[ Adapted Englishing ]



In November 1998 in the local stadium, in the presence of hundreds of people including representatives of media from the all country, together with his collaborators,  Przemyslaw Lagiewka demonstrated the prototype of an unusual bumper. This showed what, was so unusual that continually acknowledged as impossible.

A small Fiat 126p, going 45 km per hour, was driven into a concrete wall. The bumper was not damaged. The driver wore no seatbelts. The inertial reaction, which should have thrown him onto the hood, did not ocur. The stopping distance was only 16 centimetres. Impossible? Yet hundreds of people in, and  the stadium, and millions more on television. The use in all vehicles of the absorber of the energy, "Ecollision", can radically improve automobile safety.

Lagiewka says, "The technical idea behind my buffer can be used in very many practical solutions. Another invention which I showed experimentally, is the brake. Connected to the axis on a Mercedes, the car stopped in one-quarter of the distance usually required".

I had a short conversation with the manager of the Chair of the Mechanics and Energy-Devices AGH in Cracow, with the professor with Stanislaus Gumu??.:

- What you feels about the Lagiewka buffer ?

- This is a very original solution transforming the rectilinear motion into rotatory, thanks to which it succeeded to limit radically results of the collision of two bodies. This experiment recommends however to us, to research workers, many practical and theoretical problems.

- This means that one cannot give the binding scientific opinion?

- Unfortunately, not yet. We have from several months the small model of the vehicle Lagiewki with installed absorber of the energy, but are problems with an execution of measurement of physical parameters of this event. We want to make this with several methods. The thing is that the event lasts several milliseconds, and devices which we have at our disposal, are not disposed on such small times. Filming of the event little gives, because the alloy {stop}-the cage lasts too long [?]. Diodes, what we assemble on the model, to measure accelerations, do not light with such frequency, to catch sensitively the moment of the collision. We seek also suitable sensors of the power.

- Whether solution Lagiewki surrenders unsophisticatedly to explain aground well-known laws of physics?

- Some elements of this occurrence can not be situated in hitherto existing well-known interpretations of the laws of physics. As far as more easily one can to himself explain the lack of the damage of the car at the collision shown in the stadium in Kovars, insomuch more with difficulty interpret the fact that the driver, not having buttoned belts, did not fly through the windowpane. Doubtless this matter demands serious research. Lagiewki's inventions can find wide use in the future.

Lagiewski offers examples of uses for the invention. Thanks properly to constructed absorbers of the energy large ships can stop, not in 2-3 kilometres, as now, but in 100-200 metres. One can also build rescue-landings for people jumping during fires from high buildings. In Kovars, at the local firestation, on a 6-metre tower, tests were made by jumping onto the buffer...

All mechanics is based on occurrences happening in collisions only two bodies and from such experiments are derived mathematical calculations. One did not trace, what happens, when three bodies simultaneously crash. Lagiewska tested 3-boy collisions for 20 years. The results of his research and experiments are shocking. And so at collisions of three bodies one can control the situation, so that the energy two crashing masses of greater bodies almost en bloc swim to the third smaller mass. I had personally a possibility to observe an experiment erected in the local House of the Culture. The arrangement of three situated vehicles on tracks provides a completely surprising occurrence. The small vehicle, striking simultaneously into 3 the bodies, the most of the energy gave back this to two standing from one side to movement. Into the third place of the shock, lying on the line of the movement of the vehicle, went least the energy. The kinetic energy of the vehicle chose another way than standing straight on the object. Basing on such among other things experiments, Lagiewka builds on the new mechanics. She throws rejects many hitherto existing notions and uses new mathematical levellings. Polish scientific-technical certers are examining Lagiewki's inventions.

Abstract --- The invention relates to a device for transforming kinetic energy, comprising a first body (2), which may be displaced from a starting position to an end position as a result of an external force (F) and at least one second body (7) mounted such as to rotate, coupled to the first body (2), whereby a longitudinal displacement of the first body (2) drives the second body (7) in rotation, such that the first body is braked.
