Description

Technical field [0001] The present invention relates to the field of electric aviation, and more particularly to an auxiliary propulsion device and an electric aircraft. Background technique [0002] With the development of new energy technology, more and more countries and enterprises began to lay out in the field of electric aviation. Specifically, the biggest technical challenge facing various types of electric aircraft is that the key performance indicators of electric power promotion systems are low, technology is immature, and the weight is too large. It can only meet the minimum use requirements of electric aircraft, where electric aircraft battery energy density is insufficient. The electric power promotion system is too large. The biggest problem of electric aircraft design, causing the flight voyage of the electric aircraft to meet the demand. The prior art has a technical solution to assist in driving an electric aircraft in the prior art, but the auxiliary propulsion ...

Problems solved by technology

Specifically, the biggest technical challenge facing the development of various types of electric aircraft is that the key performance indicators of the electric propulsion system are low, the technology is immature, and the weight is too large, which can only meet the minimum requirements for the use of electric aircraft. Among them, the energy density of electric aircraft batteries is insufficient. , the excessive weight of the electric propulsion system is the biggest problem in the design of electric aircraft, resulting in the flight range of electric aircraft cannot meet the demand

In the prior art, there are technical solutions for using the auxiliary propulsion device to assist in driving the electric aircraft, but the insufficient thrust of the auxiliary propulsion device and the limited battery capacity are also problems that need to be solved
