Abstract

The invention relates to a duct power device and an aircraft. The duct power device comprises a driving device, a duct and rotor wings, wherein the duct and the rotor wings are arranged coaxially; the rotor wings comprise a first rotor wing and a second rotor wing which are coaxially arranged and can rotate around a coaxial line, the second rotor wing rotates relative to the first rotor wing around the coaxial line through a separating mechanism. When output power needs to be promoted, propeller blades on the second rotor wing are separated from propeller blades on the first rotor wing, and the number of the propeller blades in the duct is doubled; with the increase of the number of the propeller blades, large power can be obtained in a short time, so that the purposes of shorting corresponding time and quickly increasing the speed of the device are achieved, and the power limit of the duct power device is also effectively promoted. In addition, the service life of the driving device is indirectly prolonged. The aircraft disclosed by the invention comprises the duct power device, wherein the duct power device is arranged on the aircraft frame of the aircraft.

Description

technical field

[0001] The invention relates to the field of aircraft, in particular to a power device with a duct and an aircraft using the duct power device. Background technique

[0002] The ducted power unit equipped on the aircraft generally includes ducts, rotors and motors coaxially arranged in the ducts, and the motors can also be arranged on the periphery of the ducts and drive the rotors to rotate through the drive shaft device to achieve normal work in the ducts.

[0003] In the prior art, the ducted power device usually achieves the purpose of increasing the rotation speed of the rotor and thus the flight speed by increasing the power of the motor. For example, the Chinese patent application whose publication number is CN 104401480 A discloses a ducted tilting aircraft. It is recorded in this patent application that the aircraft includes a fuselage, and a duct is provided on the fuselage, and a ducted propeller is installed in the duct. This solution increases ...

Embodiment Construction

[0045] Example of Ducted Power Plant

[0046] Such as figure 1 with Figure 12 As shown, the present invention includes a duct 2, a driving device 1, a first rotor 3, a second rotor 4, a top cover 22, a second rotating member 8 and a first rotating member 9 connected to a threaded bush 7 through a bearing. In the present invention, the driving device 1 is a motor 1 . Such as figure 2 As shown, the duct 2, the first rotor 3 and the second rotor 4 are coaxially arranged. The second rotor 4 can rotate relative to the first rotor 3 around the co-axis through a separation mechanism. Wherein the first rotor 3 and the second rotor 4 belong to the rotor of the whole power plant. Such as Figure 9 As shown, a connecting ring 24 is installed on the bottom of the second rotor 4, and the connecting ring 24 is used to prevent the rotor from vibrating in the axial direction, so as to prevent the two rotors from colliding with each other and being damaged due to vibration. Motor 1 is...
