SPECIAL DEVELOPMENTS. PNEUMATIC LAUNCHERS FOR THROWING BODIES. TEST STANDS.
For 20 years, RPE “ISTA” creates pneumatic launchers (PL) for the dispersal of a variety of propellant bodies (PB) according to the technical tasks of the Customers. In recent years, a number of R & D projects have been carried out, the results of which led to the creation of unique stands for testing the dynamic (impact strength) of various objects.
Installations for transferring PB to a given point, for example, probes or sensors.
Installations for starting PB at a given speed.
Installations for creating a given load on the test sample for a given finite time.
The range of parameters that were implemented in the previously created PLI is characterized by the following values, (see table).
The advantages of PL produced by RPE “ISTA” in comparison with analogues (mainly powder LI) are as follows:
- milder requirements for industrial safety in the absence of gunpowder;
- high stability and repeatability of all critical parameters;
- high performance and low cost of the experiment (see clause 4 of the table);
- high load uniformity during the entire time of PB acceleration in the barrel.
|Weight of PB, kg||0,001||60,0|
|Barrel diameter, mm||5,0||250|
|Diameters of flow sections of high-speed valves, mm||12||100|
|Barrel length, m||0,01||6,0|
|PB speed at the exit from the barrel, m / s||10,0||550|
|Acceleration, m / s2||100,0||70000|
|Time of PB acceleration in the barrel (PB time under load), ms||100,0|
