Abstract

The invention provides a vector adjusting spray pipe and a self-adaptive variable cycle engine, and the vector adjusting spray pipe comprises a stress application cylinder (1), a nozzle (2) and a nozzle (3), the outer casing (2) is arranged on the radial outer side of the stress application cylinder body (1), and a part of an outer duct (100) is limited between the stress application cylinder body (1) and the outer casing (2); the force bearing ring (3) is provided with a hole (31), the hole (31) can enable airflow to flow to a tail nozzle of the vector adjusting spray pipe in the outer duct (100), and the force applying cylinder (1) and the outer casing (2) are connected through the force bearing ring (3); and the vector adjusting mechanism is connected to the outer casing (2), and the vector adjusting mechanism can enable the vector adjusting spray pipe to contract, expand or deflect in a vector mode.

Description

technical field [0001] The application belongs to the field of aero-engines, and in particular relates to a vector regulating nozzle and an adaptive variable cycle engine. Background technique [0002] The variable-cycle propulsion aero-engine has many advantages over the traditional fixed-cycle aero-engine. With the continuous improvement of the design level of aero-engines, engine cycles and structures that meet the requirements of variable cycles have been continuously proposed and evolved, and variable-cycle propulsion aero-engines are gradually used for main combat aircraft power. [0003] Compared with the variable cycle engine, the self-adaptive variable cycle engine adds an external bypass (also known as the third bypass) on the basis of the double external variable cycle engine. The added external bypass can further improve the change of the engine bypass ratio. range, optimize the overall performance of the engine within the envelope, reduce the overflow resistanc...
