Jiangsu man made helicopters
Out of a hobby for airplanes, 59-year-old Chen Ruihua from Changshu, Jiangsu began designing his own nearly ten years ago, and has successively built four small manned aircraft. Among them, the second and third aircraft were successfully tested. After the video of the test flight was posted by friends on the short video platform, it aroused some attention, and many people praised him.
On March 28, Chen Ruihua told the Jimu News reporter that he was in the process of making the fourth plane and would obtain the necessary qualifications in the later stage.
Homemade helicopter test flight alerts police
In the above video, a manned helicopter took off slowly in an empty green field and rose to more than ten meters above the ground. After the helicopter took off, it circled over the field.
According to local media reports in Jiangsu, the incident occurred within the jurisdiction of Miaoquan Community in Changshu City. The police of Miaoquan Police Station found that the helicopter in the video was simple in appearance and had no protective measures. After visiting and investigating, it was found that the helicopter was made by a local old man. The police then found the old man to persuade him that the self-made plane itself is not illegal, but if you want to test the flight, you need to get the approval of the air traffic control department, and the test flight personnel must also have pilot qualifications.

Many netizens commented on the relevant reports and praised the old man: "There are experts in the folk." Some netizens pointed out that the control system of the helicopter looked a bit complicated: "The coaxial reverse propeller is very advanced." Many netizens also reminded Uncle pay attention to safety.
On March 28, Jimu News reporter contacted Chen Ruihua, the old man involved. He said that the video of the helicopter test flight was posted by a friend, and he did not expect that it would attract the police.
4 manned small planes made by themselves in ten years
Chen Ruihua, 59, is from Guli Town, Changshu City, Suzhou. Nearly ten years ago, Chen Ruihua was still engaged in hardware manufacturing. At that time, he had a strong interest in aircraft and came up with the idea of making a small aircraft.
To this end, Chen Ruihua checked a lot of information, designed the drawings by himself, selected a suitable engine, and made most of the parts by himself, and asked a manufacturer to process some of them on his behalf. He is usually busy with work, so he uses the rest time to assemble the engine and parts little by little. Chen Ruihua said that he will carefully match the parts according to the design before assembling, and there are few mistakes.
The first aircraft Chen Ruihua assembled was a gyrocopter. Since there was no suitable road for taxiing and no conditions for take-off, he did not complete the aircraft. After that, he chose to build a helicopter, found a picture of the appearance of a Japanese miniature helicopter on the Internet, and made it after drawing the design drawing. A friend drove the helicopter to practice driving, and he adjusted the aircraft according to the flaws he found. The plane weighs about 95 kilograms, making it the lightest. However, Chen Ruihua found that there was a high temperature problem in the second aircraft engine, but unfortunately he could not find a solution.
At the beginning of 2020, Chen Ruihua began to make the third helicopter, referring to the appearance of a Russian model. He bought the ATV's engine and got the parts ready as usual. More than a year later, the third aircraft "coaxial twin-rotor helicopter" was assembled. He and his friends found an open space and avoided the crowd for the test flight. The plane took off successfully again this time, and the helicopter flew many times later, and there were no problems such as high temperature.
The fourth foldable wants to drive himself
Chen Ruihua introduced that he spent about 20,000 yuan to buy the engine of the third plane, and the whole machine cost at least more than 100,000 yuan. "I didn't count how much it cost, because there are too many parts to count." Chen Ruihua said. To his delight, his family basically did not hinder his production.
Chen Ruihua is very confident about the plane he made. "How long you fly depends on your mood at the time. Sometimes you can fly for half an hour, and sometimes it will come down in a few minutes," Chen Ruihua said. "Generally, the height is about 20 meters, and occasionally it will fly higher, even a few hundred meters. It's a problem." Chen Ruihua enjoys the process of designing and manufacturing aircraft more than flying a helicopter.
Recently, Chen Ruihua is assembling the fourth aircraft and has completed the frame part. A friend would lend him a "Rotex 582" aero engine. According to his design, the power of the fourth aircraft engine is lower than that of the third aircraft, and the overall weight of the aircraft can also be lower than the 175 kg of the third aircraft. In addition, the fourth aircraft will have a folding function for easy transport and storage.
"When the assembly of the plane is completed, he will report to the air traffic control department and prepare to experience the feeling of flying into the sky." Chen Ruihua said to the Jimu news reporter.
