The invention relates to an energy-saving power-assisting system for an aero-engine. The system includes a pair of engines, a pair of electric / power generation two-purpose machines and a pair of propellers, with the engines, the electric / power generation two-purpose machines and the propellers being in a one-to-one correspondence relationship, and the engines, electric / power generation two-purposemachines and propellers being connected coaxially. The engines provide total power for the system, and the electric / power generation two-purpose machines set a nominal voltage according to a take-offnominal voltage program, wherein a half of the nominal voltage is a reference voltage of an electric power-assisting state; if a voltage greater than a half of the nominal voltage is applied, an electric boost state exists; if a voltage lower than a half of the nominal voltage is applied, an electric deboost state exists; if a voltage equal to 0 is applied, a power generation state exists; and the output power of the electric / power generation two-purpose machines is not greater than 5% of the output power of the engines. The system also includes a pair of torque sensors, a pair of rotation speed measurers, an accumulator and a pair of system controllers. The torque sensors and the rotation speed measurers measure torque and rotation speeds of the engines, the electric / power generation two-purpose machines and the propellers respectively. The capacity of the accumulator is not more than electricity consumption in 30 s of the electric / power generation two-purpose machines.
Description
technical field [0001] The present application relates to the technical field of prime movers, in particular to an aero-engine booster, an aero-engine energy-saving booster, and an aero-engine energy-saving booster system. Background technique [0002] The difference between a multi-rotor helicopter and a single-blade helicopter is that the multi-rotor helicopter uses n pairs of propellers to fly, and the attitude balance of each pair of propellers needs to be controlled dynamically. The main blade of a single-blade helicopter is located on the axis of the center of gravity, which is naturally drooped to obtain balance. Pros and cons: When one propeller fails, the remaining rotors of the multirotor can continue to complete the work of navigating or landing safely, while the solo helicopter is destroyed. Obviously, the practicality of multi-rotor helicopters replacing single-blade helicopters is a technical expectation. [0003] At present, for multi-rotor helicopters drive...
