Gantry crane mounting method and gantry crane mounted according to this method Two mounting gantries (1) and (2) are used at gantry crane installation, prior to lifting of a crane longitudinal girder (3) guide apparatuses (10) are attached to it by mounting hinges (9), ends of bars (11) are pivotally connected to the guide apparatuses and their other ends are pivotally connected to balance trolleys (8). Sections (13) of which supporting poles consist are installed by one in each guide apparatus and attached to them, the longitudinal girder is lifted by strand jacks (6) to the intermediate position - up to the vertical position of the said sections of the supporting poles. Truss systems (14) are mounted by coupling the bars with the guide apparatuses, with each other and with the balance trolleys. Afterwards the mounting gantries are demounted, the strand jacks are installed on the guide apparatuses, strand jack cross members (7) are put under the lower parts of the sections, the sections are disconnected from the guide apparatuses and moved by the strand jacks. Then the lifted sections are fixed in respect to the guide apparatuses, the upper parts of the next supporting pole sections are attached to their lower parts, the strand jack cross members are put under their lower parts, the sections are disconnected from the guide apparatuses and with their help the supporting pole sections are moved together with the longitudinal girder into the next intermediate position. A gantry crane comprises a longitudinal girder with at least one hoisting trolley installed on it and two supporting poles resting against two balance trolleys each. Each supporting pole consists of several rigidly intercoupled vertical sections, a guide apparatus for the supporting pole sections and a truss system comprising two bars pivotally connected to the guide and the balance trolleys, cross beams coupling the bars, and diagonal braces coupling the bars with the cross beams. The upper sections of the supporting poles are attached to the longitudinal girders and their lower sections are attached to the guide apparatuses. |

Stringer panel from laminar composite Stringer panel forming the skin and stringers from alternating monolayers of composite arranged in lengthwise direction along said stringers. Stringer cross-section features wavy shape. Stringer is divided into first part starting in skin depth and formed by extra lengthwise monolayers, second part with shin transverse monolayers are laid in separate strips, and third part formed by lengthwise and crosswise stringer monolayers above the last top layer of the skin. Crosswise monolayers extend to wave edges to overlap underlying crosswise monolayers Layers at stringer cross-section mid part can be made horizontal so that wave top has smooth horizontal section. |

Method of guiding aircraft to ground object Invention relates to autonomous aircraft navigation systems, particularly aircraft navigation systems comprising on-board radar equipment which guides the aircraft to ground objects. Guiding an aircraft to a ground object includes measuring the viewing angle of the ground object in the horizontal plane relative to the direction of the ground velocity of the aircraft, the angular velocity of the line of vision of the ground object in the horizontal plane, the distance from the aircraft to the ground object, the flight velocity of the aircraft and acceleration thereof in the horizontal plane. The method also includes measuring the current value of the deviation angle of the line of vision of the ground object from the direction of the velocity vector of the aircraft, the current value of the viewing angle of the ground object in the vertical plane, the current value of the inclination angle of the velocity vector of the aircraft in the vertical plane, the current value of the angular velocity of the line of vision of the ground object in the vertical plane and the current value of acceleration of the aircraft in the vertical plane. The method includes calculating the current value of the deviation angle of the projection of the line of vision of the ground object on the horizontal plane from the projection of the direction of the velocity vector of the aircraft on the same plane. The obtained results are used to control flight in the horizontal and vertical planes to enable stabilisation of the linear azimuthal resolution of the radar image of the ground object generated by on-board synthetic aperture radar, stabilisation of resolution of said radar image on the horizontal range, and such that the direction of the velocity vector of the aircraft in the vertical plane at each moment in time matches the direction towards the point of intersection of the perpendicular to the horizontal projection of the line of vision of the ground object, passing through said object and belonging to the horizontal plane, with the vertical plane to which the velocity vector of the aircraft belongs. The value of deviations (discrepancies) of current angle measurements, as well as the current inclination angle of the line of vision of the ground object from the required values is estimated and trajectory control signals for the aircraft in the horizontal and vertical planes, which enable to eliminate said deviations, are generated. |
