Description

Helicopter target Technical Field The utility model relates to the technical field of targets, in particular to a helicopter target. Background Helicopter targets play a very critical role in the fields of military training, weapon testing, aerospace research and the like. The simulation system can simulate the flight characteristics and target characteristics of a real helicopter, and provides important reference basis for research and development of various weapon systems, performance evaluation and training of military personnel. In the prior art, the conventional helicopter target adopts a cross structure anti-toppling design when a civil foundation is not used, in an actual application scene, the target development height often needs to be flexibly changed according to specific requirements of a site, when the target development height is higher, the support area of the fixed support base based on the cross structure is relatively fixed and limited, the center of gravity of the whole target is also increased along with the rising of the target development height, when severe weather time is met, under the action of external factors such as wind force, air current disturbance and the like, the moment acted on the target can be obviously increased, and the limited support area is difficult to provide enough anti-toppling moment to balance the change, so that the toppling risk of the support base is greatly increased, the toppling phenomenon can cause serious damage to the target, influence the normal use and the service life of the target, and possibly form threat to peripheral training facilities and personnel safety, and a great deal of manpower, material resources and time cost are consumed for reinstallation and debugging after the target toppling, and the problem of the helicopter is seriously solved.
