该程序是由美国运管局研究中心与美国国家运输安全委员会合作开发的，是一种从空中交通管制（ATC）雷达记录中获取飞机运动时程的技术。该技术利用雷达的距离和方位数据，以及下行链路的高度数据，导出一组扩展的数据，包括空速、升力、姿态角（俯仰、滚转和航向）等。该技术在商业航空事故调查和事故分析中应被证明是有用的数据来源涉及没有机载数据记录器的飞机（如军用、短途和通用航空）。
This program was developed by Ames Research Center, in cooperation with the National Transportation Safety Board, as a technique for deriving time histories of an aircraft's motion from Air Traffic Control (ATC) radar records. This technique uses the radar range and azimuth data, along with the downlinked altitude data, to derive an expanded set of data which includes airspeed, lift, attitude angles (pitch, roll, and heading), etc. This technique should prove useful as a source of data in the investigation of commercial airline accidents and in the analysis of accidents involving aircraft which do not have onboard data recorders (e.g., military, short-haul, and general aviation).

sap5是线弹性结构静动力分析有限元程序。
该程序是美国加利福尼亚大学伯克利分校土木工程教授WILSON和他的博士研究生BATHE等编制。1979.5～1979.7美籍华人学者卞学鐄、张之勇应我国五机部的邀请，在北京工业学院举办有限元学习班，并赠送了该程序。沈阳鼓风机厂、北京汽车制造厂、杭州汽轮机厂、西安六三一研究所、五机部计算中心、二机部遵义计算站、西安红旗机械厂等单位先后进行移植。1980年后陆续调试完毕，投入正常使用。同时对有些工科大学学生进行为期50学时的授课。
SAP5 is a static and dynamic finite element program for linear elastic structures.
The program was compiled by WILSON, a professor of civil engineering at the University of California, Berkeley, and his doctoral student, BATHE. From May 1979 to July 1979, Chinese-American scholars Bian Xuetao and Zhang Zhiyong, at the invitation of the Five Machinery Departments of China, held a finite element course at the Beijing Institute of Technology and presented the program. Shenyang Blower Plant, Beijing Automobile Manufacturing Plant, Hangzhou Steam Turbine Plant, Xi'an 631 Research Institute, Five Machinery Department Computing Center, Second Machinery Department Zunyi Computing Station, Xi'an Red Flag Machinery Factory and other units have been transplanted. After commissioning in 1980, it was put into operation normally. At the same time, some engineering university students teach for 50 hours. (2018-09-03, Fortran, 987KB, 下载28次)

NSEG是美国兰利研究中心推出的飞行器起飞、爬升、巡航、加速、下降、减速和着陆等各个过程分析软件。
NSEG was developed to perform rapid aircraft mission analyses. It is based upon the
use of approximate equations of motion whose form varies with the type of flight
segment. Flight segments considered are takeoff, accelerations, climbs, cruises, descents,
decelerations, and landings. Layered atmosphere options are available. The program can
also be used for flight envelope mapping. NSEG provides the capability to analyze
aircraft missions from low to hypersonic speeds. Realistic and detailed vehicle
characteristics are input to NSEG to permit accurate mission analysis. NSEG allows
engine scaling so as to fit the design under analysis. NSEG contains several approximate
flight path optimization capabilities based on Rutowski energy-like criteria for
considering minimum time or fuel flight segments and maximum range segments during
climb or descent. Takeoff and landing analysis is based on the Air Force Flight
