Using of powdered fuel is almost impossible during all history of rocket engines. It burns so fast that the gas pressure destroys the engine’s casing. To solve this problem the fuel is pressed usually and an inhibitor is added. In my research I developed a new technology of controlling pressure inside the solid-fuel rocket. It simplifies greatly the process of making engines, allowing adjusting their parameters to get the maximum thrust safe pressure inside engine. Using this technology I created a working small engine for rocket modeling. It was tested and works well in real flights. I will continue the research of my new technology to understand its limits, increase efficiency and possibility to scale up for bigger appliances. It’s the next generation of solid-fuel rocket engines.
Aldol condensation of aldehydes is one of the most demanded reactions for the formation of a connection between two carbon atoms. Products obtained with its help are widely used in various areas of the pharmaceutical, cosmetic and petroleum industries. Aldol-croton condensation of propyonaldehyde allows to obtain products that can improve the quality of motor fuel, and valuable intermediates for organic synthesis.The scientific novelty of the results obtained is that the process has been heterogenized. A new pathway for the formation of heterogeneous catalysts on titanium (IV) oxide has been proposed. A unique method for selectively proceeding the reaction to obtain 2-methyl – 2-pentenal by using 5% AA (Norleucine) on TiO2 as a catalyst is proposed.
Electronic hardware and software system for posture correction and platypodia diagnosis among adolescence and middle school students
The accomplished scientific and technical project is aimed at preserving children’s health. School age is a period of ontogenesis, when various types of impaired posture are clearly manifested. According to statistics, 10-40% of school-age children show signs posture faults. The project solves a complex of interdisciplinary applied problems of posture correction and flatfoot diagnosis, taking into account the interdependence of posture disorders and foot deformities. The project is done at the intersection of human physiology, rehabilitation science, and electronic engineering. A hardware-software complex including a combined posture corrector for teenagers and a stop-meter detecting signs of flatfoot is developed. Several models of the device are produced and tested.
