My long-term plan is over. 11 months have passed, I hope, not in vain.
So...Model of plane An-24RV in the livery of UTair. For the original, I decided to take the RA-46481. There were a lot of photos on it. The construction took a long time, 10 months. Engineering thought worked at full speed. As a result, we got what we got ))). The idea of the diorama is as follows: the plane is preparing for departure, the engines are started from the airfield distribution column ASK-2. If this is something fancy, please do not scold ).
The main point in the glider was to cut out the flaps and install them in the take-off position. Quite a time-consuming process, I had to break my head over the mounting. As a result, the flaps are mounted to the root of the wing with pins. It is very convenient to adjust the desired angle.
Improvements to plastic are already familiar - riveting, sensors, hydraulic wiring on racks, boring air intakes, static drainers and other small things.
Raisin models in electrification. Motors and flashing elements are controlled by a circuit on the Arduino Nano platform. It is very convenient to program different modes. Anyone who wants to contact this, I recommend it. The scheme of the engines is as follows: after feeding the power in a couple of seconds, the left engine begins to spin.ideally, the rotation should be minuscule, but DC electric motors do not allow to achieve this effect. Therefore, the propellers start at the lowest possible speed that these motors were capable of. I picked it up for a long time. So, the left engine spins 15 seconds to its maximum speed. Then the right one begins to spin. In the same way, it gradually gains momentum for 15 seconds. Then 1.5 minutes work both at the "maximum" and begin to gradually reduce the speed for 10 seconds. to a complete stop. After that, the model stands with flashing and burning BANS, the engines do not rotate. Nightlight )).
Electricity from the network adapter for a cell phone is connected to the end of the platform through a connector. A pad with pins is fixed in the platform, on which the ASK-2 column is mounted. The pad is connected to the power connector at the end of the pad. Three wires go to the plane - two power supplies ( / - ) and the third is returned from the Arduino Board to control the beacon on the column. The Board itself and the engine power module are hidden in the fuselage.
The engines were purchased in one of the city's stores. Very successful in size, as if created for placement in the engine nacelles of this model. The power supply voltage is 3V. As I mentioned above, the minimum speed of rotation did not allow you to create the effect of unwinding "from scratch", so the video has the feeling that they immediately rotate to the maximum. But the effect of further increase in turnover is quite turned out.
The beacons on the plane and the column were programmed to give the impression of a" rotating " beacon, not a strobe. At least on nighttime videos of real planes, this is what it looks like. The upper and lower flashing interval is 1.5 seconds. in antiphase. The beacon control is displayed separately on the column. There is a flashing interval of about 0.4 seconds.
