A propulsion system for a multirotor aircraft, the propulsion system comprising: at least one power generation module configured to provide a first source of electrical power to one or more propulsion assemblies of the multirotor aircraft; a control system which is configured to determine the required electrical power demand of the propulsion assembly and calculate a predicted electrical power demand for a following period of time; wherein the control system is configured to alter the electrical power produced by the power generation module such as to produce a power envelope which comprises the electrical power produced by the power generation module corresponding to the predicted electrical power demand; wherein the control system is configured to determine if the power envelope meets the required electrical power demand; and wherein when the power envelope is less than the required electrical power demand the control system is configured to selectively connect a second source of electrical power for supplying power to the propulsion assembly such as to compensate for the difference between the power envelope and the required electrical power demand.
