Development of a Robot Ornithopter 'Songgolmae'
Chang, J.W. ;
Journal of the Korean Society for Aviation and Aeronautics, volume 11, issue 1, 2003, Pages 5~16
The present study was carried out to develop highly efficient RC ornithopter 'Songgolmae' powered by motor and battery. Designed electric ornithopter, which has the dimension of O.88m(W)
0.15m(H), is smaller than a conventional ornithopter. This ornithopter weighs 277 grams and has 3 channels radio control. It runs on an electric motor by a lithium polymer battery and has a gear ratio of about 75
95 to 1 to flap its 88 cm wingspan. The aerodynamic performance of the ornithopter, applied to a flapping motion only, was validated by flight tests. Flight times have exceeded 23 minutes until the battery was used up. The flight test results indicate that the ornithopter developed here has sufficient thrust to propel itself in a forward flight. From the economical point of view and the handling of the RC ornithopter, it can be said that the developed robot ornithopter is an effective RC ornithopter. This robot ornithopter flies its way high into the sky just like a real bird flies. The robot ornithopter is used for a wide range of missions.

A Study on Recognition Level's of Flight Professor's for Curriculum Score vs Flight Practical Skill Score in Flight Educations
Choi, Y.K. ; Choi, Y.C. ;
Journal of the Korean Society for Aviation and Aeronautics, volume 11, issue 1, 2003, Pages 27~40
For the flight education, it needs a lot of money. Most of people become airline transportation pilots after completing a course. Therefore it is important to select superior students who adapt themselves to flight for flying education. At present, students who have a good high school record and SAT(Scholastic Aptitude Test) are chosen, and educated at Hankuk aviation university, department of aeronautical science and flight operation. This research studies the professor's recognition of the relationship between practical flight skills and high school record, university grades, and SAT grades.. On this analysis result, there are significant differences between belonging education, completion and work experience.
Development of Calibration Jet System for Calibrating a Flow Sensor
Chang, J.W. ; Byun, Y.H. ;
Journal of the Korean Society for Aviation and Aeronautics, volume 11, issue 1, 2003, Pages 41~55
A calibration jet system using separate blower is developed to calibrate a flow sensor effectively. Designed open circuit type mini calibration jet system, which has the dimension of
is small compared with conventional calibration jet systems. The exit of nozzle has exchangeable contractions with a cross section area of
, and a cross section area of
, respectively. The ranges of wind speed at exit of exchangeable nozzles are
, respectively. The input power for the high pressure blower is 1.18kW. The turning vanes for corner was rolled flat plate parallel to the flow direction. The flow conditioning screen was located immediately downstream of the wide-angle diffuser. The honeycomb and two flow conditioning screens were located in the stagnation chamber. From the economical point of view and the simplicity of the calibration jet system set up and handling, it can be said that the developed calibration jet system is an effective calibration jet system. This system can also be used to calibrate the flow sensor with high resolution.
The analysis of flight data of A321 & A330 aircraft with lift angle
Shin, D.W. ; Jin, Y.K. ; Kim, I.Y. ; Kim, C.Y. ;
Journal of the Korean Society for Aviation and Aeronautics, volume 11, issue 1, 2003, Pages 57~66
This study is performed to secure the safety of civil aviation by establishing systematic analysis ability of Flight Data Recorder. Through this study, we analysed the flight data of A321 & A330 aircraft with lift angles and take-off actions of flight crew members.
The analysis of flight data of aircraft with carry diversion into execution in -flight
Lee, K.C. ; Lee, J.H. ; Song, B.H. ; Shin, D.W. ;
Journal of the Korean Society for Aviation and Aeronautics, volume 11, issue 1, 2003, Pages 67~80
This study is performed to secure the safety of civil aviation by establishing systematic analysis ability of Flight Data Recorder. Through this study, downloading SSFDR(Solid State Flight Data Recorder) to personal computer, editing interface file, flight data numerical analysis and regulations relayed to the aircraft with carry diversion into execution are performed. In the analysis, the flight data of B747-400 model aircraft between Jeju(RKPC) and Gimpo(RKSS) was selected.
