Problems solved by technology

[0002] According to the latest U.S. joint use specification guide "Crash Protection Manual for Aircraft Crew Systems" (JSSG-2010-7), in the longitudinal crash test of a full-scale general-purpose aircraft, the entire aircraft needs to be accelerated to a horizontal speed of 12.2 m / s , and to ensure the stability of the posture, it is difficult to implement. At present, there has been no test in this area in China

Abstract

The invention discloses a general-purpose plane longitudinal horizontal crash test device and a general-purpose plane longitudinal horizontal crash test method. The device comprises the following components of: a plane test piece which is led out through a first steel cable and is connected with a hook of a second steel cable; an upper fixing bracket which is fixedly connected with the plane test piece through a plurality of suspension steel cables; a hoisting device; and a crash platform. According to the general-purpose plane longitudinal horizontal crash test device and test method of the invention, simple pendulum movement and the principle of conservation of energy are utilized, such that the plane test piece can reach a predetermined speed, and therefore, the general-purpose plane longitudinal horizontal crash test device and test method have excellent universality, and a large-sized power device is not required to be specially manufactured to accelerate the plane test piece, and the vertical axis of the plane test piece is parallel to the ground, and the plane test piece can crash with the crash platform before the plane test piece at a 12.2 m / s longitudinal horizontal speed; a suspension system is designed ingeniously, and therefore, the plane test piece can constantly maintain a horizontal attitude in a hoisting process and in a down-sliding process; and excellent yaw correction and plane swing prevention effects can be realized.

Description

technical field [0001] The invention belongs to the technical field of aircraft design, and relates to a test device and a test method, in particular to an aircraft longitudinal horizontal impact test device and a test method. Background technique [0002] According to the latest U.S. joint use specification guide "Crash Protection Manual for Aircraft Crew Systems" (JSSG-2010-7), in the longitudinal crash test of a full-scale general-purpose aircraft, the entire aircraft needs to be accelerated to a horizontal speed of 12.2 m / s , And to ensure the stability of the attitude, it is difficult to implement, and there has not been any test in this area in China. Contents of the invention [0003] The purpose of the present invention is to provide a kind of device and the method of aircraft longitudinal full-machine horizontal impact test, make the longitudinal axis of aircraft test piece parallel to the ground, and just hit with the longitudinal horizontal velocity of 12.2 mete...
