Our Invention "IFCE- Robot Bird Flying System "is a robot bird flying controllability evaluation system and evaluation method and the evaluation system, a microprocessor B produces stimulus pulse sequences with gradually changed strength according to the preset rule, a microprocessor A is in charge of GPS data analysis and relevant information record, the microprocessor B cooperates with the microprocessor A. The invention is the relevant test data collection of a robot bird to be detected are completed in a cooperated manner, the collected data are processed through a data analysis system of a computer before being converted into a trajectory based on an electronic map, whether the robot bird has the flying controllability or not can judged on the basis of the trajectory and the relevant information, and the evaluation whether the robot bird is qualified or not can be completed. The invention is to a comprehensive evaluation of the robot bird flying controllability can be realized, the prior information required by flight navigation can be acquired, the blindness of subsequent flight navigation tests is reduced, a large amount of invalid repetitive work is avoided, the working efficiency is improved greatly, and the robot bird practical progress can be accelerated. The invention also includes a method of a robot bird, which adopts a proper micro-stimulation signal to timely stimulate an abdominal dorsal median nucleus and a robustus archistriatalis of a thalamencephalon of the bird to lead an active escaping behavior of the bird; thereby guiding the flying behavior of the bird. The invention utilizes the active escaping behavior of the bird resulted from using a micro-electricity to simulate a specific nerve nuclei of the bird, namely using a principle of using the micro-electricity to simulate the nerve nuclei to image 'hurt'to guide the behavior of the bird. The method used for guiding the robot bird of the invention has the advantages that as the principle utilizes the appetence of the bird to avoid hurt, the invention has a powerful guiding function; thereby needing not to train the bird in advance; the robot bird has a huge using value. The invention is a compared with the ground animal, the bird has a larger active space and fast moving speed, thus having a larger application advantage obviously the realistic and potential application is very wide and a modern jet engine inlet protection system that protects against large birds and operates autonomously, that is dormant in routine aircraft operations. The invention take a automatically actuates its protective device(s) only at the immediate point of need, then returning it (them) to a non-interfering position, including a RADAR system and a LIDAR system which detect birds entering the intended flight path of the aircraft, and fast computer-implemented computational algorithms that track and identify those from the detected set that are (1) projected to enter a zone which would lead to ingestion by the engine, and (2) of a size large enough that they would seriously damage the engine if ingested. The invention also includes defensive mechanisms housed in the engine nacelle cowling or center hub, or in the fuselage structure that are instantaneously actuated shortly before arriving at the point of impact to shield, deflect, reduce the size of the approaching bird to an acceptable mass, or destroy it, and, that after the ingestion threat has passed, the devices are stowed/retracted or safely jettisoned. FIG. 1: is a simplified schematic depicting the distributed components of several embodiments of a preferred jet engine protection system.
