Carrier aircraft support for ground preparation of track capturing test

Abstract

The invention belongs to the technical field of aviation aerodynamic force wind tunnel tests, and relates to a carrier aircraft support for the ground preparation of a track capturing test. The support is characterized in that the support comprises a door-shaped support, a translation mechanism, and a guide rod rocking block mechanism; the translation mechanism comprises a spiral elevator 5, a linear guide rail 6, a sliding block installation plate 7, and a rear support 9; the guide rod rocking block mechanism comprises a servo electric cylinder 1, an electric cylinder support 2, a pitching supporting arm 4, a rear support 9, a first hinge assembly 10, a second hinge assembly 11, and a third hinge assembly 12. The support provided by the invention overcomes a difficulty that a carrier aircraft cannot be supported during the ground preparation for the track capturing test, shortens the state preparation and inspection time of the track capturing test, and improves the utilization efficiency of a wind tunnel.

Description

technical field [0001] The invention belongs to the technical field of aeronautical aerodynamic wind tunnel tests, and relates to an aircraft carrier bracket used for ground preparation of capture track tests. Specifically, it can simulate the test posture of the carrier aircraft in the wind tunnel, and the carrier aircraft support device used to capture the track test ground preparation. Background technique [0002] The capture trajectory test is a special wind tunnel test to study the safety characteristics of the separation of the external store and the carrier aircraft. In the test, the separation of the external store and the carrier aircraft is realized by a six-degree-of-freedom motion mechanism. Among them, the carrier aircraft is supported by a wind tunnel model bracket to realize its pitch angle change, and the external objects are supported by a six-degree-of-freedom motion mechanism. It is a necessary condition to ensure the smooth progress of the test to adjus...
