Flight test results of flight control performance of Smart UAV were described. Flight test in airplane mode was performed by internal pilot using automatic functions including auto take-off and landing, speed/altitude/heading hold as well as a point navigation and a preprogram mode. It reached to the designed maximum speed at operational altitude. The rotor speed in airplane mode was reduced to 82%...
Collision avoidance of UAV is an important function required from pilots and traffic controller as it intends to fly in the airspace of manned aircraft. It is implemented into Smart UAV which the flight test for automatic take-off, conversion and mission flight was conducted successfully last year. Prior to flight test for collision avoidance, the hardware-in-the-loop simulation (HILS) test is conducted...
Flight test results of flying qualities for Helicopter mode of Smart UAV are described. Flight test items in helicopter mode include manual and automatic stick control as well as hold and navigation flight including automatic take off and landing. One of the main purposes of helicopter mode flight test is to evaluate the handling qualities in low speed region where nacelle angles are greater than...
The ground test results of Smart UAV are described. The ground test consists of HILS, iron-bird test, 4-DOF (degrees of freedom) ground rig test, and tethered hover test. One of the main purposes of ground test is to evaluate the integrated flight control system including a digital flight control computer, GPS/INS sensor, air data sensors, etc as well as ground control system (GCS). The performances...
A scaled flight model of a tilt rotor aircraft for the smart UAV program has been developed. Because the flight characteristics of tilt rotor are not well known, the developed scaled model would be helpful to evaluate flight control algorithm of full scale aircraft. Prior to conducting the flight test of this scaled model, we performed the ground test using the 4-degrees of freedom ground test rig...
