Six-component multiple-chip-beam type balance used for CTS (captive trajectory simulation) test of paralleled hanger put in overall

Abstract

The invention relates to a six-component multiple-chip-beam type balance used for CTS (captive trajectory simulation) test of paralleled hanger put in overall. The six-component multiple-chip-beam type balance comprises bomb hanging models, launching racks, a plurality of reinforcing ribs, a pillar beam, a plurality of chip beams and a secondary hanger, a fixed plate is perpendicularly arranged atthe left end of the pillar beam, a lower end face of the right end of the pillar beam is connected with a middle portion of an upper end face of the paralleled hanger through the chip beams, cover plate fixing holes are formed in the left end of the paralleled hanger, strain-gauge array bridges are pasted on the pillar beam and the chip beams, two side walls of the right end of the paralleled hanger are connected with the secondary hanger through the reinforcing ribs, the launching racks are arranged on lower end faces of the secondary hanger positioned below the paralleled hanger, and the bomb hanging models are arranged at the lower ends of the launching racks. The six-component multiple-chip-beam type balance has the advantages that different externally-hung objects on the balance of the paralleled hanger can be tested, high precision and low interference are achieved, connection strength and precision are enhanced since the hanger balance is connected with the externally-hung objects through pin holes and screws, and overall six-component aerodynamic force tests for three main parts including the hanger / launching rack (paralleled) and the like are achieved when the paralleledhanger are put in overall.

Description

technical field [0001] The invention relates to the technical field of aeronautical aerodynamic wind tunnel tests, in particular to a six-component multi-piece beam balance used for the CTS test of the overall placement of parallel hangers. 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.
