Abstract: FIELD: transport engineering. SUBSTANCE: proposed system contains support frame 11 formed by two legs 17, 18 hinge intercoupled for turning around two end axles 21, 22. Two inclined guide rollers 14 moving along guide rail 8 are installed on each leg. Support frame 11 is installed for displacement in longitudinal direction relative to wheel axle of vehicle, thus providing reversing of automatically controlled movement under action of power reversing drive 15. Support frame 11 can be lifted by lifting mechanism acting onto levers of support frame after releasing of guide rollers 14 from contact with guide rail 8. Wheel axle is automatically controlled in direction of movement by means of subsystem 9 operated by support frame 11. Controlled subsystem 9 provides possibility of deflection in cross direction from behind around point of turning located in close vicinity to front guide rollers. Proposed possibility of reversing is expedient for vehicles whose movement is controlled by guide rail. EFFECT: prevention of derailment of guide rollers from guide rail in motion. 20 cl, 12 dwg

Abstract: FIELD: space engineering; methods of control of spacecraft in near-round orbit. SUBSTANCE: proposed method includes separation and removal of spacecraft from space object. After separation, position of manned spacecraft is noted and removal pulse is furnished. Then local vertical coinciding with axis of visual observation is plotted by performing successive turns of manned spacecraft around their own axes perpendicular to axis of visual observation. Then, angle of turn of manned spacecraft relative to last axis is determined which is necessary for plotting orbital system of coordinates on board manned spacecraft. After turn through said angle, correction pulse is furnished in direction of orbital velocity if angle is lesser than 90 deg. or opposite orbital velocity if angle exceeds 90 deg. Magnitude of correction pulse is selected by static simulation such that ensuring guaranteed distance between manned spacecraft and space object in free flight and in sending deceleration pulse for orbital departure of manned spacecraft. Proposed method ensures autonomous departure of manned spacecraft from nonoriented space object at absence of information pertaining to their relative position reducing time required for correction at guaranteed safety for objects at all stages of maneuver.

Granted: 2003-10-10
Abstract: FIELD: thermal physics; investigation of fuel element temperature conditions in nuclear reactors. SUBSTANCE: existing fuel assembly has shroud, top and bottom current leads with fuel-element simulators in-between electrically connected to top current lead via flexible electricity conducting links disposed in can. Main disadvantage of such fuel assembly is that its power is limited due to the fact that outer (inner) diameter of can is limited by simulation conditions. That is why cross-sectional area of flexible link is also limited and depends on locking conditions of the latter within can during its chaotic displacement. Novelty is that top current lead is provided with locating pins with flexible electricity conducting links wound thereon and simulators are provided with blind holes in their upper parts to ensure movable connection of simulators to top current lead during their thermal displacement. These measures provide for enlarging sectional area of flexible current conducting links and raising current through them and, hence, through simulators and fuel assemblies. EFFECT: enhanced power of fuel assembly at same simulation conditions. 1 cl
