Unmanned aircraft of 5 generations of Polytechnic students

Since the Solar UAV was still on paper until the wingspan flew in the sky, the boys of the Department of Aeronautics and Aerospace Engineering (Hanoi University of Technology) course 52 to 56 joined the preliminary design. , model making, finishing, flight testing .

Unmanned aerial vehicles using solar batteries (Solar UAV) by teachers and students of Aeronautical and Aerospace Engineering, Institute of Motive Mechanics belonging to product groups won the first prize, attracting viewers at the Bright Festival creating science and technology for young people in 2016. Aircraft with wingspan of 2.5m; 1.5m long; load capacity of 1.5 kg with an average travel speed of 15m / s and a 300m flight ceiling applied in surveying, monitoring forest planting, serving rescue and rescue.

The aircraft operated by the student group K56, Bui Van Thanh, Tran Trung Duc, Ngo Xuan Chinh, Dao Van Long and Nguyen Van Dinh (K55 alumni) were conducted under the guidance of two faculty members, Dr. Dinh Tan Hung and Dr. Vu Dinh Quy. Team leader Bui Van Thanh said that the implementation of this Solar UAV research started in July 2015 at the Space and Underwater Technology Research Institute of Hanoi University of Technology.

Previously in 2012, Dr. Hung proposed to research the manufacture of unmanned aircraft using solar energy. This is a device that can be used in military and civilian applications. If unmanned aerial vehicles (UAVs) have fossil fuel engines, the flight time is good but difficult to operate when temperature, pressure changes, loud noises and may cause environmental pollution. UAV with electric motor has short flight time, limited storage battery. Therefore, Solar UAV is prioritized for research and development.

To get the product "made in Polytechnic" , students of Aviation Engineering and Aerospace courses from K52 to K55 participated in turn. They study, design preliminary, fabricate models, solve problems gradually from theory to practice, from design to manufacturing. To K56 student group, Solar UAV products have just been completed. Each team member is responsible for one stage. Thanh and Germany study energy coordination systems; Long designed and improved the product according to new requirements, Dinh worked on the overall fabrication and fabrication of the emergency rescue system by parachute.

At the end of 2015, Solar UAV started flying static tests in many environments. In January 2016, the outdoor flight test equipment was up to 24 times, the total test flight time was over 8 hours."At the beginning of April, the device flew for 35 minutes for the first time in light and windy weather at 15pm. We were happy , " recalled member Ngo Xuan Chinh, saying the device looked slim but thanks to The wingspan is wide so the ability to glide well allows you to adapt to the winds and consume less energy.

When the sun is hot, the solar energy collects through 36 panels, making the device work stably. The extra power is charged to the lipo battery stored in the fuselage.This capability allows Solar UAV to survey, monitor in large areas, require range as far as forest, coast . Solar online monitoring system and storage battery allows direct monitoring Continued and continuous Solar UAV process in operation. In case of emergency, automatic parachute rescue system will ensure safety for flying equipment.

Polytechnic teachers said that it was difficult for them. Luckily, an agro-forestry enterprise invests in the whole group. When discussing the development strategy of this enterprise, Mr. Hung proposed that there should be equipment to regularly monitor the area of ​​planting trees, planting forests to limit the felling and they agreed . step by step and businesses also invest step by step.

Most recently, on June 1, 2014 in the northeastern mountainous area of ​​the invested enterprises, when it was sunny and less cloudy, Solar UAV flew to test on the trajectory of point trajectory, serving the construction of regional 3D terrain. nearly 50 hectares wide. The aircraft operates about 3 rounds in orbit zich zac continuously, the total distance of about 50km in more than an hour. Having this result, the group intends to continue experimenting with higher requirements to improve the technology, meet the reliability and soon put the product into application.

According to Dr. Dinh Tan Hung, if the application of unmanned aircraft using solar energy to rescue and rescue in poor weather such as rain, storm . is not feasible. The team plans to improve and develop products in a way that can fly higher than the cloud layer to reduce the impact of weather, stabilizing the light intensity for solar energy. " Certainly we will improve equipment in the direction of having a large wing span, high flying ceiling to perform better tasks" , Mr. Hung said.
