Problems solved by technology

However, the moment of inertia of the propeller of the stratospheric airship is large. When the driving motor drives the propeller to accelerate, a large amount of electrical energy needs to be converted into mechanical energy. The inverter circuit in the battery converts it into electrical energy and stores it in the energy storage battery, but this will increase the charging and discharging frequency of the battery and affect the service life of the battery

Abstract

The invention discloses an energy storage type stratosphere airship motor and a control system, and relates to the stratosphere airship motor technology field. The energy storage type stratosphere airship motor is mainly constituted by a power unit, a transmission unit, and an energy storage unit. The power unit is formed by a stator and a rotor, and is used to provide driving / braking torque. Thetransmission unit is used to connect the rotor of the power unit and the energy storage unit by a clutch and a gear box with a variable transmission ratio. The energy storage unit is used to store themechanical energy of the load during the deceleration of the energy storage type stratosphere airship motor, and is used to convert the stored energy into the mechanical energy of the load, when theload is required to be accelerated, and therefore the weight of the battery is reduced. According to the invention, the energy utilization rate can be improved, and the requirement of the stratosphereairship power system on the energy system can be reduced, the loading capability of the stratosphere airship can be improved, and the acceleration and deceleration capability of the stratosphere airship motor can be improved.

Description

technical field [0001] The invention relates to the technical field of stratospheric airship motors, in particular to an energy storage type stratospheric airship motor and a control system. Background technique [0002] The stratospheric airship is a long-endurance aircraft. Because it generates lift by floating in the air, the thrust requirement is much lower than that of an aircraft flying at the same altitude, and the corresponding flight altitude has thin oxygen, so it cannot use the aero-engine when the air intake is insufficient. , so stratospheric airships generally adopt electric propulsion. The height of the stratosphere above the ground is greater than 10km, and the velocity and direction of the airflow change with time. At the same time, due to the large cross-section of the airship, the airflow will have a greater impact on the attitude and heading of the airship. Therefore, in order to achieve long-term fixed-point residence and fixed-direction flight, the str...
