formed, and the loose-leaf frame is square, and the lower edge, shirt rim is arranged all around, to increase downward air overall resistance when movable.Be made up of a plurality of open downwards camber loose-leaves in the loose-leaf frame, the arc concave surface is downward, Yi Bian be fixed in line on the hinge strap on the frame.All each is fixed on the pulley frame in central part every pair of loose-leaf frame, has the pulley wing of riding pulley of two phase contrapositions to clip vertical pivot in the pulley frame, and this rolling touch had both guaranteed that relative position was constant, and extremely low-resistance rises activity flexibly up and down again.When a loose-leaf frame rose, wherein each loose-leaf was subjected to deadweight and air resistance open downwards, but restricted rope pins down only open 30 °-45 °, its below of inrush of air.Simultaneously, another loose-leaf frame is done to fall relatively, wherein each loose-leaf is subjected to air resistance folded mutually rapidly closed to the lower compression air, produce certain resistance, this resistance is exactly to be equivalent to the life force amount of air to the loose-leaf frame, the area size of this life force amount and loose-leaf frame, square being directly proportional of double-type number and the speed (being decided by frequency and stroke) that falls.When dropping to stroke, a loose-leaf frame closure to begin to go up long the liter finally, double-type another loose-leaf frame just in time rises to the stroke top to begin to fall, the mutual crop rotation of a pair of like this loose-leaf frame, formation is to the lasting compressing of air, less than intermittence, just overcome the interference of acceleration due to gravity, produce the life force amount that continues, carrier is taken off.
The linear velocity of loose-leaf frame is v=2UL, and U is crank wheel gyrofrequency (inferior/second), and L is the stroke of per semiperiod of loose-leaf frame, a pair of loose-leaf frame * 2,2 pairs of loose-leaf frame * 4.
Air lift force F=1/2Cr ρ Sv
2Cr is that drag coefficient (camber loose-leaf+shirt rim) is 2.5-2.8, and ρ is density of air=0.00125, and S is 1 loose-leaf frame area,
According to estimation: each 2m of a pair of area
2The loose-leaf frame, each stroke 0.5m, frequency 60 times/second (shaking like the hummingbird wing) can make the carrier of 112kg, takes off with the speed of per second 10cm, and power W=FV=9H
p=6.6k
w
If with area loose-leaf frame, lifting force just can increase by 4 times with two pairs of vertical pivots.Power needs power to increase by 8 times.Just can increase by 9 times as 3 pairs with area loose-leaf frame lifting force, and the power of power increasing by 27 times, is how to have lacked than the consumption of power of autogyro.The camber loose-leaf is small and dense under the constant situation of the loose-leaf frame gross area, and effect can be better.Certainly, because the vibration of loose-leaf frame high-frequency high-speed, high requirement is proposed also for intensity, material and the technology of structure.Modern industrial technology can be accomplished fully.Can be with screw propeller or gas ejector pipe method as for the mode of aloft advancing after rising.
(2) driving section mainly is by vertical pivot, pulley frame, drag-line, crank wheel, ring gear, compositions such as fixed pulley.In the middle of the loose-leaf frame oblong Main subrack is arranged, be fixed between the outer upper and lower sleeve frame of pulley frame.The a pair of pulley of riding is arranged in the pulley frame, ride the pulley both wings and just in time clip vertical pivot relatively.Pulley frame one side has pull bar and La Quan, fixedly makes transmission traction with drag-line.Drag-line rises from drawing of a side crank wheel outer ledge prominent, upwards be upward through again draw circle fixing with side lower pulley frame after upper pulley frame walk around again the top fixed pulley turn to down upper pulley frame below offside draw circle fixing after be passed down through again that the next pulley frame terminates in 180 ° of phasic differences on the offside crank wheel another draw dash forward on.
Because drag-line interlock two crank wheels have one " length difference ", its length be equivalent to draw prominent garden Zhou Yundong radius 1/2.The height that can compress suitable 1/4 radius of fixed pulley between vertical pivot top and fixed pulley when therefore, having spring compressor (stage clip) to make the drag-line motion gets final product.
The bottom of vertical pivot is an axle bed, by company's rotating shaft that its head bearing passes across, ring gear and both sides crank wheel is connected.
(3) power part can be a spark ignition engine, and electrical motor etc. are as long as the driving gear of engine drives the ring gear motion by chain.Certainly also can use the wheeled transmission of belt under some situation.
Be example with a pair of loose-leaf frame below, the invention will be further described in conjunction with the accompanying drawings and embodiments.
