An aerial platform provided with a power-assisting system

Abstract

The invention relates to an aerial platform provided with a power-assisting system. The platform includes engines, electric / power generation two-purpose machines and propellers, which are connected coaxially. The engines provide total power for the platform, and the electric / power generation two-purpose machines set a nominal voltage according to a take-off nominal voltage program, wherein a halfof 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 platform also includes torque sensors, rotation speed measurers, an accumulator and 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. The platform reduces the probability of plane crash and improves cruising power byhundreds of times.

Description

technical field [0001] The invention relates to the technical field of helicopters, in particular to an aeroengine booster, an aeroengine booster system and an aerial platform with a 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. The pros and cons are: when one propeller fails, the remaining rotors of the multi-rotor helicopter can continue to complete the work of sailing or landing safely, while the single-rotor 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 driv...
