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

The auxiliary propulsion device comprises a central body wing, a nacelle and a power mechanism, the nacelle is fixed on the central body wing, and the nacelle and the central body wing are connected A duct is formed between them, the power mechanism includes a battery and a first propulsion piece, the battery is installed in the accommodation space of the central body wing, the first propulsion piece is electrically connected with the battery, and the first propulsion piece is installed in the duct; the electric aircraft includes The aircraft body, the second propulsion member and the above-mentioned auxiliary propulsion device, the second propulsion member is installed on the aircraft body, and the auxiliary propulsion device is docked on the aircraft body. The auxiliary propulsion device is arranged in a flying wing layout, which improves the lift-to-drag ratio, has a compact structure, and increases the battery volume in the accommodating space, and the installation of the nacelle increases the installation size of the first propulsion member; furthermore, the auxiliary propulsion device assists the second propulsion device. The propeller is used to drive the aircraft body to fly, which improves the flight range of the electric aircraft.
Description
technical field [0001] The invention relates to the technical field of electric aviation, in particular to an auxiliary propulsion device and an electric aircraft. Background technique [0002] With the development of new energy technologies, more and more countries and enterprises have begun to deploy the electric aviation field. Specifically, the biggest technical challenges faced by the development of various electric aircraft are the low key performance indicators, immature technology, and excessive weight of the electric propulsion system, which can only meet the minimum use requirements of electric aircraft. Among them, the battery energy density of electric aircraft is insufficient. , the excessive weight of the electric propulsion system is the biggest problem in the design of electric aircraft, which leads to the fact that the flight range of the electric aircraft cannot meet the demand. In the prior art, there is a technical solution of using an auxiliary propulsi...
