Standalone Glider Tow – continue (Unbridled fantasy :)

grabcad

I took the Nimbus-4 glider to demonstrate my system in GrabCAD by Antanas Sulskis, and I want to express my gratitude for such a design. The use of the Nimbus-4 airframe makes this system look more impressive. Nimbus 4 glider flies smoothly, just like doves always return to their nest - "GOLOUB" (Dove in Ukrainian) should return to the starting point. The main difference from previous versions is using a hard wing for the module to fly to the launch site. The rigid wing of the towing vehicle acts as a glider flap when in hitch configuration, so the glider's own flaps are not used during takeoff. Docking the tow to the glider happens without any additional separate elements. The towing design is versatile and easily adapts to different gliders of similar type (e.g., Nida or Nimbus). Adaptation occurs by turning the wing parallel to the trailing edge of the glider wing. After disconnecting the towing vehicle, its wing automatically sets itself strictly perpendicular to flight. The towing vehicle has a "duck" aerodynamic design and doesn't lose balance (the lifting force is created by the wing and the horizontal tail). Fundamentally: the center of lift and the center of gravity of the glider plus tow system ensure the stability and controllability of the system only by the glider rudders. An increase in the lifting force of the system allows us to increase the towing mass up to 50 kg, which can be additional batteries - energy consumption - time of a motor flight. The EMRAX 188 electric motor weighs 6.8 kg and produces peak power of 70 kW with continuous power of 28 kW at 7000 RPM. The 7000 RPM E-BAMO-D3 controller weighs 6.5 kg, battery element is 3.6 V 1500 mAh 8C (12 A), dimensions are 76x40x6.5 mm and weight is 35 g. There are 600 elements - 3.2 kWh - 21 kg in total, estimated runtime is 10-12 minutes.
