Problems solved by technology

When the parallel hanger is put into the CTS test as a whole, the hanging object is composed of three parts, such as a hanging beam and two parallel launching racks. It is necessary to measure the six-component aerodynamic force of these three parts as a whole, and there is no suitable method for this test at home and abroad. conditional strain balance

Abstract

The invention discloses a six-component multi-piece beam type balance for parallel hanging rack CTS (Compatibility Test Suite) testing. The balance comprises two launching racks, a hanging rack and anL-shaped hanging rack, wherein the two launching racks are connected through a reinforcing beam; a hanging elastic model is fixedly connected with below each launching rack; the hanging rack is positioned between the two launching racks and is connected with the reinforcing beam; the L-shaped hanging rack is positioned above the hanging rack; one end of the L-shaped hanging rack is connected withthe hanging rack through a plurality of I-shaped beams; the other end of the L-shaped hanging rack is connected with a six-freedom degree mechanism; the two launching racks, the hanging rack and theL-shaped hanging rack are of an integral structure; a balance is arranged on the L-shaped hanging rack. By adopting the balance, CTS testing can be successfully caused out in a wind tunnel of a magnitude of 1.5m, a good base can be made for relatively real parallel hanging rack CTS testing simulation in a relatively large wind tunnel in the future, and testing result data as technical support canbe provided for design of parallel hanging racks.

Description

technical field [0001] The invention belongs to the technical field of aeronautical aerodynamic wind tunnel tests, and in particular relates to a six-component multi-plate beam balance used for parallel hanger CTS tests. Background technique [0002] The CTS test of the overall launch of the parallel bombs is mainly to measure the aerodynamic force of the parallel bombs, pylons and launchers. At present, the CTS test balance mainly uses a single tail support balance, which is only suitable for measuring the aerodynamic load of the missile model when simulating a single missile launch. When the parallel hanger is put into the CTS test as a whole, the hanging object is composed of three parts, such as a hanging beam and two parallel launching racks. It is necessary to measure the six-component aerodynamic force of these three parts as a whole, and there is no suitable method for this test at home and abroad. Conditional strain balance.
