Abstract

According to Federal Aviation Administration (FAA) statistics on mechanical failures, tail rotor failure is the third highest cause of fatal accidents in helicopters. Tail rotor failure represents a serious hazard to personnel and mission objectives and can create high fiscal loss. This is especially true for unmanned helicopters, which cannot be equipped with the fail-safes standard on manned counterparts. This work provides an overview of how a helicopter can be controlled after a tail rotor failure and its applicability to both manned and unmanned vehicles. This work specifically details some of the limitations of this type of software failure control.
