The exhibition of scientific and technical creativity was held on April 14 as part of the 76th International Student Scientific Conference of the St. Petersburg State University of Aerospace Instrumentation (SUAI).
As noted in the press service of the SUAI, it is intensively developing towards a research university, including thanks to the Priority 2030 program. A wide laboratory base, close ties with leading industry institutes, institutes of the Russian Academy of Sciences, the largest enterprises in the industry, the work of the strongest scientists and the talent of young specialists give the educational institution the opportunity to work effectively on solving the problems of modern science and technology. This is confirmed by the results of scientific competitions, won grants, awards and prizes for scientists and university students, as well as the growing authority of the SUAI as a leading educational and scientific center.
The annual exhibition of scientific and technical creativity of students and young scientists provides an opportunity to present new projects developed at the university. Yulia Antokhina, Rector of the SUAI, and Vladislav Shishlakov, Vice-Rector for Educational Technologies and Innovation Activities of the University, got acquainted with the developments. Director of the Institute of Radio Engineering and Infocommunication Technologies of the SUAI Alexander Bestugin noted that most of the developments are in demand and have applied applications.
Thus, a fire detector was presented at the exhibition, which recognizes the first signs of combustion – convective flow and smoke. “The laser heat flow detection system that we have developed can be used in explosive industries. In addition, our fire detector is linear and designed for long ranges – about 100 m – to control extended premises, ”said Yana Ryvkina, a student of group 2935 of the SUAI.
Another student project is for laser cleaning of architectural objects. At a recent international exhibition of innovations in Moscow, the installation aroused great interest. “It is able to work at any distance and with surfaces of any complex shape. With the help of the “Bessel beam”, which retains power at any distance, it becomes possible to scan the relief and delicately clean various objects. Compared to sandblasting systems that clean roughly, damaging the surface, here with the help of a fiber optic laser we only affect the damaged layer. The dirt just evaporates. The installation can be used as a portable device: several lithium batteries, a more powerful laser – and such a machine can travel all over St. Petersburg or Moscow to clean monuments, objects, structures. Even a worker, carrying a backpack with such a device, can independently clean any structures made of metal, gypsum, granite, ”explained Mikhail Trushov, a student of the 2015 group.
Students of the military training center at the SUAI Nikita Kazantsev and Danila Anokhin presented the OWL 01 unmanned aerial vehicle based on the Delta aerodynamic configuration. Its payload reaches 800 grams. The body of the center section of the drone is made by molding from composite materials. After completion of testing and improvements, students plan to assemble the design on a domestic flight controller. The development was carried out within a year, the manufacture and study of experimental samples – within a month and a half. With the help of the OWL 01 UAV, it becomes possible to monitor large areas of terrain that are inaccessible to humans, or, for example, to transfer medicines to hard-to-reach areas. One of the advantages of the wing is its low cost compared to the market.
“We present a unique platform in the form of a flying wing. The aerodynamic shape was completely developed by us, the student group of the military training center at the SUAI on the basis of the Engineering Garage. The exhibit is small-sized, has an increased flight time of up to one and a half hours in the air. The uniqueness lies in the fact that, in addition to the new aerodynamics, we use other materials: the old version is made of foam, the new one is made of polypropylene foam, EPP, impact-resistant material. These are experimental samples, but we will get the final result soon. This is an aerodynamic, small-sized, impact-resistant, affordable exhibit,” explained Nikita Kazantsev, a student at the military training center at the GUAP.
Sergey Yan, senior lecturer at the Institute of Radio Engineering and Infocommunication Technologies of the SUAI, spoke about the development of a three-axis CNC machine using his own software for small-scale production of printed circuit boards. Using a laser through a photoresistor, a pattern is applied to printed circuit boards. After that, the laser replaces the engraving of the Dremel hand-held electric and pneumatic tools, holes are cut and a full cycle of printed circuit board production is obtained at the university site. The uniqueness of the exhibit lies in the transfer of analog equipment to digital. Thanks to the development, students of the Department of Design and Technologies of Electronic and Laser Means of the SUAI will be able to perform laboratory and final qualified work.
Some of the exhibits were also presented at the international exhibition of innovations and the competition of scientific developments HI-TECH, which was held at the Expoforum site.
