Abstract: FIELD: rail tracks. 
     SUBSTANCE: invention can be used in any industry employing rail vehicles. In proposed joint rails are connected to each other by side fishplates and cross fastening members. End faces of each butt joined rail are made axially symmetrical at angle to longitudinal axis of rail. Surfaces of rail butt joints are inversely symmetrical to perpendicular to longitudinal axis of rails. Length L of side fishplate is calculated by formula: L=K B/tgα where B is width of rail head; α is angle of symmetry of cut plate relative to longitudinal axis of rail: K=1.5 … 3 is coefficient found experimentally. Invention provides increasing of active zone of wheels passing through butt joint and simultaneous decreasing of cantilever non-fastened zone of butt joint, thus reducing dynamic loads acting in butt-joint and on permanent way. Use of proposed rail fishing reduces specific amount of metal per structure and total weight of rail track owing to reduced length of side fishplates. 
     EFFECT: increased service life and improved reliability of butt joints.

Abstract: FIELD: the invention refers to aviation technique. 
     SUBSTANCE: the mode envisages measuring of vertical acceleration and with the help of a sensor of static pressure- the indicated barometric altitude. The values of the vertical speed are received by way of integrating a vertical acceleration, the values of the barometric altitude - integrating a vertical speed with the calculation of corrections of acceleration and speed. The difference between computed and indicated barometric altitudes with calculation of delays in the pneumatic tract of static pressure is used for computing mentioned corrections using coefficients. The atmosphere is sounded no more than 3 hours before flight tests which are carried out on regimes consisted of sectors of horizontal flight, climbing and lowering. At that vertical acceleration, indicated barometric altitude, reference vertical speed and geometric altitude of a flying vehicle are synchronously measured. Using these parameters the model values of vertical speed and barometric altitude are computed on the basis of Kalman's filters and coefficients are optimized minimizing the criterion of quality: the mean value of the square of an error or the maximum value of the module of an error of defined magnitude. The delay in the pneumatic tract is defined by calculation of pressure and temperature of air at the present altitude. 
     EFFECT: increases accuracy of definition of vertical speed and barometric altitude of the flight.
