Abstract

The invention provides a deformed fairing structure of an aircraft engine, comprising a front fairing, a main fairing, a rear fairing, a connecting bridge, and an inner casing; the rear end of the main fairing is movably connected to the rear fairing; the main fairing There are 6 connecting bridges welded inside, and the main fairing is connected to the inner casing through the connecting bridge; the surface of the main fairing shell is connected to the cover plate by screws; the bottom end of the main fairing is connected by a rotating shaft and installed with a speed brake; The top and bottom ends of the front fairing can be connected by a rotating shaft and a spoiler tip can be installed; the inside of the rear fairing is sleeved with an extension frame, and the top end of the extension frame is connected to the inside of the main fairing; Rail bracket. The setting of the front fairing and the spoiler tip solves the problem that the existing fairing equipment can provide a fixed aerodynamic shape, rarely has the ability to change its own aerodynamic shape, and is not flexible enough in use.

Description

technical field [0001] The invention belongs to the technical field of supporting structures of aero-engines, and more specifically relates to a deformed fairing structure of an aero-engine. Background technique [0002] The fairing refers to the aerodynamic surface installed at the position of the propeller of the aircraft engine, that is, the outer cover of the engine, referred to as the fairing. The outside of the fairing is streamlined, which is beneficial to reduce the force of the wind on the nacelle. As the name suggests, it is used to adjust the airflow. Without it, the pipelines of the engine will be exposed to the outside, resulting in considerable resistance. In addition to this, the fairing also protects the original engine components. Because there will be a lot of airflow during flight, which will cause damage to the engine of the aircraft, and the fairing can well protect the internal components of the engine. Aesthetics are also a by-product of the fairing....
