Description
Technical field
The invention belongs to spacecraft in-orbit services and maintenance technology field, are related to a kind of flexible expansion mechanism.
Background technique
Geostationary orbit (GEO) is the important Earth's orbit resource of the mankind, and in-orbit resource is limited by rail position, extremely tightly
It lacks.It is uncontrollable comprising 40% or more in the population of satellite of GEO band (GEO ± 200km) however as the rapid development of space mission
Or discarded satellite and its remains, these space objects period of passing away naturally is long, to the safe structure of the GEO satellite of normal operation
At threatening, also lead to GEO rail position resource serious waste.Another statistics shows in the in-orbit GEO satellite to break down, 50% with
On the source of failure lost in a certain function of service system, and occupy the payload and main platform body of 70% or more satellite cost
Function is intact.Therefore, it needs to develop a kind of servicing aircraft for carrying general capture mechanism, auxiliary is still trapped in GEO band
The completion of discarded satellite leave the right or normal track operation, be pushed into GEO rubbish track；Or fault satellites are implemented to rescue, quickly defend failure
Spaceborne lotus task ability is continued.
For in-orbit inert satellite, in terms of attitude characteristic, due to energy dissipations such as celestial body solar wing and propellant sloshings
Effect, in the case where angular momentum is certain, according to that can converge concept, satellite will finally rotate (usually east around the maximum principal axis of inertia
West to over the ground to), and the moment of face such as solar light pressure effect under, there is more small size nutating；In terms of interface features, at present
It is in-orbit and be not directed in the GEO satellite ground and receive in-orbit service and Maintenance Design, do not have the mating interface of cooperation.Therefore,
In conjunction with the rescue service to such satellite and the operational requirements that leave the right or normal track, need to design small-sized just suitable for the big tolerance of high rail satellite
Property arresting agency, increase the versatility arrested, reliability and safety to satellite in orbit.By being set to high the general of rail satellite
Back-up analysis, satellite north north direction install the solar battery array of expansion, are equipped with star interface butt joint ring in satellite-rocket docking face
With apogee engine, antenna is installed to ground in satellite.Wherein, apogee engine no longer makes after satellier injection work
With, be suitable for be selected as satellite arrest docking object.
Apogee engine is arrested based on cone lever type mechanisms, is particularly suitable for discarding around the high rail rotated to axis over the ground and defend
Star can make full use of the weak stroke speed between two aircraft, carry out isotropic guiding by engine inner conical surface and arrest,
Reduce the relative pose control precision of two aircraft.
Currently, external typical research approach include U.S. phoenix in the works mechanical arm+replaceable end effector scheme,
German DEOS and Europe SMART-OLEV bores rod-type arresting agency scheme.Cone rod-type arresting agency therein is defended mainly for GEO
The general apogee engine of star is arrested, which is composed in series by telescoping mechanism and cone linkage, and telescoping mechanism is realized
The axial stretching movement for boring linkage, bores linkage by coronal extension retaining mechanism, tip sensors in place and combined laser
Sensor composition, coronal extension retaining mechanism therein are also to be captured for engine trunnion.Regrettably, at the mechanism
In the outside of arresting agency, do not have Telescopic, during to satellite capture, it is possible to first hit the part body without
It is the external orientation structure for boring linkage, be easy to cause the damage arrested failure or even cause coronal extension retaining mechanism.
For the docking of arresting of satellite, the domestic Chinese Academy of Space Technology and Shanghai Academy of Aerospace Industry etc. focus mostly on for closing
Make the Space Docking Mechanism research of satellite or manned space flight.It is designed in docking mechanism seminar's early period that arrests for grinding satellite in-orbit
A kind of general arresting agency of weak shock and its pawl swelling device (201410783968.6 He of ZL suitable for high rail satellite
ZL201410785009.8), which is driven using linear motor, is based on pawl swelling device, and essential core drives parts
Axial arrangement, overall structure is oversized, and flexible and swelling process motor needs positive and negative rotation campaign, defines and arrests speed.
