Today, many elements of rocket constructions are made of carbon fiber, but control of such products is complex and costly. Thus, the students at Space Engineering School decided to create a "Dilatometer", an experimental measuring device designed to find the coefficient of thermal expansion of samples of carbon-fiber pipes of 100 to 1500 mm in length in the range of 18 ÷ 30 ° C.

The project was launched on May 10, and on August 10 the team plans to complete it. Students undergo intensive training with mentors and learn how to create laboratory measuring devices.

The dilatometer is one of the instruments created by students for students, as it is planned to use the device in future programs of the School, such as visual optical control, digital signal processing for non-destructive testing and others.

The project team consists of three students who work under the supervision of Alexander Tikhonovich Kudrevatykh, Head of the Laboratory of Nondestructive Testing of the Radioelectronic Automation Department at DNU: 

  • Kateryna Dercal, 4th year student of the Radioelectronic Automation Department; 
  • Ksenia Novik, 1st year student of the Radioelectronic Automation Department; 
  • Stanislav Kaplun, PhD candidate at the Radioelectronic Automation Department.

At this stage, participants have already conducted a comprehensive analysis of modern domestic and foreign instruments for measuring the coefficient of thermal expansion and are actively developing a scheme of the dilatometer. 

The team has also made the purchase of materials and began testing the equipment, among which:

  • board Arduino Mega 2560;
  • Mega Sensor Shield V2.0 for Arduino Mega 2560;
  • atmospheric pressure sensor BMP180;
  • digital humidity and temperature sensor GY21;
  • temperature sensors DS18B20;
  • module of the non-contact thermometer MLX90614;
  • module power key MOSFET AD4184.

Onwards, students will work on the electric circuit of the heater, the 3-D model of the dilatometer, develop methods for measuring the coefficient, create a software, assemble and debug the device, perform CTE measurements of two samples of carbon-fiber pipes.

The results of the project will be presented in 2 months. Follow our updates to be the first who will see the work of the device!
