Engine i No. fulcrum detection fixture and its composed detection system

Abstract

The invention discloses an engine I-th fulcrum detection clamp and a detection system composed thereof, mainly for solving the problems of lack of a special detector used for detecting sealing performance of the I-th fulcrum of an RD-93 engine and huge detection cost due to complex detection process and incapability of secondary use of a conventional detection device in the prior art. The engine I-th fulcrum detection clamp comprises a gas hood and a base each provided with a recessed surface; the gas hood and the base are detachably connected; the recessed surface of the gas hood faces the recessed surface of the base; the recessed surface of the base is internally provided with a simulation bench; the gas hood communicates with a connection nozzle; the gas hood comprises a first U-shaped frame; an opening of the first U-shaped frame is connected with a first connection bench; the base comprises a second U-shaped frame; an opening of the second U-shaped frame is connected with a second connection bench; and the first connection bench and the second connection bench are detachably connected. Through such a scheme, the purposes of detecting airtightness of the I-th fulcrum of the engine and decreasing the detection cost are realized.

Description

technical field [0001] The invention relates to an engine fulcrum detection device, in particular to a sealing detection jig for the No. 1 fulcrum of the engine. Background technique [0002] The RD-93 engine is the power plant of the FC-1 "Fierce Dragon" fighter. It is a certain type of afterburning engine with high thrust-to-weight ratio improved by the Russian Klimov Design Bureau on the basis of the original RD-33 engine. The "Fierce Dragon" fighter is a third-generation light multi-purpose export fighter independently designed by China and jointly produced by China and Pakistan. It has been equipped with two squadrons in Pakistan. [0003] During the field use of the RD-93 engine, the I, II, III, IV, and V fulcrums must be sealed to prevent oil leakage. However, many engines returned to the factory have oil leakage failures, which cannot meet the sealing requirements and affect the performance of the engine. ; With the gradual increase in the number of Pakistan Air For...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved in the present invention is that there is no detector specially used for detecting the tightness of the No. I fulcrum of the RD-93 engine. The detection process of the existing detection equipment is complicated and cannot be used twice, which makes the detection cost huge
