本論文係應用DATCOM之經驗公式、圖與表估算一名為Ce-71UAV之空氣動力係數與導數，並分析其配平與穩定特性。DATCOM包含paper DATCOM與digital DATCOM，由於利用前者做分析相當耗費時間、人力與物力，而後者對於特殊外型之機翼所得到的輸出常常會出現N/A(not available)，因此在本論文之研究中自行發展程式，以達到節省時間、人力與物力之目的。
上述自行發展之程式是以Ce-71UAV之幾何外型為基礎進而將部分paper DATCOM之經驗圖表與公式數位化成為資料庫，並且以此資料庫建構之，其中包含輸入檔、執行檔、輸入檔之幾何外型以及飛行狀況範圍限制。以此程式所估算之空氣動力導數與係數，經與利用digital DATCOM所估算之結果驗證吻合。本論文中所發展之程式，可用以分析無人載具之配平與縱向穩定特性。

In this thesis, the empirical formulae, charts and tables in the DATCOM are used to estimate the aerodynamic coefficients and stability derivatives and analyze the trim and stability characteristics for a UAV dubbed Ce-71. DATCOM includes paper documents and digital codes, of which the former will be named “paper DATCOM” and the latter “digital DATCOM.” The analysis using paper DATCOM is usually very time-consuming. On the other hand, although the analysis using digital DATCOM may save a lot of time, it often results in “N/A” (not available) for aircraft with not-so-typical configurations. For this reason, a computer program is developed in this thesis to save time and manpower for the analysis.
By digitizing parts of the empirical formulae, charts and tables in the paper DATCOM which are used in estimating the aerodynamic coefficients and stability derivatives of Ce-71 UAV, this thesis develops a computer program including input files in which the geometry configurations and the flight conditions can be prescribed. The results estimated by using this program are validated with those estimated by using the digital DATCOM. The program developed in this thesis can be used in the analysis for trim and the longitudinal stability characteristics of the UAV.
