Description
Technical field
The present invention relates to a kind of method for folding of solar sail sail face, relate in particular to a kind of method for folding that is applicable to square sail that sail face is piecemeal, adopts the strut bar type solar sail sail face of 5 connections.
Background technology
Solar sail is to utilize sunshine to compress into the cosmonautic aircraft of row.In ideal conditions, Solar sail spacecraft is without any need for fuel, and it can obtain lasting thrust and fly to cosmic space from inexhaustible sunlight.As long as shape and inclination angle are suitable, solar sail can fly to including any direction towards light source, has great preceence aspect survey of deep space.At present, the research of solar sail correlation technique has all been carried out in the U.S., Japan, Russia and Europe.
Photon strikes solar sail face is also reflected back completely, solar sail is produced to antagonistic force promotion solar sail and carry out space travel, in order to make solar power that enough optical pressure are provided, solar sail must capture sunshine as much as possible, and this area that just means sail must be enough large; In the time of transmitting, because emission space is limited, need again solar sail to be stored in less space.Therefore, need to reasonably fold the sail face of solar sail, to ensure the smooth expansion in space after solar sail injection.
Solar sail has multiple mode classification: according to sail face shape difference, can be divided into square sail, circular sail and leaf sail; According to expansion mode difference, can be divided into spin deploying solar sail and strut bar type solar sail, spin deploying solar sail utilization spin centnifugal force is realized the expansion of sail face and the maintenance of sail face shape, and strut bar type solar sail is that expansion and the shape of utilizing strut bar to realize sail face keep.Solar sail sail face shape is huge, conventionally piecemeal is manufactured to sail face.For square strut bar type solar sail, conventionally along the diagonal of square sail, sail face is divided into four isosceles right triangle sail faces and manufactures respectively, be called the solar sail of sail face dividing.To the square strut bar type solar sail of sail face dividing, strut bar has two kinds of conventional connection modes with sail face: the first connection mode is that four summits of square sail face are connected with strut bar respectively with center-point, be called 5 connections, it is folding respectively that this connection mode is conducive to sail face and strut bar, too much phase mutual interference while having avoided launching; The second connection mode is not only connected with center-point four summits of sail face with strut bar, and sail face edge and strut bar adjacent are carried out to multiple spot be connected, sail face is connected as a whole with strut bar, this connection mode requires sail face and strut bar to cooperatively interact when folding, and the two also can disturb upon deployment.
Japan IKAROS launched in May, 2010, had successfully realized the expansion in-orbit of solar sail.It folds the entirety of solar sail face, utilize spin centnifugal force to realize the stepwise development of sail face, but this folding mode is only applicable to whole square sail face to carry out, and manufactures for sail face dividing, respectively folding solar sail being not suitable for.The U.S. also successfully enters near-earth orbit and has carried out launching experiment in the NanoSail-D solar sail of in November, 2010 transmitting.NanoSail-D sail face adopts piecemeal manufacture, four sail faces carry out respectively simple vertical Z-type folding after, then twist in together on the spool that is positioned at solar sail center 5 connection modes of strut bar and the employing of sail face.Under the pulling force effect of strut bar, sail face launches rapidly, but is only applicable to the sail face that area is less, and the situation that sail face is piled up appears in the expansion initial stage, large area solar sail is launched to the situation that the initial stage likely occurs that sail face is wound around at sail face, hinder the further expansion of sail face.
Due to solar sail configuration difference, and sail face adopts foldable integral or the folding difference of piecemeal, and the applicable folding mode of sail face is also different.For sail face dividing and large-scale square solar sail folding, that utilize strut bar to launch respectively, do not have at present better suited folding mode to make four solar sail faces can synchronous stable expansion in order under the effect of strut bar pulling force.
Summary of the invention
The technical matters that the present invention solves is: overcome the deficiencies in the prior art, a kind of method for folding that is suitable for the square strut bar type of piecemeal solar sail sail face is provided, solve sail face dividing, adopted the folding problem of the large area strut bar type solar sail sail face of 5 interconnection systems, folding mode is simple, expansion process steady ordered, has improved reliability.
