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.From there:https://grabcad.com/challenges/asme-student-challenge-designing-for-social-impactDrone (helicopter)Scheme - tandemELECTRIC 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 kgMax. useful weight - 350 kgMax. speed - up to 200 km / hCruising speed 170 km / hMax. fuel supply in ext. capacity 220 litersPossible 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 TS100ZAhttps://www.pbs.cz/en/our-business/aerospace/aircraftginesMax. power - 180 kWNominal - 160 kWCruising (helicopter mode) - 140 kWTurns on the drive shaft 5978 RPMI also used an electric car (generator / motor) from Slovakia EMRAX 268https://emrax.com/products/emrax-268/Peak power 200 kWLong-term operation of 100 kW (with water cooling)Gorgeous 3D model EMRAX 268 presented hereEmraxSpecialized aircraft stretcher (3D model) hereAircraft Emergency StretcherThis 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.
