When a plane with a wingspan of 4.6 meters slides in the rumbling sound of the engine and flies into the blue sky, you can believe that this is a solar-powered aircraft that has been manufactured without any mechanical processing. ? A few days ago, the annual "National Research Aerospace Model Championships for Scientific Research" came to an end. In this major event organized by the State Sports General Administration, the Ministry of Science and Technology, and the Ministry of Education, which attracted more than 900 students from 46 colleges and universities across the country to compete on the field, major events that demonstrate students’ ability to work and independent scientific research in universities and colleges, Tianjin University TIM The model team successfully won the first prize in the national solar-powered aircraft design flight and the fourth national solar-powered model aircraft award.
The event is rooted in colleges and universities. It aims to promote the development of China's aerospace model science and technology practice and innovation activities and cultivate comprehensive independent innovation talents. In addition to the basic electric glider, the participating projects include model rockets, simulated search and rescue, dual-separation, aerial photography, solar-powered airplanes, vertical take-off and landing, and heavy-duty airdrops. The students are required to design their own hands, make manual productions, and carry out manual debugging. The competition subjects focus on combination with practical applications, seek technological breakthroughs and innovations, and cultivate student hands-on and independent research capabilities.
This competition is the fourth time that the TIM model team of Tianjin University has participated in the competition. The participating projects have also expanded from the previous “gliders†and “helicopter simulation search and rescue†to this year’s “solar planes†and “1kg payload airdropsâ€. Team members of the TIM model team took a six-month preparation for this competition, sacrificed the summer and rest time of the “11â€, and overcame all kinds of difficulties, from the drawing of a 5-meter-long drawing by hand to the use of a knife by a knife. Each rib was engraved and a piece of laminate was sanded until the end of the solar model.
On the day of the competition, the 4.6-meter aircraft with a wingspan of the TIM model team attracted many onlookers and college athletes. No one believes that this beautifully crafted aircraft did not use any machining, but all Handmade. In the end, the Tianjin University team won the National First Prize for Solar Aircraft Design Flight, the Fourth National Solar Load Model Aircraft, the Third Prize for Electric Remote Control Glider, and the Third Science and Technology Innovation Project in the 2012 National Aerospace Model Championships for Scientific Research. Awards.
The 9th "Scientific Research National Aerospace Model Championship" was held in Jingmen, Hubei Province
Solar Mounting System For Green House
The Installation of Mounting Unit
1. Make the concrete base according to solution drawing, locate embedded bolts and set out strings by Laser Level to ensure the centers of embedded bolts in the same elevation as accurate as possible on vertical, horizontal direction and at end face.
2. Locate the Anchor Plate on the concrete base and adjust the position according to solution drawing(remove M14 washer,M14 spring washer,and M14 nut if they are connected to embedded bolts now),and then fasten M14 washer, M14 spring washer, and M14 nut with the tightening torque of 60N.m.
3.Take out the Hexagon Bolt Kit with Post B Corrugated Gasket M12x95 and remove its nut, spring washer, one washer, and corrugated gasket. Insert the Post A, B, C in to Anchor Plate according to the Hexagon Bolt Kit with Corrugated Gasket M12x95 drawing and then fix them by two sets of Hexagon Bolt Kit with Corrugated Gasket M12*95. Post C Post A
4.Remove the bolt kits M12*90 from all the Posts and Pre-Assembled Supports and unfold the embedded Supports, fasten them on the Posts by bolt kits M12*90 according to the drawing.
Installation of Rails
1.Please check the length of Beam before place it onto the Pre-Assembled Supports, otherwise extend it with Splice forBeam first. There are 4 self-tapping screws in each side and total 8 self- tapping screws in both sides. We strongly recommend NOT extend the Beams on Preassembled Supports.
2.Before locate the Beams, mark the position of the Beam son the surface of Pre-Assembled Supports with maker pens according to solution drawing for easier installation. Place the Beams on the 55*80 Tube of Pre-Assembled Supports and fix it with C Clamp Kits. Install all the Beams in the same step. The tightening torque will be 20N.m. C Clamp Kit Side Beam(Please arrange 3-4 persons to install when the array is long.)
Installation of Solar Panels
1.Place the panels above the Beam 85, fixing it with Wide End Clamp Kit in the side and Inter Clamp Kit in the middle. Install all the panels in the same steps until complete installation of al panels. Fasten all the bolts with tightening torque of 10N.m.
2.Complete installation, and please inspect and make sure all the bolts are fastened.
