- the handle gripping of the modular cylinder head housing facilitates introduction and especially extraction after operation of the gas generator in its combustion chamber.
- the caliber of the launch tube is adaptable to the diameter the projected tool or its tool holder thanks to the introduction and locking in position of additional tubes small diameter inside the launch tube.
- the launch tube is equipped with vents side which allow to eject, after the passage of the tool piston, gas up in chamber annular which constitutes a silencer inside the frame of the device according to the invention.
- the launch tube and its ballast or mass structure ballast are free to back up vertically and this decline ensures, under the effect of gravity, balancing the amount of movement applied to the piston and to the projected tool.
- Adaptation of the jacking speed, the holding force applied to the launch tube and its ballast structure and return speed of the launch tube and its ballast structure is made using calibrated single or double pass vents and cylinder inflation pressure.
- the percussion release system is mounted preferably on a set of studs allowing gases leaving the percussion system and, where applicable, the breech, to go outside the system - an elastic sealing membrane being capable of complete the protection of the percussion system.
- Loading or placing heavy tools is carried out according to the invention using a cable which passes axially through the launch tube.

- the device for pyrotechnic projection of tools according to the invention is mounted inside a frame or barrel 1 of form general cylindrical fitted with a gate 2 allowing to access the installation part of the tool.
- the launch structure mounted inside the frame 1 is consisting of a ballast mass 3 which serves as a guide element of the launch structure in the frame during the recoil of it, of a bottom or flange 4 of the chamber of trigger and launch tube 5.
- the chamber assembly combustion receiving a gas generator 9 is constituted a burst-resistant cylinder head 7, a plate 8 breakthrough exhaust ports 18 of the combustion, of a casing forming a loading envelope 10.

- the propellant powder 31 is ignited by the primer 28 and the ignition powder 27; she burns very quickly by creating a lot of gas which generates a high pressure in chamber 5a of the launch tube 5.
- This pressure propels, on the one hand at high speed downwards, the piston 41 and the tool attached to it and, on the other hand upwards, the cylinder head 7 as well as the launch tube 5 and ballast mass 3.
- the tool by example the penetrometer 43, sinks into the ground while that the whole launch tube and ballast weights 3 rises a few decimeters upwards, being held back by the effect of gravity; they fall back into position or in battery braked by the gas spring 6.
- the projection device can then be put on place over a new shooting location, if if necessary using a tool of another type, a tube of launch of another diameter and propellant charges different.

- the electromagnet can be replaced by another percussion system such a pneumatic cylinder, a spring-cylinder assembly hydraulic, a spring bandaged manually or by a electric motor. If the ignition of the gas generator is produced by laser or channel electric, the electromagnet is replaced by a source laser or correspondingly by an electric trigger likely to be connected to an electrical source such as a battery.
- a cover plate 15 bearing the striker 13 closes the breech 7 upwards, for example by simple translation in grooves 16 (see figure 3).
- the cylinder head 7 thus constitutes a subset rigid and interchangeable fixed externally and removably at one end (flange 4) of the tube launch 5.
- the vents 17 open into an annular chamber 1a which is mainly delimited between a cylindrical extension 1b of the frame 1 and the outer wall of the tube launch 5.
