Conceptual Design for Small Solar Powered Uninhabited Aerial Vehicle
Lee, Sang-Hyup ; Park, Sang-Hyuk ; Bae, Jae-Sung ;
Journal of the Korean Society for Aviation and Aeronautics, volume 19, issue 2, 2011, Pages 1~9
Several studies on the development for solar powered uninhabited aerial vehicles(UAVs) are under way as the use of the renewable energy becomes more and more important these days. This paper is for the conceptual design by a discrete and iterative method. An initial design point with 1.5 meter wing span is determined in the global design, which deploys the mass and energy balances among each component of UAV including solar cells and airframe. Then, the iteration for subsystems is carried out with the help of Vortex Lattice Method(VLM) to optimize the aircraft configuration and the solar power system. It is demonstrated in simulations that the optimized design increases the flight time from 62 to 120 minutes when the solar power system is installed. Also, the associated dynamic analysis reveals that the designed small aircraft has the acceptable stability and controllability.

Fault Detection and Identification of Uninhabited Aerial Vehicle using Similarity Measure
Park, Wook-Je ; Lee, Sang-Hyuk ;
Journal of the Korean Society for Aviation and Aeronautics, volume 19, issue 2, 2011, Pages 16~22
It is recognized that the control surface fault is detected by monitoring the value of the coefficients due to the control surface deviation. It is found out the control surface stuck position by comparing the trim value with the reference value. To detect and isolate the fault, two mixed methods apply to the real-time parameter estimation and similarity measure. If the scatter of aerodynamic coefficients for the fault and normal are closing nearly, fault decision is difficult. Applying similarity measure to decide for fault or not, it makes a clear and easy distinction between fault and normal. Low power processor is applied to the real-time parameter estimator and computation of similarity measure.

Michibiki is the first QZSS satellite, which was launched by a H-IIA rocket departing from the Tanegshima in Japan on 11 September, 2010 and now operated successfully. This paper presents the results obtained from processing of the L1 C/A signal transmitted from the QZSS satellite. The acquisition and tracking are performed by the L1 software receiver implemented by ETRI. The signal processing results show that QZSS L1 C/A signal is normally processed through the tracking loop results of FLL, PLL, and DLL, the EPL correlator output, and the C/No output. Finally, the paper demonstrates that the QZSS satellite could be used in the navigation system together with the GPS satellite in Korea.
An Analysis on Structural Relationship between CRS Technology Acceptance and Reuse Intention - Targeting Employees for Domestic Airlines -

The purpose of this study is to closely examine relationship of the system re-use intention depending on CRS technology acceptance. Accordingly, questionnaire was widely distributed to 160 CRS users by convenient sampling targeting people in charge of task among employees for airlines and travel agencies, who are working-level staffs for CRS. Among these things, totally 142 valid materials were used in analysis. The analytical data processing was utilized SPSSWIN VER 18.0 and AMOS 18.0. The findings can be summarized as follows. Influential variables in CRS technology acceptance had significant influence upon the perceived ease use, the perceived usability, and the re-use intention. Also, the significant positive(+) influence was revealed to be had upon the perceived usability by the perceived ease use and upon the re-use intention by the perceived usability and ease use.
The Study on Small Aircraft Transportation System in Higher Volume Opreations

This paper summarizes the HVO concept and procedures, presents a summary of the research and results, and outlines areas where future HVO is required. This concept enables people to get their destinations through shortest paths with advanced air traffic control system and equipments. The concept's key feature is that pilots maintain their own separation from other aircraft using air-to-air datalink and on-board software which are needed for supporting flight information present on the high Way in the sky display and airborne internet. By assigning Self-Controlled Area which assume pilot have separation responsibility, controllers evaluated SATS HVO concept as a successful method on the view of reduced workload and increased traffic level on high volume operation.
A Study on the "Vertrauensgrundsatz" in aviation
Ham, Se-Hoon ; Whang, Ho-Woon ;
Journal of the Korean Society for Aviation and Aeronautics, volume 19, issue 2, 2011, Pages 45~51
The article specified in aviation legislation, 'The captain has the final authority and responsibility in flight safety' could be one reason running counter to applying "Vertrauensgrundsatz". In practice, however, captains do not have professional skills in every task and they should distribute duties and responsibilities to flight attendents and other staffs to operate the flight as safely and efficiently as possible. Therefore, in aviation, fair criterion, namely, "Vertrauensgrundsatz" is necessary to balance between efficiency and legal interest for participants. In addition, when it comes to mutual trust of duty which was the starting point of this study, the standard in mutual advice or interference must be based on the duty specified in air law and flight regulations. Also, pervasive trust will not only be attributed to joint responsibility but an act that cannot be trusted.
A Study on Economic Effects of Airlines caused by introduction of Continuous Descent Approach
Park, Sun-Rae ; Moon, Woo-Choon ;
Journal of the Korean Society for Aviation and Aeronautics, volume 19, issue 2, 2011, Pages 52~57
The procedures of Continuous Descent Approach(CDA) is designed to minimize the thrust required during landing, thereby reducing fuel consumption, noise and emissions compared to conventional approach procedures. Widespread implementation of CDA would result in significant reductions in the environmental impact and aircraft operation costs. This paper estimated the possible economic effects from the perspective of airliners through cost-benefit analysis, provided that the CDA is introduced. It is now proposed that a more comprehensive analysis model, which includes the reduced ATC communication burden between controllers and pilots, not to mention the economic aspect, should be established for the improvement.
Comparative analysis of the fuel consumption during Descent Flight
Shin, Dai-Won ; Kim, Yong-Seok ;

A Continuous Descent Approach(CDA) is defined as a simple, cost-effective, noise and emission abatement technique for any powered aircraft on approach. CDA also can be optimised within energy, speed and safety constraints by avoiding unnecessary flap, air brake and engine thrust. This study includes comparison on fuel consumption between Continuous Descent type and Step Down type by using flight data. In particular, we investigated fuel flow per hour, calibrated airspeed and pressure altitude for all flight time. During descent flight, the fuel consumption of Continuous Descent type was less than the fuel consumption of Step Down type.
