Abstract

The invention relates to a multi-adjoint vector thrust engine design method, and belongs to the technical field of engines. According to the invention, by carrying out turbine engine energy redistribution technology research, high-pressure airflow of a turbine engine compression system and a high-pressure kerosene fuel part of an oil supply system are led out, and technologies such as small-space combustion and thrust conversion are combined, so that a plurality of small kerosene-air jet sub-motors are formed. The main engine and the multiple accompanying engines distributed on the aircraft form multiple direct force control points, vector thrust in different directions is generated, and therefore the vector propulsion mode of the main engine power and the accompanying engines is formed.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a design method of a multi-accompanying vector thrust engine. Background technique [0002] In modern warfare, with the improvement of tactical indicators such as strong maneuverability and the rapid development of various air defense equipment, the transient tactical situation puts forward higher and higher requirements for the maneuverability of aircraft. At present, there is no unified criterion for judging next-generation fighters in the world, but experts in the United States and Russia believe that the basic characteristics of next-generation attack / defense aircraft include high-speed maneuverability to avoid attacks. Current missiles / target drones mostly use the aerodynamic force of the rudder surface as the maneuvering control means in flight. It is difficult for the aircraft using this kind of non-vector jet power to achieve high maneuverability by relying on...
