Description

TECHNICAL AREA

The The present invention relates to a multifunctional service and Test equipment for unmanned aerial vehicles.

STATE OF THE ART

unmanned Missiles, for example cruise missiles, become Over the course of its lifetime a variety of tests and verifications subjected to continuous service. After production at the factory or after major overhauls at the manufacturing plant, the missiles are there in a final production test (FET) with an extensive test program by means of a corresponding tested complex device configuration. Simplified Tests are delivered to the delivered at specified time intervals and stored in the depot missiles carried out. Likewise, corresponding simplified tests are after a transport the missile and before its use. These tests outside the factory can not performed with the same intensity and test depth as is the case with the factory acceptance test (FET), because the necessary complex test equipment outside of the manufacturer is not available and not mobile is used. Furthermore, the production final acceptance test only by specially trained professionals, who can handle the different test equipment.

One Disadvantage of these simplified tests outside the manufacturer exists in the only small test depth. This leads to, that errors may not be detected or that when detecting an error, a deeper error analysis is not is possible. The missile must then go to the manufacturer be spent there to undergo a more intense test become. This is not only costly and expensive, but requires ammunition containing missiles either the secured transport of a sharp missile or defusing the missile before transport to the manufacturer and the subsequent sharpening of the missile after the return.
