Abstract: FIELD: geophysical survey of wells. SUBSTANCE: used for the purpose are three gradient sondes of different lengths. Long and medium-long gradient sondes are installed so that their current electrodes are located in common point. Short gradient sonde is located relative to long gradient sonde so that their corresponding measuring sondes in lower point of measurement of long gradient sonde are found at same level. Measuring electrodes of all three gradient sondes are sued for measurement of density of currents at different distances from common pint. These values are used in reduced state with consideration of difference of distances between measuring electrodes. In addition, based on value of current density of long gradient sonde in reduced state is determination of value of current density with consideration of change of current density of section between points of location of its measuring electrodes. Then, obtained values of current density in point of measurement of long and medium-long gradient sondes are used for determination of ratio of value of current leakage into rocks between points of measurement of long and medium-long gradient sondes to value of current directed into well below location of long gradient sonde. This ratio is proportional to ratio of conduction values of rocks and well which are converted into ratio of resistances. Judgment on rock electrical resistance which is converted into resistivity with consideration of coefficient of cylindrical sonde is made by change of ratio of resistances at constant resistance of well. EFFECT: more accurate values of rock resistance due to consideration of possible disturbance of uniform distribution of current. 3 cl, 3 dwg

Abstract: FIELD: methods of starting aircraft turbo-jet engines. SUBSTANCE: proposed method consists in actuating the starter, connecting its shaft to engine rotor and disconnecting starter shaft after developing required rotational speed by rotor. In an emergency in case of failure to start engine in flight, as well as in conducting ground tests, starter shaft is disconnected from engine rotor and starter is shifted to operation in mode of auxiliary power plant. Under standard conditions, cartridge starter is used for starting the engine or for conducting the ground tests. In an emergency, cartridge starter is used in parallel with gas-turbine starter. Cartridge starter is also used in zone of non-guaranteed start of gas-turbine starter. Proposed method makes it possible to start engine practically under any conditions on ground and at any altitude in flight, thus enabling the pilot to orient aircraft to zone of probable ejection. EFFECT: enhanced efficiency and reliability. 1 dwg
