Description

Electric duct model convenient to install Technical Field The utility model belongs to the technical field of installation, and relates to an electric duct model convenient to install. Background The electric duct is a propeller which comprises a fan inside a nacelle with an inlet and an outlet, and is usually used as an aviation propeller, wherein the fan is used for accelerating air flow to generate thrust, and the duct plays a role of guiding and gathering the air flow in front of the fan and diffusing the air flow behind the fan to the outside. The electric duct is an aeroengine using a motor to replace a traditional duct fan, and can achieve quicker system responsiveness, lower noise pollution, more flexible transmission system arrangement and the like. The design of adopting the motor to drive the ducted fan to generate flying power can greatly improve the environmental protection, economy and reliability of the aircraft from the concepts of high efficiency, energy conservation and green safety. When the existing electric duct is used, the airflow at the position of the duct air outlet flows heterogeneous, so that a certain amount of energy loss can be caused, and the energy waste is caused in the flight process of the aircraft. Disclosure of utility model The electric duct solves the technical problems that when the existing electric duct is used, airflow at the position of an air outlet of the duct flows heterogeneous, so that a certain amount of energy loss is caused, and energy waste is caused in the flight process of an airplane.
