Embodiment Construction

[0022] figure 1 Among them, the upper engine 1, the combined nozzle 5, and the lower engine 9 form a combined engine, and the combined nozzle 5 generates a vector thrust composed of an axial force Fx, a vertical force Fy, a pitching moment Mz and a rolling moment Mx. The upper engine 1 is fixed on the front mounting frame 2 through the first main mounting section 3 and the first auxiliary mounting section 4; the lower engine 9 is fixed on the front mounting frame 2 through the third main mounting section 8 and the third auxiliary mounting section 10; The combined spray pipe 5 is fixed on the rear mounting frame 6 through the second main mounting section 11 and the second auxiliary mounting section 7 .

[0023] Loads such as engine axial thrust Fx, vertical thrust Fy, gravity G and maneuvering overload are transmitted to the stand by the main installation section and the auxiliary installation section. The main installation point constrains the axial thrust, vertical force, an...

Abstract

Disclosed is a distributed measurement device for measuring the vector thrust of a combination engine comprising two or more aeroengines, the distributed measurement device comprising a support assembly, an installation assembly and a measurement Assemblies, wherein: the combination engine is installed and fixed to the support assembly through the installation assembly; the measurement assembly is arranged on the installation assembly, the measurement assembly collects the thrust generated when two or more aero-engines are running, and uses the collected thrust to obtain the combination Vector thrust of the engine.

Description

technical field [0001] The invention belongs to the technical field of aero-engines, and in particular relates to a distributed measuring device and method for measuring the vector thrust of a combined engine. Background technique [0002] Thrust is the main parameter for evaluating aircraft and engine performance. With the improvement of fighter technical indicators, thrust vector technology has become one of the symbolic technologies of the fourth generation fighter. And supersonic cruise capability, greatly improving the combat effectiveness and survivability of fighter jets. In the design of aircraft flight control system equipped with vectoring nozzles, it is more necessary to calculate the thrust to carry out diversified control of the engine and the aircraft. Therefore, how to effectively and directly measure the engine thrust has become a common technical problem. [0003] At present, the most widely used vector thrust measurement method is the vector thrust test b...
