One of the main technical characteristics formodern electric multicopter is the time of autonomous flight on a single battery charge. On average, such devices can fly no more than 30 minutes. However, for hybrid devices using a drive system that runs on gasoline and electricity, the autonomous flight time can increase several times. One of these quadrocopters, created by the Quaternium company in Spain, recently broke its own record and spent 10 hours 14 minutes in the air.
First model developed by Quaterniumunder the brand name HYBRiX 2.0, in December 2017 flew on a hybrid engine for four hours and forty minutes. This time became a new world record for autonomous quadcopters. Further improvement of the model allowed the company to release the HYBRiX 2.1 model, which in February 2020 set the next world record for autonomous flight time, which was already 8 hours 10 minutes.
Further improvement of HYBRiX parameters 2.0 was performed by changing the parameters of the drone's fuel system. The developers increased the volume of the fuel tank to 16 liters and installed a fuel injection system for the two-stroke quadcopter engine. The injection system is made by the Spanish company Löweheiser, it is quite compact and does not affect the total weight of the device.
As standard, the HYBRiX 2.1 has a mass of 13 kg, can carry up to 10 kg of payload, has a cruising speed of 50 km / h and is capable of a maximum speed of 80 km / h.
