Sometimes reaching a remote location to provide humanitarian aid is challenging and slow. Engineers around the world have been experimenting with different ideas for addressing those challenges, and drones have shown tremendous promise and opportunity.

Drone (helicopter)
Scheme - tandem
ELECTRIC transmission: 2 generators driven by a turboshaft engine and 2 electric motors (mutually synchronized in rotation and azimuth of the rotors)
Max. take-off weight - up to 1000 kg
Max. useful weight - 350 kg
Max. speed - up to 200 km / h
Cruising speed 170 km / h
Max. fuel supply in ext. capacity 220 liters
Possible missions
• THE RESCUER (tow) is the most humane mission
• transport - the load can be placed inside or on the external sling
• agricultural - sprayer, tank capacity with chemicals up to 300 liters
• fire - liquid, foam, tank capacity up to 300 liters
• patrol - additional fuel tank 400 liters
•…
The choice of the longitudinal scheme of the helicopter due to a number of indisputable advantages over other schemes. However, there are significant problems for implementation.
The project used Czech turboshaft engine TS100ZA

Max. power - 180 kW
Nominal - 160 kW
Cruising (helicopter mode) - 140 kW
Turns on the drive shaft 5978 RPM
I also used an electric car (generator / motor) from Slovakia EMRAX 268

Peak power 200 kW
Long-term operation of 100 kW (with water cooling)

This is the maximum that can be squeezed out of the hybrid concept on modern components, without going over the edge of reality.
This is only a conceptual symbolic scheme. This does not pretend to any detailed construction and is not confirmed by calculations.
