Warsaw. Students of the Warsaw University of Technology invented a device to rescue drowning people

An important advantage of the device is the lack of contact with the drowning person. Students from the Faculty of Automotive and Construction Machinery at the Warsaw University of Technology have constructed a project of a pneumatic rescue dart and a throwing system that will allow rescue in water up to a distance of 60 meters.

As the university informed on its website, “the system consists of two pneumatic cushions with a pumping mechanism that is activated upon contact with water.” The pillows are enclosed in a capsule, launched towards a drowning person and having a range of up to 60 meters. The use of the device does not require direct contact with the injured person.

“A person undertaking rescue operations using our device does not need to have special qualifications and rescue skills” – emphasized Michał Niedzielczyk, who is the author of the idea together with Michał Karelus.

They consulted lifeguards

Students analyzed the currently existing solutions, applicable standards and legal acts. They checked the requirements for displacement, components used and flight parameters of the rescue capsule. They also consulted with lifeguards working in various reservoirs.

“Engineers developed the necessary models (geometric and mathematical), performed calculations (from strength to aerodynamic), designed, and then made and tested a prototype” – the university said.

“The prototype of the rescue capsule is the size of a 1.5-liter bottle of water, while the inflatable cushions are meter-long cylinders ensuring the buoyancy of modern pneumatic vests” – explained Michał Karelus, quoted by PW.

Made using 3D printing

The prototype was made using 3D printing using the FDM method. The method, the university said, involves creating objects by melting and layering a plastic material onto a base. This process, in turn, involves heating and extruding the material through a nozzle that travels along a predetermined path, creating layers that gradually build up the final 3D model.

In the next stages, the originators would like to equip rescue groups with the device, because their experience can help in further development of the project.

The idea arose as part of an engineering thesis supervised by dr hab. Eng. Lech Knap, prof. university. The thesis was awarded in the 26th competition for the best diploma thesis defended at the Faculty of Automotive and Construction Machinery at the Warsaw University of Technology (in the category of engineering works)
