   On the basis of seismic air gun "GEOKHI-PNEUMATIC" (three variants) and "GEOKHI-PROPAN", used as the pneumodrive, is developed a number(line) of the constructive circuits: "GEOKHI-KAVITONE", "GEOKHI-TONE" (two variants), overlapping a wide range of a video - and tone-pulse of signals of geoacoustics in a range from unfro- up to ultrasonic frequencies of a spectrum. Thus the constructive decisions allow:

• To unite all air gun in one module with съемными by elements;
• To develop four separate of a number(line) (on number of base pneumodrives) till four излучателя in each number (" … PNEUMATIC", " … KAVITONE" "… TONE -1 ", " …TONE- 2 ");
• To connect same air gun (on base " … PNEUMATIC ") in linear groups to a feed(meal) from one source of the compressed gas; Cubic centimeter;
• To realize излучатели with minimal volume of pneumochambers (Up to 1 с.см. аnd less – Small depth) And superlarge volumes (Up to 200-500 c.dм.- and more seismological tasks);
• To realize (with a pneumodrive " and "GEOKHI-PROPAN ") effective radiation in conditions of the superlarge pressure of an environment (Deep chinks, large depths of the sea);

   The basic application of development is connected to areas of a seismoreconnaissance and hydroacoustics more in detail see tab. 1 , additional - in sphere of formation of intensive sound and ultrasonic fields with the purpose интенсификации of technological processes in industries:

• chemical - acceleration of processes полимеризации, flotation;
• food - acceleration of processes;
• oil-extracting – vibration- influence on a petroleum layer, сlearing of chinks;
• building industry - hardening of concrete;
• sea fishery - attraction, scaring away at fishery.

   perspective and problem areas of application:

• the economic, power-intensive engine of internal combustion on base "GEOKHI-PROPAN";
• remote suppression of fires on base "GEOKHI-PNEUMATIC", by means of formation of a beam of carbonic gas.

   In comparison with air gun of a world class, for example, design of firm "BOLT TECHNOLOGYE CORPORATION" USA, the design "GEOKHI-UNISIGNAL" is much more effective.

   General(common) constructive elements of the best prototypes air gun are: chambers of accumulation and preliminary explosion-return-braking, the element, opening the working chamber, is executed as a massive piston body, making reciprocating movement between chambers, In one of extreme rules(situations), locking the working chamber, in the friend, her(it) opening. The realization of the compressed gas on environment(Wednesday) occurs through a narrow backlash between a piston body and chamber of accumulation, that results in essential losses of the reserved energy and low seismic efficiency of generation of a sound. Thus the radiation is carried out extremely in a seismic range of frequencies 5-300 Hg.

   In an offered design the chamber of accumulation is formed(educated) by opening elements, executed as mobile rings, at сompression which to each other there is an accumulation of the compressed gas, at separation раздвижении his(its) realization on environment(Wednesday). At the expense of this constructive decision is reached(achieved):

• increase of the area выхлопа and volume of a sold working body;
• increase of durability of a design;
• the minimal metal consumption;
• easy adjustment on a type of a signal, frequency a range (1-50 000 Hg), the purpose spatial - temporary groupings, at the end, soluble geological task.
• at use of a pneumodrive "GEOKHI-PROPAN" - failure(refusal) of expensive compressors, opportunity of work at low temperatures and on small courts, preservation of serviceability at superhigh pressure of an environment;

   The expansion frequency of a range in area of acoustic voice-frequency-pulse signals on the basis of a pneumodrive is carried out for the first time. Thus the effective generation of signals of this type and in "dead" for (electro) of hydroacoustics to a strip of frequencies 500-2000Hg is provided. (and is lower). The development of this range of signals can result in unique achievement in development of the precision equipment for geoacoustics and results of researches. And by virtue of the high power characteristics source of a voice-frequency type (factor of which capacity can be finished till 80-90 of % and above) the low-frequency parametrical aerials for deep sounding of ground and communication (connection) in a seismological range of a spectrum can be developed.
