Abstract

The invention discloses an aviation engine thrust detecting device which comprises a base. The base is fixedly arranged on the ground. A test hole is arranged in the middle of the upper surface of thebase. A pressure device is arranged in the base. The pressure device is composed of a sliding member sleeved in the test hole, a pressure plate which is located in the sliding member and is slidablyconnected with the inner surface of the sliding member, pressure sensors which are fixedly connected with the lower surface of the pressure plate and are uniformly distributed under the pressure plate, and a signal connector which is located on the right side of a pressure sensor and is fixedly connected with the lower middle of the right surface of the pressure sensor. A fixation device is arranged above the pressure plate. A fastening device is arranged above the fixation device. The aviation engine thrust detecting device provided by the invention has the advantages of simple structure andhigh practicability.

Description

technical field [0001] The invention relates to the technical field of aero-engine performance testing, in particular to an aero-engine thrust detection device. Background technique [0002] When an aero-engine leaves the factory or repairs a fault, it is necessary to perform thrust detection and related experiments to generate dynamic changes in thrust under different air pressure conditions, and determine the good condition according to the effect of thrust changes. In the test on the guide rail, because the gravity of the aero-engine is too large, even if the friction factor is small, it may bring a lot of friction, which will affect the objectivity of the test. Contents of the invention [0003] The purpose of the present invention is in order to solve above-mentioned problem, has designed a kind of aeroengine thrust detection equipment. [0004] To achieve the above object, the technical solution of the present invention is an aero-engine thrust detection device, inc...
