Sumbaev 3 July 1992 4 July 1992 R E P O R T N 20/92 on extrasensory works on extrasensory analysis of the technological processes on the part of special coatings in the shop N 5 of the plant 243 of Civil Aviation, carried out by Grigoriy Petrovich Grabovoy in June 1992 We, the undersigned, the executor of works the extrasense G.P. Grabovoy and the representatives of the Customer: a deputy chief production engineer of the motor complex of the plant N 243 of Civil Aviation A.I.Pyryev, a team manager of general technologies of the motor complex of the plant N 243 of Civil Aviation F.T.Kirillova, a head of the engineering and information centre of aviation and technical base of the National Airline of the Republic of Uzbekistan V.M.Saulkin and a senior project engineer of the engineering and information centre of aviation and technical base of National Airline of the Republic of Uzbekistan S.V. Nemtzov, drew up the present report that Grabovoy G.P. in June 1992 carried out undermentioned extrasensory works on the agreement N 9 of 02.12.1991 between the joint Soviet-American enterprise "ASKON" and the Uzbek Department on Civil Aviation on the subject "Non-traditional methods of aviation technique diagnostics". G.P.Grabovoy carried out the work on extrasensory analysis of causes leading to the occurence of defects on the compressor stator units of high pressure after the application of the sealing coating 18 VK-2G. The team manager of general technologies F.T.Kirillova set up a task to G.P.Grabovoy to determine the cause of rejects at the following technological process: at the part of special coating in the shop N 5 the sealing coating 18 VK-2G is applied to the compressor stator units of high pressure to accelerate air the flow-over from the cavities. The most frequent defect: - scalling (plus material, shearing) of the special coating of the metal after the final operation. Attendant defects: - spilling of the special coating. G.P.Grabovoy gave the following information got by the help of his clairvoyance: 1. Depending of the season and storage condition of the adhesive before the transfortation, the supplied adhesive has quality not corresponding to the application conditions. 2. At the sand-blowing treatment the microparticles of silicon base, were not completely removed, which have coefficient of temperature expansion below than the binder of special coating, around them. Due to this at the thermal treatment (at the final stage) the deformation of the special coating adhesion surface with metall, occured leading to the fracture development. Sheet N 2 Report N 20/92 3. The relative humidity of the graphite powder is not regulated. Due to this the surface microfractures of the special coating occured, leading to the decrease of special coating resistance to mechanical actions. If the graphite powder humidity is overstated than large-size fractures will appear. Precise humidity of the powder prevents the development of indicated microprocesses. 4. During 2/3 of the work of the sector the disperity between the speed of the compound solidification and qualitative solidification process is observed. 5. In 20% of works, carried out during first two quarters of 1992 the alcohol is understated. 6. There is no link between the qualitative compound of the supplied adhesive and viscosity of prepared ground. Depending on physical and chemical properties of the adhesive viscous characteristics of the ground should be varied together with the graphite particles size. 7. At the manual application of the special coating parts non-unirform by thickness and adhesion degree with the unit surface is allowed. Due to this speeds of solidification and drying of various special coating zones differ. Dried and extanded special coating parts, having less thikness and larger adhesion degree with the unit surface, displace along the borders parts of the special coating, having larger thikness. Due to this the increased material deformation occur along the areas borders. It leads to that average coefficients of heat tansfer of given areas differ by absolute value and are anisotropic. Thus thermal expansion coefficients as well as linear expansion of considered areas differ. Thus thermal stresses and deformation causes mutual transfer of nonuniform parts, leading to the destruction and rupture of required uniformity of the driev coating in the places of the higher shift deformation. Recommendations by G.P.Grabovoy on this item: At the mechanical application of the special coating along the spiral with subsequent thikening the volumetric expansion of the material takes place without the rupture of the mechanical properties of the material. 8. Coating thikness is high. Thus the overdrying of the open coating surface takes place and loosiness occurs. Due to the non-correspondance of coatings thikness to the outer thermal field fractures occur. 9. Induction furnace for the working ring of the control of high pressure: Indications of temperature from the control ring doesn't correspond to the real temperature on rings: - there is no uniformity of convection heat emission due to which the groups on rings reach 15-17øC. 10. The induction furnace for drying working rings of contour of law pressure: - uneven distribution of electromagnetic field; - thermal differences on working rings up to 30øC; - uneven drying of the working coating with hidden places of wetting. 11. A furnace for drying of guiding devices without the forced ventilation: Sheet N 3 Report N 20/92 - uneven distributed field of temperatures due to the heater location and geometrical furnace sizes (recommendations: the thermal field should be dissipated and made uniform at the expense of increase of the furnace volume and creation of additional heat capacities from the heater spiral). 12. The furnace for drying guiding devices with the forced ventilation: - the air supply speed is overstated. 13. The universal furnace N 1: - the arrangement of the thermocouple in the furnace doesn't allow to objectiely reflect the thermostating; - the readings on the sensor delay. The process in the furnace proceeds quicker and has considerable deviations from the sensor indications by time in the thermal shock regime: - due to the natural convection the areas, having considerable temperature gradients are being established. 14. Universal Furnace N 2. - analogous to 4th furnace but more farourable temperature field near the door. 15. Sometimes shock above the tolerance limit on the boring place. 16. The shortening of the technological process by time is allowable. 17. Technology of adhesive composition VK-2 is distored: 1. Varnish KO-019-MPTU6-02440-67 has no constant viscosity. 2. Paraform MPTU6-05-980-65 has varying qualitative composition. 3. Asbestes of the grade M-5-65 GOST 12871-67 has tensile strength less or above the standard, asbestes fibers dimensions are not precisely maintained. 4. Ethyl alcohol TU 084-337-72 used in lower quantities. 5. Foreign powdery asbestous admixtures, pollutant, deteriorating the adhesive composition are available in the adhesive. The specialists of the plant were informed on the results of the work and they were discussed on the meeting of the main specialists of the shops N 4 and N 5 of the plant 243 of the Civil Aviation on 17.06.1992. According to the conclusion by the expert of the team manager of general technologies F.G.Kirillova: "Despite the fact the extrasensory diagnostic of the technological process was carried out by G.P.Grabovoy wihout the technical documentation, the analysis of defect causes was carried out thoroughly and precisely and in items it coincides with the opinion of the designer's supervision commission, the clairvayance level of G.P.Grabovow allow to carry out deep research works, where the vision of microprocesses is required, which couldn't be seen with the help of microscope". The introduction of one of the recommendations by the G.P.Grabodoy of the item 10 in July 1992 allowed to practically eliminate rejects on this line. The thermostatic device was introduced, which allowed to have averaged characteristics of the electromagnetic field. To eliminate the temperature difference on rings and provide the uniform drying of the working coating could be achived at the expence of increase of areas of contigous surfaces of the ring and thermocouple. As a result upon the conclusion by the foreman of the section of special coatings A.V.Rodionov: "If previously from 14 working contour rings of later pressure 8-9 rings passed the quality control, now practically all from 14 pass the control". Sheet N 4 Report N 20/92 Thus the elimination of faults, detected by G.P.Grabovoy allowed to normalize the conditions of rings drying and to eliminate faulty production in practice. Taking into account the high efficiency of introduction of recommendation by G.P.Grabovoy, the extrasensory diagnostics can by used for correction of technical processes with the purpose of economies of labour and valuable materials as well as increase of works efficiency.
