    On the Development of a Scalable 8-DoF Model of a Generic Parafoil-Based Delivery System
    (Monterey, California: Naval Postgraduate School, 2005) Yakimenko, Oleg; Aerodynamic Decelerator Systems Center (ADSC)
    The paper presents an initial move to develop a scalable high-degree-of-freedom model of the parafoilpayload system. The intention is to develop the tool capable of: i) determining basic systemﾒs geometry parameters by observing the video data of the real descend, ii) readjusting the nominal aerodynamic and control coefficients incorporated into the well-established equations of motions, and iii) performing model identification to tune numerous relative variables to achieve the best fit with the real drop data if available. Since in the certain way such a tool would represent some kind of generalization of the modeling efforts undertaken so far, the present paper starts from a comprehensive review of publications devoted to the modeling of parafoil-payload systems. The paper then briefly addressed the current stage of the development of a scalable model. In anticipation of real drop data to validate the approach paper ends with conclusions.

    Autonomous Video Scoring and Dynamic Attitude Measurement
    (Monterey, California: Naval Postgraduate School, 2005) Yakimenko, O.; Dobrokhodov, V.; Kaminer, I.; Aerodynamic Decelerator Systems Center (ADSC)
    The paper focuses on the development and evaluation of an autonomous payload tracking capability for determining time, state and attitude information (TSPI) of all types of airdrop loads. This automated capability of accurately acquiring TSPI data, will reduce the labor time and eliminate man-in-the-loop errors. The paper analyses the problem and then proceeds with the description of the PerceptiVU Target Tracking System (TTS) software adopted for obtaining the TSPI. The key features of this software include a choice of three basic tracking algorithms (dynamic centroid, hottest spot thresholding, dynamic correlation), capability of capturing from both standard analog video sources (such as NTSC and/or RS170) and digital video sources, control of the entire system with an off-the-shelf joystick controller. The paper further describes algorithms to be used in conjunction with the data provided by the TTS to determine systemﾒs state variables. A position estimation solution is based on tracking a payloadﾒs center (or any other predetermined point) by several cameras with known positions. A pose (position and orientation) estimation solution is based on tracking of four distinctive non-coplanar points. Pre-selected and artificially marked points on the moving target cooperatively serve as beacons, therefore providing precise measurements of the line of sign toward these points. This allows unique position and attitude estimation and no need for additional pattern recognition. In conclusion, the paper provides examples of video data processing and parameters estimation.

    Statistical Analysis of Touchdown Error for Self-Guided Aerial Payload Delivery Systems
    (Monterey, California: Naval Postgraduate School, 2013-03) Yakimenko, Oleg; Aerodynamic Decelerator Systems Center (ADSC); Systems Engineering (SE)
    The paper overviews the distributions of touchdown error for a variety of different-weight selfguided parafoil-based payload delivery systems as demonstrated at several Precision Airdrop Technology and Demonstration (PATCAD) events in Yuma, AZ within the period of 2001-2009. The paper aims at establishing the correct procedure to estimate an accuracy of an aerial payload delivery system and also looking at the effect that a guidance law might have on a touchdown error distribution. These approaches and estimates should help a tester community in preparation for the aerodynamic deceleration system (ADS) tests and analysis of their results.
