The invention relates to a hybrid drive system (4) of a helicopter comprising a controller (5, 7, 11) and a driveshaft (3), said helicopter having a main rotor (1) which is connected to a gearbox and which can stabilize the flight attitude predefined by the pilot. The hybrid drive system comprises a pilot controller (5) and both a burner (VM) (6) and an electric motor (EM) (10) both in direct engagement with the driveshaft (3). The burner (6) is connected to a burner controller (7) and the electric motor (10) is connected to an electric motor controller (11). According to the invention, a torque sensor (17) and a tachometer (18) are each positioned on the driveshaft (3), where both the burner controller (7) and the electric motor controller (11) can each receive values of a current rotational speed (DZ) and a current torque (DM) during operation. Predefined values of the rotational speed (DZ0) and the torque (DM0) at which the burner (6) is at which the optimum efficiency thereof can be increased with said values are stored and can be retrieved by the electric motor controller (11), and the rotational speed (DZ0) can also be retrieved by the burner controller (7). A first command is stored in the electric motor controller (11) to always apply a driving or braking force from the electric motor (10) to the driveshaft (3), the force causing the burner (6) to automatically generate the torque (DM0) at the driveshaft (3) when it has reached or maintained an optimal rotational speed (DZ0) at the driveshaft (3), at the torque, the burner achieves the optimal motor power. The invention also relates to a corresponding method.

    本发明涉及一种直升机的包括控制器(5,7,11)和传动轴(3)的混合传动系统(4),所述直升机具有主旋翼(1),所述主旋翼连接到变速箱并且可使由飞行员预定义的飞行姿态保持稳定。所述混合传动系统包括飞行员控制器(5)以及均与所述传动轴(3)直接接合的燃烧机(VM)(6)和电动马达(EM)(10)两者。所述燃烧机(6)连接到燃烧机控制器(7),并且所述电动马达(10)连接到电动马达控制器(11)。根据本发明,扭矩传感器(17)和转速计(18)各自定位在所述传动轴(3)上,其中所述燃烧机控制器(7)和所述电动马达控制器(11)两者可在操作期间各自接收当前转速(DZ)和当前扭矩(DM)的值。所述燃烧机(6)可利用所述值提高其最佳效率时所处的转速(DZ0)和扭矩(DM0)的预定义值被存储并且可由所述电动马达控制器(11)检索,并且所述转速(DZ0)还可由所述燃烧机控制器(7)检索。第一指令存储在所述电动马达控制器(11)中以始终将来自所述电动马达(10)的驱动或制动力施加到所述传动轴(3),所述力使得所述燃烧机(6)在其已达到所述传动轴(3)处的最佳转速(DZ0)或维持所述最佳转速(DZ0)时在所述传动轴(3)处自动产生所述扭矩(DM0),在所述扭矩下,所述燃烧机实现所述最佳马达功率。本发明还涉及一种对应方法。
